EDUCATIONAL PSYCHOLOGY
Meaning, Nature and Scope of
Educational Psychology
What is Psychology?
The word, ‘Psychology’ is derived from two Greek words, ‘Psyche’ and
‘Logos’. Psyche means ‘soul’ and ‘Logos’ means ‘science’. Thus psychology was
first defined as the ‘science of soul”.
According to earlier psychologists, the function of psychology was to
study the nature, origin and destiny of the human soul. But soul is something
metaphysical. It cannot be seen, observed and touched and we cannot make
scientific experiments on soul.
In the 18th century, psychology was understood as the
‘Science of Mind’. William James (1892) defined psychology as the science of
mental processes. But the word ‘mind ‘ is also quite ambiguous as there was
confusion regarding the nature and functions of mind.
Modern
psychologists defined psychology as the “Science of Consciousness”. James Sully
(1884) defined psychology as the “Science of the Inner World”. Wilhelm Wundt
(1892) defined psychology as the science which studies the “internal
experiences’. But there are three levels of consciousness – conscious,
subconscious and the unconscious and so this definition also was not accepted
by some.
Thus psychology first lost its soul, then its mind and then its
consciousness. At present only its behaviour exists. William McDugall (1905)
defined psychology as the “Science of Behaviour”, W.B. Pillsbury (1911) and
J.B. Watson (1912) also defined psychology as the science of behavior.
Behaviour generally means overt activities which can observed and
measured scientifically. But one’s behaviour is always influenced by his
experiences. So when we study one’s behaviour we must also study his
experiences.
Psychology should, therefore, be defined as a “science of behaviour and
experiences on human beings” (B.F. Skinner)
According to Crow and Crow, “Psychology is the study of human behaviour
and human relationship’”.
What is Educational
Psychology?
Educational psychology is that branch of psychology in which the
findings of psychology are applied in the field of education. It is the
scientific study of human behaviour in educational setting.
According to Charles. E. Skinner, “Educational psychology deals with the
behaviour of human beings in educational situations”.
Thus educational psychology is a behavioural science with two main
references– human behaviour and education.
Education by all means is an attempt to mould and shape the behaviour of
the pupil. It aims to produce desirable changes in him for the all-round
development of his personality.
The essential knowledge and skill to do this job satisfactorily is
supplied by Educational Psychology. In the words of E.A. Peel, “Educational
psychology helps the teacher to understand the development of his pupils, the
range and limits of their capacities, the processes by which they learn and
their social relationships.”
In this way, the work of the Educational Psychologists resembles with
that of an Engineer, who is a technical expert. The Engineer supplies all the
knowledge and skill essential for the accomplishment of the job satisfactorily…
for example, construction of a bridge.
In the same way Educational Psychologists, who is a technical expert in
the field of Education, supplies all the information, principles and techniques
essential for understanding the behaviour of the pupil in response to
educational environment and desired modification of his behaviour to bring an
all-round development of his personality.
Thus, Educational Psychology concerned primarily with understanding the
processes of teaching and learning that take place within formal environments
and developing ways of improving those methods. It covers important topics like
learning theories; teaching methods; motivation; cognitive, emotional, and
moral development; and parent-child relationships etc.
NATURE OF
EDUCATIONAL PSYCHOLOGY
Its nature is
scientific as it has been accepted that it is a Science of Education. We can
summarize the nature of Educational Psychology in the following ways:
1. Educational
Psychology is a science. (Science is a branch of study
concerned with observation of facts and establishment of verifiable general
laws. Science employs certain objective methods for the collection of data. It
has its objectives of understanding, explaining, predicting and control of
facts.) Like any other science, educational psychology has also developed
objective methods of collection of data. It also aims at understanding,
predicting and controlling human behaviour.
2. Educational
Psychology is a natural science. An educational
psychologist conducts his investigations, gathers his data and reaches his
conclusions in exactly the same manner as physicist or the biologist.
3. Educational
psychology is a social science. Like the
sociologist, anthropologist, economist or political scientist, the educational
psychologist studies human beings and their sociability.
4. Educational
psychology is a positive science. Normative science
like Logic or Ethics deals with facts as they ought to be. A positive science
deals with facts as they are or as they operate. Educational psychology studies
the child’s behaviour as it is, not, as it ought to be. So it is a positive
science.
5. Educational
psychology is an applied science. It is the
application of psychological principles in the field of education. By applying
the principles and techniques of psychology, it tries to study the behaviour
and experiences of the pupils. As a branch of psychology it is parallel to any
other applied psychology. For example, educational psychology draws heavily
facts from such areas as developmental psychology, clinical psychology,
abnormal psychology and social psychology.
SCOPE OF
EDUCATIONAL PSYCHOLOGY
The scope of
educational psychology is ever-growing due to constantly researches in this
field. The following factors will indicate the scope of educational psychology:
1. The
Learner. The subject-matter of educational
psychology is knitted around the learner. Therefore, the need of knowing the
learner and the techniques of knowing him well. The topics include – the innate
abilities and capacities of the individuals, individual differences and their
measurements, the overt, covert, conscious as well as unconscious behaviour of
the learner, the characteristics of his growth and development and each stage
beginning from childhood to adulthood.
2. The Learning
Experiences. Educational Psychology helps in
deciding what learning experiences are desirable, at what stage of the growth
and development of the learner, so that these experiences can be acquired with
a greater ease and satisfaction.
3. Learning
process: After knowing the learner and
deciding what learning experiences are to be provided, Educational Psychology
moves on to the laws, principles and theories of learning. Other items in the
learning process are remembering and forgetting, perceiving, concept formation,
thinking and reasoning, problem solving, transfer of learning, ways and means
of effective learning etc.
4. Learning
Situation or Environment. Here we deal with
the environmental factors and learning situations which come midway between the
learner and the teacher. Topics like classroom climate and group dynamics,
techniques and aids that facilitate learning and evaluation, techniques and
practices, guidance and counselling etc. For the smooth functioning of the
teaching-learning process.
5. The Teacher: The teacher is a potent force is any scheme of teaching and learning
process. It discusses the role of the teacher. It emphasizes the need of ‘knowing
thyself’ for a teacher to play his role properly in the process of
education. His conflicts, motivation. Anxiety, adjustment, level of aspiration
etc. It throws light on the essential personality traits, interests, aptitudes,
the characteristics of effective teaching etc so as to inspire him for becoming
a successful teacher.
Though the entire
scope of Educational Psychology is included in the above mentioned five
key-factors, it may be further expanded by adding the following:
6. It studies Human
Behaviour in educational situations. Psychology
is the study of behaviour, and education deals with the modification of
behaviour; hence, educational psychology pervades the whole field of education.
7. It studies the Growth
and Development of the child. How a
child passes through the various stages of growth and what are the
characteristics of each stage are included in the study of educational
psychology.
8. To what
extent Heredity and Environment contribute towards the growth of the individual, and how this knowledge
can be made use of for bringing about the optimum development of the child;
form a salient feature of the scope of educational psychology.
9. Educational
psychology deals with the Nature and Development of the
Personality of an individual. In fact, education
has been defined as the all-round development of the personality of an
individual; personality development also implies a well-adjusted personality.
10. It studies Individual
Difference: Every individual differs from every
other individual. It is one of the fundamental facts of human nature which have
been brought to light by educational psychology. This one fact has
revolutionised the concept and process of education.
11. It studies the
nature Intelligence and its Measurement. This is of utmost importance for a teacher.
12. It Provides Guidance
and Counselling: Education is
nothing but providing guidance to the growing child.
We can conclude by
saying that Educational Psychology is narrower in scope than general
psychology. While general psychology deals with the behaviour of the individual
in a general way, educational psychology in concerned with the behaviour of the
learner in an educational setting.
Cognitive Development
Cognitive development refers to the
gradual growth in what are called cognitive abilities (ability to attend,
perceive, discover, recognize, imagine, judge, conceptualize, remember, learn
and to indulge in meaningful speed) and also to consequent growth in
knowledge and adjustment to the environment. Cognitive development is
influenced by nutritional, emotional and social factors.  In turn
cognitive development affects emotional and social development of the child.
The infant’s first intellectual response
is to stimuli from ‘within’ and gradually as powers of perceiving and attending
develop, it begins to take in stimuli from the outside world.  It’s
intellectual activities broaden as its powers of imagery grow and powers of
retention of past sensory experiences and their recall develop. 
‘Imagination’ gets expressed through play activities by about the age of 3 and
it also serves as a means of intellectual development.  Language,
particularly mother tongue helps in preserving as well as fostering
intellectual growth which continues to accelerate as children develop the
ability to judge, to reason and to solve problems, starting from the concrete
level to abstract level.
Attending
Modern psychologists, who believe in the
integrated functioning of the mind, do not consider ‘attention’ as an
independent faculty or unique power of mind.  As it is a process of an
activity of the mind, it is better to speak of ‘attending’ rather than
‘attention’.  It we are clear that what we are speaking of, is an on going
process or activity, then it is alright to use either of these terms
synonymous, for the same of easy expression and convention.  Whenever we
are awake or conscious, we seem to be attending to something or other, as the
mind when active, has to attend on some stimulus.  As William James
pointed out, field of attention and consciousness are not identical; only a few
contents in the field of our consciousness are selected and attended to. 
Others though experienced by us, may not be clearly and distinctly felt by
us.  Figuratively, we can speak of a margin (fringe) and focus (central
area of clearness) in our field of consciousness.  The terms ‘Figure’ and
‘Ground’ used by Gestalt Psychologists almost correspond to the focus and
margin respectively.  Stimuli that are attended to are in the focus while
others lie in the margin of our conscious field.  The focus and margin
alternate; i.e. the stimulus now in focus may drift to the margin and may be
replaced by some other stimulus, which was earlier in the margin.
Bruner’s
Bruner’s Cognitive
Development Theory
According to Jerome S. Bruner, “A theory of instruction, in short, is
concerned with how, what one wishes to teach, can best be learned, with
improving rather than describing learning”.
Bruner in his book ‘The process of Education’ explained the theories of
instruction.  According to him it is prescriptive since it prescribe rules
for achieving knowledge or skills and guiding techniques for measuring or
evaluating the outcomes.  It will be of normal type since it aims at goals
to be achieved and deals with conditions to meet them.
Bruner has also
suggested four important features of the theory of instruction.  They are:
1.     Predisposition to Learn : Predispose
means, “liable before the event”. This theory is concerned with the experiences
and contexts which will tend to make the child willing and able to learn when
he enters the school.
2.     Structure of Knowledge: It must
prescribe the ways in which a body of knowledge is to be structured so that it
will be easily learnt by the learner.
3.     Sequence : A theory of instruction would
specify the most effective sequence in which the learning materials are to be
presented to the students effectively.
4.     Reinforcement : A theory of instruction must
specify the nature of rewards, moving from extrinsic rewards to intrinsic
rewards.
The developmental
aspect of Bruner’s theory centres around his interest in cognitive development.
CONCEPT FORMATION
Meaning :
The process by which we discover the feature or features which are ‘common’ to
a large number of objects and associate these with a symbol which thereafter
may be applied to other similar objects is called ‘Concept formation’.
Stages / Steps
The process of
formation of concepts involves four elements.  Experience (exploration),
abstraction, generalization and analysis.
Experience is the
process of direct participation in an action.
Generalization is the process of extending the concept to include
objects which possess a quality in common with other objects but which have not
been experienced as any of the objects in the abstracting process.  Quite
obviously, a concept is learned through trial and error reaction to objects,
situations or events.  This refinement and enrichment of a concept depends
upon the number and variety of trial and error reactions of experiences
involved in the development of the concept.
Analysis is the systematic procedure applying techniques for analysis of
academic content which are similar in intent to those employed by task analysis
in designing sequences for a job.
Bruner’s Cognitive
Development Theory
According to Jerome
S. Bruner, “A theory of instruction, in short, is concerned with how, what one
wishes to teach, can best be learned, with improving rather than describing
learning”.
Bruner has also suggested four important features of the theory of
instruction.  They are:
1.     Predisposition to Learn : Predispose

and contexts which will tend to make the child willing and able to learn when

will be easily learnt by the learner.
3.     Sequence : A theory of instruction would

4.     Reinforcement : A theory of instruction must
specify the nature of rewards, moving from extrinsic rewards to intrinsic
rewards.
The developmental
aspect of Bruner’s theory centres around his interest in cognitive development.
Concept Map 
            It is a great use having the concept map in explaining the general
principles formed out of many related ideas.  Concept map is also used to
explain the mutual relationships existing between the various general
principles.  The relationship between various ideas putforth in a lesson
and the way they lead to the general principles are understood with the help of
concept map.
As already told, concept map helps to understand how the different
general principles are themselves related.  It is very useful in preparing
a classified summary of the ideas learnt in a lesson. Here, in the concept map,
starting from a general principle, every idea has to be put in a hierarchical
order. ‘Linkage’ and Cross Linkage’ between the different general principles
are to be indicated.  In preparing the lesson for his class, the teacher
is helped to a large extent by this concept map.
| 
   Psychologists use the term concept
  formation, or concept learning, to refer to the development of the
  ability to respond to common features of categories of objects or
  events. Concepts are mental categories for objects, events,
  or ideas that have a common set of features. Concepts allow us to classify
  objects and events. In learning a concept, you must focus on the relevant
  features and ignore those that are irrelevant (Bourne & colleagues,
  1986). For instance, paperbacks and hardcover editions are all books. But you
  must also discriminate on the basis of relevant features: a stack of papers
  is not a book. What is the crucial feature of a book? Usually it is the
  presence of a binding. Most concepts, however, cannot be identified on the
  basis of a single critical feature.Most of the words we use refer to concepts
  and not to particular things. Proper nouns such as “William James” and
  “California” are exceptions. In learning some of their first concepts,
  children commonly focus not on names but on the functions of objects. For
  example, a spoon is something to eat with, and a pan is something to cook in.
  Other early concepts are based on groupings of objects that are similar in
  some respect: liquid things, moving things, or soft things. Several theories
  have been proposed to explain how we learn concepts. The stimulus-response
  association theory was proposed by Clark Hull (1920). He argued that we learn
  to associate a particular response (the concept) with a variety of stimuli
  that define the concept. For instance, we associate the concept “dog” with
  all of the characteristics of dogs (four legs, fur, tail, and so on) and are
  able to generalize the concept to unfamiliar dogs.The hypothesis testing
  theory was proposed by Jerome Bruner and his colleagues (1956). Bruner
  believed that we develop a strategy of testing our hypotheses about a concept
  by making guesses about which attributes are essential for defining the
  concept. While this tends to be the method used by subjects in an experiment,
  it might not be appropriate in everyday life (perhaps because we often use
  natural concepts rather than formal concepts in everyday life). Eleanor Rosch
  (1978) suggested that the natural concepts in everyday life are learned
  through examples rather than abstract rules. Her exemplar theory proposes
  that we learn the concept of “dog” by seeing a wide variety of dogs and
  developing a prototype of what the typical dog is like. Busemeyer and Myung
  (1988) studied prototype learning in college students by presenting a series
  of exemplars and asking the subjects to reproduce the prototype. This type of
  study allows researchers to gain an understanding of the concept learning
  process. Over the years, everyone is faced with an infinite number of complex
  stimuli. How we choose to group and sort them into concepts will depend upon
  our interests, beliefs, values, and experiences with the environment.
  Consider the concept “job.” To one person it may mean an unpleasant task, while
  to another it is a means of achieving fulfilment. Concept formation is a form
  of thinking that helps us to better understand the world we live in, as well
  as ourselves.  | 
 
Concept Mapping
Social scientists have developed a
number of methods and processes that might be useful in helping you to
formulate a research project. I would include among these at least the
following — brainstorming, brainwriting, nominal group techniques, focus groups,
affinity mapping, Delphi techniques, facet theory, and qualitative text
analysis. Here, I’ll show you a method that I have developed, called concept
mapping, which is especially useful for research problem formulation.
Concept mapping is a general method that
can be used to help any individual or group to describe their ideas about some
topic in a pictorial form. There are several different types of methods that
all currently go by names like “concept mapping”, “mental mapping” or “concept
webbing.” All of them are similar in that they result in a picture of someone’s
ideas. But the kind of concept mapping I want to describe here is different in
a number of important ways. First, it is primarily a group process and so it is
especially well-suited for situations where teams or groups of stakeholders
have to work together. The other methods work primarily with individuals.
Second, it uses a very structured facilitated approach. There are specific
steps that are followed by a trained facilitator in helping a group to
articulate its ideas and understand them more clearly. Third, the core of
concept mapping consists of several state-of-the-art multivariate statistical
methods that analyze the input from all of the individuals and yields an
aggregate group product. And fourth, the method requires the use of specialized
computer programs that can handle the data from this type of process and
accomplish the correct analysis and mapping procedures.
Although concept mapping is a general
method, it is particularly useful for helping social researchers and research
teams develop and detail ideas for research. And, it is especially valuable
when researchers want to involve relevant stakeholder groups in the act of
creating the research project. Although concept mapping is used for many
purposes — strategic planning, product development, market analysis, decision
making, measurement development — we concentrate here on its potential for
helping researchers formulate their projects.
So what is concept mapping?
Essentially, concept mapping is a structured process, focused
on a topic or construct of interest, involving input from one or more
participants, that produces an interpretable pictorial view (concept map) of
their ideas and concepts and how these are interrelated. Concept
mapping helps people to think more effectively as a group without losing their
individuality. It helps groups to manage the complexity of their ideas without
trivializing them or losing detail.

A concept mapping process involves six
steps that can take place in a single day or can be spread out over weeks or
months depending on the situation. The first step is the Preparation
Step. There are three things done here. The facilitator of the mapping
process works with the initiator(s) (i.e., whoever requests the process
initially) to identify who the participants will be. A mapping process can have
hundreds or even thousands of stakeholders participating, although we usually
have a relatively small group of between 10 and 20 stakeholders involved.
Second, the initiator works with the stakeholders to develop the focus for the
project. For instance, the group might decide to focus on defining a program or
treatment. Or, they might choose to map all of the outcomes they might expect
to see as a result. Finally, the group decides on an appropriate schedule for
the mapping. In the Generation Step the stakeholders
develop a large set of statements that address the focus. For instance, they
might generate statements that describe all of the specific activities that will
constitute a specific social program. Or, they might generate statements
describing specific outcomes that might occur as a result of participating in a
program. A wide variety of methods can be used to accomplish this including
traditional brainstorming, brainwriting, nominal group techniques, focus
groups, qualitative text analysis, and so on. The group can generate up to 200
statements in a concept mapping project. In the Structuring Step the
participants do two things. First, each participant sorts the statements into
piles of similar ones. Most times they do this by sorting a deck of cards that
has one statement on each card. But they can also do this directly on a
computer by dragging the statements into piles that they create. They can have
as few or as many piles as they want. Each participant names each pile with a
short descriptive label. Second, each participant rates each of the statements
on some scale. Usually the statements are rated on a 1-to-5 scale for their
relative importance, where a 1 means the statement is relatively unimportant
compared to all the rest, a 3 means that it is moderately important, and a 5
means that it is extremely important. The Representation Step is
where the analysis is done — this is the process of taking the sort and rating
input and “representing” it in map form. There are two major statistical
analyses that are used. The first — multidimensional scaling — takes the sort
data across all participants and develops the basic map where each statement is
a point on the map and statements that were piled together by more people are
closer to each other on the map. The second analysis — cluster analysis — takes
the output of the multidimensional scaling (the point map) and partitions the
map into groups of statements or ideas, into clusters. If the statements
describe activities of a program, the clusters show how these can be grouped
into logical groups of activities. If the statements are specific outcomes, the
clusters might be viewed as outcome constructs or concepts. In the fifth step —
the Interpretation Step — the facilitator works with
the stakeholder group to help them develop their own labels and interpretations
for the various maps. Finally, the Utilization Step involves
using the maps to help address the original focus. On the program side, the
maps can be used as a visual framework for operationalizing the program. on the
outcome side, they can be used as the basis for developing measures and
displaying results.
Horizontal – Vertical
illusion
Illusion is caused
by simultaneous perception of two straight lines, one horizontal and the other
vertical.
4.     Hallucination
A stimuli which is
perceived without an object is called ‘hallucination’.  It is only a sense
experience in the absence of an appropriate external stimuli.  Hence it is
a misinterpretation based on imaginary experience as real
perception.   Dinosaur may be cited as perfect example for
hallucination.
Educational
Implications
1.     Like attention, perception is also one of the important factors in
influencing the behaviour of students.
2.     It is necessary to have accurate perception of objects and events for
effective learning and adjustment.
Perception
            Perception is the process by which we become aware of changes (objects,
qualities or relations) by sense organs.  Mere sensation does not give us
knowledge.  They should be interpreted and defined.  When a sensation
gets meaning it is called perception.  Therefore,
                                            
Perception = Sensation  +  Meaning
            Though perception depends on sensation, the accuracy of perception
depends more on experience, the memories and ideas we get from the past
experiences. Perception is the way we perceive and understand things, objects,
persons and events.  The behaviour of a person depends upon his
perception.  For example, if a student perceives that he is studying well
in his school days, it will give him a hope for better future and he will
involve himself completely in his / her school studies.
Definition
According to  S.S. Sargent, “in a psychological sense
the word ‘Perception’ means both the physical act of receiving sense
impressions (seeing, hearing, smelling etc.) and interpreting these
impressions’.
According to R.S.
Woodworth and D.G. Marquis, Perception is the process of
getting to know objects and objective facts by the use of the senses”.
Characteristics
1.     Perception is meaningful
2.     Perception is selective
3.     Our past experience determines the nature of perception.
4.     It is a synthetic activity
5.     There is analysis also in perception
6.     Both the aspects of analysis and synthesis occur at the same time.
Factors Laws
Perception is sensation strengthened by ideas of various kinds.  We
derive the meaning from sensations by combining them into longer wholes. We
call this process as organization or synthesis.  There are external and
internal factors that determine the organization of the field of perception.
Figure and Ground
Relationship
Figure and ground relationship is an important factor of perceptual
organization.  This means that when we perceive a certain thing we divide
the perceptual field into (i) Figure which is primary and important aspect, and
(ii) Ground which is a secondary or unimportant aspect.  In other words,
we always perceive a figure in its background.  For example, we perceive
words in a page, pictures in a wall and moon in the sky.  In these cases
words, pictures and moon are figures and pages, wall and sky are
grounds. Look at the figure.  What do you perceive? You may perceive
two human faces.  Look at the figure continuously for sometime.  Now
what do you perceive? You may perceive a vase.  When you perceive
twins,  the faces become figure and the vase becomes the ground.
External Factors
§  Proximity 2) Similarity  3) Continuity  4) Closure
§  Proximity :
Proximity means
nearness.  Objects that lie closer form a whole.
A 
B                   
C 
D                    
E 
F                    
G  H
Lines A & B
form one group C & D another group and so on.  Here the factor
isnearness.  We do not see B & C or D, A & E forming a group.
2 Similarity : Elements that are similar in structure or appearance form a
group.           In the above figures, there are
two types of dots.  Because of similarity in figure A we see them as
vertical and in figure B we see them as horizontal.
3.Continuity : When dots lie along a straight lie or curve, they are seen
together.  We ignore the gaps.  Here, the principle involved is
continuity.
4.     Closure
:
Though the figure
seems like 3 lines it resembles a triangle.  Actually it is an incomplete
triangle.  Similarly minor errors are not corrected while in proof reading
also.
Internal Factors :
1.     Past
Experience
            The experiences we have acquired plays an important role while we
organize the field of perception into meaningful wholes.  The world will
be nothing but a confusion if we fail to reckon the past experiences. 
Past experience is retained in the form of images, concepts and ideas of
various kinds.  They are all chiefly the internal condition of the perceiving
mind.  If we fail to take the lessons from past experiences, the world
will be a mass of confusion.  A foreign language is a mere jumble of sound
and noises, when we hear it for the first time.  But if we listen
repeatedly, we can make sense out ot them.  Experience and ideas make us
familiar with the object.  So, familiarity is an important factor that
helps us to organize the field of perception.  When we look at the clouds
on the sky we can see illusions of Elephants and Human faces.  We accept these
figures sine we are familiar with them.
2.     Attitude
or Mental Set
Another important mental condition that determines our perception is
attitude or mental set. A thirsty man sees at a distance a vague figure as a
pot of water.
Errors in Perception
Perception may not be always correct and it may go wrong when a stimulus
is interpreted correctly it is called perception and if it is wrongly
interpreted it is called misperception or error in perception.  If we look
at a rope as necklace, we misunderstand a stimulus. This wrong perception is
called illusion.  Errors in perception occur due to internal or external,
known or unknown reasons.
There are two types of errors in perception namely (i) illusion and (ii)
Hallucination
3.     Illusion
Illusion means “that which does not really exist”.  Hence illusion
is a wrong perception.  Optical illusion can be quoted as an
example.Seeing a rope as a snake is visual illusion.  But if one hears the
voice of a person without seeing him and comes to a conclusion that the voice
is a friend’s voice.  It is auditory illusion.
Piaget’s
PIAGET’S COGNITIVE
DEVELOPMENT THEORY
Jean Piaget (1896-1980) a Swiss psychologist was the first to make a
systematic study of how children develop understanding and thinking.  In
other words, what are the cognitive processes that enable a child to know about
the world.  From countless observations of the thought processes of the
children at different ages,  Piaget traced four concepts and four stages
of cognitive development.
Piaget’s four stages of
cognitive development are :
1.     Sensory Motor Stage
2.     Pre-Operational Stage
3.     Concrete Operational Stage
4.     Formal Operational Stage
1.Sensory – Motor Stage
(Birth to 2 years)
Immediate
experience through the senses is the basis of this sensory motor stage and the
chief intellectual activity is sensory interaction of the environment. 
The child’s activities are physical and without language, to label
experiences.  This stage is characterized by:
1.     Development of sensory, motor and perceptual skills.
2.     Coordination of motor activities.
§  At first, for a child an object ‘out of sight’ is out of kind’. But
towards the close of the second ear it learns ‘Object permanence’ in space and
time.
1.     Development of rudimentary memory;
2.     Gradual progression from reflex behaviour to intentional behaviour;
3.     Development of curiosity, and trial and error exploration of immediate
surroundings;
§  Able to differentiate itself from objects and this is the basis of
self-concept.
Thus, in the
sensory motor stage, practical intelligence like seeing, grasping, sucking etc.
is developed by the child to deal with objects in the environment and symbolic
operations at this stage cannot be utilized.
2.     Pre-operational
stage (2 to 7 years)
The thinking of
pre-operational child is characterized by
1.     Ego-Centrism : (Employing words which have
unique meaning for the child, which limits the child’s ability to comprehend
the views of others);
2.     Animism : (Thinking and treating
inanimate, lifeless things as living objects. For example, children used to
deal with their lifeless dolls as if they are alive.)
§  Realism : (Considering dreams as true and
real e.g. children at this stage pretend stuffed toys are real, have imaginary
friends etc.)
1.     Centring : (the child can concentrate on
only one aspect of a thing at a time).
2.     Due to centring they can not understand that objects are Conserved even
if they change their positions or their shapes altered.
(For instance, If
the child is shown two identical jars A and B containing same quantity of
water, it will accept that they have same amount but it cannot admit if the
water from B is poured into a wide jar C as equal.  The child considers
the height of water column alone without taking into account the breadth of the
jar.  On transferring water from C to B back, again the child will say A
and B are equal.)
1.     Cannot understand reversibility (e.g. what is at your back? The child
answer ‘dog’. Who is in front of the dog? The child says ‘nobody’).  
Irreversibility and ego centricism are related.
§  Consider their parents as omnipresent and omnipotent.
§  Inability to play any game, following the rules.
3. Concrete operational
stage (7 to 11 years)
The child begins to
perform logical manipulations and masters various conservation concepts during
this concrete operational stage.  Classification and seriation become
possible at this stage.  He can also form a mental representation of a
series of acts.  But this is limited to those objects which are
perceivable in the real world.  The child cannot think beyond their self
experiences. (For example, a child of 5 or 6 years age will be able to lead us
to an address asked but may not be able to explain the route, thought it is
familiar with those routes}
Other hallmarks of
this stage are:
1.     transversibility is known; i.e. if A=2B and A=2C, then they can
understand B=C
2.     understand ‘decentring’ (think of more than one quality at a time);
3.     can play any game according to rule;
4.     evaluate crime in terms of magnitude and not in terms of motive
5.     think that their point of view alone is possible and real and do not
believe that there could be other points of view
6.     their thinking is very rigid; do not understand relativistic ideas (e.g.
they believe that morality will be the same in all cultures, at all places, for
all the times).
4. Formal operational
stage (11 years to adulthood)
            1) Thought becomes increasingly flexible and abstract during this stage
of formal operations.  He can carry out systematic experiments and keep a
record of the track of what has been done, consider hypothetical objects and
events, understand abstract ideas and principles.  Theorising and critical
evaluation as well as “putting the possible against the real” are evident at
this stage.
2) Children at this
formal operation stage are able to deal with any problem in a logical
sequence.  Like Scientists they work at it systematically and maintain a
record and ultimately find the solution.
3) The following
characteristics are also exhibited by the children of formal operation stage.
1.     i) Start evaluating acts in terms of underlying motives.
2.     ii) Understand that the rules of any game or social system are developed
by man by mutual agreement and hence could be changed or modified.
iii) They start to
believe that there could be many points of view on any problem though they
cannot knowing them all
1.     iv) Understand that nothing is absolute; everything is relative and
therefore search for the better alternatives is continuously tried, found out
and came with an ideal one.
REASONING AND
PROBLEM SOLVING
Reasoning : Meaning
Reasoning is a
step-wise thinking with an objective mind.  Reasoning is highly conscious,
directed, controlled, active, intentional, forward looking and goal-oriented
thought.  It starts with a definite problem and continues till a solution.
Defining
Munn, “reasoning is combining past experiences in order to solve a
problem which cannot be solved by mere reproduction of earlier solutions.”
Gates and others, “It is a productive thinking in which previous
experiences are organized or combined in new ways to solve a problem”..
Reasoning : Types
1.     Inductive
reasoning
This type of
reasoning implied collection of a large number of facts.  These facts may
be based on the personal experiences of the individual or he might have
collected as a part of his personal study from other sources.  Before
reaching a final decision to act in a particular way the individual carefully
observes facts, tries mentally to experiment with them and finally reaches his
decision to act in a particular way the individual carefully observes facts,
tries mentally to experiment with them and finally reaches his decision to act
in a particular way.
2.     Deductive
reasoning
This type of
reasoning is different from the inductive reasoning.  Here individual has
a readymade rule of action or truth about life.  He has only to apply that
rule on his own problem.  Thus, deductive reasoning is a “method of
application and proof”.
Infact, in our
actual thinking process we sometimes use the one and at other times the other
method.  Sometimes we also combine both these methods.
Problem Solving :
Meaning
The highest level
of learning is considered to be problem solving.  It guides one to solve
problems efficiently.  Changes occur frequently.  Hence an individual
is facing never type of problems for which never ideas are necessary for
solutions.  Hence creation, instead of their repetition, is emphasized in
problem solving.
Problem Solving : Steps
John Dewey
suggested the following steps in problem solving :
1.     Awareness of the Problem : An
individual has to be well aware of the problem.  If he is well-aware there
will be no problem.  If he senses that there is problem he will know the
way to solve it. E.g. what will happen to a boy who is absent continuously?
2.     Recognition of the Problem : The individual
has to comprehend the problem in detail.  He has to understand the problem
by comparing his past experiences he faced with the present problems E.g. All
students recognize the problem as to what has happened to their favorite
monitor.
3.     Collection of data : Collection of data plays an
important part in solving the problems.
E.g. One of the
boys who lives near the monitor’s village goes there.  He learns that his
monitor is suffering from malarial fever.
4.     Formulation of Hypothesis : Hypothesis means “idea or suggestion, put
forward as a starting point for reasoning or explanation”. Hence a
hypothesis may be right or wrong, accepted or rejected after its validity is
verified completely.
1.     Evaluation or Testing of Hypothesis : The
hypothesis formulated is tested when the monitor comes back to school after
recovery from the malarial fever.  He tells that there is a big pond near
his house where water stagnates and breeds mosquitoes. He also tells that one
night he did not use mosquito net because it was a very hot night.
2.     Making of Generalization : finding a
general principle to a particular situation is called making of
generalization.  The following are the generalizations.
A.   One should not sleep without a mosquito net at night in swampy areas,
B.   One should maintain good habits so that the/she may not be attacked by a
disease.
Problem Solving : Role
of the Teacher
The growth rate and
skill in solving the problem is most essential in a student’s life.  Hence
the teacher has to consider the following to inculcate the problem solving
skill in the students.
1.     Moderate Motivation : Motivation is
an essential factor for effective teaching, but extreme motivation will lead to
unwanted emotional tension which may hinder productive thinking.  Hence,
the teacher has to create moderate motivation throughout the classes.
2.     Encourage Divergent Thinking : Divergent
thinking rather than conformity in the behaviour of students is to be
encouraged. The students may be given freedom to deal with the problem in
different ways.
3.     Problem should be presented as a whole :The students
may be allowed to perceive the problematic situation as a whole.  This
will pave the way to solve the problem in an efficient manner.
4.     Level of Difficulty : The problems may be according
to the age and intelligence level of the students.  Extremely easy or
difficult problems should not be given to students.
5.     Active Manipulation : The students may
be encouraged to participate actively in finding out the solution to the
problem. Diagrams, figures and other materials may be presented before the
students at the time of necessity.
6.     Practice : The students may be provided with
required number of similar and related problems which will provide opportunity
to the students for practice
7.     Incomplete Solution of Problems : The teacher
may leave solution as incomplete so that the students will be tempted to find
out the ways to complete the task.
META COGNITION
In the field of
educational psychology, meta cognition is an emerging concept.  Meta
cognitive activities are there in everyone’s daily life.  Meta cognition
enables an individual to become a successful learner.  It is being
associated with intelligence. Meta cognition refers to higher order of thinking
which involves active control over the cognitive process engaged in
learning.  Activities such as planning how to approach a given learning
task, monitoring comprehension and evaluating process towards the completion of
a task are meta cognitive in nature.  Meta cognition is often referred to
as thinking about thinking and it can be used to help students ‘Learn how to
Learn’.  In this way, meta cognition is an essential aspect in the process
of learning.  The gradual growth of cognitive abilities such as ability to
attend, perceive, discover, recognize, imagine, conceptualize remember etc. is
referred as the development of cognitive skills.  It also refers to
consequent growth in knowledge and adjustments to the environment.  The
nutritional, emotional and social factors of the learners influence the
cognitive development.
Implication of 
meta cognition
In successful
learning, meta cognition plays a crucial role.  The study of meta
cognitive activity and development is essential to determine how students can
be taught to better apply their cognitive resources better through meta
cognitive control.  There are several factors such as inadequate prior
knowledge, poor study skills, problems in sustained attention, cultural or
language difference etc affects the successful between cognitive and meta
cognitive strategies concerning the improvement of learning process.
Theories
Psychological Theories
of Attention
Some of the
important psychological theories have been briefly discussed below : Selection
theory of attention
This theory describes as selection among items not yet in consciousness,
a selection of some to enter consciousness while others remain excluded. 
Through such selective action of this mental process, ‘a psychological
environment’ is created out of the physiological environment.  It is said
that Reticular activating system (R.A.S) of the brain is
physiologically responsible for this selection, through a process called ‘Sensory
gating’as R.A.S. filters incoming messages and alerts the higher centers of
the brain when important messages are received.
Hebb’s Theory
This theory considers attention as the activity of the cerebral
cortex.  Hebb considers attending as an autonomous cerebral process which
acts as a rein forcer of sensory processes.  Reinforced response alone
appear for being attended.  Though our brain may experience many sensory
inputs from different stimuli, it allows only the select response of a
particular stimulus get out for being attended.  Thus ‘attending’ is a
process of selection, not of stimulus but of response.
Broadbent’s Theory
This theory based on the present day ‘information theory’, stressed
stimulus selection, as the core of the attentive process.  He uses such
terms like ‘input’.  ‘Short term store’, ‘filter’, ‘limited capacity
channel’, and ‘output’ of the information theory while explaining the basis of
attending.  Broadbent says that the function of attention is to prevent
‘over-loading’ of the individual’s information processing capacity. 
Attention is a filter interposed between sensory input and processing system. 
The filter is all or none, admitting the contents of one input channel at a
time and completely blocking the remainder though it can rapidly shift between
channels.
All the theories agree that in attending, a process of selection takes
place’; they differ only with respect to ‘how much’ and at what stage. 
However Broadbent’s filter model seems to be the most comprehensive
interpretation of attention available though it still has certain deficiencies.
Experimental Findings
on ‘Attending’
Span of Attention
Span of attention refers to the number of independent, distinct or
separate stimuli that can be attended to by an individual, at a glance viz. in
a very brief period of time.  Span of attention (also known as perceptual
span) denotes the number of objects that can exist in the focus at a time.
Determining ‘Span of
attention’ experimentally:
Span of visual attention is found out by using a simple apparatus called
‘Tachistoscope’ which exposes visual material to the subject seated in front of
it, for a very brief period of time (say one second).  Cards using dots of
different numbers are used in such experiments, showing one at a time. 
The maximum number of dots that a person can correctly report three times in
the experiment denotes his span of attention.  This experiment reveals
that the adult span of attention is between 6 to 8, for ungrouped dots. 
This implies that the number of objects that one could attend at any given
moment is limited.  In using flash cards for recognition this has to be
borne in mind by the teacher.  For this reason only, fast moving
automobile vehicles are given registration numbers with digits ranging from 4
to 6.  Similarly telephone numbers and postal pin code numbers are also of
6 or 7 digits.  If numbers containing more digits are used, then they may
not be attended to by us.
Shifting of Attention
We can not be continuously attending on any object for more than 10
seconds, because attention is characterized by ‘fluctuation’.  It shifts
from one object to another or one aspect of the object to another aspect. 
For example, when a student is attending to the lesson taught in the class, his
attention now and then shifts to events that take place and passers by outside
the class but every time returning to the classroom lesson.  Such kind of
shifting in attention is unavoidable.  Fluctuation in attention is
explained as due to sensory fatigue, brain fatigue, periodic muscle waves etc.
If a teacher wants
his pupils to attend to a subject, he should take care to introduce variety,
new points of view, varied illustrations etc. so that wherever their attention
shifts, it would still be related to the subject of instruction.
Division of Attention
Experiments reveal that division of attention is not possible.  We
cannot attentively do two things at the same time.  In conscious
simultaneous performance of two activities, both suffer.
Experiment: An individual is asked to practice writing alphabets from Z down
to A.  Let his practice as many times as possible for a minute. 
After this, he is asked to count aloud in steps of 5, like “3, 8, 13, 18, 23,
28, 33…” and write the number counted last at the end of a minute.  After
this, he is asked to do both writing alphabets and counting numbers
alternatively for a time duration of 1 minute.  Comparing his present and
previous performances it could found that his efficiency in writing alphabets
as well as counting numbers has suffered due to interference.
However some of us
may appear to attend to two activities simultaneously like talking while
knitting a woolen sweater and reading a newspaper while eating.  However,
analysis of the activities will reveal that knitting is done by a girl
habitually without requiring any attention and she attends to talking only;
whenever a mistake occurs in the knitting work, then only she stops talking and
attend to knitting.  Similarly those who had special training will be able
to take on two or more activities simultaneously as they could integrate all
activities into a single unit and alternatively attend to the components of
this single unit rapidly.

External Factors of
Attention
Even if a person is
not interested in any event or object, certain characteristics of the object or
event may compel him to attend to it.  Such object – related factors are
external factors of attention: They are :
1.     Size : Objects of big size, arrest our
attention immediately. Full page advertisements in newspapers capture our
attention more easily than quarter page advertisements.  For the same
reason, people compete in putting up large cut outs of political leaders,
advertisement boarding etc. along the roadside.
2.     Intensity : As size is to figure, so is the
intensity to the quality of the stimulus, with high intensity like loud sound,
deep striking colors, pun chant smell etc, are highly successful in attracting
our attention. While taking a class, if the teacher raises his tone he can
overcome the disturbing noises coming from outside and retain the attention of
his pupils on the on going lesson in the class.
3.     Change : Whenever there occurs sudden
change in a stimulus, it immediately attracts our attention. For example when
the fan suddenly stops, everyone in the class looks up and see the fan. 
Similarly a student sleeping in the class wakes up immediately when silence
suddenly descends on the class.  On entering into our house, we quickly
notice the changed positions of tables and chairs in the hall.  This
implies that if a teachers talks with proper modulation in his voice, he can
easily capture the attention of the students.
4.     Contrast : When a stimulus presents itself
as a contrast in the midst of other stimuli, it turns out to be an attention
winner e.g. A black dot in a white shirt looks predominant. The reason for
drawing the median line on the tar road in yellow colour, men wearing a deep
coloured trouser and light coloured shirt, writing on the blackboard with white
chalk etc;  is to capture our attention through the contrasting nature of
the stimuli involved.  To arrest the attention of students in the class,
the teacher should use contrasting activities like lecturing, questioning,
using charts and writing on the blackboard while teaching.
5.     Novelty : When a stimulus is presented in
a novel or unusual way, it attracts the attention of everyone. For example, we
used to see usually the notice “No admission” in offices; but in an office when
we see the same notice in a different manner like “Admission with permission
only” it immediately strikes our attention and retained in memory for
long.  Similarly, when we see the writing “Don’t kiss me please” on the
back of a lorry instead of the usual writing “Please keep sufficient distance”,
it quickly arrests our attention.  In a similar way, while teaching in the
class if the teacher instead of using the examples given in the text book,
presents illustrations from his personal experiences, and that too relating to
pupils’ immediate environment, then students’ attention will not get out of the
class.
6.     Movement : As compared to stationary
objects, moving objects easily attracts our attention. For this reason only,
the mother of a crying child, to divert its attention, points out to the child
moving objects like a crow, car, aeroplane and the like.  Similarly to win
the attention of the people, advertisers display boarding’s with neon lights
that alternately light up and put off so as to give the appearance of movement. 
The classroom teacher should also present stimulus variation like moving to the
blackboard to write, moving towards students while questioning, using
appropriate gestures while talking etc. and win the attention of the pupils.
7.     Repetition : a stimulus, even of low
intensity if appears repeatedly, it succeeds in winning our attention. The same
business advertisement is repeated many times in mass media like T.V, Radio and
news papers only to attract the attention of consumers.  Human nature is
to notice that stimulus which appears again and again.  To focus the
attention of the students on any important concept of the lesson the teacher
should explain it two or three times with the use of different illustrations
and that too through different words.
8.     Systematic Form : Objects with systematic form
are easily attended to and retained long in our memory as compared to objects
which are incomplete or irregular in form. (e.g. We listen to a faint tune even
in noisy surroundings). To enlist the attention of the students, the teacher
before starting the lesson should give an over-view of the entire lesson so
that the students get a proper and complete idea of the lesson.
Internal Factors of
Attention:
The following are
some of the important factors of attention which operate from ‘within’ us.
1.     Interest: This pays an important role in
eliciting the attention of the grown up adults. One attends to something when
it matters to him intensely even though none of the objective factors are
present.  One’s interest which composes one’s dominant motivational system
determines what one attends to.  The attention of violinist walking along
the bazaar is struck at the shop selling musical instruments, particularly
violins.  Every student during admission to college applies to courses of
his interest.  Students develop certain skills on the basis of their
interest.  (e.g. Musical talent, vocational skill, mathematics ability,
science talent etc. get developed on the basis of interest of individual
students).  Interested students keenly observe the lessons in the
class.  Teachers should always teach in such a way as to kindle the
interest of the students.
2.     Need or Value : Another important subjective
factor determining attention is ‘Need’, For example, the attention of a person
waiting for bus of a particular route will always be restricted to buses of
that route only. A hungry person easily spots the name board of a restaurant,
though it is a small in size, appears dull, but the name board of a near by
bookshop which is big in size may not catch his attention.  Hence if the
teacher before starting a lesson in the class points out the utility of the
concepts to be taught, then students will follow the class with much attention.
3.     Mental Set : One’s mental set or disposition
of readiness to react to a particular stimulus, is another subjective factor of
attention. For example the attention of a person who goes to railway station to
receive his friend will always be on spotting the friend in the midst of
others; He may not even hear if somebody nearby calls him.  The reason for
this is that his mind is set only to receive his friend.  For this reason
only, Herbart stressed the importance of preparing the students for the lesson
at the start of the class, before actually teaching the lesson.
4.     Physiological condition: The
physiological condition of one’s body also determines the level of attention
students suffering from headache, stomachache, fever etc., and will be unable
attend to the lesson taught in the class. It is always better to provide rest
for those students who do not feel well, instead of compelling them to attend
the class.
Types of Attention
Attention are of two
types
1.     Involuntary or Non-Volitional Attention
2.     Voluntary or Volitional Attention
Involuntary Attention
Involuntary
attention is spontaneous, free, natural and passive.  Not much effort is
needed for this type of attention.  Attention of young children is of this
nature.
Voluntary Attention
This type of
attention involves some effort or will.  Some times we have to force
ourselves to attend to object s or events in which we lack interest.  In
such cases, we take efforts to set our attention on the stimulus in
question.  Thus we can say voluntary attention is Intentional.
Sometimes effort is
required to initiate or start attending, which once it has got a start through
effort, then goes on effortlessly.  For example, it may require effort on
our part to start reading a new book.  Once started reading, we may be
absorbed in reading, if the book is well written.  This type of attention
triggered by effort, is known as ‘Implicit Volitional Attention’. 
In another type of voluntary attention, effort may be required continuously to
start as well as sustain attention through out the activity.  Such type of
attention is called ‘Explicit Volitional Attention’.  Most of
the activities carried out without much interest, belong to this category.
What is sometimes
referred to as ‘habitual attention’ is akin to involuntary attention, as
habitually attending to something may make it automatic after some time. (e.g.
the bus drivers attending to traffic signals).  Even in voluntary
attention, interest is present, as without some interest we will not
attend.  In such cases, interest is of an indirect nature rather than
direct and immediate.
Inattention and
Distraction
            Inattention means, not paying attention to a particular stimulus or to
any stimulus. We do not pay attention to a particular stimulus because we are
not interested in it.  Inattention is caused by the absence of objective
and subjective factors that determine one’s attention.  For example, lack
of interest, motivation, or need on the part of the individual cause
inattention.
Distraction, on the
other hand, refers to attending to irrelevant stimuli that are not part of the
main assigned task.  A student would like to attend to the lecture in the
classroom but he may be distracted because of the noise coming from
outside.  Distraction results in poor productivity and wastage of energy
resulting in fatigue.
Role of Interest and
Effort in Attention
            Interest may refer to the motivating force that impels us to attend to a
person, a thing or an activity or it may be the effective experience that has
been stimulated by the activity itself.  In other words, interest can be
the cause of an activity and the result of participation in the activity – Crow
and Crow. According to Bhatia, “Interest means a
difference.  We are interested in certain objects because they make a
difference to us, because they concern us”.
INTEREST AND
ATTENTION ARE INTERRELATED.  We are always ready to attend to objects
which are of interest to us and when we under take a task in which we have more
interest, we attend to it with much involvement.  Thus it could be said
“interest is latent attention’ attention is interest in action
(McDougall).  No effort is required to attending an object in which we
have interest (Involuntary attention).  Even in the case of voluntary
attention where effort is required to attending, some interest is present
(indirect rather than direct and immediate) as without some interest we will
not attend.  For example we take efforts to learn a subject (say
Mathematics) which at times schemes to be tough and uninteresting. We do this
because, the study of that subject though not interesting We do this because,
the study of that subject though not interesting, help us to learn and master
another subject (say engineering) of our choice.
Summing up all
these facts it could be said that we attend to tasks of interest involuntarily. 
Tasks in which we have no direct interest, require our voluntary attention
through deliberate efforts.  Thus it could be concluded that attention is
not possible without interest.
Ways and Means of
securing better attention in the class
1. To secure
attention of pupils, teacher has to first of all remove certain obstacles to
attention.  Poor physical conditions of pupil, fatigue, sensory defects.
etc. interfere with attention. Unhygienic seating, uncomfortable furniture,
inadequate lighting, etc. also hinder attention.
2.     The teacher has to make good use of the objective factors of attention
in his class. Loud voice, striking diagrams, clear blackboard work, use of
coloured chalks, varied activities, novel illustrations, repetition of basic
ideas, etc. are all of such nature.
3.     At the elementary stage the teacher has to appeal to the involuntary
attention by using concrete aids, direct experiences, play activities,
appealing to the children’s curiosity, etc. At the middle school level teachers
can use suitable techniques of motivation by stimulating acquired interest of
pupils, their hobbies, etc. to evoke voluntary attention and foster sentiments
of love for various school subjects and activities. At the adolescent level
voluntary attention has to be evoked by appealing to the long term interests of
students and banking on their self-regard.
4.     During classroom teaching, the teacher has to tell his pupils what to
attend to at the stage of introduction itself by providing the over-view of the
lesson. While explaining a new concept, the teacher should relate it to the
previous knowledge of the students and give examples which are familiar to them
(preferably spotting them from the day to-day life situations).
5.     The teacher should harness the natural interests of pupils to the class
lesson and also create new interests of educational value. Children’s interests
vary with age; but generally all children are interested in creative,
productive, free and life-like activities.  So there is need for play way
methods, projects, discovery, approach to teaching, activity based curriculum,
etc.
Sensation
The other name for
sense organs is “Gateways of knowledge”.  Knowledge is realized through
sense organs.  A blind man cannot realize colour.  The information of
the world is realized by our senses. Hence sense organs are the receptors of
external stimuli.  Tasting, smelling, seeing, hearing and touching are
enjoyed through tongue, nose, eyes, ears and skin.  Incoming stimuli are
realized by sense organs.  The sense organs respond to particular type of
physical energy.
The table gives an
idea of sense organs :

  Sense of touch                              
Touch
Eyes : The eyes are very delicate organs.  Our eyes help us to see and
recognize every thing that is around us.
Ears  : Our ears help us to hear and recognize the different sounds we hear
Nose  : The nose is the organ of smell.  We are able to find out the smell
of pleasant and unpleasant things with our nose.
Tongue : The tongue is the organ of the taste.  There are taste buds
on the tongue.  The taste buds tell us whether the food we eat is sweet,
sour, salty or bitter.
Skin  : Our bodies are covered with skin.  The skin is the organ
of touch.  With the sense of touch we can feel heat, cold, pressure and
pain.  It also helps us to feel soft and hard objects.
Through our sense
organs we can realize the objects, things, persons and events.  The life
and world will be meaningless if the sense organs are absent.  The
conscious mind will be aware of the environment only if the five sense organs
are functioning properly.  The normal functioning of five senses is called
‘sensation’. It comprises of elementary, base and conscious experiences. 
They form the first step in the acquisition of knowledge.
Vision helps us to
see the crowded streets and realize the beauty endowed by nature on
flowers.  Hearing plays on important role in communication with
people.  We can avoid the spicy food drinks etc. by using nose and tongue
(chemical senses).  The sense of touch enables one to feel pain, coldness,
hotness, softness, hardness etc. Types not avl.
