Psychological process in which the sensory

inputs received from the sense organs are

processes , organized and interpreted based

on the past experiences of the organism so

that the nature of the stimuli are

meaningfully understood

Perception=sensation & meaningful

interpretation

There are several factors that may affect the

students ability to perceive they are

Basic needs

Time and opportunity

Goals and values

Elements of threat

Self concept

insight

Gardner Murphy speaks of the four factors of

perception

sensations

Our previous

experiences

Nervous structure

Mental set at the time of experiencing

sensations

Without perception , imagery and

imagination are not possible.

Related to attending and observing.

Perceive only those stimuli that we attend to

Helps to understand the different objects

and events in our environment and learn to

adapt our reactions , towards them.

Process of selection is involved

Perception is largely determined by our past

experiences

Process of integration takes place in

perception

On seeing a man riding a cycle, we do not

perceive the cycle and the rider separately

The mental act of ‘organizing’ takes place

during perception as per the law of pragnanz

Similarly the 12 parallel lines drawn below

are perceived by us as four groups of 3 lines

each.

Wertheimer stated this law as “other things

being equal , the stimuli that are similar ,

will have greater tendency to be grouped as

a single unit”

Closed or completed figures are more stable

than incomplete figures or unclosed figures.

Our minds fills up the gaps if any and

perceive the object as whole and complete.

Organization on perception appears to be

going infinitely in the same direction

Tendency for factors to give direction ,

movement and continuation.

That is why the following series of dots

………………………….. Appear to be in a straight

line.

Arises either because of the ambiguous

qualities of what is perceived or the state of

the perceiving person or both
