Perceptual Selectivity/Principles of Perceptual Selection:-
Environment consists
of various stimuli. They are in form of objects, animals, sounds, events,
vision, smell and taste etc. All stimuli confront individuals but all can't be
accepted in perceptual process. Some may get accepted and remaining gets
rejected.
Individual accepts
that stimuli which attracts him or beneficial to him. Individual selects the
stimuli which attracts him and reject other stimuli.
For example we watch
some interesting video in you tube ignoring others. Here are various factors influencing in
perceptual sensitivity. They can be studied under two categories:- (i),Internal
attention factors and (ii).External attention factors in perceptual
selectivity.
(i).Internal attention factors in perceptual selectivity:-
The perceptual factors
which exist internally within perceiver are called internal attention factors.
They are cognitive in natures. These factors can be learnt after birth. These
factors can be changed. Individual learns these factors from his surroundings.
(a).Motives:-
It is reason for doing
something. It influences the perception. For example thirst person gives more
importance to water than else.
(b).Expectations:-
It is strong belief of happening something. People see what they want
to see. It influences the perception. For
example People see glasses in goggles frame even if goggles are glass free.
(c).Experiences:-
Experience is knowledge
of doing something in past. It helps to learn or perceive something fast.
(d).Attitudes:-
It is way of thinking
or feeling about something. Attitudes influence the perceptual selectivity. If
someone has negative attitude towards drinking alcohol, then he would think
negative to those who drink once a week or month too.
It is activities which
we enjoy. We perceive quickly those
issues which belong to our deep interests. For example crime is perceived fast
by police than plumber.
(f).Emotions:-
It is strong feeling
created due to one's circumstances, mood and relationship with others. Emotions
influence the perception. For example, if once we perceive one negative, then
we never keep more attention to find his positive attributes.
(vi).Values:-
It is the individual
ethics about right or wrong. For instance, operating porn industry is perceived
good in western culture but it is perceived negatively in eastern culture.
(iv).Personality:-
It stable set of
unique characteristics of individuals. It influences the perceptual
selectivity. For example: will you say day is between nights? Or night is
between days? It can be said that those who see night is between days are
optimists and those who see day between nights are pessimists.
(vi).Learning:-
It is permanent change
brought in behavior through experience. Previous learning helps individual to develop
learning habit. So, he can perceive something than others.
(ii).External attention factors in
perceptual selectivity:-
The perceptual factors
which exist externally outside perceiver are called external attention factors.
These factors can be changed and learnt. Individual get these factors from his
surroundings.
(a).Familiarity:-
It is state of knowing something very well.Familiarity influences on perception. For example:- we recognize our friends even in crowd so faster.
(b).Size:-
Too fat person or too
thin person or too tall person or too short person is perceived so fast than
others.
(c).Intensity:-
Intensity is the
extreme level of power, feeling and energy. It influences extremely in
perception. For instance, loud noise, strong odor, bright light will be noticed
faster than low intensity.
(d).Novelty:-
Individual perceives
new thing fast in comparison of others. People would quickly notice rhino
walking along street.
It is noticeable
differences. External stimuli which are against background are perceived fast.
A shepherd who grazes 25 goats and 1 sheep in a day would remember the sheep
first due to contrast.
(f).Motion:-
Moving objects are
perceived faster than others. Due to it, television use moving text at the
lower part of screen to show news even if another program is being broadcasted.
(g).Repetition:-
Repeated external
stimuli are perceived faster than others. For example students can memorize
lessons by revision for exam preparation.
(h).Sounds:-
Louder and frequent
sound is perceived so faster than lower.
i).Time:-
Time also influences
perception. Students who read at the early morning would understand easily than
other time.
(j).Work Setting:-
If classroom is clean
and peaceful, students learn faster.
(k).Social setting:-
Women wearing short
skirt are perceived faster in eastern culture.
Perceptual Organization/Principle of Perceptual Organization:-
Perceptual organization collects and organizes information about an object in as a whole and provides meaning. It means it does not provide meaning by observing partial information about that objects, it takes as whole information.
It carefully keeps attention towards arriving information and provides meaning. This process completes with involvement of both physical and mental process. It means accuracy of organs, clarity of sensation and mental state are needed to complete process of perceptual organization. Perception is influenced by various factors. Perceptual organization says that perception does not depend mostly on features of individual stimuli. It means perception has just fewer connections with situation of stimuli in hand. Perception is complicated process and there many factors influencing perception besides features of stimuli. The major principles of perceptual organization are such as:-
(i).Figure Ground Relationship:-
According to this principle, perception cannot be made looking just an object. Brain extracts meaning of an object by watching the relationship of object with its background. Objects are not observed in isolation, there features must be also watched.
(ii).Perceptual constancy:-
This principle says that human try to keep perceptual stability about an object by finding permanent features of that object. They make stable perception by identifying stable size, shape, color, experience and other features.
(iii).Perceptual Grouping:-
This principle says that human mind groups many stimuli in easily identifiable patterns. Laws of perceptual grouping are such as:-
(a).Proximity:-It is nearness in space, time and relationship. The thing that is nearby time and physical location is perceived quickly and easily. For example, we are most identified with localities near our house.
(b).Similarity:- It is the state of having same features. If the things are too similar to us, we perceive it easily and quickly. For example, an army person can recognize another army person easily.
(c).Continuity:- Continuously observed things are perceived faster than others. For example: medical terminology is perceived faster by regular medical practitioner.
(d).Closure:- It is tendency of mind to see complete forms anything even if that is incomplete or partially hidden by other objects. For example: we perceive dirty double meaning sentences though spoken half.
