interprets stimuli into a meaningful and coherent picture of the environment in
which s/he lives.
Perception

3. Perceptual Process
Objects in the Environment
Observation
Perceptual selection
Perceptual organisation
Interpretation
Response

4. Perceptual Selectivity
Though people are exposed to several stimuli , they tend to select only a few at a given point of
time, this is perceptual selectivity. Selectivity in Perception which stimuli get selected depends on
two major factors :-
1) Consumers previous experience as it affects their expectations.
2) Their motives at that time for one’s needs, desire & interest etc.
What do you see in
this picture?
Which white circle is
larger?
How would you describe these
potato chips?

5. Factors Influencing Perceptual Selectivity
External Attention Factors
 Intensity
 Size
 Contrast
 Repetition
 Motion
 Novelty and
 familiarity
Internal Set Factors
 Learning
 Expectations
 Motivation
 Personality

6. Intensity
According to the intensity principle of attention, the intensity of an
external stimulus determines its probability of being perceived.
External Attention Factors
Example:
Light Colour Bright Colour

7. Size:
A larger object is more likely to be noticed than a smaller object.
God is great God is great
External Attention Factors
Example:
Which you can read fast?

8. Continued….
Contrast: According to the principles of contrast, the stimuli that contradict most with the
background or the expectations of people receive maximum attention.
Example: Which white square is smaller?

9. Continued….
Motion:
People gives more attention to moving objects than the stationery
objects.
Repetition
The more number of
times a stimulus is
repeated, the more it is likely
to be noticed
Novelty and Familiarity:
New objects in a
familiar situation or
familiar objects in a
new situation draw the
perceiver’s attention.

10. Internal Set Factors
Learning
Learning by itself plays a major role in developing the
perceptual set.
Example:
Hilly
Terrain
Ahead

11. Motivation
The primary motives:
Hunger and Thirst
The secondary motives:
The need for power, The need for affiliation and The need for
achievement.
Personality
Personality of a person influence perception.
Expectations

Perceptual selection is the process by which people filter out irrelevant
or less significant information, so that they can deal with the most
important matters.
