Perception is the process of interpreting sensory information to produce meaningful objects and relationships. It involves identifying objects, events, or relationships by extracting information from sensations. The organization of perception depends on principles like figure-ground relationship, closure, similarity, proximity, and continuity. Perception can be influenced by factors like sense organ function, brain function, previous experience, psychological state, frequency of exposure, interest, and motives. Errors in perception include illusions, which are false perceptions caused by changes in sensory or brain function, and hallucinations, which are false perceptions without external stimuli.

1. PERCEPTION

2. INTRODUCTION
Perception is the act of interpreting a stimulus
generated in the brain by one or more sense
mechanism.

3. DEFINITION
Perception is indentifying process through which we
interpret and organise sensory information to produce
meaningful objects and its relationship.
Perception is the experience of objects, events, or
relationships obtained by extracting information from
sensation.

4. ORGANISATION OF PERCEPTION
The organization of perception is totally depends
upon fallowing principles
 Principle of figure- ground relationship
 Principle of closure
 Principle of similarity
 Principle of proximity
 Principle of continuity

5. Principle of figure- ground relationship
According to this principle, a figure is
perceived in relationship to its background.
Eg. The words are figures that appear on the back
ground of the phage.

6. Principle of closure
According to this principle, while confronting on
incomplete pattern one tends to complete or close the
pattern or fill in sensory gaps and perceive it as a
meaningful whole.

8. Principle of grouping
According to this principle the tendency to
perceive stimuli in some organized meaningful
patterns by grouping them on some solid basis like
Similarity
Proximity
Continuity

9. Similarity: objects or stimuli that look alike are
usually perceived as a unit.
Eg. Vertical rows of black dots may be seen to form
separate groups in terms of their perception.

10. Proximity:
Objects or stimuli that appear close to one
another are likely to be perceived as belonging to the
same group.

11. Continuity bases:
The objects or stimuli are perceived as a unit or
group on the bases of their continuity.

12. Factors Influencing Perception
 Functions of the sense organs
Functioning of the Brain
Previous Experience
Psychological State
Frequency of Exposure
Interest
Motives

13. Errors in the Perception
 It Means false Perception
Illusion
Hallucination

14. Illusion
 False Perception in presence of Stimuli.
These false perception occurs Bcoz of any one
among following
Alteration in Functions of the sense organs
Alteration in Functioning of the Brain
Psychological State

17. Hallucination
False perception in Absence of Stimuli.
 Auditory Hallucination
 Visual Hallucination
 Olfactory Hallucination
 Gustatory Hallucination
 Tactile Hallucination
