This document contains a list of 12 names and ID numbers. It then discusses various concepts related to perception, including how past experiences and expectations can influence what we perceive. It describes several perceptual tendencies like proximity, similarity and closure. It also discusses perceptual constancies, size and shape constancy, and instances that can yield false interpretations like mirages. Pattern recognition and top-down and bottom-up approaches to perception are mentioned. Finally, it discusses distance perception cues including monocular cues like size and motion parallax and binocular cues like convergence and retinal disparity.

4. WE OFTEN SEE AND HEAR WHAT WE WANT TO SEE AND
HEAR, BASED UPON OUR PAST EXPERIENCES, INTERESTS,
MOTIVES, EXPECTATIONS; TO STAY WITH IN OUR
COMFORT ZONE

6. THE PERCEPTUAL TENDENCY TO
ORGANIZE STIMULI INTO COHERENT
GROUPS
1) PROXIMITY
2) SIMILIRETY
3) CONTINUITY
4) CLOSURE
5) CONNECTEDNESS

7. PERCEPTUAL CONSTANCIES
1) Size constancy
2) Shape constancy
3) Relative constancy
4) Brightness constancy
SIZE CONSTANCY
SHAPE CONSTANCY

9. INSTANCES IN WHICH PERCEPTION YIELDS FALSE INTERORETATIONS OF
PHYSICAL REALITY
1)PHYSICAL PROCESS:
ILLUSION DUE TO DISTORTION OF PHYSSICAL CONDITION INCLUDE
MIRAGE, IN WHICH WE PERCEIVE THINGS THAT ARE NOT REALLY THERE

10. 2) COGNITIVE PROCESS
a) ILLUSION OF SIZE
b) ILLUSION OF SHAPE OR AREA
ILLUSION OF SIZE
CAUSES OF SIZE ILLUSION
A) SIZE CONSTANCY
B) LEARNING

11. SIZE CONSTANCY
LEARNING

12. 2) ILLUSION OF SHAPE OR AREA
a) MOON ILLUSION
b) POGGENDORF ILLUSION
a) MOON ILLUSION
b) POGGENDORF ILLUSION

13. ILLUSION OF TOUCH AND AUDITION

14. PATTERN
It can be argued that perception is a practical process, for it living organisms with
information essential to survival in their normal habitat.

15. 1) PATTERN RECOGNITION
a) TEMPLATE MATCHING THEORY:
we have many templates, or specific patterns, stored in our memories for various
visual stimuli that we encounter.
b) PROTOTYPE MATCHING THEORY:
Representations in memory of various objects or stimuli in the physical world.

16. BOTTOM UO APPROCH
ABILITY TO RECOGNIZE SPECIFIC PATTERNS
BASED ON SIMPLER CAPABILITIES TO
RECOGNIZE AND COMBINE CORRECTLY
LOWER LEVEL FEATURES
TOP DOWN APPROCH
We often proceed in accordance with what our past experience tells us to expect, and
therefore we don’t always analyze every feature of most stimuli we encounter.

17. DISTANCE PERCEPTION
OUR IMPRESSIVE ABILITY TO JUDGE DEPTH AND DISTANCE OCCURS BECAUSE WE
MAKE USE OF MANY DIFFERENT CUES IN FORMING SUCH JUDGEMENT
THESE CUES ARE DIVIDED INTO TWO CATEGORIES
1) MONOCULAR CUES
2) BINOCULAE CUES
MONOCULAR CUES:
a) SIZE CUES
b) LINEAR PERSPECTIVE
c) TEXTURE GRADIANT
d) ATMOSPHERIC PERSPECTIVE
e) OVERLAP
f) HEIGHT CUES
g) MOTION PARALLAX

18. BINOCULAR CUES
a) CONVERGENCE
b) RETINAL DISPARITY
