Perception
|
The process of recognizing/organizing and interpretting information

|
Object in external world (Gibson's Perceptual Continuum)

Perceptual Basics
Sensory adaptation |
receptor cells require constant stimulation by ceasing to fire until there is a change in stimulation.
-Constant stimulus reduces sensitivity - Stimulus variation is essential for perception |
|
|
Perceptual Constancies
Size Constancy |
Perception of object size remains the same despite changes in the size of the proximal stimulus.
-The same object at two different distances project different sized images to the retina |
|
|
Perceptual Constancies
Shape constancy |
Perceived object maintains the same shape despite changes in the shape of the proximal stimulus
-the same object at two orientations projects different shaped images on the retina |
