Perception = Organisation + Interpretation - Coggle Diagram
Perception =
Organisation + Interpretation
Form Perception
organisation of sensations into meaningful shapes and patterns
occurs in accordance with Gestalt Principles, - Ambiguous figures confuses your brain as gestalt principles can yield different solutions when making sense of different info
Similarity
Proximity
Good Continuation
Simplicity
Figure-ground perception
Closure
Depth of distance perception
the organisation of perception in three dimensions
Retinal images are two dimensional and perceptual processes are needed to construct the third dimension of depth
two kinds of visual info provide impt info about depth and distance
Binocular Cues = visual input integrated from two eyes
Retinal disparity = eyes positioned slightly differently which receive different images
convergence = eyes become more crossed when focussing on objects that are closer
Monocular cues = visual input from one-eye
interposition = when one object blocks another, the obstructed object is perceived to be further away
Relative size = when looking at two similar sized objects, the smaller object is perceived as further away
Texture gradient = close objects seem coarser than objects further away, which are perceived to be finer
Motion- Related cues
Parallax = in motion, nearer objects move across visual field faster
Motion Perception
The visual system is wired to detect motion as the rods in the retina are sensitive to it
occurs through convergence on ganglia with big receptive fields
Motion is also detected through neurons in the visual cortex responding to it
the where pathway detects more refined motion
Two systems for processing movement
Eye is stationary when object moves
Eye moves to maintain object at same place on the retina
Perceptual Constancy
We are capable of resolving ambiguous images and identifying them as objects despite the fact that we see them under a tremendous variety of conditions
Shape = we recognise an object as having the same shape although we may view it from a different angle, at a different distance
Size = objects do not differ in size when viewed from different distances
Colour = tendency to perceive object colour as stable even under conditions of changing illumination (seeing red under filters etc)
Interpretation
goes a step further from the four organisational aspects of perception
Object recognition = identifying sensory info and stimuli as a particular object
deeply intertwined with memory
