Back 3

Course detail/movement

Front 4

Top-down process of perception

Back 4

Use knowledge of the structure of the world to influence perception (conceptually driven)

Front 5

Bottom-up process of perception

Back 5

Use only information coming into the eye to make judgements on the nature of the visual world (data-driven)

Front 6

Top-down processing
Constructivist approach

Back 6

HELMHOLTZ
Perception is an active constructive process
End-product of external stimuli and internal factors e.g. hypotheses expectations and motives therefore prone to error

Front 7

Top down processing
Constructivist approach

Back 7

GREGORY
Perception is the dynamic searching for the best interpretation demonstrated by:
Perceptual constancy
Illusion

Front 8

Perceptual constancy

Back 8

View objects eventhough their true properties aren't reflected in the retinal image
Shape constancy (circular cup looks elipse)
Orientation constancy (world doesn't tilt as you tilt your head)
Location constancy (world stays constant eventhough we're constanly moving

Front 9

Gregory
4 types of visual illusion

Back 9

Distortion-Muller-Lyer arrows (perceptual error)
Ambiguous figure-Rubin's vase (different interp)
Paradoxical figures-Penrose triangle (3D assumptions)
Fictions-Kanizsa triangle (perceive absent)

Milner and Goodale
Info form primary visual cortex diverges into 2 anatomical streams

Back 10

Dorsal=Vision for action, posterior parietal cortex
Ventral=Vision for identification, interior temporal cortex
