Question 1
Multiple-choice

Gregory
4 types of visual illusion

Select the best answer

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

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

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

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

Question 2
Multiple-choice

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

Select the best answer

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

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

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

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

Question 3
Multiple-choice

Top-down processing
Constructivist approach

Select the best answer

Concept of ambient optic array

HELMHOLTZ

Question 4
Multiple-choice

Cones

Select the best answer

Course detail/movement

Fine detail/colour

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

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