Gregory Vs Gibson

I hate this module

What was gibson’s background that lead him to theorise about perception

Training WW2 pilots

What is the outline of gibsonian perception?

Perception happens from the bottom up with no neural input

Gibson suggests that we use consistent elements like, textures, gradients and linear geometry to fully perceive phenomena like depth and size. what is the name given to these elements?

Functional invariants

When we approach an object in the environment, what happens to the textures?

They become more spaced out

What is the term given by Gibson to describe the idea that objects appear to flow from one point beyond the horizon?

Visual flow

What is the general term given to the geometry of light that is perceived in our eye?

Optic array

What was the name and date of the experiment that proved that adjustments to the optic flow can throw toddlers off balance?

The swinging room 1974

In what environments does the Gibsonian approach to perception look the strongest?

Aviation, driving and on clear days

What might be a reason to why Gibson was so obsessed with the idea of visual flow from the horizon and disappearing textures?

He developed his approach through training pilots

Why did Gibson discount experiments of perception using illusions?

Illusions are not ecologically valid

What is an optical illusion that can be experienced in the environment that Gibson did not account for?

Induced motion, the waterfall

Gibson suggested that we perceive all elements of the environment with no bias and in a holistic manner (aka non cognitive), what might disprove this idea?

Helmholtz environmental regularities, Gestalt psychology, occluded objects

When did Richard Gregory develop his approach for perception?

1970

Outline the Gregory approach to perception?

top-down approaches that uses past knowledge to make inferences about the environment

According to Gregory, what happens to most of the stimulus information when it is being processed in the brain

most of it is lost

According to Gregory, why can’t we just perceive using the stimulus information from our eye?

Stimulus information is ambiguous until we pair it with memory

How did optical illusions like the Necker Cube support Gregory’s approach to perception?

Ambiguous illusions can have two different perceptions based on what knowledge we are using

How did some optical illusions like the Muller-lyer illusion contradict Gregory’s approach to perception?

We cannot change our ‘Hypothesis’ once we perceive the illusory effect

If perception requires past memories and experience, what assumption is Gregory making about newborns?

Newborns cannot see post-partum

How does evidence from developmental psychology contradict the Gregorian approach to perception?

Slater has shown that infants have an understanding of phenomena like size constancy post-partum

True or False: Gregorian perception ignores the fact that we rely on some visual cues from our environment

True
