Perceptual organization

Question 1

The binding problem

Answer 1

Combining distant elements and features into a whole. A problem that is fixed by perceptual organization: making sense of visual information, even when there’s minimal input.

Question 2

Discrete vision

Answer 2

Rods and cones in the retina sample the image; each looks at a tiny fraction of the image. Information from different parts of the scene are encoded by different neurons. Information about different aspects of the scene (liek color, form, contrast etc) are encoded by different pathways and areas.

Question 3

Characteristics of perceptual organization

Answer 3

Powerful yet automatic

Always tries to make sense of visual information

Effect of experience: once organized, always organized.

Biological motion easy to recognize due to knowledge

Works through psychological and neural mechanisms

Always a dynamic and flexible interplay (fight) between several Gestalt laws operating in parallel

Question 4

Psychological mechanisms

Answer 4

Gestalt laws and texture segregation

Question 5

Neural mechanisms

Answer 5

Selective deficits

Grandmother cells vs assembly coding

Anatomical connections

Contextual modulation
