01
Front

What is bottom-up processing in vision?

Back

Bottom-up processing builds information from sensory input, including edges, color, shape, and spatial arrangement.

02
Front

What is top-down processing in vision?

Back

Top-down processing uses context, expectations, knowledge, and current goals to help interpret sensory input.

03
Front

How does visual organization turn light patterns into candidate objects?

Back

The visual system separates regions, assigns borders to figures, groups elements, and parses wholes into parts.

04
Front

What can proximity do to nearby visual elements?

Back

Nearby dots may be perceived as a group, illustrating how proximity can organize visual elements.

05
Front

How can the visual system perceive a partly hidden object?

Back

A partly hidden object may still appear continuous behind an obstruction, helping the visual system form a candidate object.

06
Front

Name visual properties that provide bottom-up grouping evidence.

Back

A contour, alignment, or shared color provides bottom-up evidence that visual elements may belong together.

07
Front

How can context help recognize a blurred object?

Back

Stored knowledge and context help recognition narrow possible identities; a blurred handled object in a kitchen is more likely to be identified as a toaster.

08
Front

What is scene gist?

Back

Scene gist is a rapid, broad impression of an environment, such as a kitchen, street, or forest.

09
Front

How do typical object relationships guide visual recognition?

Back

Typical object relationships guide recognition: a toaster is likely on a counter, and a car is likely on a road.

10
Front

What do likelihood and prior contribute to perception?

Back

Bayesian perception combines the likelihood—how well an interpretation fits visual evidence—with a prior—how plausible it is given context and past experience.

11
Front

How can a sequence change the reading of an ambiguous character?

Back

A shape between letters may be read as B, while the same shape between numbers may be read as 13; the surrounding sequence shifts the interpretation.

12
Front

How do scene and object recognition influence each other?

Back

Scene information can direct attention to likely locations, while recognized objects can refine the interpretation of the scene.
