01
Front

What is top-down processing?

Back

Top-down processing is the influence of higher-level knowledge and expectations on how sensory information is analyzed.

02
Front

What does bottom-up processing use to build recognition?

Back

Bottom-up processing builds recognition from features in the stimulus, such as edges, colors, and sounds.

03
Front

How do top-down and bottom-up processing work together?

Back

Top-down processing uses prior knowledge and expectations to guide interpretation; it works together with bottom-up sensory evidence.

04
Front

How can prior expectations speed recognition?

Back

Expectations narrow possible interpretations and direct attention toward useful features, which can make recognition faster.

05
Front

What happens when sensory evidence conflicts with an expectation?

Back

Expectations help resolve ambiguity, but unexpected or strong sensory evidence can lead us to revise an initial guess.

06
Front

What is a context effect in perception?

Back

Context effects occur when surrounding information influences how a target is perceived.

07
Front

How can a familiar scene aid object recognition?

Back

A familiar setting suggests which objects are likely to be present, making an object easier to recognize.

08
Front

How can perception organize a partly hidden shape?

Back

When a shape is partly hidden, perceptual organization can lead people to perceive it as a complete object.

09
Front

What does attention do in perception?

Back

Attention prioritizes some parts of the sensory environment for closer processing.

10
Front

What two kinds of influences can guide attention?

Back

Attention can be guided by stimulus properties, such as a sudden bright flash, and by top-down goals, such as searching for a friend in a red coat.

11
Front

How do expectation and attention differ?

Back

Expectation concerns what is likely to be present; attention concerns what is prioritized for processing.

12
Front

Why can unattended information be harder to recognize?

Back

Because attention is limited, unattended information may be processed less thoroughly, making recognition harder.
