neural firing is only synchronized for…

A

attended stimuli

36

examples of top-down processing

Principles that say many stimuli are ambiguous and ability to interpret relies on similarity, proximity, good continuation, closure, and simplicity

A

Gestalt Principles

38
Q

Associative Agnosia

A

condition where the patient can see but not link the input to visual knowledge
-can draw from memory
-perceive an object, but not recognize it

39
Q

Apperceptive Agnosia

A

patient can perceive an objects features but can’t accurately bind them to perceive the object as a whole

40
Q

small elements that result from organized perception of form

A

features

41
Q

Integrative Agnosia

A

patient has difficulty seeing how multiple features are bound together

42
Q

Influences on errors:

A

1) regularity
2) well-formedness

43
Q

recent firing results in higher starting activation (warm-up effect)

A

recency

44
Q

frequent firing results in higher starting activation (exercise effect)

A

45
Q

In recognition, perfect accuracy is sacrificed for…..

A

A

Face Recognition

47
Q

type of agnosia known as face blindness

A

Q

Detects unexpected but important events without interfering with important current processing

A

Q

How does Reisberg describe attention?

A

Why can’t we process all the info in from of us?

A

We have limited capacity and once we reach that capacity performance declines (circular logic)
