PSYC 3330 - 5 (STM & WM)

Question 1

Short-term memory

Answer 1

-stores small amounts of info for a short period of time

-part of working memory

Question 2

Working memory

Answer 2

-temporary storage and manipulation of information to allow for reasoning, learning, and comprehension

Question 3

How is short-term memory assayed?

Answer 3

digit span

Question 4

How is working memory assayed?

Answer 4

working memory span

Question 5

Primacy effect (STM)

Answer 5

better memory for first list items

Question 6

Recency effect (STM)

Answer 6

better memory for last list items

Question 7

Suffix effect (STM)

Answer 7

extra info at the end reduces the recency effect

Question 8

The Peterson Task and Trace Decay found that:

Answer 8

short-term memory decays over time (eg. simple trace decay)

Question 9

Read up on Peterson Task

Answer 9

slides 6-7

Question 10

Working memory complex span tests involve both:

Answer 10

retention and processing

Question 11

Working memory is retained in limited capacity short term stores in the

Answer 11

posterior brain regions (eg. parietal lobes)

Question 12

In working memory, the PFC:

Answer 12

-refreshes information in stores (rehearsal)

-manipulating info

Question 13

Perception and long-term storage is in _______ regions

Answer 13

non-frontal

Question 14

Short-term maintenance and manipulation are in the ________ regions

Answer 14

frontal

Question 15

Lexicality

Answer 15

words remembered better than non-words (component of LTM needed to support WM)

Question 16

Operations of he visuo-spatial sketchpad include:

Answer 16

-mental scanning

-mental rotation

-boundary extension

-dynamic memory

Question 17

Visuo-spatial sketchpad

Answer 17

influence of visual/spatial factors on memory span

Question 18

Mental scanning

Answer 18

time needed to mentally scan a spatial distance increases with size of distance

Question 19

Mental rotation

Answer 19

time needed to recognize an object is a function of the degree of rotation needed

Question 20

Boundary extension

Answer 20

visual information beyond the field of view is filled in suggesting more of a scene was viewed than is actually present
