encode store, and retrieve info

Question 3

Atkinson and shiffrin modal

Answer 3

Question 4

What are controlled processes?

Answer 4

Active processes controlled by a person rehearsal, memorization strategies

Question 5

what is sensory memory

Answer 5

stores info briefly allows other processes to extract input for later use. 1/2 second memory fades quickly

Question 6

Sperling whole report

Answer 6

reported all letters presented for 5 millisecond people got 4-5 right after = Stm

Question 7

Sperling partial report procedure

Answer 7

A cue was indicated to which letter to report people on average got 9 letters = sensory memory

Question 8

Stm

Answer 8

lasts longer than sensory memory 15-30 seconds stores or as long as you keep rehearsing items stores more meaningful info than sensory memory hold between 5-9 items

Question 9

What is chunking

Answer 9

allows us to store more than 1 item more efficiently you combine many items at once

Question 10

Conrad tests

Answer 10

auditory code visually presented a series of letters participants had to recall letters in order. Looked at errors made by sound

Question 11

Posner & keele

Answer 11

presented letters one after another, participants said if the letters were the same or different letters. Visual code took participants longer to answer when the shape was different.

Question 12

Shulman semantic tests

Answer 12

visually presented a list of words. they presented the subjects with a word and asked whether it had been on the list. Participants were asked if the word was on the list. synonym error subjects confused words like talk for speak

Question 13

Problems with the STM as a shelving system 3

Answer 13

1 word lenght longer words are difficult to remember 2 phonological similarity test - list of similar words are more difficult to remember 3 articulatory suppression say something repeatedly while listening to a list of words

Question 14

Phonological loop

Answer 14

takes in auditory messages limited amount of time before it decays forever2-4 seconds subvocal rehearsal repeat to self

Question 15

3 parts for working memory

Answer 15

1 central executive controls everything, 2 phonological loop audio encoding, 3 visual spatial sketch pad visual and spatial info. multiple parts and can not process similar types of info presented at 1 time

Question 16

Serial positon curve 1 normal

Answer 16

If lists of words are read people will remember the first few words and the last few words

Question 17

Serial position curve 2 delay

Answer 17

If there is a distractor at the end there will be no recency effect but primacy still stays

Question 18

Serial position 3 fast counting

Answer 18

No primacy effect but there will still be a recency effect but not primacy effect.

Question 19

2 types of rehearsal

Answer 19

1 Maintenance 2 elaborate

Question 20

word length effect

Answer 20

longer words are harder to remember take longer time to remember

Question 21

phonological similarity effect

Answer 21

list of similar words are more difficult to remember takes more mental processing to distinguish words

Question 22

articulatory suppression

Answer 22

say something repeatedly while listening to the list of words, ex the will interfere with your ability to remember
