Week 5 Working Memory

Question 1

Who is Alan Baddeley

Answer 1

He created the first working memory theory
Model states: that it actively works to hold info to work or perform task

Question 2

Working memory

Answer 2

A limited capacity storage system that is concerned with the manipulation of information occurring during complex cognitions

Question 3

Phonological loop

Answer 3

Two components that hold verbal and auditory information

Phonological store: holds info for seconds

Articulatory rehearsal process: responsible for rehearsal items in phonological store

Question 4

Visuospatial sketchpad

Answer 4

Holds visual and spatial information
- used for forming images in mind

Question 5

Central executive

Answer 5

Pulls information from LTM and coordinates activity of phonological loop and visuospatial sketch pad “attention controller”

Question 6

Episodic buffer

Answer 6

Can store info (extra capacity) and is connected to LTM, making interchange between working memory and LTM

Question 7

Testing working memory -Logie 1990

Answer 7

Dual task: presenting primary/ secondary phonological or visuospatial task simultaneously.
Conclusion: different stores process different types of information.

Operation span test: present a letter then math problem then letter then have individual recall letters in order.
Conclusion: demonstrates high or low span of phonological similarity effect (confusion of letters/words that sound similar)

Question 8

Testing working memory -Logie 1990

Answer 8

Word length effect: occurs when memory for a short list of words is better than a long list of words

Articulatory suppression: repetition of irrelevant sounds that interferes with rehearsal and decreases memory
