Memory- Working Memory Model

Question 1

WMM-Baddley 1974

Central executive? 🔺… 👦🏿👦🏿👦🏿

Answer 1

CE- monitors and coordinate all other mental functions 🔺👦🏿👦🏿👦🏿 has 3 slave systems

Question 2

Phonological Loop- 🔊🔊… Preserve 1️⃣2️⃣3️⃣
↪️articulatory process- 🆎👂🏽 & 👀… 🔄🔄= MR

↪️phonological store- 👊🏾🆎👂🏽

Answer 2

Phonological loop-deals with auditory information and preserved order of info
↪️articulatory process- words you hear and see (👂🏽👀) (🔄silently repeated like an inner voice= maintanece rehearsal)

↪️phonological store- holds word you hear 👊🏾👂🏽

Question 3

Visio-spatial sketch pad (Logie 1995)

Two divisions-

VC👀

IS 🖊

Answer 3

Visual cache-info about visual items 👀🌸

Inner scribe- stores the arrangement of objects in a visual field 🖊

Question 4

Episodic Buffer (LTM RELATED) 
Baddley (2000) adds it

Answer 4

• extra storage system
• integrates info from the CE, PL and VSS
• time sequencing= mental episode of what is being experienced

Question 5

Evaluation

+Dual task performance
↪️hitch and Baddely, 1976

What did task 1 consist of?

What did task 2 consist of?

Results and what it demonstrates?

Answer 5

Task 1- occupy CE >statement given and shown letters then asked whether statements were true of false

Task 2- occupy articulatory loop (asked to say “the” repeatedly) or involved both CE and the AL (asked to say random digits)

Result- Task 1 slower when Task 2 included both Cent.Ex and Artic Loop
↪️demonstrates dual task performance effects and that the Cent ex is part of the WMM

Question 6

Evaluation-

Limitations

CE Too vague

Eslinger and Damasio (1985) studied EVR who had his cerebral Tumour removed.

How did he perform on tests which required reasoning?

How did he perform on tests which required decision-making

Answer 6

Performed well on tests which required reasoning = Suggestd CE was intact

He had poor-decision making skills = suggests CE was not wholly intact

CE is more complex than assumed

Question 7

Limitation-
Evidence from brain damaged Ppts

Most evidence for WMM came from individuals who suffers serious brain damage

One thing which maybe attributed to behaviour changes

Other difficulties which can reduce performance

Answer 7

Traumatic nature of brain injury which can make a person perform worse on certain tasks

Difficulties such as paying attention =underperformance on certain tasks
