research into how different slave systems work WMM

who conducted as study looking at if the visuospatial scratch pad was a separate store from other slave systems

Robbins

describe the sample

20 male chess players

describe robbins method

from 2 unis had to memorise the location of chess pieces on a chess board. They saw them for 10s and then had to recreate them on another board. There were 3 conditions which used different slave systems.

what were the 3 conditions in robbins study

1. the condition using the articulatory system. In this they had to repeat the word the over and over again. This requires the use of the articulatory system in the phonological loop.

2. the visuospatial blocking condition. In this they had to press number of on a calculator with there other hand. like the chess task this requires the visuospatial scratch pad.

3. the central executive blocking condition in which ps had to say random letters on a beat.

what were the conclusion for robbins task

1. the articulatory blocking task had no impact as theses are separate store

2. the visuospatial blocking task had a large impact as there the same store and it cant do 2 things at once

3. the central executive task also had a large impact as it controls slave systems

who investigated the aim of dual task on memory

Baddeley and hitch

describe the method Baddeley and hitch used

ps had to perform a reasoning task and recite aloud 6 digest

results of Baddeley and hitches study

ps made few errors however were slightly slower

conclusions of Baddeley and hitches study

STM is made up of multiple components

who investigates the role of/ duration of the phonological loop and articulatory system

Baddeley

method of baddleye’s study

ps either had to remember words of one syllable or polysyllabic

results of baddleys’s study

better recall of shorter words

conclusion of baddleys’s study

suggest the phonological loop holds the amount of info you can say in 1.5-2 s
