Baddeley and Hitch Dual Processing Task

Baddeley and Hitch Dual Processing Task

1. If the same component is used to carry out task simultaneously then capacity is limited

2. However if the tasks rely on different components then the task is performed normally

3. Participants performed a reasoning task while simultaneously reciting aloud a list of numbers

4. To remember a list of numbers which requires the phonological loop

5. To complete a sentence verification task this requires the Central Executive

6. The speed of verifying the sentence slowed down there were few errors on either the reasoning task or memory task, providing evidence for more than one store of WMM

7. Can store shorter words in the phonological loop easier than longer words. Word length effect

8. When they were prevented from rehearsing the word length effect disappears

9. This provides strong evidence for the phonological loop
