1. Topic 2 – Cognitive Psychology Lesson four – Working memory model 1

2. Working memory model 1 LO: describe the main components in the working memory model. LO: describe the main components in the working memory model.

3. Recap  Information processing  Encoding  Storage  Retrieval  Capacity  Duration  Sensory register  Short term store  Long term store

4. Work this out in your heads in silence... 17 + 29 + 30 = 43 + 12 + 23 = What process do you use to work these out? ◦Temp storage of the numbers whilst retrieving the knowledge needed to perform the calculation ◦Likely that you two calculations are made (i.e. 29+30 & 59+17) ◦Solution would need to be stored temporarily before the final sum ◦Process performed by the working memory 76 78

5. Working memory model (WMM) Baddeley and Hitch (1974)  Expands on the MSM and the over-simplistic representation of the MSM and the short term memory store  Working memory – what does this mean?  All the information we are currently working on is held there

6. When do we use working memory? Working memory is fragile…. What happens if you are trying to remember a number and someone starts talking to you? ◦Distractions What if you are trying to remember a very long list? ◦Overload What if the mental calculation is very long and complicated? ◦Overwork

7. Drawing task  Pairs  One is the reporter (can see the diagram for 30 seconds)  Other member has to draw this from the description. Reporter cannot draw!

8. Central Executive: Phonological loop: Visuo-spatial pad: Components of the working memory

9. The Working Memory Model (Baddeley & Hitch, 1974)

10. Research task Central Executive: Directs attention to particular tasks. It controls the other systems by determining how resources will be allocated. (Think a control tower at an airport.) Phonological loop: Controls auditory information. Further subdivided into the phonological store (inner ear) and articulatory process (inner voice). Visuo-spatial pad: Processes visual and spatial information (how things look and where they are).
