Topic 2 – Cognitive Psychology Lesson four – Working memory model 1
Working memory model 1 LO: describe the main components in the working memory model. LO: describe the main components in the working memory model.
Recap Information processing Encoding Storage Retrieval Capacity Duration Sensory register Short term store Long term store
Work this out in your heads in silence = = 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 & 59+17) ◦Solution would need to be stored temporarily before the final sum ◦Process performed by the working memory 76 78
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
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
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!

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