Working Memory Model Baddely and Hitch (1974)

1. Central Executive: decides what slave system must be used to process information

   • Phonological Loop: processes spoken and written information
   • Visuo-spatial sketchpad: processes visual information

2. Kosslyn and Swartz (1981): their eyes moved to the area in the head they were trying to remember, and the longer they looked down the boat they remembered less of it.

3. Evaluation

   • Pros: its good as it tells us how the slave systems can be involved in performing a specific task. more plausible than the MSM as it shows the processing involved. doesnt over emphasise the importance of rehearsal. suggests practical applications
   • Cons: only deals with STM. doesnt explain changes in processing. not clear how the central executive works as there is little research to prove its existence. a lot of the research is lab based and so is not ecologically valid and hard to generalise to everyday memory
