Working Memory Model - AO1 and AO3
• Developed by Baddeley and Hitch in 1974.
• Challenged the Multi-Store model of memory due to stating that there isn’t a unitary
store of STM but multiple ones.
• It is based on dual-task studies (where you perform two different tasks at the same
time.)
• WMM is a multi-component STM system:
Central executive
o Supervisory system for the overall
control and running of the memory
system.
o Controls attentional mechanisms.
o Has limited capacity.
o Involved in problem solving and decision
making.
o Monitors and co-ordinates the operation
of the two slave systems.
