WMM STRENGTH- Baddeley (1975)
Pts memory span for one-syllable words = greater than for polysyllabic works, suggesting articularly loop is only able to hold a certain amount of chunks. Later studies suggest it's the amount of time it takes for a person to say a word instead.

WMM STRENGTH- KF Case Study
KF damaged his STM, being mainly verbal memory + his visual memory being fine. Supports phonological loop and VSSP.

WMM STRENGTH- DeGroot (2006)
Looked @ expert chess players. No Better @ recalling chess piece had been randomly placed that non-players. Long-term store = helps interpret info in the Short Term Working memory, as they could recall where they were in the correct position.

WMM STRENGTH- Klauer and Zhao (2004)
Found that visual memory tasks were more disrupted by visual interference + spatial tasks more disrupted by spatial interference, offering evidence for separate components to the VSSP.
4 of 7
WMM WEAKNESS of the original model
It didn't explain evidence from verbal span experiments that verbal and visual encoding could be combined, and couldn't explain how the subcomponents could interface with eachother or LTM. This was rectified with the addition of the episodic buffer.
5 of 7
WMM WEAKNESS of store imbalances
Limitation = WMM's inability to explain why we can store short word sequences in phonological loop, but longer sentences. Could be explained by being bound together by meaning and grammar, but doesn't explain phonological loop's capacity.
6 of 7
WMM WEAKNESS of the Central Executive (bit of weakness of falsifiability in there)
Functions of the Central Executive = vague and difficult to test. Baddeley claims it has limited capacity, but how this can be measured is unclear. Also claims it can be divided into subsystems, but these aren't identified.
