WMM - Working Memory Model
Central executive - has a small storage capacity for allocating memories to the right slave systems for processing
Phonological loop - the phonological store "inner ear" and articulatory process "inner voice" remembers speech and sound and repeats any input to stop it form decaying
Visuo spatial sketchpad - the visual cache hold information about for, and colour and the inner scribe can create mental images in your "minds eye"
episodic buffer - temporary storage and helps memories move between the STM and LTM
Evaluation of WMM
Phonological loop - Baddeley et al. (1975) showed that people have more difficulty remembering long than short words presumably because the phonological loop only holds abotu 2 seconds worth of information.
Brain-damadged participants - Shalice and Warrington (1970) studied "KF" whose LTM was intact and in STM he could not remember verbal material suggesting only his phonological loop was affected
Evaluation of WMM cont.
Strengths - The model makes predicitons that can be tested empirically and thus permits the model to be supported or refuted
it offers a further improvement of the MSM which suggested that memory was not only one store but many, the WMM distinguishes these stores
Weaknesses - some of the components are not satisfactorally explained for some components it is unclear how they could be tested e.g central executive
The WMM does not talk about the LTM
