O Working Memory Model - A01 and AO3 O 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: Phonological loop Central executive O O O Episodic buffer Long-term knowledge systems Central executive o Supervisory system for the overall control and running of the memory system. Controls attentional mechanisms. Phonological Loop O One of the components of the slave systems. o Stores a limited number of speech-based sounds for brief periods of time. Consists of two subcomponents: the phonological store (stores acoustic items for a short period of time) and the articulatory control system (allows for subvocal rehearsal/repetition. It is necessary for language acquisition (the process by which humans acquire the capacity to comprehend a language). Visuospatial sketch pad Has limited capacity. Involved in problem solving and decision making. O Monitors and co-ordinates the operation of the two slave systems. Visuo-spatial Sketchpad O Stores visual and spatial information. O Responsible for setting up and manipulating mental images. Has limited capacity. Two subcomponents: inner scribe (deals with the spatial relationship between objects so visualising shapes in our "mind's eye") and the visual cache (stores visual information like form, shape and colour of an object. O O Strengths: O Episodic Buffer o o O Baddeley and Hitch (1976) Aim: To investigate is different parts of the working memory can be used at...

the same time. Method: in condition 1 participants were required to repeat a list of numbers (acoustic and visual). In condition 2 they had to answer true or false.- Dual tasks Results: When both tasks required the participants to use their phonological loop their performance was impaired. However when one task used the phonological loop and the other the visuo-spatial sketchpad, then their performance was significantly better. Evaluation O It's a temporary store that integrates information from other components. Added in by Baddeley (2000). Acts as a "back up" store which communicates with both the LTM and the components of WMM. Research support from dual- task studies, which have found that participants perform better when using different components of the WMM. O WMM is a more plausible model than the MSM as it explains STM terms of both temporary storage and active processing. o Supported by cases studies e.g. Patient KF PET scans have shown that different areas of the brain are active while completing visual and verbal tasks. Weaknesses: o It is only concerned with the STM and doesn't explain the transfer to LTM. O There is very little research investigating the Central Executive and how it works, thus cant be used to explain any experimental results. O Lieberman (1980)- criticises WMM by pointing out that bling people have spatial memory (can remember where thing are and not bump into them) though never having had any visual information.
