Psychology essay working memory model

Memory is the term given to the structures and processes involved in the storage and subsequent retrieval of information. Memory is essential to all our lives. Without a memory of the past, we cannot operate in the present or think about the future. We would not be able to remember what we did yesterday, what we have done today or what we plan to do tomorrow.

Psychology essay working memory model

Psychology 4a link A It has been developed to directly challenge the concept of a single unitary store for short-term memories. The working memory model is based upon the findings of the dual-task study and suggests that there are four separate components to our working memory STM.

It also controls attention and plays a major role in planning and synthesizing information, not only from the subsidiary systems but also from LTM.

It is flexible and can process information from any modality, although it does have a limited storage capacity and so can attend to a limited number if things at one time.

Another part of the working memory model is the phonological loop, it stores a limited number of speech-based sounds for brief periods. It is thought to consist of two components - the phonological store inner ear that allows acoustically coded items to be stored for a brief period and the articulatory control process the inner voice that allows sub-vocal repetition of the items stored in the phonological store.

Another important component is the visuo-spatial scratch pad; it stores visual and spatial information and can be thought of as an inner eye. It is responsible for setting up and manipulating mental images.

Like the phonological loop, it has limited capacity but the limits of the two systems are independent.

In other words, it is possible, for example, to rehearse a set of digits in the phonological loop while simultaneously making decisions about the spatial layout of a set of letters in the visual spatial scratchpad.

Finally in Baddeley proposed an additional component, the episodic buffer. One strength of the WMM is that there is evidence to support the phonological loop. Baddeley word length effect short words easier to recall than long. Prevention from being able to rehearse words by repeating an irrelevant sound.

The word length effect was lost as articulatory suppression fills the phonological loop. A second strength of the WMM is that there is evidence to support the visuo-spatial scratch pad. Baddeley PPts hold a pointer with a moving spot of light whilst visualising the block capital letter F.

Tracking and letter imagery tasks were competing for the limited resources of the visuo-spatial scratch pad. Where as the tracking and verbal tasks use separate components. One weakness of the working memory model is that the Central Executive is difficult to quantify.

Little research has been done to understand the central executive. Richardson Problems specifying the precise function of the central executive. It cannot be falsified. A second weakness of the WMM is that the research is lab based. However, the model could be argued to have mundane realism since the tasks given to participants COULD potentially represent experienced in daily life e.Baddeley's working memory model explained for AQA Psychology A level revision with a 12 mark essay answer by an A* Psychology A level Student.
