Outline and evaluate the working memory model

Extracts from this document...

Introduction

´╗┐Outline and evaluate the working memory model. The working memory model (WMM), proposed by Baddeley and Hitch, is a functional model which focuses on the components of short- term memory. The main component is the central executive (CE), which directs attention to information and determine how information will be allocated. There are 3 slave systems under the CE which are specialised to carry out a particular task and manipulate and analyse information. The slave systems are the phonological loop which deals with auditory information. ...read more.

Middle

It integrates information from the CE and all the other slave systems. One of the strengths of the working memory model is that there is evidence for the existence of the key components of this model of memory. For example, Baddeley et al. demonstrated the existence of the visuo-spatial sketchpad. In the study the participants had to track a moving light with a pointer whilst visualising the letter F (task 1) or doing a verbal task (Task 2). ...read more.

Conclusion

Park et al, reviewed a number of cases studied and concluded that patients with schizophrenia had problems with their working memory. One major weakness of the working memory model is that it does not give adequate explanation for the CE. The model suggests that the central executive allocates information which seems to be the same as attention. Many believe it must sub-divided into different components rather than being an unitary component. The case study of EVR suggests that the central executive must be sub divided. EVR had a cerebral tumour removed after which he performed well on tests requiring reasoning, however his decision making skills were poor which suggested that the CE was not wholly intact. ...read more.

  1. Outline and evaluate the working memory model

    The central executive also has no storage capacity. However the episodic buffer is an extra storage system in which information from the central executive, the phonological loop, the visuo-spatial sketchpad and also the LTM is integrated. There is a considerable amount of supporting evidence for the W.M.M.

  2. Discuss the Main Treatments for Schizophrenia

    This analysis found that two of the new drugs tested were only ?slightly? more effective that conventional antipsychotics, while the other two were no more effective. Drugs may block the search for psychological solutions- ROSS & READ (2004) argue that being prescribed medication reinforces the view that there is ?something wrong with you?.
