Transcript Evaluation of the Working Memory Model

Shallice & Warrington (1970) Case Study of KF  KF had a bike accident  LTM normal functioning  STM damaged

 KF’S STM forgetting was worse for auditory information (sound) than for visual information.

 He experienced difficulty in letters (ABC) and digits (123)  This indicates KF’s brain damage was restricted to the phonological loop

Trojano & Grossi (1995) Case Study of SC  Had good learning abilities with the exception of being unable to learn word pairs that were presented out loud  Suggests damage to phonological loop

Farah et al (1998) Case Study of LH  Road accident caused brain damage  Performed better on spatial tasks than visual imagery tasks  Suggests separate visual and spatial systems

 The WMM emphasises process more than the MSM and presents a more detailed understanding of STM

 Produces testable predictions which is important for the scientific process

 The working memory model is restricted to STM and has nothing to say about LTM

 Plenty of research support for different stores and dual-task performance

 Evidence from brain-damaged patients may not be reliable because it concerns unique cases often involving traumatic experiences – cannot make comparisons as it is not sure whether changes in behaviour are caused by the damage

 Central executive is vaguely defined and doesn’t really explain anything and it also may consist of separate components – what is it and is it needed?

 Sternberg (2006) – the working memory model is probably the most widely accepted and used model today
