Evaluate two models or theories of one cognitive process with reference to research studies.

This article evaluates two models of working memory: the Multi-Store Model and Baddeley and Hitch's Working Model of Memory. It discusses the main arguments of the Working Model and provides evidence from research studies to support its claims.

  1. Evaluate two models or theories of one cognitive process with reference to research studies.

  2. Model 2: The Working Model of MemoryBaddeley and Hitch 1974 • Main argument was that Short Term Memory in the Multi-Store Model was much too simple (too passive). • They replaced STM with something they called Working Memory.

  3. The Working Model of MemoryBaddeley and Hitch 1974 • Working Memory does not just sit there and take information. • Instead of all information going into one single store, there are different systems for different types of information.

  4. The Working Model of MemoryBaddeley and Hitch 1974 • The Working Memory consisted of three main sections with a fourth added in 2000 by Baddeley.

  5. The Working Model of MemoryBaddeley and Hitch 1974 The Central Executive • Drives the whole system (e.g. the boss of working memory) and allocates data to the subsystems . • Like the Fat Controller from Thomas the Tank Engine. • Sends info to the other “slave” systems.

  6. The Working Model of MemoryBaddeley and Hitch 1974 The Phonological Loop • Handles verbal and auditory information. • Divided into two parts • Articulatory control process (inner voice) Linked to speech production. Used to rehearse and store verbal information from the phonological store. • Phonological Store (inner ear) Linked to speech perception Holds information in speech-based form (i.e. spoken words) for 1-2 seconds.

  7. The Working Model of MemoryBaddeley and Hitch 1974 The Visuo-Spatial Sketch Pad • (inner eye) • This is believed to hold visual information. • The eyes are used to store and manipulate visual and spatial information such as remembering colors or shapes. • Also used for navigation.

  8. The Working Model of MemoryBaddeley and Hitch 1974

  9. Evidence that the WMM is the real deal. • The WMM helps explain real life problems. Like why we cannot process written and verbal information at the same time. • PET scans show evidence of separate components of STM as different areas are activated during different tasks. • KF Case Study

  10. A study that proved the Working Model of MemoryQuinn and McConnel (1996) • They asked participants to memorize a list of words by using either imagery or rehearsal. • The task was performed on its own or with a concurrent visual noise (changing patterns of dots) or a concurrent verbal noise (speech in a foreign language).

  11. Quinn and McConnel (1996) • The results showed that learning by imagery was not affected by a concurrent verbal task • but was disturbed by a concurrent visual task. • The opposite was found in the rehearsal condition.

  12. Quinn and McConnel (1996) • This indicates that imagery processing uses the Visuo-Spatial Sketch Pad whereas verbal processing uses the Phonological Loop. • If the two tasks used the same component, performance deteriorated. • The study this lends support to different “slave” systems of memory.
