PSYCH 140M Lecture Notes - Lecture 1: Supramarginal Gyrus, Neuroimaging, Sketchpad
Document Summary
Added to model of working memory in 2000 (third slave system) to account for working memory"s ability to use ltm. Storage system that links/integrates visual, spatial, and verbal info from working memory into a single complex structure or episode . Can also pull in visual, spatial, verbal, and semantic information from. Added to model as a type of general storage, since none of the other three components can combine several kinds of information . Baddeley"s most recent model (2000) also adds links between phonological loop and long-term language memory, and between visuospatial sketchpad and long-term visual/spatial information to account for acquisition of language and encoding of visual/spatial information into. Left supramarginal gyrus (an area between parietal/temporal lobes of left hemisphere) appears to be responsible for phonological storage. Broca"s area (long known to be involved in speech production) appears to be linked to subvocal rehearsal. Visuo-spatial memory resulted in activation in a series of areas of the right.
