Working Memory Model
Phonological loop
-

Phonological similarity (Baddely, 1966)
-
Irrelevant speech effect

Visuospatial sketchpad
Image scanning
people scan visual imagery in VSS. learn map with 7 locations. move from one location to another. response time increase with distance. (Kosslyn et al. 1978)
Mental rotation (Shepard & Metzler, 1971)
Limitations
Interaction of WM with LTM? e.g. phonological loop has limited store (unrelated words 6) bt ppl can routinely rmbr unrelated words (15016) - chunking (needs interaction with LTM)
-
Episodic buffer
-
limitations:
1) not fully developed or tested
2) natural extension of wm?
3) or catch all for processes not fully understood
