Document Summary
Introduce different components of the classic multi-store model of memory. Today"s goal: describe the structure and processing of stm, describe ways of measuring wm capacity. Function: how does it work: serial vs. Or parallel: modular vs. domain general processing, connection between memory and attention. In this class we focus more on modular view. If you don"t pay attention to something, it is less likely you"ll remember it later. Short-term memory (stm: a limited capacity store that holds information for a relatively brief period. Without rehearsal the duration of stm is only a few seconds (~20-30 s) When we can rehearse, duration can be longer. Rehearsal keeps information in stm and helps pass it on to long-term memory. George miller proposed the magical number 7 2 is the capacity of stm: each slot" can hold one item, we possibly hold information in the 7 +/- 2 slots. It is easier to recall because acronyms are meaningful units in ltm.
