Document Summary
Simultaneous, in multiple areas of the brain: many simple, highly interconnected units (neurons) Implausible to view units as memories, associations as connections between units. A memory is a pattern of activation across many units: memories are stored in the connections between units. A memory is not stored in any one spot. Distributed memory retrieval: when a distributed pattern of activation is recalled, will tend to fill in gaps in the original pattern. If you have a partly activated pattern, it"ll fill in the rest of the pattern (straightforward analysis) If pattern is cue and response, and you present the cue, then you memory will fill in the response as the rest of the pattern. If original pattern = cue + response, presenting cue will activate the response. Linear associator is simple system that has these properties: provides an illustration of distributed memory mechanics.
