Document Summary
Procedural: mems of how to do something; implicit mems; habit learning; devs. gradually. Diff. b/w short and long=capacity and decay over time: capacity long-term=vast, hard-to-measure short-term=limited chunking=grouping items into meaningful sequences/clusters. Decay over time: fades rapidly; > meaningful material=ppl store > info quickly. Brain representation decays: protein that brain makes after experience that weakens memory trace to avoid permanently storing unimportant info confusing info. Memory depends on changes in synapses spread out over huge pop. of cells consolidate=converting short-term memory into long-term mem: problem: how long info remains in short-term is bad predictor of whether it becomes long-term. Mind wandering on easy task: good working mem. =ability to shift attn. as needed among diff. tasks module 7. 1. Hermann ebbinghaus: german psychologist taught new material knew exactly what someone had learned and when: measured memory after delays; measured how much longer it took to memorize longer lists.
