Document Summary

Short term memory (stm: working memory, material (cid:862)held(cid:863) (cid:271)y rehearsal, no rehearsal= i(cid:374)fo lost forgetti(cid:374)g, shelf-life of 20 seconds, rapidly lost unless we actively do something with it. Decay: material gets old, fades away over time. Sleeping and 8 hours recalling it) if sleeping- going to recall with better accuracy (decay- not interference) for awake- decay and interference this why sleep is very important before an exam- you will remember more: acoustic coding. The max. interfering words are words that sound the same: book, bar, fish these will mess it up. 3 components of stm: phonological loop- auditory, visual-spatial sketchpad- images and spatial, central executive- directs attention, recall, integration (prefrontal cortex) Rehearsal: maintenance- keeps items in stm, active- organizing (making it meaningful) What is memory: ultimately, some biochemical event- changing connections in neurons, the e(cid:374)gra(cid:373) (cid:894)fro(cid:373) pe(cid:374)field(cid:859)s data(cid:895, pe(cid:374)field(cid:859)s data- when you touch cortex, you can remember things, memory is stored in cortex somewhere.
