Document Summary
Motor cortex, language area, ect: the recall of a memory effectively reactivates the neural patters generated during the original encoding. Sensory memory- experimental study: sperling (1960) presented letter arrays. Iconic memory is short- lived and fades rapidly: loss of information over time in memory is called decay. Short- term or working memory: has a limited capacity less than iconic memory, can be increased by chunking, can only hold 7+2 chunks (multiple digits) or bits (1 digit) information, has a limited duration. Information can decay in seconds- better retention possible by rehearsal (repeating items: experimental study: prevent rehearsal by backward counting, coding can be acoustic, visual or semantic. Long- term memory: consists of several distinct subtypes. Cognitive model: without use of rehearsal, lt memory decays rapidly over 1st few years, some residual memory stays for many years, after that slight loss of memory occurs over the years.
