Document Summary
Long-term memory: episodic episodes of one"s life; encoding (how things get into long-term memory in first place), retrieval;; semantic storage. History: herman ebbinghaus on memory (1885) during time when introspection used to understand mind. Experimental control through: to-be-remembered stimuli no prior experience with it, meaningless (no semantic associations), i. e. nonsense syllables (consonant-vowel-consonant, i. e. associations), i. e. nonsense syllables (consonant-vowel-consonant, i. e. kag) Independent variables = retention interval (long = bad for memory, i. e. do all studying early and set it aside till exam), list length (# of nonsense syllables), extended practice (over- learning), serial order. Extended practice = after learning list until 2 perfect recitals, rehearsed list 30 more times. Using 24hr ri, savings in relearning the over-learned list = 64% vs. 34% for normal learning serial order = strength of association between adjacent items on list. Direction of associations = forward and backward i. e. (1) mev, (2) gor, (3) dux forward = would presenting mev evoke.
