PSY270H5 Lecture Notes - Lecture 6: Retrograde Amnesia, Doorbell, Indirect Tests Of Memory
Document Summary
From the previous lecture: a(cid:374)ythi(cid:374)g , modal model of memory. Atkinson and shiffrin"s modal model of memory (1968) Large capacity, decays quickly over time, susceptible to interference. Limited capacity, robust against decay + interference so long as actively stored. Massive capacity, inactive (held inactively) and durable storage (especially compared to sensory mem: double dissociation. -> reverse of each other = double dissociation. These 2 things we are talking about are independent. If just h. m. , this would be a single dissociation. Wait a (cid:373)i(cid:374)ute ho(cid:449) (cid:449)as k. f. a(cid:271)le to fo(cid:396)(cid:373) ltm (cid:449)hile his sho(cid:396)t-term mem was impaired: the capacity of visuo-spatial sketchpad (or visual short-term or working memory) Quickly presented rows of letters + asked ss to report them all (whole report) - diffi(cid:272)ult . Amount of info that are stored in durable enough format to report seems limited: limited capacity of short-term memory.
