Document Summary

Stm/wm is mostly acoustic, since we rely so much on phonological buffer, and it"s parti(cid:272)ularly easy i(cid:374)for(cid:373)atio(cid:374) to keep a(cid:272)ti(cid:448)e (cid:271)y refreshi(cid:374)g/rehearsi(cid:374)g. Decay (usually lost by 30 sec unless rehearsed) Then: count backwards from 831 by 3s. Then: recall chj when light goes on. Visuospatial sketchpad - visual/spatial info, including images. Semantic (related to language/logic) relatedness & interference in stm. Semantic similarity leads to proactive interference (pi) Cha(cid:374)gi(cid:374)g the (cid:272)ategory to (cid:862)jo(cid:271)s(cid:863) led to release fro(cid:373) pi. So information in stm is not encoded just acoustically or just visuo-spatially, but also semantically. Loss from short-term memory occurs because of both decay and interference. Whe(cid:374) i say (cid:862)go,(cid:863) (cid:449)rite do(cid:449)(cid:374) as (cid:373)a(cid:374)y of the ite(cid:373)s as you (cid:272)a(cid:374). People tend to be best at the first and last items. Primacy effect - remember first things first; privileged rehearsal, better ltm encoding. Recency effect - remember most recent things first; stm contribution. Elaborative rehearsal (meaningful processing) usually better than maintenance (surface) rehearsal.
