Document Summary
Primary memory- william james: a memory system that keeps a small number of items in consciousness, more closely related to working memory than stm. What affects memory span: auditory presentations lead to larger memory span than visual presentations, rhythmic presentation better than non-rhythmic. Chunking- george miller: memory span is determined by the number of chunks you need to recall, not the number of items presented. Hypotheses for paradigm: trace decay- you hear an item, it has a vivid memory representation, but fades over time automatically. Argued that it must be trace decay. Proactive- effects of prior items on recall of subsequent items. Retroactive- effects of subsequent items on recall of previous items. Cannot be retroactive because items are not numbers and cannot interfere with them. Keppel and underwood said it is proactive because if in trial one, there isn"t previously studied material to interfere with the items you"re supposed to recall.
