PSYC3315 Lecture Notes - Lecture 2: Semantic Dementia, Episodic Memory, Explicit Memory
Document Summary
Memory: means by which we retain & draw on past experiences to use that info in the present, 3 common operations of memory: (i) (ii) Explicit memory: trying to access our memory interpretations, ppl engage in conscious recollection. Tests of explicit memory = direct tests: recall memory. Cued recall: use cue to recall info: eg. Usually better than recall bc retrieval is cue-dependent: semantic vs episodic memory. In old age / dementia, recent episodic memories forgotten first. In semantic dementia, semantic knowledge & old episodic memories forgotten first. Previous learning interferes with later learning: retroactive interference. Later learning interferes with earlier learning: rest periods prevent interference. Implicit memory: use memory representation to guide behavior w/o thinking about it (not conscious, eg. Semantic priming: stem completion i. e. d_g; more likely to say dog instead of dig after recent exposure to cat. Perceptual priming: fragment completion, repeated exposure speeds up processing, can be very long lasting, other forms of implicit memory.
