Document Summary
Stm retrieval is either immediate and automatic or does not occur. Ltm retrieval may be considerably slower and more groping. Implicit memories, although they involve things that one knows, cannot be remembered and verbalized. Two kinds of declarative memory: semantic and episodic. Semantic memory - general, stable, abstract facts and principles. Episodic memory - private knowledge that is temporal in nature and tied to specific personal events. Sensory memory - momentary sensory impression; lasts a fraction of a second; unconscious. Memory as a sequential record we choose to retrieve. Frequently make use of schema or node models. A node/ schema is a metaphor for an idea representation. Node theory suggests that we remember abstractions, gists. A multilevel classification system based on common properties among items. An organized cluster of information about an object or event. The engram - trace changes in the brain. Learned a maze & then had parts of the rat brain excised.
