Document Summary

Semantic memory: the ltm component in which general world knowledge is stored: general knowledge about the world that all members of a culture possess. 2. remember the fish attacked the fisher offer a cue to recall: best cue: a shark, not fish. Instantiation: encoding a particular structural node as connected to a particular semantic node: semantic memory intrudes" to influence episodic memory. Schaeffer and wallace similarity in category help yes but hurt no the use of overlap of feature. The collins and quillian model: 2 assumptions, nodes in a network- the structure of semantic memory: i. ii. iii. Network: a structure of info stored in ltm, concepts are represented as nodes that are interconnected by pathways, activation spread from concept to concept along that connection pathway. Node: a point in the ltm representation of knowledge, a concept. Pathway: network in ltm, the connecting link between 2 nodes length of links between concepts= strength of associations.
