Document Summary

Concepts from the same category are strongly connected. Semantic memory: the permanent memory store of general world knowledge. A network: a hierarchical, interrelated set of concepts. Nodes: a point or location in the semantic space (a concept) Spreading activation: the mental activity of accessing and retrieving information from this network. Activating a concept will result in related concepts also becoming activated representation knowledge. Two nodes and their direct pathway represent a proposition: a relationship between two concepts (birds have feathers) Sentence verification task: simple sentences are presented for the subject"s yes/no decision. Prediction from collins and quillian model: the further two concepts are removed from each other in the network, the longer the reaction time. Typicality effects, typicality: the degree to which items are viewed as typical, central members of a category. The collins and quillian model could be updated by making less typical isa pathways longer.
