Document Summary

Explicit memory: episodic memory: memory of your life history- occasions, specific memories, most people have intact memory for the explicit meaning of concepts, but amnesia for the source of the meaning. Explicit memory: semantic memory: explicit knowledge of the meaning of words, facts, ideas, sense of knowing rather than remembering. Hierarchical network models bird, animal + properties: logical hierarchical structure with interconnected (cid:498)nodes(cid:499) e. g. canary, cognitive economy: each concept only stored once, no redundancy, properties stored at highest level of network, spreading activation retrieves meaning. Evaluation of hierarchical model: sentence verification task: measure time to verify sentence, as well as semantic distance between nodes, time to verify was also affected by strength of initial activation and amount of time since initial activation. Parallel distributed processing models of attention, memories are stored particular patterns of activation. Treatment for fears: expose the person to the fear, rewiring the network.
