Document Summary

Episodic memory trace includes details about when and where you learned something. Semantic memory works as network (neural networks, have similar properties that neurons are connected in the brain) Individual concepts represented as nodes in a memory network: e. g. birds. Concepts / nodes that are semantically associated are interconnected (associative links: e. g. birds robin and eagle and loon etc, learning is building these associative links, some links are more effective than others at carrying the activation. Degree of semantic relatedness between two concepts is represented by the strength of the interconnection between their nodes: e. g. see more loons and eagles at cottage than robins therefore relationship between loons and eagles is stronger, e. g. Then robins and birds node is a stronger connection. Some concepts are more representative of a category than others therefore take less time to activate (a robin is a bird vs. a peacock is a bird) Both are direct links but peacock would take longer.
