Abstract
In this presentation, it was intended to investigate whether Hopfield model would mimic human semantic memory or not. As well-known, connection weights among units in Hopfield model can be interpreted not only as embedded memory traces, but also similarity matrix among features. Also, there are neuropsychological evidences that human performances of concept formation and category judgment are influenced both external stimulus and intrinsic inner memory representation. In this way, several common characteristics can be pointed out between Hopfield model and human semantic memory, it might be worth examining the relationship between Hopfield model and psychological models of concept and category. In order to determine validity of some psychological hypotheses, mathematical considerations were conducted. The contribution of current stimulus and past experiences to concept formation were further discussed.
