Simulation of habituation to simple and multiple stimuli.

Within the psychological literature there are a number of models that reproduce the defining properties of habituation to a single stimulus. However, most of them do not reproduce the phenomenon of dishabituation shown in empirical studies, consisting in the recovery of a stimulus previously habituated upon the appearance of a novel stimulus. The present work offers a model of habituation which, in addition to reproducing the basic properties of habituation to a stimulus, also does so when more than one stimulus is presented, and thus includes the dishabituation phenomenon.
