Abstract

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. This model consists of two functions, one called "activation" and the other "availability", and is tested by means of simulation of the responses in the context of different stimulus patterns. The results of the simulation show a good qualitative fit to the empirical results on the phenomena of habituation, including dishabituation. In addition, the model is suitable for inclusion in associative models that reproduce classical conditioning, which will make it possible in the future to incorporate into these in a simple way the influence that the habituation of each stimulus may have on its association with other stimuli.
