Abstract

In the context of a medium-term study designed to integrate the simulation of different types and processes of learning—such as classical, operant, and some cognitive types—one must start with other more elementary ones that are facilitators of the more complex types and processes. Of special interest is habituation, owing to the filtering out of irrelevant stimuli, which means that the simulated agent does not have to respond to them. This paper presents two difference functions constructed to computationally simulate the characteristics that define habituation. The behavior of these functions is described, as are differences arising from stimulus intensity and interstimulus intervals. Results are compared with existing empirical data.

En el contexto de un proyecto a medio plazo que pretende integrar la simulación de diferentes tipos y procesos de aprendizaje —como el clásico, operante y algunos de tipo cognoscitivo— es fundamental comenzar por otros más elementales facilitadores de los más complejos. Interesa especialmente la habituación debido al filtraje que realiza de los estímulos irrelevantes, evitando al agente simulado responder a ellos. El presente trabajo presenta dos funciones en diferencias construidas para simular computacionalmente las características definitorias de la habituación. Se describe el comportamiento de tales funciones y sus variaciones según la intensidad de los estímulos presentados y el intervalo entre ellos, evaluándose su ajuste a datos empíricos existentes.
