A first order approximation of satiation time: (IRT)2/Rt

Habituation, satiation, adaptation, and boredom are a few of the words used to label the behavioral consequences of a fundamental operation: repeated and protracted presentation of a stimulus. The cumulative measure of the response associated with that stimulus is expected to display an inflection at some time Ti after which the slope approaches zero. Ti can be estimated by dividing the square of the interresponse time (IRT)2 by the duration of the response associated with reinforcement (Rt), where Rt is expressed in the nearest whole temporal unit of interresponse time. Calculated TiS for habituation to the same sexual, aggressive, or social stimuli are compatible with general observation.
