Restriction in the availability of the reinforcer and in the Time Between Responses in a Herrnstein sort concurrent reinforcement scheme

Abstract

A wistar rat was used to evaluate the effects of concurrent implementation of restricted programs on reinforcer delivery and time between responses in a Herrnstein-type program. The study consisted of three experimental phases. In the first phase, an IF10 ”was implemented regardless of the lever pressed by the experimental subject. In the second phase, a time-restricted RDA was used for the 10 "and 5" non-reinforcement reinforcement. For the third phase, both programs were implemented concurrently with the restriction in force in the previous phase, with a DCA of 5 ”. It was found that the execution in the programs depends on the time between reinforcers, in addition to presenting a lower response rate, longer TERs and a smaller number of reinforcers obtained in the concurrent phase, in relation to the isolated situation.
