Current theories suggest there may be two processes responsible for the development of behavioral patterns displayed by organisms and quantitative timing measures within an interreinforcement interval (IRI): induction and response-reinforcer proximity. Previous studies on the issue have failed to demonstrate the scalar property in schedule-induced behaviors, arguing that its absence was due to the lack of an explicit response-reinforcer contingency. To test this hypothesis, a conjunctive schedule of food reinforcement was arranged so that the development of schedule-induced drinking (SID) occurred under stricter control than mere contiguity. Rats were divided into three groups, depending on the value of the fixed-time (FT) schedule used; and all were exposed to a conjunctive FT (15-, 30- or 60-s) fixed-ratio 10 schedule. Preliminary results show that the scalar property is not properly manifested; however, a more comprehensive data analysis on timing measures such as time of transition and last lick do point to a certain scalarity of induced behaviors. Perhaps key to these results are the high variability encountered in FT-60 group, which allows for more proper inter-group comparisons that do show scalarity of SID in terms of duration but not rate. Theoretical implications of these results are discussed.enAtribución-NoComercial-SinDerivadas 4.0 Internacionalinfo:eu-repo/semantics/openAccesstesis de maestríaschedule-induced behaviorstimingscalar propertyinductionreinforcement
