Resumen
The role of schedule-induced behaviors (also known as adjunctive) in temporal estimation tasks is yet to be fully understood. 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.
