One study was conducted to evaluate the effects of manipulating the values of P on performance under temporal defined schedules. It was used 6 experimentally naive albino rats that were divided into two groups. Each group was exposed to a temporal defined schedule with different cycle length. Group 1 was T = 30 s. and Group 2 was T = 120 s. Each group was exposed to four distinct experimental phases. The parameter P was manipulated between phases with the values of 1.0, 0.5 and 0.1. The first three phases the subintervals ∂t and Δt were signaled differentially. During the phase fourth (redetermination), signaling was eliminated in both subintervals. The results suggest that the T-cycle length determines the response patterns. In addition, differences were observed in temporal properties of effective and ineffective responses under signaling and no signaling conditions. The results were analyzed in terms of type of the behavioral adjustment to occurring contingencies featured into temporal defined schedules. We suggest that this procedure represent a relevant methodological tool for analyzing the contextual and supplementary functions suggested by Ribes and Lopez (1985).
