|Descripción:||This study assessed the effects of signal duration and t d duration on response acquisition of lever-pressing by rats. Thirty naïve male Wistar rats were exposed to one of ten different 32-s temporally defined schedules of delayed, signaled reinforcement. Reinforcement cycles were divided into two temporal time windows, t d and t delta; responses emitted during t d produced reinforcement at the end of the cycle; responses emitted during t delta had no programmed consequences. t d was located at the beginning of the reinforcement cycle and was fixed at one of two different values (4-s or 8-s). The first response emitted during td produced an audible tone of different duration; tone duration was varied across groups Results showed variability, however evidence of response acquisition was more apparent with the long t d duration and with the longer signals. This effect could probably be attributed to the interaction of Pavlovian, and mnemic variables with stimulus discrimination processes.|
