چکیده انگلیسی
Pigeons were trained to match 2- and 8-s food samples. The delay on training trials was either 0Â s (group 0sF), 5Â s (group 5sF), or varied between 2 and 8Â s (MÂ =Â 5Â s, group 5sV). Testing at a delay that exceeded the training delay by 15Â s in each group revealed a robust choose-short effect in each group. The same pigeons then reacquired a previously trained matching task involving 2- and 8-s keylight samples. Different comparison stimuli were used on food-sample and keylight-sample trials. The delay on training trials was the same on both food- and keylight-sample trials. Extended-delay testing revealed a robust choose-short effect in all three groups when the durations were conveyed by food presentations, but only group 0sF revealed a choose-short effect when the durations were conveyed by keylight presentations. Hence, training with a nonzero delay, whether fixed or variable, reduces the choose-short effect with keylight durations but not with food durations. It was concluded that at least some of the psychological processes mediating performance differ as a function of the event that conveys the duration.
