D-14 強化子提示を待つ間の衝動性と自己制御

抄録

Pigeons could earn a smaller-sooner reinforcer provided by a fixed-ratio one schedule (an SS alternative) or a larger-later reinforcer provided by a 10-s temporal schedule (an LL alternative), which was either a response-dependent, response-independent, or pausing-dependent schedule in separate conditions. The SS alternative was presented after certain duration of delay, which varied daily, had passed from the onset of the LL alternative. Results showed that the later the SS alternative was presented, the less frequently the pigeons chose it. Although the different schedules of the LL alternative maintained differential responding, the responding itself had little effect on choice.
