The acquisition and maintenance of autoshaped key pecking in pigeons was studied as a function of intertrial interval. At each of six intervals, which ranged from 12 seconds to 384 seconds, four pigeons were physically restrained during training while four other pigeons were not restrained. Restrained subjects acquired key pecking faster and with less intragroup variability at each interval. The effects of restraint were specific to acquisition and were not evident in maintained responding after five postacquisition sessions.
研究了鸽子的自动啄键习得和维持功能与试验间隔的关系。在六个间隔时间(12 秒到 384 秒)中的每一个间隔时间内,有四只鸽子被物理束缚在训练中,而另外四只鸽子没有被束缚。被束缚的鸽子在每个间隔时间内更快地习得啄键,并且组内变异性更小。束缚的影响是特定于习得的,并且在五个习得后会话后的维持反应中并不明显。
