The effect of several reinforcement schedules on the variability in topography of a pigeon's key-peck response was determined. The measure of topography was the location of a key peck within a 10-in. wide by 0.75-in. high response key. Food reinforcement was presented from a magazine located below the center of the response key. Variability in response locus decreased to a low value during training in which each response produced reinforcement. Variability increased when fixed intervals, variable intervals, random intervals, or extinction were scheduled.
几种强化程序对鸽子啄键反应地形变异的影响。地形的衡量标准是啄键的位置,在一个 10 英寸宽、0.75 英寸高的反应键内。食物强化来自位于反应键中心下方的杂志。在每个反应都产生强化的训练中,反应轨迹的变异降低到低值。当安排固定间隔、可变间隔、随机间隔或灭绝时,变异性增加。
