Many studies that have investigated performance under reinforcement schedules have measured response rate or interresponse time, which reflect the temporal dimension of responding; however, relatively few studies have examined other dimensions. The present study investigated the effects of fixed-interval schedules on the location of pigeons' pecking response. A circular response area 22.4 cm in diameter was used so that the pecking responses were effective over a wide range. Pigeons were exposed to a fixed-interval schedule whose requirement was systematically varied between conditions. Response location moved closer to the location of the last reinforced response as time elapsed in each trial. Additionally, as the fixed-interval duration requirement increased, response locations shifted to the border of the response area and the variability of response locations increased. These results suggest that fixed-interval schedules systematically control response location.
许多研究强化程序下行为表现的实验测量了反应率或反应间隔时间，它们反映了反应的时间维度；然而，相对较少的研究考察了其他维度。本研究调查了固定间隔程序对鸽子啄击反应位置的影响。使用了一个直径为22.4厘米的圆形反应区域，以便啄击反应在广泛范围内有效。鸽子接受了固定间隔程序，其要求在不同条件下系统地变化。在每次试验中，随着时间的推移，反应位置会向最后一次强化反应的位置靠近。此外，随着固定间隔持续时间要求的增加，反应位置移向反应区域的边界，且反应位置的变异性增加。这些结果表明，固定间隔程序能系统地控制反应位置。
