The relation between food deprivation and schedule-induced attack was investigated in four White Carneaux pigeons. Attack toward a mirror target was induced by a schedule of reinforcement in which 3-sec food presentations occurred at alternate intervals of 15 and 120 sec (multiple fixed-time 15-sec fixed-time 120-sec schedule). A continuous tone was presented during the 15-sec periods; it was absent during the 120-sec periods. Each pigeon was tested at 65, 80, and 95% of its free-feeding weight in ascending, descending, and ascending orders, respectively. Two relations were apparent; an inverse relation between body weight and rate of attack, and a tendency for rate of attack to increase during the experiment. Reduction or elimination of attack when the mirror was covered with brown paper for some sessions indicated that the results were due neither to changes in activity that might covary with weight nor to habituation to the experimental situation.
本研究调查了食物剥夺与定时诱发啄击行为之间的关系。在四只白卡奴鸽中进行了实验。啄击镜靶的行为通过一种强化时间表诱发，其中每 3 秒给予一次食物，间隔时间为 15 秒和 120 秒（多次固定时距 15 秒-固定时距 120 秒时间表）。在 15 秒时间段内呈现连续音调；在 120 秒时间段内没有呈现。每个鸽子分别在其自由进食体重的 65%、80%和 95%下进行测试，测试顺序依次为递增、递减和递增。有两个明显的关系；啄击率与体重呈负相关，以及啄击率在实验过程中呈上升趋势。当镜子被棕色纸覆盖几轮后，啄击行为减少或消除，这表明结果既不是由于与体重相关的活动变化，也不是由于对实验情况的习惯化。
