White King pigeons exposed to food schedules before introduction of a colored photograph of a pigeon showed sustained schedule-induced attack on that image; additional birds given an early introduction to both the photograph and the schedule subsequently attacked the image at lower rates. Other pigeons attacked a second photograph of a pigeon regardless of whether it was introduced early or late. The late-introduction procedure was also effective in establishing attack on a projected image of a conspecific. The combined results showed that 14 of 17 White King pigeons given a late introduction to a pictorial target exhibited sustained attack against it and that a pigeon's initial reaction to a photograph of a conspecific when introduced early was a good predictor of subsequent schedule-induced attack on it.
在展示鸽子彩色照片之前，让白王鸽接触食物时间表，结果显示它们对该图像表现出持续的由时间表诱导的攻击行为；另外一些鸽子在早期同时接触照片和时间表，随后对图像的攻击频率较低。其他鸽子无论照片是早介绍还是晚介绍，都会攻击第二张鸽子照片。晚介绍程序在建立对同种个体投影图像的攻击方面也很有效。综合结果表明，17只白王鸽中有14只在晚接触图像目标时对其表现出持续攻击，并且鸽子在早期接触同种个体照片时的初始反应是后续由时间表诱导的对该照片攻击的良好预测指标。
