Abstract

Pigeons were trained to discriminate the presence or absence of a vertical line, and their performance on a subsequent generalization test was compared with that of other pigeons trained to discriminate a vertical from a 45 degrees line. On the generalization gradient after discrimination training, the presence/absence discrimination group showed a peak at 0 degrees (vertical) while the peak for the 0 degrees /45 degrees discrimination group shifted from 0 degrees in a direction away from the 45 degrees line. The results, discussed in connection with a recent suggestion about the role of color in the peak-shift effect, are interpreted as supporting the generality of the phenomenon.

摘要

鸽子经过训练以辨别垂直线的有无,然后将它们在随后泛化测试中的表现与其他训练来辨别垂直线和45度线的鸽子的表现进行比较。在辨别训练后的泛化梯度上,有/无辨别组在0度(垂直)处出现峰值,而0度/45度辨别组的峰值则从0度向远离45度线的方向移动。结合最近关于颜色在峰值转移效应中作用的一项建议对这些结果进行了讨论,这些结果被解释为支持该现象的普遍性。
