Researchers studying learning and memory in the day-old chick have developed a one-trial taste avoidance learning task, in which a chick pecks a bead coated with an aversive-tasting liquid such as methylanthranilate. The current study examined, in two experiments, whether chicks could demonstrate learning of an appetitive version of the one-trial task, and how long this memory might last. The results demonstrate that chicks show significantly decreased latencies to peck a test bead similar to that pecked at training coated with water, and that this memory lasted for at least 6 h after training. These results demonstrate that this appetitive task produces significant learning.
研究一日龄雏鸡学习与记忆的研究人员开发了一种单次尝试味觉回避学习任务，在该任务中，雏鸡啄食一颗涂有厌恶味道液体（如邻氨基苯甲酸甲酯）的珠子。当前的研究在两个实验中检验了雏鸡是否能表现出对单次尝试任务的偏好性版本的学习，以及这种记忆可能持续多长时间。结果表明，雏鸡啄食与训练时啄食的涂有水的测试珠子相似的珠子的潜伏期显著缩短，并且这种记忆在训练后至少持续6小时。这些结果表明，这种偏好性任务产生了显著的学习效果。
