Techniques are described for conditioning key-pecking reinforced with food and for recording cheeping in newly hatched chickens. A mirror in the test box is essential when conditioning isolated chickens up to five or more days old. Conditioning proceeds more rapidly when frequently pecked objects and materials that move when scratched are not present. Stimulus control over key-pecking is present in the three-day-old chicken and multiple fixed-ratio, fixed-interval schedule control develops in succeeding days. In young chickens, pecking and cheeping are inversely related. The newly hatched chicken is useful for pharmacological studies and appears to offer other advantages for behavioral studies.
描述了用于训练以食物强化的按键啄击行为以及记录新孵出小鸡的啁啾声的技术。当训练五天及以上的隔离小鸡时，测试箱中的镜子必不可少。当不存在频繁被啄的物体和被抓挠时会移动的材料时，训练进展得更快。对三天大的小鸡来说，刺激可控制按键啄击行为，并且在接下来的几天中会形成多种固定比率、固定间隔的时间表控制。在幼鸡中，啄击和啁啾声呈负相关。新孵出的小鸡可用于药理学研究，并且似乎为行为研究提供了其他优势。
