Young chickens were given 1, 10, 100, or 1000 presentations of grain in a hopper. Subsequently, the key was illuminated before each presentation of grain to study autoshaping of the key-peck response. The number of keylight-grain pairings before a bird first pecked the lighted key was found to be a U-shaped function of the number of prior food-only presentations, with pecks occurring significantly sooner after 100 food-only trials than after any of the other values. Two of five chicks at the 100-trial value pecked on the first illumination of the key. Experiment II showed further that when a series of food-only trials (no keylight) preceded keylight-only trials (no food) 30% of the chicks pecked the illuminated key. Experiment III extended the generality of first-trial pecking to pigeons. After preliminary training with food-only, two of five pigeons pecked on the first illumination of a key. The results suggest a close relationship between autoshaping and pseudo-conditioning.
将 1、10、100 或 1000 粒谷物呈现在鸡面前。随后，在每次呈现谷物之前，都会点亮钥匙，以研究钥匙啄响应的自动塑造。在鸟类第一次啄亮钥匙之前，啄亮钥匙与亮灯-谷物配对的次数是一个 U 形函数，与 100 次仅食物试验相比，啄亮钥匙的次数明显更早。在 100 次试验值的 5 只小鸡中有 2 只在第一次点亮钥匙时啄食。实验二进一步表明，当一系列仅食物试验（无钥匙灯）在前，而钥匙灯仅试验（无食物）在后时，30%的小鸡会啄亮钥匙。实验三将首次啄食的普遍性扩展到了鸽子。在仅用食物进行初步训练后，5 只鸽子中有 2 只在钥匙第一次被点亮时啄食。结果表明，自动塑造和伪条件反射之间存在密切关系。
