In these studies, descriptive information on the diet and feeding behavior of ring dove squab is considered in the context of an analysis of the mechanisms underlying the development of eating. Experiment I shows that squab begin to peck at grain around Day 13 and both the rate and efficiency of pecking increase through Day 21 when the squab are weaned. Experiment II shows that squab reared without seed in their home cage do not develop normal levels of pecking unless exposure to seed is followed in close temporal proximity by interaction with parents. It is concluded that an association between some aspect of squab's interaction with seed and a parentally provided unconditioned stimulus is sufficient for normal pecking to develop. The nature of these associations and their contribution to the ontogeny of independent feeding are discussed.
在这些研究中，在对进食行为发展的潜在机制进行分析的背景下，考虑了关于环鸽雏鸽饮食和进食行为的描述性信息。实验一表明，雏鸽在第13天左右开始啄食谷物，到第21天雏鸽断奶时，啄食的速度和效率都有所提高。实验二表明，在家笼中饲养且没有种子的雏鸽，除非在接触种子后紧接着与亲鸟互动，否则不会发展出正常水平的啄食行为。研究得出结论，雏鸽与种子互动的某些方面与亲鸟提供的无条件刺激之间的关联足以使正常啄食行为得以发展。讨论了这些关联的性质及其对独立进食个体发育的贡献。
