Each of a group of one-month-old infants was reinforced, contingent upon nonutritive sucking, with its mother's voice and the voice of a stranger. In this experiment, two conditions were applied. Under the first, the mother's speech was aimed at communicating with the infant, while, under the second, the mother's speech lacked prosodic and intonational aspects of normal speech. It was shown that infants will suck more for their mother's voices under the intonanted condition only. It was concluded that a young infant prefers its own mother's voice provided the mother speaks normally.
一组一个月大的婴儿，每一个在非营养性吸吮时，都会得到母亲的声音和一个陌生人声音的强化。在这个实验中，应用了两种条件。在第一种条件下，母亲的言语旨在与婴儿交流，而在第二种条件下，母亲的言语缺乏正常言语的韵律和语调方面。结果表明，婴儿仅在有语调的条件下会为母亲的声音吸吮得更多。得出的结论是，只要母亲正常说话，年幼的婴儿更喜欢自己母亲的声音。
