Maternal vocal imitation of infant vocalizations is highly prevalent during face-to-face interactions of infants and their caregivers. Although maternal vocal imitation has been associated with later verbal development, its potentially reinforcing effect on infant vocalizations has not been explored experimentally. This study examined the reinforcing effect of maternal vocal imitation of infant vocalizations using a reversal probe BAB design. Eleven 3- to 8-month-old infants at high risk for developmental delays experienced contingent maternal vocal imitation during reinforcement conditions. Differential reinforcement of other behavior served as the control condition. The behavior of 10 infants showed evidence of a reinforcement effect. Results indicated that vocal imitations can serve to reinforce early infant vocalizations.
母亲对婴儿发声的模仿在婴儿及其照顾者的面对面互动中非常普遍。尽管母亲对婴儿发声的模仿与后期的言语发展有关,但它对婴儿发声的潜在强化作用尚未通过实验进行探索。本研究使用反转探针 BAB 设计来检验母亲对婴儿发声的模仿的强化作用。11 名患有发育迟缓高风险的 3 至 8 个月大的婴儿在强化条件下经历了母亲的伴随发声模仿。其他行为的差异强化作为对照条件。10 名婴儿的行为表现出强化效应的证据。结果表明,发声模仿可以起到强化早期婴儿发声的作用。
