本研究通过两个实验探讨了婴儿的发声是否可以通过母亲的偶然模仿和母亲的偶然发声来加强。将这两种治疗的效果相互比较、与基线比较以及与非偶然/联合治疗比较。在第一个实验中，17名3-6个月大的婴儿参与了重复测量的单一处理设计（Br A Bz）：在一个阶段中依次实施三个2分钟的条件：偶然的母亲模仿（Br），非偶然/轭（A）和偶然的母亲模仿（Bz）。在第二个实验中，20名3至5个月大的婴儿参加了重复测量的多重治疗设计（ArBiAzBz）。在第一阶段中，依次实施四种2-n-tin条件：基线（Al）、连续性母体模仿（Br）、非连续性语音（AZ）和偶然性母体模仿（BJ）。在第二个会话中，使用了母亲言语而不是母亲模仿。第一个实验的结果证实了这一假设，即母亲的模仿有效地加强了婴儿的发声。第二个实验表明，母亲模仿产生的婴儿声音反应率最高，偶然的母亲讲话产生的中间率，和noncontingent-yoked治疗产生的最低（即，基线率）。
Two experiments were conducted to investigate whether infant vocalizations can be conditioned by using contingent maternal-imitation and contingent motheresespeech to reinforce the infant’s vocalizations. The effects of these two treatments were compared to each other, to baseline, and to a noncontingent/yoked treatment. In the first experiment, seventeen 3-to-6 month old infants participated in a repeated-measures single treatment design (Br A Bz): three 2-min conditions were implemented sequentially in one session: contingent maternal-imitation (Br), noncontingent/yoked(A), and contingent maternal-imitation (Bz). In the second experiment, twenty 3-to-5-month old infants participated in a repeated-measures multiple treatment design (ArBiAzBz). In the first session, four 2-n-tin conditions were implemented sequentially: baseline (Al), continpent maternal-imitation (Br), noncontinpent-voked(AZ), and contingent maternal-imitation (BJ. In the second session, contingent motherese-speech was used instead of contingent maternal imitation. The order of sessions was counterbalanced with half of the infants experiencing the imitation treatment in the first session.The results of the first experiment confirmed the hypothesis that maternal imitation effectively reinforces infant vocalizations. The second experiment revealed that maternal-imitation produced the highest rates of infant vocal responses, contingent motherese-speech produced intermediate rates, and noncontingent-yoked treatment produced the lowest (ie, baseline rates).
