我们报道了四个探索声音模仿的认知基础的实验。具体地说，我们调查了正常人用声音模仿口语句子和唱出的旋律的音高-时间轨迹的准确性，这些句子和旋律以原始形式呈现，并去掉了语音信息。总体而言，参与者在绝对音高方面比句子更准确地模仿旋律，但在相对音高或时间(总时长)方面则不是这样。值得注意的是，语音信息的存在促进了对旋律和语音的模仿。对不同研究的个体差异分析表明，模仿歌曲的准确性预示着模仿语音的准确性。总体而言，这些结果与强调信息封装的模块基音处理的描述不一致。(C)2013爱思唯尔B.V.保留所有权利。
We report four experiments that explored the cognitive bases of vocal imitation. Specifically, we investigated the accuracy with which normal individuals vocally imitated the pitch-time trajectories of spoken sentences and sung melodies, presented in their original form and with phonetic information removed. Overall, participants imitated melodies more accurately than sentences with respect to absolute pitch but not with respect to relative pitch or timing (overall duration). Notably, the presence of phonetic information facilitated imitation of both melodies and speech. Analyses of individual differences across studies suggested that the accuracy of imitating song predicts accuracy of imitating speech. Overall, these results do not accord with accounts of modular pitch processing that emphasize information encapsulation. (C) 2013 Elsevier B.V. All rights reserved.
