项目摘要

Developmental changes in infants' vocal expressions of emotion were investigated via acoustical and perceptual experiments. Analyzing voice samples recorded at mother/infant or unfamiliar-adult/infant vocal interactions, the following hypotheses were obtained. 1)Very young infants, even of 6 to 9 month of age, can produce various qualities of voice with wide ranges of fundamental frequency and intensity. 2)Infants tend to emerge prosodic patterns which are influenced by their ambient language at about 8 to 10 month of age. Even before those months of age, however, they produce various voice qualities which carvmay be perceived by adult listeners as emotional expressions. 3)Infants' vocalization may change due to by whom and how they are interacted. Details of emotional aspects of infants' vocalizations recorded at mother/infant interactions were analyzed through perceptual experiments. Crying was not included. Results showed that ratings for most vocalizations recorded at 6/9 months of age were high mainly for the terms expressing positive emotions such as "amaeru" and "pleasure". On the other hand, ratings for those recorded at 11/17 months of age were high not only for positive emotional terms like "happy" and "pleasure", but also for negative emotional terms such as "refusal" and "anger. " These results indicate that infants' vocalizations at very early of age or the babbling stage contain wide variety of acoustic characteristics which may convey various emotional expressions, but those conveying negative emotional aspects without crying might still be developing at least during 9/11 months of age. Relationships between emotional aspects and linguistic organization of infants' vocalization are now being investigated.

通过听觉实验和知觉实验，研究了婴儿声音情感表达的发展变化。分析母亲/婴儿或陌生成人/婴儿声音互动时记录的声音样本，得出以下假设。1)非常小的婴儿，即使是6到9个月大的婴儿，也可以发出各种不同的声音，具有广泛的基频和强度。2)婴儿在8 ~ 10个月大时，受周围环境语言的影响，往往会出现韵律模式。然而，即使在这几个月大之前，他们就能发出各种各样的声音，成年人听了这些声音就能感觉到他们的情感表达。3）婴儿的发声可能会因与谁互动以及如何互动而发生变化。通过知觉实验分析了在母婴互动中记录的婴儿发声的情感方面的细节。哭不包括在内。结果表明，大多数发声记录在6/9个月大的评级高，主要是表达积极的情绪，如“amaeru”和“快乐”的条款。另一方面，在11/17个月大的孩子中，不仅对“快乐”和“快乐”等积极情绪术语的评分很高，而且对“拒绝”和“愤怒”等消极情绪术语的评分也很高。“这些结果表明，婴儿在很小的年龄或牙牙学语阶段的发声包含各种各样的声学特征，这些特征可能传达各种情绪表达，但那些传达负面情绪方面而不哭泣的声音可能至少在9/11个月大的时候仍然在发展。婴儿发声的情感因素和语言组织之间的关系正在研究中。
