The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with…

A prominent hypothesis holds that by speaking to infants in infant-directed speech (IDS) as opposed to adult-directed speech (ADS), parents help them learn phonetic categories. Specifically, two characteristics of IDS have been claimed to facilitate learning: "hyperarticulation," which makes the categories more "separable," and…

Mental state terms are believed to be closely related to the development of Theory of Mind (ToM). This study focuses on mental state verbs (MSVs) and investigates how they are used by Japanese-speaking mother-child dyads compared to their English-speaking counterparts. Analyses of their spontaneous speech from the CHILDES archives show that…

Although the Japanese reflexive "zibun" can be bound both locally and across clause boundaries, the third-person pronoun "kare" cannot take a local antecedent. These are properties that children need to learn about their language, but we show that the direct evidence of the binding possibilities of "zibun" is sparse…

Much work on child sentence processing has demonstrated that children are able to use various linguistic cues to incrementally resolve temporary syntactic ambiguities, but they fail to use syntactic or interpretability cues that arrive later in the sentence. The present study explores whether children incrementally resolve filler-gap dependencies,…

This study aimed to clarify factors related to difficulties in responding to "yes/no" questions (Y/N-Qs) among 52 children with autism spectrum disorder (ASD), 41 boys and 11 girls aged between 3:5-16:0 years. Participants completed the Tanaka-Binet Intelligence Scale V, the Picture Vocabulary Test: Revised (PVT-R), and the Pervasive…

Two Japanese universities are undertaking a research program in child language by studying children's verbal and nonverbal development, sponsoring lectures on child language and holding an annual symposium on related subjects. (CK)

With reference to Fenson's (1984) study of American children's pretend actions and utterances, this study examined the development of pretend actions and utterances in the play of 16 Japanese firstborn children. Subjects, whose cognitive and language development had been followed experimentally since the age of 6 months, were nonretarded…

Examined in a longitudinal study of children were correspondences and correlations between early language development on the one hand, and the manipulation of objects and play development on the other. There were developmental correspondences between the onset of five language landmarks (the emergence of first word, referential word, demonstrative…

Examined whether the characteristics in perception of speech sounds found in preverbal hearing infants might extend to the perception of signed language in infants with congenital deafness. Seventeen Japanese mother-infant dyads participated in the study. Found that infants with deafness showed greater attentional and affective responsiveness to…

To investigate cross-sectionally and longitudinally the development of children's early verbal behavior, 10 normal first-born Japanese infants from middle-class families were observed monthly and examined from when they were 6 to 24 months of age. Audio- and video-taped language data were obtained in a laboratory playroom setting during 15-minute…

Mothers in Argentina, France, Japan, and the United States were observed interacting with their 5- and 13-month-old infants. Maternal speech was classified into expressions concerning affect and information. Mothers in all cultures used both classifications with their infants and spoke to older infants more than younger infants. (BC)

The form of Japanese children's personal narratives is distinctly different from that of English-speaking children. Despite follow-up questions that encouraged them to talk about one personal narrative at length, Japanese children spoke succinctly about collections of experiences rather than elaborating on any one experience. Conversations between…

Comparison of maternal speech to three-month-olds between American (N=20) and Japanese (N=20) mother-infant dyads revealed that infant gaze affected the intended functions of maternal speech differently for the two groups. Cultural differences were also seen in the nature of function-form and function-referent relationships. (Author/CB)

A 3-years-and-11-months-old Japanese girl showed delayed language development and emotional disturbance and was believed to suffer from maternal deprivation. A treatment program was developed consisting of three kinds of therapy: (1) nondirective play therapy; (2) language training; and (3) counseling for the mother. The language training involved…
