Little is known about the across time stability of autistic traits during the transition period from preschool to school age in the general population. The current study compared autistic traits assessed by a mother-reported quantitative measure, the Social Responsiveness Scale, at age 5 and 8 years and examined the intraclass correlation…

Objectives: Motor deficits related to imitation have been observed in autism spectrum disorder (ASD) patients. This pilot investigation focused on motor performances, including daily tool-use actions, performing an action in the absence of the tool, and imitating (copying tool-use action presented visually), in eight children with ASD and eight…

Children with developmental disorders often have poor motor performance. This study aimed to address the association between tactile localization ability, an indicator of body image, and motor function in children with motor deficits. Eighteen children with motor deficits participated, and their upper and lower limbs were assessed. To assess the…

To determine the best discriminative items for identifying young children with autism spectrum disorders (ASD), we conducted a secondary analysis using longitudinal cohort data that included the Japanese version of the 23-item modified checklist for autism in toddlers (M-CHAT-JV). M-CHAT-JV data at 18 months of age and diagnostic information…

This article briefly reviews the history of intellectual assessment with children and youth in Japan, as well as current practices and future directions. The history of intelligence test use in Japan began in the early 20th century. Since the 21st century, three major intelligence tests, namely, the Wechsler Intelligence Scales, the Kaufman…

This study investigates how adults in two contrasting cultures (Italian and Japanese) perceive episodes of crying of typically developing (TD) children and children with Autism Disorder (AD). Although cries of children with AD have been reported to elicit more distress in Western cultures, it is not known whether similar findings hold in Eastern…

Speech-language pathology has different practice and research histories, standards, methods, and challenges in different countries and regions. Awareness of these different realities may contribute to the scientific development of the field and improve the services delivered to different populations. Sharing solutions to similar problems in…

Although autism is now recognized as being very common (Buie et al., 2010) and as developing due to not only genetic but also environmental factors, there is insufficient epidemiological evidence on the relationship between autism and allergy. In this study, therefore, we attempted to clarify the association of environmental factors with autism…

The purpose of this study was to empirically investigate a family-centered approach to positive behavior support (PBS) that was designed to be culturally responsive to families of diverse linguistic and cultural backgrounds. A Japanese mother and a child with autism were the primary participants. Multiple research methods were used. A…

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…

This paper examined the processes that resulted in an adult failing to comprehend the intentions of a boy with high-functioning autism. In a dyadic conversation between an adult and a young boy, the adult used questions to elicit clarification of intentions. The boy's responses were examined frame-by-frame using videotape microanalysis. Two causes…

Based on an observational study of children (ages 3-7) screened at a child guidance center in Japan, the prevalence rate of infantile autism in each one-year birth cohort (1972-1978) fluctuated in a four-year cycle which was closely correlated with the number of children hospitalized with lower respiratory tract diseases.

Analysis of diagnostic questionnaires completed by Japanese parents of 141 autistic children below the age of 12 found that the Japanese peak of abnormal social behavior, including autistic symptoms as reported by parents, was from the ages of 3 to 9 years as compared with the U.S. and European peak of 3 to 6 years.

To compare Japanese autistic children's use of semantic knowledge and theory of mind with mentally retarded and typically developing children's, they were tested on their comprehension of active and passive sentences and false belief understanding. Autistic children were sensitive to plausibility levels of semantic bias as were 4-year-olds with…
