This study examined socioeconomic gradients in different domains of early child development using data from the validation sample of the East Asia-Pacific Early Child Development Scales. The Scales were administered to 7797 3- to 5- year-olds (3889 girls) from Cambodia, China, Mongolia, Papua New Guinea, Timor-Leste, and Vanuatu and children's…

There are many postulates of a relation between quality of attachment with theory of mind and language functions (e.g., de Rosnay & Hughes, 2006). The current study examined in longitudinal design how different patterns of attachment are associated with usage of internal state language at ages 17, 23, 30 and 36 months. Transcripts of mother-child…

Thirty-five children who had participated in a study of mastery motivation at one year of age were reevaluated at 3.5 years. Findings differed for boys and girls and indicated that a wide range of behaviors in the cognitive-motivational domain must be examined to find developmental continuities. (Author/CB)

Data from 226 adoptive and 224 nonadoptive families was used to explore the etiology of individual differences in communication development. Children's scores from the Sequenced Inventory of Communication Development (SICD) were compared with verbal and cognitive ability measures of their parents. Sibling correlations were also examined. (SKC)

Although both environmental and cognitive factors were found to predict language development, cognitive factors appear to be more significant in the early months and environmental factors become more significant later in development. (MP)

Describes growth in the number of studies of behavior development conducted in Japan during the last 20 years and identifies areas of development receiving attention by Japanese researchers. (RH)

Children and adults were asked to place something "in front of" or "behind" a featured or nonfeatured object. Most subjects responded to the object's inherent features. A significant number of adults used the observer orientation cue. Children had more difficulty with the nonfeatured object but also used the observer…

Introduces the common theme among the papers presented in this issue, the development of working memory. Underlines the two different approaches presented. The neo-Piagetian perspective attempts to capitalize on the insights of Piaget's work by proposing information-processing accounts of cognitive development. The second perspective stems from…

Factor analysis of correlations among the measures of recall clustering, free sorting, and recognition errors revealed significant convergent validity for consistent use of a semantic perceptual organization strategy in the three tasks. Ten-year-old, adult, and elderly adult subjects relied on a semantic strategy; four- and six-year-olds encoded…

Examined whether speech rate is related to the amount recalled and if developmental increases in speech rate allow faster rehearsal with age, and hence, greater recall. Found that the group relationship was clear and replicable but that speech rates of individual children were not good predictors of those children's memory spans; age was found to…

A study of 13 14-month-old and 12 18-month-old children found that the younger infants relied more on gestures and fussing to express their physical wants, whereas the older infants relied more on vocal responses, especially when clarification of their wants was needed. (MDM)

A brief history of Chinese developmental psychology is given, and current main research projects are highlighted. (Author/MP)
