Autism spectrum condition (ASC) is characterized by atypical attention to eyes and faces, but the onset and impact of these atypicalities remain unclear. This prospective longitudinal study examined face perception in infants who develop ASC (N = 22, female = 5, 100% White) compared with typically developing infants (N = 131, female = 65, 55.6%…

This paper is in memory of Esther Thelen, who passed away while President of the Society for Research in Child Development. A survey of Esther Thelen's career reveals a trajectory from early work on simple movements like stepping, to the study of goal-directed reaching, to work on the embodiment of cognition, and, ultimately, to a grand theory of…

Provides an introduction to a special section on developmental behavioral genetics (the study of genetic and environmental influences on individual differences in behavioral development), discussing the potentialities of the interdiscipline and presenting an overview of the following articles. (Author/RH)

Studied 112 preterm infants to determine developmental changes and stability of individual differences. Results indicate significant developmental gains with age, and highly significant individual stability of performance across age. (RJC)

Verbal and behavioral measures of children's knowledge are frequently dissociated. These situations represent a largely untapped but important resource for furthering an understanding of human cognition. In this paper, verbal-behavioral dissociations in children are discussed and analyzed, drawing from a wide range of domains. The article explores…

Mothers were interviewed periodically over the first six years of their same-sex twins' lives and were asked to contrast them on specific behaviors. Intrapair contrasts were moderately stable across age spans for as long as 18 through 36 months. Genotypic similarity was apparently associated with intrapair similarity in emotionality and…

Considers areas of consensus from commentaries, including the value of an evolutionary perspective and the utility of exploring variations in physical activity play. Examines areas of debate, including the nonplay-play distinction, functions of rough-and-tumble play, and the opportunities of juveniles for exercise training. Calls for more directed…

Tested infants in their second year with a box task to determine whether they would show a hand preference in solutions involving complete differentiation of roles for the two hands. (HOD)

Assessed, at 8-10 months, children's restraint and attention, and at 13-15 months, compliance to mother, internalization of her prohibition, and quality of motivation of the mother-child teaching context. Found support for view of compliance and noncompliance as heterogenous: committed compliance was higher to maternal "don'ts" than…

Proposes and tests an attributional model of parent social cognition and examines parents'inferences about why everyday child behaviors occur and what consequences these inferences may have for socialization. (HOD)

Maintains that the "getting into shape" hypothesis of explaining the inverted-U distribution of exercise play across age is likely incorrect. Argues that the biological study of human physical activity play, as recommended by Pellegrini and Smith (1998), will reveal whether physical activity play represents an example of…

This multi-method study sought to identify parameters of developmental change and stability of child reaction patterns to interparental conflict in the context of family relations in a sample of 223 6-year-old children and their parents followed over the course of one year. Consistent with the sensitization hypothesis, interparental withdrawal and…

Reports on a longitudinal study that provides a prospective view of children's personality functioning prior to their subsequent experiencing of divorce. Shows the behavior of boys as early as 11 years prior to parental separation or formal dissolution of marriage to be consistently affected by predivorce familial stress. (HOD)

Comments on Belsky, Steinberg, and Draper's article in this issue. Offers three likely reasons for adaptation of human behavior. Argues that Belsky, et al. use only two of these reasons in their proposed evolutionary theory of socialization. Suggests that an evolutionary approach is useful if it integrates diverse facts, aids clinical practice,…

Examines whether there are sex differences during middle childhood in children's choices to participate in activities differing in level of adult-provided structure; effects of structure on children's compliance, leadership, and recognition seeking directed to adults and to peers; and relation of sex-typed social skills or dispositions and…
