Two studies investigate young children's beliefs about aggression and withdrawal in others with reference to the possibility of stability and change. Study 1 (N = 41) provides evidence that preschool children (1) view aggression in more essentialist ways (i.e. they believe it to be more stable and less changeable) than withdrawal and (2) believe…

Explored the effect of person familiarity and parental involvement on 3.5-month-old infants' sensitivity to the dynamic emotion expressions of others. Found that infants looked differentially at mothers' expressions but not at those of fathers or unfamiliar adults, and that parent-child involvement significantly influenced infants' developing…

This study examined the relationship of crossing the midline while reaching for objects to the development of bimanual reaching among infants ages 12, 18, and 26 weeks. Findings indicated that the frequency of two-hand grabbing and the number of midline reaches increased with age; most midline reaches were part of two-handed reaches and occurred…

Three studies investigated the extent to which kindergartners, second-graders, and undergraduates were susceptible to the Deese/Roediger/McDermott (DRM) illusion, an adult false-memory paradigm. Findings indicated that the DRM illusion was at nearly non-existent levels in young children, and was still below adult levels in adolescence. The low…

Three studies investigated how 3-year-old Japanese children interpret the meaning of a new word associated with a familiar artifact. Findings suggest that children flexibly recruit clues from multiple sources, including shape information and function familiarity, but the clues are weighed in hierarchical order so children can determine the single…

Compared reading development among kindergartners in Hong Kong and the United States using measures of word recognition, phonological awareness, speeded naming, visual spatial skill, and processing speed. Found that models of early reading development were similar across cultures. The strongest predictor of reading was phonological awareness.…

Four studies explored children's beliefs about the stability of positive traits among three groups. Findings indicated that younger children were more likely than older children or adults to believe that negative physical and psychological traits would change positively, that they could control the expression of a trait, and that extreme positive…

This study investigated 2-year-olds' understanding of others' intentions in a social learning context. After seeing a demonstration of how to open a box, children in two "No Prior Intention" conditions were less likely than those in "Prior Intention" conditions to open the box themselves when the adult unsuccessfully tried to open it. Results…

Three studies examined theory-of-mind concepts among children ages 6-13 years with deafness or autism, and 4-year-olds with normal development. Findings indicated that while the children with deafness or autism scored significantly lower on standard tests of false belief understanding, they scored higher on even the most challenging drawing-based…

Investigated associations among constructive and destructive sibling conflict, pretend play, internal state language, and sibling relationship quality among sibling pairs with one kindergarten-age child. Found that specific resolution strategies were associated with conflict issues, aggression and internal state language, and that conflict issues…

Examined longitudinally changes in inhibition from toddler age to age 4 and age 7 years. Found that temperament change in children who tested as inhibited or uninhibited as toddlers was more common than remaining extremely inhibited or uninhibited, but that change was largely limited to intermediate groups. Subgroups distinguished by responses on…

Investigated the long-term effects of social disadvantage on academic achievement and subsequent attainments in adulthood. Found that the influence of risk factors for socioeconomic disadvantage depended on developmental stage, the experience of long-term or continuous disadvantage, and sociohistorical context. Greatest risk was associated with…

Examined the relationship between maternal psychological functioning and child competence and psychological adjustment among black families with 11-year-old children. Found a chain of influences over a 3-year period in which maternal education and income were linked with maternal psychological functioning, which predicted competence-promoting…

This longitudinal study investigated the validity of the Five Factor Model of personality with Swedish children ages 2 to 15 years. Findings of item analyses showed consistently reliable irritability, conscientiousness, and positive activity factors, while internal reliability of other factors increased over time. Found that irritability and…

Examined the effects of child maltreatment and interadult violence on children's developing strategies of emotion regulation and socioemotional development, and the role of emotion dysregulation in mediating the link between children's pathogenic relational experiences and behavioral outcomes for 3- to 6-year-olds. Found that maltreatment history…
