Two experiments examined 8-month-olds' use of absolute and relative pitch cues in a tone-sequence statistical learning task. Results suggest that, given unsegmented stimuli that do not conform to rules of musical composition, infants are more likely to track patterns of absolute pitches than of relative pitches. A third experiment found that adult…

Used meta-analysis to examine premise that the early child-parent bond is reflected in interpersonal relationships across the life span. Found that overall effect size (ES) for child-mother attachment was small to moderate. ESs were similar in studies using Strange Situation and Q-sort methods. ESs were larger for middle childhood and adolescent…

Examined emergence of a writing system in 4- to 12- year-olds. Found transition occurring around age 6 in which production was more fluent for writing than drawing and activation of one system interfered with the other. Modeling consolidation of both phenomena generated testable parameters for development, involving increasing specialization and…

Examined development of gender role qualities from middle childhood to early adolescence to determine whether children's gender role qualities predicted siblings'. Found that firstborn children's qualities in Year 1 predicted second-born children's qualities in Year 3 when Year 1 parent and child qualities were controlled. Parental influence was…

This study examined the connections between children's self-representations at age 5 and their self-perceptions, socioemotional competence, and peer acceptance at age 8. Findings generally revealed the expected connections between the positiveness of self at age 5 and self-perceptions and socioemotional functioning 3 years later, supporting the…

Examined visual attention and implications for recognition memory in a longitudinal sample of full-term and preterm infants at 5, 7, and 12 months. Found differences between full-terms and preterms in several aspects of visual attention. Infants showed consistent attentional styles over various conditions. Shorter looks and higher shift rates…

Examined relations between components of gender identity and psychosocial adjustment in 182 fourth- through eighth- graders. Found that felt gender compatibility related positively to adjustment, whereas felt pressure and intergroup bias were negatively associated with adjustment. Results help identify sources of confusion in previous research,…

Examined relations between different forms of children's nonsocial play behaviors and adjustment in kindergarten. Results from regression analyses revealed that different types of nonsocial play were differentially associated with child characteristics and indices of adjustment. For some forms of nonsocial play, the nature of these associations…

Examined relations between mothers' expressed positive and negative emotion and 55- to 79-month-olds' regulation, social competence, and adjustment. Structural equation modeling revealed unique effects of positive and negative maternal expressed emotion on children's regulation, and the relations of maternal expressed emotion to children's…

Examined psychological maturity based on personal strivings in 108 adults ages 17 to 82 years. Results supported hypotheses that older people would list more strivings concerning generativity and ego integrity and fewer strivings concerning identity and intimacy, and that maturity and age would be positively associated with subjective well-being.…

Examined associations among positive and conflictual marital behavior and multiple reports of child behavior problems in a community sample of 78 families with 3-year-old children. Found that less positive marital engagement and greater conflict were associated with observers' reports--but not with parents' or teachers' reports--of more behavior…

Reports a cross-sectional investigation of the behavioral and academic correlates of victimization in Chinese children's peer groups. Structural equation models indicated that peer victimization was associated with poor academic functioning, submissive-withdrawn behavior, aggression, and low levels of assertive-prosocial behavior. Findings suggest…

Evaluated brainstem auditory evoked responses (BAERs) on 10- to 12-year-olds who had been classified as high or low reactive to unfamiliar stimuli at 4 months of age. Found that children previously classified as high reactive at 4 months had larger wave V components than did low reactive children, possibly suggesting greater excitability in…

A longitudinal study examined memory span at 5, 7, and 12 months in full-term and low-birth-weight preterm infants. Findings were similar for both groups: longer spans were more difficult, especially at younger ages, memory capacity increased over first year of life, there was marked recency effect for spans of 3 and 4 at all ages, and modest…

Used short-term longitudinal design to examine peer relations processes that may mediate relation between peer rejection and kindergartners' emotional and academic adjustment. Structural equation modeling results supported hypothesis that negative peer treatment and classroom participation partially mediated the relationship between rejection and…
