Used a dynamic systems (DS) approach to study changes in structure of family interactions in problem-solving sessions during the early adolescent transition of boys in 149 families. Constructed state space grids (a new DS method) for families across five waves of videotaped data collection before, during, and after the transition. Found that DS…

Tested links between early adolescent older sibling (OS) and younger sibling (YS) competence in rural African American families. Found that OS competence was stable across time and related to improvements in mothers' psychological functioning from Wave 1 to Wave 2. Mothers' Wave-2 psychological functioning related to Wave-3 involved-supportive…

Examined European-American 19-year-olds' self-defining memories about relationships with parents and/or peers.

Parental separation was exemplified by parental divorce experiences, parent closeness by comforting a grieving parent, and peer…

Compared preschoolers with autism spectrum disorders with a matched control group to investigate whether weak central coherence could account for deficits in two behaviors purported to tap capabilities fundamental to a theory of mind: joint attention and pretend play. Found that pretend play did not differentiate the two groups. Weak central…

Examined autonomy and individuation levels within financial, residential, romantic, and family formation domains among 17- to 27-year-olds in a community-based longitudinal study. Found that subgroup differences related to family socioeconomic status, parental divorce, gender, or race were not generally attributable to educational enrollment. Both…

Examined children's and adolescents' ability to identify male sweat and other odors and their rating of odors for liking. Found that only female adolescents could identify and disliked male sweat. When cued about odor identity, both male and female adolescents disliked male sweat more than children. Concluded that dislike for male sweat odor may…

Examined toddlers' self-regulated compliance to mothers, fathers, and caregivers. Found child emotion regulation and adult warm control in discipline situation related to self-regulated compliance to mother, caregiver, and father. Compliance to parents correlated with parental sensitivity and philosophies. Compliance to caregivers correlated with…

Two experiments examined how different frustration contexts affect the instrumental and emotional responses of 4- to 5-month-olds. Both experiments showed that arm responses increased when the contingent stimulus was lost or reduced but decreased when control of the stimulus was lost under noncontingency. Facial expressions of anger, but not…

Three experiments explored infants' attention to conflicting cues at different ages. Found when stress and statistical cues indicated different word boundaries, 9-month-olds used syllable stress as a cue to segmentation while ignoring statistical cues. Seven-month-olds attended more to statistical cues than to stress cues. Results suggested…

Two studies examined whether differences in the lexical explicitness with which languages (English, Spanish, Portuguese, Turkish) express false belief and preschoolers' socioeconomic status (SES) influenced children's performance on standard false belief tasks. Found that lexical explicitness influenced responses on the "think" false belief…

Estimated effects of high participation in Infant Health and Development Program targeting low-birth-weight (LBW) premature infants. Found that at age 8, effects of attending more than 400 days on scores on the Weschler Intelligence Scale for Children Full and Verbal Scales was 7 to 10 points.

Three studies investigated 3-year-olds' comprehension of indirectly and directly learned words after a 2-day delay. Found indirectly and directly learned proper and common names resulted in proper name mappings that picked out individual and common name mappings that could be extended to another category member. When additional, sometimes…

Examined relations of effortful control and ego control to children's resiliency, social status, and social competence concurrently (Time 3) and over time. Found that at Time 3, resiliency mediated the unique relations of effortful and reactive control to social status, and effortful control directly predicted socially appropriate behavior.…

Examined main and interactive effects of multiple social risk factors and preschool IQ and mental health on students' academic trajectories from first to twelfth grade. Found that high-risk students had lower grades and more absences from first to twelfth grade than low-risk students. Higher IQ and better mental health improved the grade point…

Three experiments examined 4- to 10-month-olds' perception of audio-visual (A-V) temporal synchrony cues in the presence or absence of rhythmic pattern cues. Results established that infants of all ages could discriminate between two different audio-visual rhythmic events. Only 10-month-olds detected a desynchronization of the auditory and visual…
