Assessed interaction between obstetrical complications and early family adversity in predicting violent behavior during childhood and adolescence among 849 boys from low SES areas. Found that elevated scores on scale of obstetrical complications (preeclampsia, umbilical cord prolapse, induced labor) increased risk of being violent at 6 and 17…

Examined predictability of observed parent-child interaction from preschool to middle childhood among 283 mother-child dyads who were welfare recipients enrolled in a job training program. Found that interaction in middle childhood could be predicted from observed interaction 4 years earlier. Families with greater risk factors tended to show more…

Evaluated new self-report measure assessing children's strategies for preserving emotional security in context of interparental conflict. Factor analyses of the Security in the Interparental Subsystem (SIS) Scale supported a 7-factor solution. The SIS demonstrated satisfactory internal consistency and test-retest reliability. Support for test…

Examined effects of domain-differentiated beliefs about legitimate parental authority, and ratings of restrictive parental control and adolescent- and mother- reported psychological and behavioral control. Found that domain-specific parenting beliefs and ratings predicted adolescent-reported maternal psychological control and parental monitoring.…

Examined relations between sibling jealousy and child and family characteristics in families with toddler and preschool-age siblings. Found that positive marital relationship was particularly strong predictor of older siblings' abilities to regulate jealousy in sessions with mothers. Younger siblings' jealous affect with mothers related to child's…

Used a three-group design to determine the effects on child development of the Minnesota Family Investment Program (MFIP), a state welfare reform program. Findings showed that MFIP increased employment rates and decreased poverty. According to mother-reports, children were less likely to exhibit problem behaviors and more likely to perform better…

Examined relations between patterns of marital communication, child adjustment, and family functioning. Subjects were couples observed to be hostile, hostile- withdrawn, or engaged, and having a 4- or 5-year-old child. Found that families in which couples were hostile-detached showed the most negative outcomes. Marital typology accounted for…

Three experiments investigated discrimination and memory of 5.5-month-olds for videotapes of women performing different activities (blowing bubbles, brushing hair, brushing teeth) or static displays after a 1-minute and a 7-week delay. Findings demonstrate the attentional salience of actions over faces in dynamic events to 5.5-month-olds. Findings…

One longitudinal and one cross-sectional study evaluated the interactive effects of endogenous and exogenous influences on infants' attention allocation by assessing the role of target familiarity on distraction latency during object exploration. Findings indicated that 9- and 10-month-olds, but not 6.5-month- olds, exhibited longer latencies as…

Three experiments examined development of perceptual causality in 3- to 9-year-olds. Findings indicated that participants of all ages assigned contact events (A moves toward B, which moves upon contact) to the physical domain and non-contact events (B moves before contact) to the psychological domain. Participants chose causality more often for…

Related blood levels of testosterone and sex hormone-binding globulin in pregnant women to gender role behavior among 342 male and 337 female offspring at 3.5 years. Found that testosterone levels related linearly to girls' gender role behavior. Neither hormone related to boys' gender role behavior. Other factors, including older brothers or…

Five experiments examined whether young children believe a lie tellers' implausible statement about a misdeed when the statement violates their developing knowledge of the reality- fantasy distinction. Findings suggested that 5- and 6-year-olds tended to report that the individual making the implausible statement actually committed the misdeed; 3-…

Two studies examined age-related change in proactive interference from previously learned material. The meta-analysis of 26 studies indicated that proactive interference decreased with age. The cross-sectional study found that third through sixth graders' and college students' recall was accurate on Trial 1, but became less so over Trials 2…

This study investigated relations between social interaction during infancy and children's subsequent theory of mind (ToM). Findings indicated that children's performance on ToM tasks at 45 and 48 months positively correlated with mothers' appropriate comments on her infant's mental state, but not with attachment security. Mothers' appropriate…

To assess children's understanding of intentions as distinct from desires, this study presented 3- to 7-year-olds and adults with situations in which intentions were satisfied but desires were not, or vice versa, in a story-comprehension task and target-hitting game. Findings indicated that younger children were unable to differentiate desires and…
