Two experiments tested infants' sensitivity to properties of point-light displays of a walker and a runner that were equivalent regarding the phasing of limb movements. Found that 3-, but not 5-month-olds, discriminated these displays. When the symmetrical phase-patterning of the runner display was perturbed by advancing two of its limbs by 25…

Examined whether the quality and content of everyday parent-child conversations about negative emotions differed from everyday talk about positive emotions. Found that children and parents talked about past emotions, causes of emotions, and connections between emotions and other mental states at higher rates during conversations about negative…

Provided 2- and 2.5-year-olds with partial visual information about a ball's path as it moved toward a hiding place. Found that both age groups were equally proficient at tracking the ball as it rolled behind a transparent screen with 4 opaque doors, but 2.5-year-olds were more likely to reach to the correct door when asked to find the ball.…

Data from a 25-year study of 194 individuals indicated that teacher and peer reports of aggression, compliance, and self-control at age 8 distinguished high-agreeable from low-agreeable 33-year-olds. High-agreeable childhood types had fewer disobedience and concentration problems than low-agreeable childhood types. High-agreeable childhood boys…

Used point-light displays (lights corresponding to the joints of the human body) to examine 3-year-olds' understanding of verbs. Found that children could extend familiar motion verbs (walking, dancing) to videotaped point-light actions shown in an intermodal preferential looking paradigm. Children watched the action matching the requested verb…

Used meta-analysis to examine relationship of parents' gender schemas and their offspring's gender-related cognitions, with samples ranging in age from infancy through early adulthood. Found a small but meaningful effect size (r=.16) indicating a positive correlation between parent gender schema and offspring measures. Effect sizes were influenced…

Examined effects of interfering information and instructions to forget on preschoolers' and kindergartners' story retention. Found that retroactive interference affected preschoolers' storage- and retrieval-based forgetting rates and kindergartners' storage-based forgetting rates. Intentional forgetting reduced retroactive interference primarily…

Three studies investigated development of beliefs about dreams among preschoolers, elementary school children, and adults. Results revealed significant changes between 3- and 5-years about the role of behavioral experiences and mental processes in generation of dream content. There was significant development in beliefs that dreams are not subject…

Examined effects of the pubertal transition on behavior problems and its interaction with family and neighborhood circumstances in 10- to 12-year-old African Americans. Found that early-maturing youth living in disadvantaged neighborhoods were more likely to affiliate with deviant peers. Early-maturing youth experiencing harsh, inconsistent…

Examined whether the social organization of problem solving of Guatemalan Mayan indigenous mothers and children varied with the mothers' school experience. Found that mothers with little schooling were involved more in horizontal, multiparty engagements while solving a puzzle with three children, whereas mothers with extensive schooling were…

Examined maternal care and infant attachment security in a sample from the United States (Colorado) and one from Colombia. Found that maternal sensitivity and infant security were significantly associated in both samples. Identified six common and two noncommon domains (one per sample) of caregiving; associations between domains of maternal…

Examined impact of shame and attributional style on adjustment following sexual abuse. Found that once adjustment at discovery was accounted for, shame and attribution style explained additional variation in adjustment 1 year later; abuse severity did not. Relations between abuse severity and subsequent depressive symptoms and self-esteem were…

Explored relation of biological and psychosocial risk factors to infant development among pregnant women who had pregestational diabetes, gestational diabetes, or were nondiabetic. Found that infants of diabetic mothers scored lower on the Bayley Scales at 1 year and revealed fewer positive and more negative behaviors than infants of nondiabetic…

Two experiments examined toddlers' ability to use cues to infer meaning of novel action words. Toddlers were taught labels for similar or dissimilar pairs of videotaped actions, with behavioral cues or eye gaze related to agents' intentions distinguishing similar events. Results showed that in year 2, children begin to consider…

Examined effects of contextual and individual differences on mothers' autonomy support versus control on homework-like tasks with their third-grade children. Found that mothers in the high-pressure condition were more controlling on the poem task. For the map task, mothers with initial controlling styles in the high-pressure condition were more…
