The effects of 2 weeks of no, general, and task-related enhanced movement experiences on 8- to 12-week-old infants' (N=30) hand and foot interactions with objects were assessed using standard video and motion analysis. For hand object interaction ability, general and task experience led to greater success than did no experience, and task…

Effects of prenatal cocaine exposure and parental versus nonparental care on outcome at 2 years of age were examined. The sample included 83 cocaine-exposed and 63 nonexposed children and their caregivers; 49 and 34 of the cocaine-exposed children experienced parental and nonparental care, respectively. Prenatal drug exposure was not related…

This study investigated the contributions of 5 mechanisms to the effects of preschool participation in the Child-Parent Centers for 1,404 low-income children in the Chicago Longitudinal Study. Based on a matched-group design, preschool participation was associated with significantly higher rates of educational attainment and lower rates of…

This study examined the extent to which continuities and discontinuities in cognitive performance between ages 5 and 10 predicted adult income, educational success, household worklessness, criminality, teen parenthood, smoking, and depression. Assessed were the degree of this change during middle childhood, the influence of socioeconomic status…

For children whose everyday speech differs greatly from the School English (SE) they encounter in academic materials and settings, it was hypothesized that greater familiarity with SE would be associated with more successful early reading acquisition. Sentence imitation and reading skills of 217 urban African American students in kindergarten…

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N=245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level…

A computerized test of preparedness for effortful processing (alerting attention), response to orienting cues (orienting attention), and response to the interference of competing demands (executive attention) was administered to a diverse sample of 249 children (47% female, 4.96 to 7.27 years) to assess developmental properties and…

Young children often have a preference for auditory input, with auditory input often overshadowing visual input. The current research investigated the developmental trajectory and factors underlying these effects with 137 infants, 132 four-year-olds, and 89 adults. Auditory preference reverses with age: Infants demonstrated an auditory preference,…

Differences in basic memory processes between maltreated and nonmaltreated children were examined in an experiment in which middle-socioeconomic-status (SES; N=60), low-SES maltreated (N=48), and low-SES nonmaltreated (N=51) children (ages 57, 89, and 10-12 years) studied 12 Deese-Roediger-McDermott lists. Using recall and recognition measures,…

The development of decision-making autonomy was examined in 76 middle-class African American early adolescents (M=13 years) and their mothers, who were followed longitudinally for 5 years. Adolescent decision-making autonomy over conventional, prudential, multifaceted, and personal issues increased over time but at different rates. Mothers viewed…

Home visiting programs for families with young children have been in effect for many years; however, this is the first comprehensive meta-analytic effort to quantify the usefulness of home visits as a strategy for helping families across a range of outcomes. Sixty home visiting programs contributed data to analysis within 5 child and 5 parent…

This study examined the impact of differential-maternal parenting behavior, evaluated as a family-level experience, on children's emotional-behavioral problems. Data come from 3 child development studies: 2,128 four- to sixteen-year-olds (Ontario Child Health Study), 7,392 four- to eleven-year-olds (National Longitudinal Study of Children and…

Links between early and late emerging inhibitory characteristics of young children are poorly understood. Based on existing evidence, this study proposed an indirect link between reactive inhibition to novelty (fearfulness) and later emerging effortful inhibition of prepotent response tendencies. A model was tested that posits that fearful…

A longitudinal model of parent academic involvement, behavioral problems, achievement, and aspirations was examined for 463 adolescents, followed from 7th (approximately 12 years old) through 11th (approximately 16 years old) grades. Parent academic involvement in 7th grade was negatively related to 8th-grade behavioral problems and positively…

In 4 experiments 120 three-to four-year-old non readers were asked the identity of a symbolic representation as it appeared with different objects. Consistent with Bialystok (2000), many children judged the identity of written words to vary according to the object with which they appeared but few made such errors with recognizable pictures.…
