Early mathematics knowledge is a strong predictor of later academic achievement, but children from low-income families enter school with weak mathematics knowledge. An early math trajectories model is proposed and evaluated within a longitudinal study of 517 low-income American children from ages 4 to 11. This model includes a broad range of math…

This study examined factors that predicted children's gender intergroup attitudes at age 5 and the implications of these attitudes for intergroup behavior. Ethnically diverse children from low-income backgrounds (N = 246; Mexican-, Chinese-, Dominican-, and African American) were assessed at ages 4 and 5. On average, children reported positive…

Guided by family risk and allostasis theoretical frameworks, the present study utilized a prospective longitudinal design to examine associations among family risk experiences, basal cortisol patterns, and cognitive functioning in children. The sample included 201 low-income children living within a midsize city in the Northeastern United States.…

Using an epidemiological sample (N = 1,117) and a prospective longitudinal design, this study tested the direct and indirect effects of preverbal and verbal communication (15 months to 3 years) on executive function (EF) at age 4 years. Results indicated that whereas gestures (15 months), as well as language (2 and 3 years), were correlated with…

Using a representative sample of low-income, primarily minority adolescents (N=647, aged 10-14 years at Wave 1), this study examined bidirectional longitudinal relations between nonresident father involvement, defined as contact and responsibility for children's care and behavior, and adolescent engagement in delinquent activities. Autoregressive…

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…

Collected time-use diaries of television viewing from two cohorts of children (ages 2-5 and 4-7) from low-income families and gave annual tests of reading, math, receptive vocabulary, and school readiness. Found that viewing of child-audience informative programs between ages 2 and 3 predicted higher academic performance. Frequent viewers of…

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…

Among low-income women, Black teenage and White adult mothers' social ties to significant others were found to influence parenting skill. Black adult mothers' parenting skill was predicted only by locus of control. (RH)

Examined association between infants' emotional reactivity and reliance on mother and cognitive and language development at 2 years. Found that infants with high reactivity and reliance on mother during emotion challenges had higher cognitive and language skills than infants with low reactivity and reliance. Poor developmental outcomes were…

Three aspects of racial-ethnic identity (REI)--feeling connected to one's racial-ethnic group (Connectedness), being aware that others may not value the in-group (Awareness of Racism), and feeling that one's in-group is characterized by academic attainment (Embedded Achievement)--were hypothesized to promote academic achievement. Youth randomly…

Examined dimensions and patterns of parenting among 193 low-income African American single mothers with preschoolers. Identified four parenting patterns (aggravated but nurturant, cognitively stimulating, patient and nurturant, and low nurturance). Found that maternal well-being and sociodemographic characteristics accounted for 93 percent of…
