Siblings' imitative behaviors were investigated in 39 middle-class dyads during six 90-min home sessions at both Time 1 (M age: older sibling = 4.4 years; younger sibling = 2.4 years) and Time 2 (2 years later). Although younger siblings imitated most often at T1 and T2, older siblings' imitation increased proportionally over time in comparison to…

Amid growing controversy about the oft-cited "30-million-word gap," this investigation uses language data from five American communities across the socioeconomic spectrum to test, for the first time, Hart and Risley's (1995) claim that poor children hear 30 million fewer words than their middle-class counterparts during the early years…

A half century of research details how segregating racial groups in separate schools corresponds with disparities in funding and quality teachers and culturally narrow curricula. But we know little about whether young Latino children have entered less or more segregated elementary schools over the past generation. This article details the growing…

Students from low-income families consistently trail behind their peers in retention and degree attainment. Research on college student experiences suggests that low-income students experience "cultural mismatch" at college--they feel that their backgrounds are at odds with the middle-class values dominant on campus (Armstrong &…

What role do children play in education and stratification? Are they merely passive recipients of unequal opportunities that schools and parents create for them? Or do they actively shape their own opportunities? Through a longitudinal, ethnographic study of one socioeconomically diverse, public elementary school, I show that children's…

This longitudinal study examined the relationship between pedagogical continuity in literacy education and early literacy development by comparing Chinese children in Hong Kong and Shenzhen. Stratified random sampling was used to select 24 preschool and Primary 1 classes in four communities catering to middle-class families in each city. The 24…

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother-infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and…

This study examined Black-White differences in growth of depressive affect using a longitudinal sample of middle-class, suburban U.S. subjects (n = 956) that spanned from adolescence to early adulthood. Specifically, this study examined whether Black-White differences in growth of depressive affect shift over time, and the extent to which that…

Background: Researchers have largely attributed achievement gaps between different groups of students in the United States to differences in resources, parent education, socioeconomic status (SES), and school quality. They have also shown how, through their "cultural productions," certain students may disadvantage themselves. Focus: This article…

Number sense development of 411 middle- and low-income kindergartners (mean age 5-8 years) was examined over 4 time points while controlling for gender, age, and reading skill. Although low-income children performed significantly worse than middle-income children at the end of kindergarten on all tasks, both groups progressed at about the same…

The School Mathematics Study Group of Stanford University is conducting a 4-year longitudinal study of mathematical learning in the primary grades. The purpose of this paper is to present the results of this study for the kindergarten year. Approximately 2,000 kindergarten children from two large cities were divided into lower and middle income…

THIS ARTICLE PRESENTS SIZE AND GROWTH VELOCITY DATA COLLECTED DURING A LONGITUDINAL STUDY OF 111 NORMAL, HEALTHY NEGRO INFANTS FROM LOWER-MIDDLE-CLASS FAMILIES. DATA WERE OBTAINED FROM BIRTH RECORDS AND MEASUREMENTS TAKEN DURING ROUTINE PHYSICAL EXAMINATIONS. WHEN THIS NEGRO SAMPLE WAS COMPARED WITH WHITE INFANTS IN SIMILAR STUDIES IT WAS FOUND…

Examined longitudinally conceptions of parental authority and ratings of parental rules and decision-making among middle- class African American adolescents and their parents. Found that nearly all subjects affirmed parents' legitimate authority to regulate and children's obligation to comply regarding oral, conventional, prudential, friendship,…
