Positive youth development programs such as those offered by Boy Scouts of America (BSA) provide sources of support and opportunities for leadership and character development. Programmatic experts from BSA collaborated with researchers to develop a visual theory of change (pathway model) for youth development in Scouts BSA and for adult volunteer…

The present investigation examined the sexual dimorphic patterns of cardiorespiratory fitness to working memory in preadolescent children (age range: 7.7-10.9). Data were collected in three separate studies (Study 1: n = 97, 42 females; Study 2: n = 95, 45 females; Study 3: n = 84, 37 females). All participants completed a cardiorespiratory…

This study evaluated effects of "Positive Action," a school-based social-emotional and character development intervention, on indicators of positive youth development (PYD) among a sample of low-income, ethnic minority youth attending 14 urban schools. The study used a matched-pair, cluster-randomized controlled design at the school…

The rate at which people process information appears to influence many aspects of cognition across the lifespan. However, many commonly accepted measures of "processing speed" may require goal maintenance, manipulation of information in working memory, and decision-making, blurring the distinction between processing speed and executive…

The present longitudinal study tested the roles of early childhood executive control (EC) as well as exposure to poverty-related adversity at family and school levels as key predictors of low-income children's EC in elementary school ("n" = 391). Findings suggest that children's EC difficulties in preschool and lower family income from…

Performing action has been found to have a greater impact on learning than observing action. Here we ask whether a particular type of action--the gestures that accompany talk--affect learning in a comparable way. We gave 158 6-year-old children instruction in a mental transformation task. Half the children were asked to produce a "Move"…

Prenatal exposures to neurotoxins and postnatal parenting practices have been shown to independently predict variations in the cognitive development and emotional-behavioral well-being of infants and children. We examined the independent contributions of prenatal cigarette exposure and infant learning stimulation, as well as their…

This study used a mixed methods methodology to investigate the reliability and validity of the Ounce Scale, an authentic, observational assessment of infants' and toddlers' development from birth through 42 months of age. Quantitative cross-sectional data were collected from 287 children and 124 teachers in seven urban Early Head Start programs;…

This study examined whether parental involvement in children's science schoolwork (i.e., discussions about science, homework helping and encouragement of science interest) varies for boys and girls, and how these behaviors relate to children's science achievement beliefs (i.e., ability perceptions and task-value) at the end of a school year. We…

The present study investigated the association of mothers' marriage and changes in young adolescents' cognitive and socioemotional development and changes in family processes. Analyses employed longitudinal data from the "Three-City Study" to track maternal partnerships for 860 low-income adolescents (10-14 years-old in Wave 1) across a…

Publicly funded prekindergartens are programs that most states use to promote school readiness, especially of 4-year-old children at risk for academic problems due to poverty. Despite large public expenditures, these programs have not been widely evaluated. We examined 240 randomly selected pre-kindergarten programs in six states with mature…

The question of how youth become engaged or motivated is vital to youth development programs, because engagement influences not only program retention but the likelihood of youth gaining the benefits that programs offer. This article reports on an in-depth study aimed at generating grounded theory about the change process through which youth who…
