Previous research on Montessori preschool education is inconsistent and prone to analytic flexibility. In this preregistered study, disadvantaged preschoolers in a French public school were randomly assigned to either conventional or Montessori classrooms, with the latter being adapted to French public education.

One-quarter of the Head Start population has a mother who participated in the program as a child. This study uses experimental Head Start Impact Study (HSIS) data on 3- and 4-year-olds (N = 2,849) to describe multigenerational Head Start families and their program experiences. In sharp contrast to full-sample HSIS findings, Head Start has large,…

Head Start enhances school readiness during preschool, but effects diminish after children transition into kindergarten. Designed to promote sustained gains, the Research-based Developmentally Informed (REDI) Parent program (REDI-P) provided home visits before and after the kindergarten transition, giving parents evidence-based learning games,…

The neurodevelopmental sequelae of early deprivation were examined by testing (N = 132) 8- and 9-year-old children who had endured prolonged versus brief institutionalized rearing or rearing in the natal family. Behavioral tasks included measures that permit inferences about underlying neural circuitry. Children raised in institutionalized…

Used hierarchical linear modeling to explore the effects of the social context of Chapter 1 prekindergarten classrooms on 4-year-olds' learning. Found that children made smaller gains on the Preschool Inventory over the preschool year in classrooms with higher concentrations of minorities, children with special needs, recent immigrants, and…

An extended longitudinal study compared cognitive development in children adopted from Romania before 24 months and in United Kingdom adoptees with an additional sample of Romanian children adopted after 24 months. Findings indicated that there was considerable catch-up among late-placed Romanian children but they exhibited lower cognitive scores…

The effects of 4 months of gymnostic training upon complex and simple gross motor abilities and general cognitive and psychosocial functioning in 4-year-olds were compared with the effects of music training and no treatment. (WY)

A total of 146 disadvantaged preschool children were trained in 1 of 3 different types of fantasy activities. The effects of this training were evaluated over a variety of tasks measuring cognitive development and impulse control. (Author/JMB)

Gender constancy was assessed at ages 4, 5, 6, and 7 for 314 economically disadvantaged children. Results yielded evidence for the sequential placement of a transitional phase in the development of gender constancy. (JMB)

Young children in poor communities are spending more hours in nonparental care because of policy reforms and expansion of early childhood programs.

Outerdirectedness has been defined by first author and his colleagues as a style of problem solving characterized by reliance on concrete situational cues rather than by active attempts to deduce abstract relationships. (Authors/MB)

Studied the sociocultural context in which Brazilian children acquire and use everyday mathematics in terms of currency use. Participants were 105 children, ages 4 to 11, and their parents. Found decreased use of currency with increasing age. Children also used currency to aid their problem solving and progressed from global estimates to the…

Investigates levels and patterns of intellectual development of 131 socioeconomically disadvantaged children in university-based intervention group day care or community day care, or with little or no day care. Results suggest that high quality day care may positively change the intellectual development of socioeconomically disadvantaged children.…
