This study used a machine learning framework in conjunction with a large battery of measures from 9,718 school-age children (ages 9-11) from the Adolescent Brain Cognitive Development[superscript SM] (ABCD) Study to identify factors associated with fluid cognitive functioning (FCF), or the capacity to learn, solve problems, and adapt to novel…

A prevailing theory of mathematical problem solving predicts that children will be less accurate solving a + b = c + __ problems versus a + b = __ + c. However, this has never been tested directly. Because of low base rates, information combined from multiple studies can help improve estimation accuracy and precision. This study compared…

Children ask questions and learn from the responses they receive; however, little is known about how children learn from listening to others ask questions. Five experiments examined preschoolers' ("N" = 179) ability to solve simple problems using information gathered from listening to question-and-answer exchanges between 2 parties present in the…

This study examined whether children’s difficulties with stage-salient tasks served as an explanatory mechanism in the pathway between their insecurity in the interparental relationship and their disruptive behavior problems. Using a multimethod, multi-informant design, 201 two-year-old children and their mothers participated in 3 annual…

This study examined parent-child emotion discourse, children's independent social information processing, and social skills outcomes in 146 families of 8-year-olds with and without developmental delays. Children's emergent social-cognitive understanding (internal state understanding, perspective taking, and causal reasoning and problem solving)…

Forty-four Head Start classrooms were randomly assigned to enriched intervention (Head Start REDI--Research-based, Developmentally Informed) or "usual practice" conditions. The intervention involved brief lessons, "hands-on" extension activities, and specific teaching strategies linked empirically with the promotion of: (a)…

Skin conductance level reactivity (SCLR) was examined as a moderator of the association between harsh parenting and child externalizing behavior. Participants were 251 boys and girls (8-9 years). Mothers and fathers provided reports of harsh parenting and their children's externalizing behavior; children also provided reports of harsh parenting.…

Examines the effect of different training methods on perceptual learning of impulsive children. A matching to sample method (M), and a differentiation method (D) were used. Data indicated that Ss receiving D training learned to process features distinguishing stimuli; whereas, Ss receiving M training showed no preference for a particular mode of…

Investigated how children's decisions about allocating money to story characters were affected by the relationship (friends versus strangers) among the characters. Children's rationales for their decisions showed that equality was the most salient principle for decisions at all ages and that older children provided rationales based on benevolence…

To investigate the development of function concepts and their relation to mathematical and logical abilities typically acquired during the age period of five to seven years, children were tested on nonnumerical function tasks, numerical tasks, and aspects of logical reasoning. (PCB)

Focused on (1) the effect of mother-child interaction during a problem-solving task on subsequent, independent child performance; and (2) the variability in the division of task responsibilities and maternal regulation of the child as a function of task difficulty, child age, and task component. Participants were 60 three to five year olds and…

Two classrooms of first graders (N=40) were administered Damon's moral judgment measure, Shure and Spivack's social problem solving measure, and the Stanford-Binet vocabulary. Concurrently, two observers in the children's school environment recorded incidences of successful resolutions of interactions, amount of derogation, and the number of times…

Describes five studies in which the learning and transfer abilities of two- and four-year-old children were examined on a task that required them to combine two separately learned solutions to reach a goal. (HOD)

Examined children's mathematical competencies between ages 7 and 9. Found no differences in developmental rate between children with math difficulties only (MD), math and reading difficulties (MD-RD), reading difficulties only (RD), and normal math/reading achievement (NA). Found that at end of Grade 3, MD group performed better than MD-RD group…
