This research explored the contribution of social goal orientation, specifically, development (improving social skills and relationships), demonstration-approach (gaining positive judgments), and demonstration-avoidance (minimizing negative judgments). Children (N = 373; M age = 7.97, SD = 0.34) were followed from 2nd to 3rd grades. Validity of…

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)…

This study examines whether feeding infants formula supplemented with long-chain polyunsaturated fatty acids (LCPUFA) improves cognitive function of 9-month-olds. Participants included 229 infants from 3 randomized controlled trials. Children received either formula supplemented with docosahexaenoic acid and arachidonic acid, or a control formula…

Six experiments examined children's ability to make inferences using temporal order information. Children completed versions of a task involving a toy zoo; one version required reasoning about past events (search task) and the other required reasoning about future events (planning task). Children younger than 5 years failed both the search and the…

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.…

This study examined whether knowledge of arithmetic contributes to difficulties with equations. In Experiment 1, children (ages 7-11) completed tasks to assess their adherence to 3 operational patterns prevalent in arithmetic: (a) the strategy of performing all given operations on all given numbers, (b) the "operations=answer" problem structure,…

Do typical arithmetic problems hinder learning of mathematical equivalence? Second and third graders (7-9 years old; N= 80) received lessons on mathematical equivalence either with or without typical arithmetic problems (e.g., 15 + 13 = 28 vs. 28 = 28, respectively). Children then solved math equivalence problems (e.g., 3 + 9 + 5 = 6 + __),…

Investigates the evidence that the imperfect performance in forward search of 36 children aged four and five years resulted from unstable execution of the correct component processes. Evidence suggests that five-year-olds engaged in forward search, but four-year-olds used only a rudimentary form of forward search. (RJC)

Studied infants' reactions to a Plexiglas box placed over a toy by their mothers. (JMB)

The link between the quality of attachment in infancy and the quality of play and problem-solving behavior at age two years was examined in 48 infants. (Author/JMB)

Investigated the effectiveness of a training procedure corresponding to a component analysis of a hypothesis-testing task in improving kindergarten children's problem-solving abilities. (Author/JMB)

Three experiments were performed in an attempt to integrate ideas and methods developed to study problem solving with those developed specifically to study children's inquiry strategies. (Author/JMB)

Examined the ability of 2 1/2- to 4 1/2-year-olds to recognize and implement strategies for resolving comprehension difficulties. In contrast to previous experimental findings, results indicate that young children are capable of detecting a variety of comprehension problems and possess appropriate strategies for resolving these difficulties with a…

Investigated the ability of preschool and early grade school children to use logical search strategies to find a missing object on a familiar playground. Results indicated that children of all ages studied could deduce a critical search area and were not guided primarily by strong spatial associations. (Author/DB)

Investigated the effects of caregiving experience on adults' thinking about a child-rearing problem. Study 1 found that, of 192 adults, parents were better than nonparents at diagnosing the cause of a baby's crying. Study 2 extended the first study's findings to 42 mothers and 42 nonmothers. (SKC)
