Examined the relationship between individual interactional style, individual problem-solving behavior, and family problem-solving effectiveness in 431 intact rural families with 2 children, 1 of whom was in seventh grade. Results indicated that a hostile interactional style directly predicted destructive problem-solving behavior, whereas a warm…

In a study of the use of baserates and the representativeness heuristic, children and college students made judgments about scenarios that varied by domain and information provided. The use of baserates and heuristic, and the consistency between subjects' choices and rationales, increased with age. Use of individuating information developed early.…

Examines the dynamics involved when preschoolers aged five years attempt to build replicas of Lego models, either by working alone or with another. Results show that collaboration was more conducive to learning than was independent work and that children were able to generalize their skills. (Author/RWB)

The family-management skills of parents of seventh- and tenth-grade boys were related to each of two criterion measures of delinquency: police contacts and self-reported delinquency. The measures of parent monitoring and discipline were shown to correlate significantly with both criterion measures. (Author/RH)

Uni- and multidimensional processing of 6- to 9-year olds was studied using recall tasks in which an array of stimuli was reconstructed to match a model array. Results indicated that both age groups were able to solve multidimensional problems, but that solution rate was retarded by the unidimensional processing of highly salient dimensions.…

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…

Results indicated that Piagetian developmental level significantly predicted problem-solving performance, whereas level of field independence did not appear to clarify individual differences in a meaningful way. (Author)

In the first experiment, 16 kindergarten children were tested on vertical/horizontal and oblique discriminations in symmetrical and asymmetrical alignments. When stimuli were asymmetrically aligned, the former discrimination was learned as rapidly as the latter. The second experiment demonstrated that the influence of configurational cues in…

Second- and sixth-grade boys were paired with a friend or an acquaintance (N=120), and each dyad completed a problem-solving task under cooperative, competitive, or no reward contingencies. Communicative exchange, affective expression, synchrony of task-oriented behavior, and task performance were examined for evidence of purported mutuality in…

In a series of experiments, young children were asked to compare the quantities of classes of objects under two conditions: (1) when one of the classes of objects is a subordinate of the other (the traditional class-inclusion problem), and (2) when the terms refer to exclusive sets but different levels of generality. (Author/RH)

Subjects were eight first-graders with older siblings, half from 2-child families and half from larger families. The four sex combinations of sibling pairs were equally represented. Half the children were aided on the task by their mother; half were aided by their sibling. Comparisons were made by sex and family size. nAuthor/JH)

Investigated whether fourth-graders' gestures convey knowledge self-recognizable in another context. Identified math problem-solving procedures conveyed gesturally and examined whether the procedures could be accessed by the same child on a task not involving gesture. Children rated higher those solutions derived from procedures they conveyed…
