Geometric matrix problems were presented to 11- and 14-year-olds and adults to investigate latency to solution as a function of number of elements (1-3) and of transformations (0-2) that had to be considered for correct solution. At all ages latencies increased as the number of elements and number of transformations increased. (Author/DB)

Examined age differences in the use and effectiveness of social support processes emitted during conversations about real life negative events between preadolescent, adolescent, and adult friends. Participants were 86 same-sex friendship dyads. Results indicated that talking to friends alleviated negative affect in all ages, but factors predicting…

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…

Examined the development of proportional reasoning by means of a temperature mixture task. Results show the importance of distinguishing between intuitive knowledge and formal computational knowledge of proportional concepts. Provides a new perspective on the relation of intuitive and computational knowledge during development. (GLR)

Children's analogical reasoning has traditionally been measured by classical four-term analogy tasks or problem-solving tasks. Current theories of analogical development and the evidence on which they are based are reviewed. It is concluded that structural views of analogical development are wrong, and knowledge-based accounts of what develops are…

Using data from 5,070 youth ages 11 to 18 years old who participated in the National Longitudinal Study of Adolescent Health, concurrent and longitudinal associations among cumulative risk, protective factors, and youth maladjustment were examined. Cumulative risk was associated with concurrent conduct problems and depressed mood. For conduct…

Two studies investigated children's metacognition about everyday reasoning, assessing how they distinguish reasoning from nonreasoning and "good" reasoning from "bad." In Study 1, 80 1st graders (6-7 years), 3rd graders (8-9 years), 5th graders (10-11 years), and adults (18+ years) evaluated scenarios where people (a) used reasoning, (b) solved…

Effective family problem solving was studied in 97 families of elementary-school-aged children with definite- and indefinite-solution tasks. Incentive and task independence were manipulated. It was found that definitions of effective problem solving based on directly observed measures of group interaction were more valid than definitions based on…

Evaluates fourth-to seventh-grade children on two aspects of social cognition: interpersonal understanding and means-ends problem-solving ability. Relates the two variables to sex, age, IQ, social class, and multiple dimensions of competence. Both variables significantly correlated with I.Q. while interpersonal understanding also correlated with…

This study examined variables related to problem-solving approaches of young children, using the theoretical framework provided by Zigler and collaborators in their work on outerdirectedness. Four aspects of outerdirectedness were examined: developmental trends, different types of reinforcement, task difficulty, and pride in accomplishment. (ST)

Implications are that increasing a child's ability to think in terms of alternative solutions to real-life problems could supplement a primary preventive mental health program. (Authors)

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…

Correlated teens' strategies for regulating their attachment to their mothers as measured by the Adult Attachment Interview, and emotion regulation during teen-mother problem solving. Teens with secure strategies engaged in problem-solving discussions characterized by less dysfunctional anger and less avoidance of problem solving than other teens.…

Examined associations between the quality of the interparental relationship and the success of 68 family triads (mother, father, preadolescent son) in solving family problems. Parental agreement on child rearing issues facilitated problem solving, whereas strong parental coalitions inhibited problem solving. The latter result may be attributed to…

Examines developmental patterns in the solution of verbal analogies. Twenty subjects in each of grades 3, 6, 9, and in college were tested on their relative abilities to solve 180 verbal analogies based on five different verbal relations. (CM)
