In an investigation of search strategies, it was predicted that reflective children would have developmentally more mature problem-solving strategies than impulsive children, and the presence of these strategies would be found in both 6- and 8-year-old subjects. From a sample given the Matching Familiar Figures Test, half of the 20 boys and 20 girls at each age level were classified as reflective and half as impulsive. Subjects were then administered a marble game task patterned after a 3-choice probability learning task. Strategies of guessing patterns were recorded. Analyses of the several possible task strategies substantiated the study's hypotheses with the 6-year-old sample, but not with the 8-year-old sample. The lack of significant findings with the older group was attributed to task inappropriateness for the 8-year level. (Author/MS)
