To examine the relationship between response accuracy and tempo, as measured by the Matching Familiar Figures Test (MFF) and criterion measures, 233 7-, 9-, and 11-year-olds were given the MFF, two problem-solving tasks, and a test of academic achievement. (Author/JH)

Third and fourth grade boys classified as impulsive, reflective, fast/accurate and slow/inaccurate responded to matching tasks varying in the number of dimensions involved. Reflective children performed better on the task with fewer dimensions, while impulsive children were better on the task with many dimensions. (JKS)

This study investigated the hypothesis that there is a developmental trend toward greater flexibility of strategies in visual selection. Subjects were 48 second and sixth graders. (Author/SDH)

Presents an investigation of the hypothesis that an increase in the salience of the total class dimension should improve class-inclusion performance. Subjects were 220 children in kindergarten through third grades. (SDH)

This study explores three areas of learning hierarchies: (1) the condition for learning in accordance with learning hierarchies; (2) the use of hierarchies in the diagnosis and learning of prerequisite intellectual skills; and (3) the conditions of learning and retention of principles. There were seven studies undertaken using elementary and…

It may be concluded that reflective and fast-accurate Ss differ from impulsive Ss of the same grade in the strategies used to solve problems. These strategy differences may or may not lead to more efficient performance, depending on the structure of the task, but they are indicative of different levels of cognitive development. (Author)

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.…

A significant positive correlation between multiple classification was found, in testing 65 children aged 6 to 8 years, at the stage of concrete operations. This is interpreted as support for the existence of a structure d'ensemble of operational schemes in the period of concrete operations. (Authors)

It was shown that hierarchies change with development and that relative salience of a dimension is negatively associated with both reaction time of choice and number of errors on the identity task. (Authors)

This study tests the following hypotheses: (a) the ability to solve disjunctive concepts increases with age; (b) positive instances are of greater use in solving conjunctive concepts while negative instances are of greater use in solving disjunctive concepts; (c) older children will show greater improvement than younger children in concept…

The study compared the performance of severe and mild learning disabled children to normal children on a problem-solving task. The three types of children were assessed on the Matching Familiar Figures task. Results indicated that on the MFF, LD children, as a group, were more impulsive than normal children. (Author)

Three studies of elementary school children's problem-solving procedures in intentional discrimination tasks are reported. Subjects were children selected from kindergarten and grades 2, 3, and 6. (Author/MP)

Investigates the effect of various strategy-modeling techniques on the performance of both young children and elderly adults on the 20 Question Task. (Author/MP)
