Abstract
Cognitive strategies underlying excellent performance of intelligent people on the Raven's Progressive Matrices Test were used to develop a teaching package. 24 subjects in a Cognitive Strategies group were trained using this teaching package. An Exposure group of 17 subjects were not trained but solved all the examples of puzzles in the package. A Control group, with 13 subjects, received no intervention. Subjects were pre- and posttested on matrix solving ability and were posttested on a Piagetian multiplicative classification task. The Cognitive Strategies group showed the greatest improvement pre- to posttest, followed by the Exposure group and then the Control group. The Cognitive Strategies group was superior to both controls on the Piagetian task, indicating a broad improvement in cognitive functioning.
