The first part of this paper briefly describes two studies concerned with cognitive processes in children. One study examined the ability of Kindergarten and First Grade children to apply a simple rule of logical inference in order to solve a two-object discrimination problem. Specifically, the rule was of the form "if A, then not B." A second…

Seven main experiments and three pilot studies were conducted to develop and test theories of transfer of training in children. Initial tests failed to support an incentive model for learning and transfer, but a new model given strong emphasis to the role of context in learning was developed which accounted for a wide range of learning and…

Adolescents defined as educable retarded who have demonstrated their ability to profit from experiences (highscorers and gainers) were hypothesized to perform more adequately than nongainers on the Stroop Color-Word interference task. The tasks were administered on three successive days to each subject in the following order: color, word,…

Author stresses the importance of art, music, and literature experiences in the perceptual development of a child. (GB)

In this study, hypothesis probe techniques were used to provide trial-to-trial monitoring of second and third grade children's use of feedback. (SB)

This study investigates the relationship between temporal organization and the rate at which discrimination-reversal learning mastery occurs within sixth-grade students. Subjects were 22 male and 30 female students from a predominantly white, middle class rural school. Temporal behavior was assessed with a task that had subjects reproduce standard…

Simple and complex learning and problem solving situations were employed with mentally retarded children and adults. In the Rotation-Discrimination Complex and the Size-Discrimination Simple experiments, upper and lower test achievement subgroups were subjected to two basic types of visual discrimination at different levels of task complexity.…

Random polygons were used as stimuli in a two-choice multiple discrimination learning paradigm designed to test individual learning ability. A nonverbal test was developed in order to avoid the cultural and racial bias which, according to the author, is inherent in verbal tests. Information processing rate (IPR) was used as the measure of learning…

Six experiments examined the problem-solving behavior of normal and mentally retarded (MR) children with a two-choice discrimination learning situation: the effects of stimulus similarity upon types of solutions utilized by MR children; the role of redundant cues in the discrimination learning of MR subjects with differing mental ages; the…
