Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Investigated relationships between behavioral and cognitive impulsivity in children. Cognitive style was not predicted by classroom behavior, indicating that it may be a relatively independent dimension. (DP)

Fifth-grade boys and girls were administered the Matching Familiar Figures Test and a projective measure of fantasy aggression and its control. They were also rated sociometrically by peers and teachers on physical, verbal, and indirect forms of overt aggression. Results indicated that conceptual tempo was related to aggression and its control.…

Examines the effects of training second grade boys identified as impulsive (on a matching familiar figures test) to use a more analytic approach in processing stimuli. (CM)

Third grade subjects were classified as impulsive or reflective on the basis of the Matching Familiar Figures (MFF) test. In Experiment I, subjects were given either convergent thinking tasks, brainstorming tasks, or a control task. In Experiment II, half of the subjects received difficult tasks intended to induce failure while the other half…

The purpose of this study was to determine whether or not children manifesting different cognitive styles also behave differently in small-group instructional situations. Six groups of seven children each engaged in a small group videotaped learning experience in which they were to learn the English equivalent of 75 symbols. Analysis of the data…

This paper describes a study of the classroom behavior patterns of 79 reflective and impulsive elementary school children in each of three contextual settings: individual setting (independent, unsupervised seat work); large group setting (15 or more students instructed by the teacher or another adult); and small group setting (similar to large…
