The study assessed task performance of 25 hyperactive and 22 normal children (six to ten years old) with and without within-task color, holding task complexity constant. (Author)

Examines rapid-tapping performance of 36 hyperkinetic and 36 control boys under conditions of free response, verbal urging, and penny rewards. Hyperkinetics were unable to adjust to changing incentive conditions. (Author/EK)

These data support the notion that amount of maternal involvement in task solution is determined partly by task difficulty and the child's ability to complete the tasks presented. (Author)

Eight seven- and eight-year-old hyperactive children were assigned to either a self-instructional training group or an attention practice control group. On-task behavior in the classroom and performance measures in reading and arithmetic were assessed. (Author/SBH)

To investigate the effects of distraction, task performance with or without within-task color, holding task complexity constant, was assessed with 25 hyperactive Ss and 22 controls (5 to 10 years old). Two visual-motor drawing tasks, one visual concentration task and a combined visual-motor and visual concentration task were given. Error analyses…

This research investigated temporal ordering acuity in children, or the ability to perceive the first of an ordered pair of lights, or of a combined light and tone, when the interstimulus time interval within each pair became increasingly short in duration. Two group-related comparisons were made: (1) differences between slow-maturing and average…
