“…Horgan (10) used an electronic rotary pursuit task with supplementary visual, auditory, or tactile feedback with 119 mildly retarded subjects. In general, supplementary sensory feedback associated with correct response behavior facilitated learning.…”

We tested the following groups for visual pursuit abilities: 54 mentally retarded, 46 cerebral-palsied, and 131 learning-disabled children, 3 to 10 years of age. The resulting five behavioral scores, six directions, and total scores were analyzed for age trends. Comparisons were made between the handicapped groups and between the handicapped and normative samples. The scores were also correlated with other visual and postural abilities. All three handicapped groups scored lower than the normative group and also showed patterns different from the normative group and different from each other. The learning-disabled group most closely approximated the normative group's development patterns. Educational data were not able to be used, and we suggest that future research examine the correlations (both in handicapped and nonhandicapped children) of ocular pursuits and educational achievement, and also obtain more complete data on cerebral-palsied children. Therapists may find the visual pursuits test useful particularly when they want to evaluate a number of aspects of ocular pursuit functioning or when they desire more precision than what is usually available by simple observation.

“…Demura and Nagasawa (1994b) reported that controlled force exertion of young subjects 19 to 27 yr. old is stable over three trials. Horgan (1980) also reported that mildly retarded children acquired a pursuit task under supplementary feedback conditions. It can be inferred from these results that, like the control subjects, for the developmentally delayed subjects the possibility of improving the control of the nerve-muscle system (adaptability to a task and a practice effect) is low after only a few trials.…”

Present purposes were to examine the characteristics of controlled force exertion in 28 developmentally delayed young people (14 men, 14 women), and sex differences compared to 28 normal young students (14 men, 14 women). The subjects matched their submaximal grip strength to changing demand values displayed in a bar chart on the display of a personal computer. The total sum of the differences between the demand value and grip exertion value for 25 sec. was used as an evaluation parameter for the test. The controlled force exertion was significantly poorer for he developmentally delayed group than for controls, and there were large individual differences. The developmentally delayed men scored poorer than women in coordination. Like the controls, the means between trials did not decrease significantly. For these developmentally delayed subjects, performance did not improve after only a few trials. The controlled force-exertion test is useful as a voluntary movement-function test for developmentally delayed subjects.

In order to improve motor performance, mental imagery procedures have evolved over the years with nondisabled subjects. Studies researching the concept of using mental imagery with special populations (Surburg, & Stumpner, 1987; Surburg, 1991; Surburg, Porretta, & Sutlive, 1995) are very few in number. This study examined the efficacy of using mental imagery in developing skill on a motorically oriented task (pursuit rotor) and a cognitively oriented task (peg board) on middle school students with mild mental disabilities (MMD). Thirty subjects were assigned randomly to a physical, imagery, or no-practice control group to perform either a peg board or pursuit rotor task. For each motor task, there was a pretest followed by appropriate treatment regime and a posttest session. The dependent variables were the number of pegs placed in appropriate order for the peg board task and time on target for the pursuit rotor task. Results were that imagery practice enhanced the motor performance of children with MMD on both the peg board (cognitively oriented task) and pursuit rotor (motorically oriented task).
