The effect of information feedback of movement components on the reaction time (RT) and movement time (MT) of mentally retarded adults performing a discrete movement aiming task was investigated. We anticipated that specific training and informational feedback on the RT portion of the RT-MT task would more effectively reduce RT, despite aiming requirements(More)
Manifest anxiety scores of students receiving part-time services for learning disabilities, students receiving full-time services for learning disabilities, and a matched group of nonexceptional peers were compared. A significant difference was found between the part-time group and the nonexceptional group in Total Anxiety and Worry-Oversensitivity.
Two experiments were conducted to examine the degree to which mentally retarded adults can be trained to improve their reaction time (RT) and movement time (MT). A discrete aiming task that had both RT and MT components was utilized in Experiment 1. Only MT improved significantly across the 15 training days, and this performance level was maintained after 5(More)
The degree to which response complexity affects the ability of moderately mentally retarded adults to perform on a coincident timing task was examined. In Experiment 1 subjects were required to depress a key to estimate accurately the arrival of a moving target at a predetermined coincident point. Analyses of both constant and variable error scores(More)
