Movement Difficulty and Learning Disabled Children
Results of recent research have implicated information processing deficits in explaining the poor academic performance of learning disabled children. However, the motor difficulties of these children have not been extensively studied from a processing framework, yet cognitive skills are inherent to the successful performance of motor skills. Sixteen learning disabled and sixteen control subjects ranging in age from 6 to 8 years were tested on a Fitts’ reciprocal tapping task using 16 different target combinations with the ID ranging from 1.50 to 6.64 bits. Analysis of the slope and intercept coefficients showed a significant difference for intercept but not for slope. These data suggest that the problem may not be a major processing deficit, as the learning disabled children were able to handle the increased task difficulty in the same manner as the controls. Instead the problem may exist at the very early input stage of the processing mechanism: getting the information into the system.
