Abstract

The purpose of the present study was to examine the role of cognitive conflict demands made by reaction time (RT) tasks that cause decrements in the performance of children with physical awkwardness. Both children with physical awkwardness (AWK; n=10; mean age 6 years 2 months) and control group children without physical awkwardness (CON; n=10; mean age 6 years 1 month) responded selectively to a target arrow that had flanking compatible or incompatible "noise" arrows. In a simple reaction time task, 4 stimuli were randomly mixed, and participants were to push a single button to respond; in a choice reaction time task, 9 stimuli were used, and participants pushed either the left or the right button. Children with physical awkwardness demonstrated significantly longer reaction times and a greater number of errors on both tasks than did the children without physical awkwardness. However, poor motor performance that results from cognitive conflict is not a specific characteristic of children with physical awkwardness.
