(A) Dual-task cost: dual-task cost=(single-task–dual-task)/single-task×100. Dual-task cost was measured with the total number of shapes matched. Independent t test results show higher dual-task cost indicates greater cognitive-motor interference. Children with HCP (n=9) had higher dual-task cost than TD children (n=12). (B) Correlations between PFC activation and dual-task cost: scatter plot of the PFC activation while performing dual-task condition and dual-task cost in children with HCP (n=9). Abscissa represents average HbO concentration and the ordinate represents percentage of dual-task cost. Pearson correlation analysis shows a strong positive correlation (r= 0.77, P=.01) in children with HCP, which suggests that children who had greater PFC activation tended to have greater cost of performing a dual task.
