Effect of dual task interference between motor task and cognitive task

Abstract

This study investigated how dual task interference between a motor task anda cognitive task affected performance on each. The motor task was a tandem standing one,and the cognitive task was the Stroop interference task. Postural sway and the number of correct answers tasks were evaluated for60young healthy subjects. Dual task interference was found to improve performance on the motor task but lower it on the cognitive task performance. This finding indicates that considerable attentional resources are not necessary for high performance on the motor task in a dual task condition.
