Correlation between impulsivity dimensions and the control in a motor timing task

Abstract

Little is known about the role of the attentional, motor and non-planning impulsivities in motor timing tasks. The aim of this study was to correlate the motor performance in a motor timing task with the performance in neuropsychological tests of twenty two volunteers. Before the execution of the motor task, participant wore a headphone and heard five times each temporal reference (2,500 and 3,500 msec) that consisted of two “bips”. After, the motor timing task was performed in five trials of each temporal reference. The task consisted in transporting tennis balls in a pre-defined sequence in each criterion time. It was evaluated: reaction time, movement time, constant error and absolute error. The neuropsychological tests IGT and CPT-II were applied to the evaluation of impulsivities. The findings indicated that attentional impulsivity was more related to the motor performance than the motor and non- planning impulsivities.
