Abstract

Impulsivity, although commonly associated with maladaptive behavior, can influence how individuals manage cognitive and motor demands. This study analyzed the effect of impulsivity on motor control and cognitive effort during manual aiming tasks that varied in cognitive load. From an initial sample of 109 volunteers, a final sample of 63 right-handed adults was classified as high or low impulsive based on Brazilian Portuguese version of the Barratt Impulsiveness Scale-11 scores. Participants performed two aiming task conditions with different execution demands, while electroencephalographic workload and engagement indices were recorded to assess cognitive effort. Motor performance was evaluated through accuracy, temporal, kinematic, and inhibitory control measures. Results showed similar motor performance and kinematic patterns between groups. However, the high impulsive group consistently exhibited higher workload indices across both task conditions and made more response inhibition errors under high execution demand. These findings suggest that highly impulsive individuals mobilize greater cognitive resources to sustain motor performance comparable to that of less impulsive individuals. This compensatory increase in effort highlights the interaction between personality traits, cognitive control, and motor behavior.

认知努力作为冲动性运动控制的补偿机制。

冲动虽然通常与适应不良行为有关，但也会影响个人管理认知和运动需求的方式。本研究分析了在不同认知负荷的手动瞄准任务中，冲动性对运动控制和认知努力的影响。从109名志愿者的初始样本中，63名右撇子成年人的最终样本根据巴西葡萄牙版巴拉特冲动性量表-11得分被分为高冲动性和低冲动性。参与者在两种不同的目标任务条件下执行不同的执行要求，同时记录脑电图工作量和参与指数来评估认知努力。通过准确性、时间、运动学和抑制控制措施来评估运动表现。结果显示各组之间的运动性能和运动模式相似。然而，高冲动组在两种任务条件下均表现出较高的工作负荷指数，并且在高执行需求下出现了更多的反应抑制错误。这些发现表明，与冲动较少的人相比，高度冲动的人调动了更多的认知资源来维持运动表现。这种努力的补偿性增加突出了人格特征、认知控制和运动行为之间的相互作用。

期刊介绍： The Journal of Motor Behavior, a multidisciplinary journal of movement neuroscience, publishes articles that contribute to a basic understanding of motor control. Articles from different disciplinary perspectives and levels of analysis are encouraged, including neurophysiological, biomechanical, electrophysiological, psychological, mathematical and physical, and clinical approaches. Applied studies are acceptable only to the extent that they provide a significant contribution to a basic issue in motor control. Of special interest to the journal are those articles that attempt to bridge insights from different disciplinary perspectives to infer processes underlying motor control. Those approaches may embrace postural, locomotive, and manipulative aspects of motor functions, as well as coordination of speech articulators and eye movements. Articles dealing with analytical techniques and mathematical modeling are welcome.
