Separate cognitive processes govern the inhibitory control of manual and oculomotor movements. Despite this fundamental distinction, little is known about how these inhibitory control processes relate to more complex domains of behavioral functioning. This study sought to determine how these inhibitory control mechanisms relate to broadly defined domains of impulsive behavior. Thirty adults with attention-deficit/hyperactivity disorder (ADHD) and 28 comparison adults performed behavioral measures of inhibitory control and completed impulsivity inventories. Results suggest that oculomotor inhibitory control, but not manual inhibitory control, is related to specific domains of self-reported impulsivity. This finding was limited to the ADHD group; no significant relations between inhibitory control and impulsivity were found in comparison adults. These results highlight the heterogeneity of inhibitory control processes and their differential relations to different facets of impulsivity.
不同的认知过程支配着手动和眼动运动的抑制控制。尽管存在这一基本区别，但对于这些抑制控制过程如何与更复杂的行为功能领域相关联，我们却知之甚少。本研究旨在确定这些抑制控制机制如何与广义定义的冲动行为领域相关联。30名患有注意力缺陷多动障碍（ADHD）的成年人和28名对照成年人进行了抑制控制的行为测量，并完成了冲动性量表。结果表明，眼动抑制控制而非手动抑制控制与自我报告的冲动性特定领域相关。这一发现仅限于ADHD组；在对照成年人中未发现抑制控制与冲动性之间存在显著关系。这些结果突出了抑制控制过程的异质性及其与冲动性不同方面的差异关系。
