背景资料：心理测量学、解剖学和大脑功能研究表明，个体在感知和分析信息以及策略性地控制和执行动作的方式上存在差异。个体间的差异也被观察到在特定和一般认知能力的神经相关。因此，一些人感知和适应环境条件，并比其他人更好地进行运动活动。本研究的目的是确定一个共同的因素，预测适应的一个达到运动的视觉干扰和抑制运动相关的大脑活动（亩节奏）。结果：28名参与者参加了两个不同的实验，旨在评估视觉适应和亩抑制能力。采用修订的韦氏成人智力量表（Wechsler Adult Intelligence Scale）评定操作智商（IQ）。操作智商预测视觉操作的适应指数（r=0.43，p=0.02）和mu节律的抑制（r = -0.59; p < 0.001）。高性能IQ的参与者更快地适应视觉干扰，更好地抑制mu活动比低性能IQ的参与者。结论：我们发现性能IQ和mu抑制之间可能存在联系，性能IQ和初始适应率。具有高性能IQ的个体在抑制mu节律方面更好，并且比具有低性能IQ的个体更快地将运动命令和所需运动相关联（C）2015 Elsevier B.

Background: Psychometric, anatomical and functional brain studies suggest that individuals differ in the way that they perceive and analyze information and strategically control and execute movements. Inter-individual differences are also observed in neural correlates of specific and general cognitive ability. As a result, some individuals perceive and adapt to environmental conditions and perform motor activities better than others. The aim of this study was to identify a common factor that predicts adaptation of a reaching movement to a visual perturbation and suppression of movement-related brain activity (mu rhythms).Results: Twenty-eight participants participated in two different experiments designed to evaluate visuomotor adaptation and mu suppression ability. Performance intelligence quotient (IQ) was assessed using the revised Wechsler Adult Intelligence Scale. Performance IQ predicted adaptation index of visuomotor performance (r=0.43, p=0.02) and suppression of mu rhythms (r = -0.59; p < 0.001). Participants with high performance IQ were faster at adapting to a visuomotor perturbation and better at suppressing mu activity than participants with low performance IQ.Conclusions: We found a possible link between performance IQ and mu suppression, and performance IQ and the initial rate of adaptation. Individuals with high performance IQ were better in suppressing mu rhythms and were quicker at associating motor command and required movement than individuals with low performance IQ (C) 2015 Elsevier B.V.
