奖励预期已被证明可以促进各种认知和行为操作，特别是通过提高与接近奖励相关的过程的速度和活力。这一领域的研究通常采用任务机制，参与者的公开反应受到预期奖励的促进。相反，我们在这里证明，即使是运动反应的取消也可以被奖励预期加速，从而表明奖励相关的好处是限制而不是接近行为。重要的是，这种促进作用独立于与策略相关的反应速度调整而发生，众所周知，这种调整会系统性地扭曲对反应取消速度的估计。动机因素确实可以促进反应抑制，这一事实不仅与理解健康参与者的动机和反应抑制如何相互作用有关，而且与研究各种表现出反应抑制缺陷的患者群体有关，这表明抑制运动反应能力的核心差异必须与动机因素区分开来。(C) 2012 Elsevier B.V.版权所有
Reward prospect has been demonstrated to facilitate various cognitive and behavioral operations, particularly by enhancing the speed and vigor of processes linked to approaching reward. Studies in this domain typically employed task regimes in which participants' overt responses are facilitated by prospective rewards. In contrast, we demonstrate here that even the cancellation of a motor response can be accelerated by reward prospect, thus signifying reward-related benefits on restraint rather than approach behavior. Importantly, this facilitation occurred independent of strategy-related adjustments of response speed, which are known to systematically distort the estimation of response-cancellation speed. The fact that motivational factors can indeed facilitate response inhibition is not only relevant for understanding how motivation and response inhibition interact in healthy participants but also for work on various patient groups that display response-inhibition deficits, suggesting that core differences in the ability to inhibit motor responses have to be differentiated from motivational factors.
