The ability to inhibit an ongoing action in response to a signal from the environment is important for many perceptual-motor actions. This paper examines a particular example of this behavior: attempting to inhibit or "check" a swing in baseball batting. A model of motor inhibition in batting is proposed. In the model there are three different inhibition signals (out of range launch angle, early expected-actual trajectory discrepancy, and late expected-actual trajectory discrepancy) resulting in four possible response outcomes for the batter's swing (full swing, inhibited swing, partial response, or interrupted swing). The predictions of the model were compared with the actual batting performance of 20 baseball players using a high-fidelity batting simulator. The proportions of the different response outcomes could be explained by the inhibition model for 17/20 of the batters in the study. These findings suggest that models of motor inhibition developed for simple, discrete tasks can be applied to complex, multistage behaviors. This batting inhibition model could be used to provide a quantitative measure of a player's bat control for training and player-screening purposes.

响应来自环境的信号抑制正在进行的动作的能力，对于许多感知运动行为来说都很重要。本文研究了这种行为的一个具体例子：在棒球击球中试图抑制或“检查”挥棒动作。提出了一个击球运动抑制模型。在该模型中，有三种不同的抑制信号（超出范围的发射角度、早期预期-实际轨迹差异和晚期预期-实际轨迹差异），这导致击球手挥棒有四种可能的反应结果（全力挥棒、抑制挥棒、部分反应或中断挥棒）。使用高保真击球模拟器，将该模型的预测与20名棒球运动员的实际击球表现进行了比较。对于研究中的17/20的击球手，不同反应结果的比例可以由抑制模型来解释。这些发现表明，为简单、离散任务开发的运动抑制模型可以应用于复杂的多阶段行为。这种击球抑制模型可用于为训练和球员筛选目的提供球员击球控制的定量测量。（PsycINFO数据库记录（c）2009美国心理学会，保留所有权利）
