We present two experiments that test the range of applicability of a movement planning model (MEGaMove) based on statistical decision theory. Subjects attempted to earn money by rapidly touching a green target region on a computer screen while avoiding nearby red penalty regions. In two experiments we varied the magnitudes of penalties, the degree of overlap of target and penalty regions, and the number of penalty regions. Overall, subjects acted so as to maximize gain in a wide variety of stimulus configurations, in good agreement with predictions of the model.
我们展示了两个实验，这些实验测试了基于统计决策理论的运动规划模型（MEGaMove）的适用范围。受试者试图通过快速触摸计算机屏幕上的绿色目标区域来赚钱，同时避开附近的红色惩罚区域。在两个实验中，我们改变了惩罚的大小、目标区域与惩罚区域的重叠程度以及惩罚区域的数量。总体而言，受试者的行为是为了在各种刺激配置下实现收益最大化，这与模型的预测高度一致。
