A long-standing debate revolves around which mental codes allow humans to control behavior. The internal stimulus model (going back to Rudolf Hermann Lotze) proposes that behavior is controlled by codes of stimuli that had previously preceded corresponding motor activities. The internal effect model (going back to Emil Harleß) proposes that behavior is controlled by codes of perceptual effects that had previously resulted from corresponding motor activities. Here, we present a test of these two control models. We observed evidence for both models with stronger evidence for the internal stimulus model. We suggest that the proposed experimental setup might be a useful tool to study the relative strengths of stimulus control and effect control of behavior in various contexts.

长期争论围绕着哪些心理代码允许人类控制行为展开。内部刺激模型（回到 Rudolf Hermann Lotze）提出行为是由先前在相应运动活动之前的刺激代码控制的。内部效应模型（回到 Emil Harleß）提出，行为是由先前由相应运动活动产生的知觉效应代码控制的。在这里，我们对这两种控制模型进行了测试。我们观察到两种模型的证据，内部刺激模型的证据更强。我们建议，所提出的实验设置可能是研究各种环境下刺激控制和行为效果控制的相对强度的有用工具。
