In her article, Michaels (2000) defined action as "a temporally bounded, observable, goal-directed movement (or non-movement) that entails intention, the detection of information, and a lawful relation between that information and the movement" (p. 251). She defined perception as "the detection of information" (p. 244). This forces one to conclude that it is impossible to study action separately from perception. We argue that perceptual judgments are communicated by movements and that it is impossible to distinguish movements reporting perceptual judgments from other movements, so we conclude that the reverse also is true: It is impossible to study perception separately from action.
