Stimuli that reach the sensory surface may result in perception, or serve to guide action. How are these two potential consequences of sensory stimulation related? I discuss three aspects of this problem. The conceptual aspect concerns the status of the concept of perception in an objective psychology. The methodological aspect pertains to the problem of how psychophysics is related to the assessment of performance measures. The functional aspect relates to the function(s) of perception for action control. I argue that (a) conceptually, the term perception belongs to a different level of description than the constructs of information-processing models: (b) methodologically, psychophysical judgements and performance measures are not necessarily converging operations: (c) functionally, sensory information can be used for the control of action without perception as a mediating stage (direct parameter specification). Taken together, this suggests that perception should be conceptualized not as a processing stage, but as a class of actions that serve to establish and update an internal representation of the environment.
到达感觉表面的刺激可能会导致感知，或用于指导行动。感觉刺激的这两种潜在结果是如何相关的呢？我将讨论这个问题的三个方面。概念方面涉及感知概念在客观心理学中的地位。方法方面涉及心理物理学与绩效指标评估如何相关的问题。功能方面涉及感知对行动控制的功能。我认为：（a）从概念上讲，“感知”一词属于与信息处理模型的构建不同的描述层次；（b）从方法上讲，心理物理学判断和绩效指标不一定是趋同的操作；（c）从功能上讲，感觉信息可用于在没有感知作为中介阶段的情况下控制行动（直接参数指定）。综合起来，这表明感知不应被概念化为一个处理阶段，而应被概念化为一类用于建立和更新环境内部表征的行动。
