It has been suggested that the human brain processes visual information in different manners, depending on whether the information is used for perception or for action control. This distinction has been criticized for the lack of behavioral dissociations that unambiguously support the proposed two-visual-pathways model. Here we present a new and simple dissociation between vision for perception and vision for action: Perceptual judgments are affected by the similarity of relevant and irrelevant stimulus features, while object-oriented actions are not. This dissociation overcomes the methodological problems of previously proposed differences in terms of vulnerability to visual illusions or to variability in irrelevant object features, and it can also serve as an easily applicable behavioral indicator of underlying processing modes.
有人认为，人类大脑会根据信息是用于感知还是用于动作控制，以不同的方式处理视觉信息。这种区分因缺乏明确支持所提出的两条视觉通路模型的行为差异而受到批评。在这里，我们提出了一种新的、简单的感知和动作视觉之间的分离：感知判断受到相关和不相关刺激特征相似性的影响，而面向对象的动作不受影响。这种分离克服了以前提出的差异在易受视觉错觉或无关物体特征变化影响方面的方法学问题，也可以作为一种易于应用的行为指标，用于潜在的处理模式。
