Brief Communication 177 The dissociation between perception and action in the Ebbinghaus

According to a recently proposed distinction [1] manipulated. The effect of the displays on perceived size was consistent with the well-known properties of relative-between vision for perception and vision for action, visually guided movements should be largely size contrast illusions; targets surrounded by smaller ob-jects appear to be larger than identical targets surroundedimmune to the perceptually compelling changes in size produced by pictorial illusions. Tests of this by larger objects. Grasp scaling, in contrast, appeared to be affected primarily by the physical proximity of the 2-Dprediction that use the Ebbinghaus illusion have revealed only small effects of the illusion on grasp illusory elements to the target, irrespective of the size of the surrounding elements. Thus, the three illusory dis-scaling as compared to its effect on perception [2±4]. Nevertheless, some have argued that the small plays affected both perception and action, but they did so in quite different ways.effect on grasp implies that there is a single representation of size for both perception and action [5]. Recent findings, however, suggest that the 2-D An analysis of variance (ANOVA) examining the within-pictorial elements, such as those comprising illusory subject variables of task, display, and disk size producedbackgrounds, can sometimes be treated as a significant interaction between the task and illusoryobstacles and thereby influence the programming o
