当受试者被要求确定快速移动的刺激进入窗口的位置时，他们通常不会将刺激定位在边缘，而是定位在该窗口内较晚的位置(Fröhlich效应)。我们报告了五个探索这种错觉的实验。假设刺激进入窗口后，注意力开始向它转移，则对注意力的描述进行测试。当这种转变正在进行时，刺激措施进入了窗口期。由于刺激的第一个现象(即，明确可报告的)表示将在焦点转移结束之前不可用，因此刺激在稍后的某个位置被感知。在实验1中，我们建立了Fröhlich效应，并表明它的大小取决于刺激参数，如移动速度和移动方向。在实验2和实验3中，我们考察了眼动的影响，并测试了当刺激呈现在结构背景中或从不同的偏心开始时，效果是否会发生变化。在实验4和实验5中，我们检验了来自注意模型的特定预测：在实验4中，我们表明移动刺激的处理受益于指示随后移动的开始位置的前一外周线索，这导致初步的焦点转移到移动刺激将出现的位置。其结果是，弗罗利希效应减弱了。使用实验5中的检测任务，我们发现，当运动刺激落入注意转移的临界区间时，关于运动刺激的特征信息就会丢失。总而言之，目前的注意解释表明，选择机制并不完全基于空间；相反，它们可以建立一种也用于知觉判断的空间表征--也就是说，选择机制也可以用于空间建立。
When subjects are asked to determine where a fast-moving stimulus enters a window, they typically do not localize the stimulus at the edge, but at some later position within that window (Fröhlich effect). We report five experiments that explored this illusion. An attentional account is tested, assuming that the entrance of the stimulus in the window initiates a focus shift toward it. While this shift is under way, the stimulus moves into the window. Because the first phenomenal (i.e., explicitly reportable) representation of the stimulus will not be available before the end of the focus shift, the stimulus is perceived at some later position. In Experiment 1, we established the Fröhlich effect and showed that its size depends on stimulus parameters such as movement speed and movement direction. In Experiments 2 and 3, we examined the influence of eye movements and tested whether the effect changed when the stimuli were presented within a structural background or when they started from different eccentricities. In Experiments 4 and 5, specific predictions from the attentional model were tested: In Experiment 4 we showed that the processing of the moving stimulus benefits from a preceding peripheral cue indicating the starting position of the subsequent movement, which induces a preliminary focus shift to the position where the moving stimulus would appear. As a consequence the Fröhlich effect was reduced. Using a detection task in Experiment 5, we showed that feature information about the moving stimulus is lost when it falls into the critical interval of the attention shift. In conclusion, the present attentional account shows that selection mechanisms are not exclusively space based; rather, they can establish a spatial representation that is also used for perceptual judgment—that is, selection mechanisms can bespace establishing as well.
