Franconeri和Simons(2003)报告说，模拟的隐约物体(以尺寸增加为标志)吸引了人们的注意，而模拟的后退物体(以尺寸减小为标志)则没有。这一发现受到了挑战，因为有证据表明，后退的物体在维度深度移动时可以吸引人们的注意。在目前的研究中，我们比较了隐约可见或后退的物体的影响。两个实验的结果表明，根据搜索斜率的判断，这两种运动类型都受益于注意力优先顺序，而隐约可见的物体引起的反应时间(M)更短。我们的结论是，这两种运动类型在搜索过程中都会引起注意；然而，隐约运动的反应时优势似乎反映了一种发生在选择之外的加工增强，并且是基于运动方向来授予的。
Franconeri and Simons (2003) reported that simulated looming objects (marked by a size increase) captured attention, whereas simulated receding objects (marked by a size decrease) did not. This finding has been challenged with the demonstration that receding objects can capture attention when they move in dime-dimensional depth. In the present study, we compared the effects of objects that either loomed or receded in depth. The results of two experiments showed that whereas both motion types benefited from attentional prioritization, as judged by their search slopes, looming objects elicited shorter response times (M). We conclude that both motion types attract attention during search; however, the RT advantage for looming motion seems to reflect a processing enhancement that occurs outside of selection and is conferred on the basis of motion direction.
