有效地搜索和扫描环境的能力是空间行为的先决条件。一个长期存在的理论(Posner M.I.和Cohen，Y.(1984))。视觉定向的组成部分。在H.Bouma，&D.Bouhuuis(编辑)，注意和表现X(pp.53 1556)。伦敦：Erlbaum)提出，抑制以前参加过的位置(抑制返回；IOR)有助于通过增加检查新区域的可能性而不是返回到以前检查过的位置来促进勘探。在这项眼动研究中，我们测试了我们是否能找到支持这一假设的证据。在这里，我们报告了在搜索和自由观看期间确实发生了IOR，因为我们发现在返回眼跳(返回到先前注视位置的眼球运动)之前，注视时间增加。同时，我们没有观察到IOR对搜索策略的影响。我们发现了许多回跳，而不是预测的较低数量。因此，IOR在扫视搜索和免费观看中不起到觅食促进器的作用。我们假设IOR是转移注意力和凝视方向的一个内在方面，而且它并不总是有利于防止回跳。(C)2005爱思唯尔有限公司。保留所有权利。
The ability to search and scan the environment effectively is a prerequisite for spatial behavior. A longstanding theory (Posner M. I., & Cohen, Y. (1984). Components of visual orienting. In H. Bouma, & D. Bouwhuis (Eds.), Attention and performance X(pp. 53 1556). London: Erlbaum) proposes that inhibition of previously attended loci (Inhibition of return; IOR) serves to facilitate exploration by increasing the likelihood to inspect new areas instead of returning to locations that have been inspected before. In this eye movement study we tested whether we could find evidence in favor of this hypothesis. Here we report that IOR does occur during search and free viewing, because we found increased fixation times preceding return saccades (eye movements that return to previously fixated locations). Meanwhile we observed no influence of IOR on the search strategy. Rather than the predicted low number we found many return saccades. Therefore, IOR does not serve as a foraging facilitator in saccadic search and free viewing. We hypothesize that IOR is an intrinsic aspect of shifting attention and gaze direction and furthermore that it is not always advantageous to prevent return saccades. (c) 2005 Elsevier Ltd.
