Efficient search for an object often requires that attention be prevented from returning to recently examined environmental loci. M. I. Posner and Y. A. Cohen (1984) proposed that inhibition of return (IOR) of visual attention is a search mechanism that prevents such attentional perservation. The internal representations upon which IOR functions were examined and the following conclusions were drawn: First, IOR mechanisms have access to both object- and environment-based representations. Second, environment-based inhibition can be associated with a featureless environmental location, whereas the object-based mechanism requires that attention be oriented to a visible object. These findings are discussed in terms of physiological pathways that may mediate location- and object-based effects.
高效地寻找一个物体通常需要防止注意力返回到最近检查过的环境位置。M. I. 波斯纳和Y. A. 科恩（1984年）提出，视觉注意力的返回抑制（IOR）是一种防止这种注意力持续的搜索机制。研究了IOR发挥作用所依据的内部表征，并得出以下结论：第一，IOR机制可以访问基于物体和基于环境的表征。第二，基于环境的抑制可以与一个没有特征的环境位置相关联，而基于物体的机制则要求注意力指向一个可见物体。根据可能介导基于位置和基于物体效应的生理途径对这些发现进行了讨论。
