在视觉领域中定位对象的能力是至少三个混合过程的协作：扫描多个位置，识别所寻求的对象（目标），并在没有找到目标的情况下结束搜索。使用分布分析，可以评估终止的概率取决于检查的地点数量。结果表明，在一些没有目标的试验中，被试进行了比显示器中有物体更多的比较;在其他条件下，他们进行了比物体更少的比较。因为错误很少，所以过早的止损并不是纯粹的猜测。我们提出的模型来解释这些发现。终端的分布有助于确定响应时间与集大小相关的函数的斜率。
The ability to locate an object in the visual field is a collaboration of at least three intermingled processes: scanning multiple locations, recognizing the object sought (the target), and ending the search in cases when the target is not found. In this paper, we focus on the termination rule. Using distribution analyses, it is possible to assess the probability of termination conditional on the number of locations examined. The results show that on some trials without target, the participants carried out more comparisons than there are objects in the display; in other conditions, they carried out fewer comparisons than objects. Because there were very few errors, the premature stops were not pure guesses. We present models to account for these findings. The distributions of terminations help determine the slopes of the functions relating response time to set size.
