两个实验研究了如何利用视觉搜索任务中非目标项的信息来控制搜索。第一个实验使用“障碍”刺激的检测来证明上下文项目的有效记忆表征可以在每个特定的试验中建立。这一发现可以用上下文信息短期整合模型来解释。第二个实验改变了局部而不是全局上下文的复杂性，提供了有关所涉及的集成操作性质的一些信息。在其最终版本中，该模型假定加工的两个阶段具有独立的整合机制。第一阶段的空间整合删除小样本内的重复。第二阶段的时间整合在更大的间隔内存储和启动上下文项的记忆表示。假设试验内的短暂时间整合与试验之间的永久时间整合是由相同的机制介导的。
Two experiments studied how information about the nontarget items in a visual search task is used for the control of the search. The first experiment used the detection of “hurdle” stimuli to demonstrate that efficient memory representations of the context items can be established within each particular trial. This finding is explained by a model for the short-term integration of context information. The second experiment which varied the complexity of the local but not the global context provided some information about the nature of the integration operations involved. In its final version the model postulates two stages of processing with independent mechanisms of integration. Spatial integration at the first stage deletes repetitions within small samples. Temporal integration at the second stage stores and primes the memory representations of the context items over larger intervals. It is assumed that transient temporal integration within trials is mediated by the same mechanism that underlies permanent temporal integration between trials.
