In an attempt to clarify the findings of Neisser and his associates with respect to parallel processing of multiple target items in a visual search task, subjects were tested in a multiple-target search situation in which the various target sets were not nested. 20 sessions were run for each subject with 12 trials per day. The targets used were geometric forms, allowing for manipulation of the number of features in each form. The results do not confirm those of Neisser, in fact, the interaction of session x target-set size was in a direction opposite to that predicted by a parallel preattentive processing may in fact have reflected a tendency for subjects to scan for a master set of targets, regardless of which subset of that set was actually present on a given set.
为了阐明奈塞尔及其同事在视觉搜索任务中对多个目标项目进行并行处理的研究结果，我们让受试者在各种目标集不嵌套的多目标搜索情境中接受测试。每位受试者进行了20次测试，每天进行12次试验。所使用的目标是几何图形，这样可以控制每个图形中的特征数量。结果并未证实奈塞尔的研究结果，事实上，测试次数与目标集大小之间的交互作用方向与并行前注意加工所预测的方向相反，这实际上可能反映了受试者扫描一组主要目标的倾向，而不管该组中的哪个子集实际出现在给定的集合中。
