研究表明，在并发任务下，自然场景的无注意力语义处理不会损害类别检测（例如，F. Li， R. VanRullen， C. Koch, & P. Perona, 2002）。这种能力是否反映了析取特征集的检测，而不是高级绑定？参与者在快速连续视觉呈现（RSVP）序列中检测到一个动物目标，然后报告其身份和位置。他们经常不能识别或定位他们正确检测到的目标，这表明检测只是基于部分处理。在包含人类的序列中，目标的检测要差得多，可能是因为它们有共同的特征。当在RSVP中同时出现两个目标时，会出现一个长时间的注意眨眼，当两个目标都被发现而不被识别时，这个眨眼几乎被消除。结果表明，快速特征分析介导检测，然后是需要注意的绑定，以识别和定位。
Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial visual presentation (RSVP) sequence and then reported its identity and location. They frequently failed to identify or to localize targets that they had correctly detected, suggesting that detection was based only on partial processing. Detection of targets was considerably worse in sequences that also contained humans, presumably because of shared features. When 2 targets were presented in RSVP, a prolonged attentional blink appeared that was almost eliminated when both targets were detected without being identified. The results suggest rapid feature analysis mediating detection, followed by attention-demanding binding for identification and localization.
