摘　　要： 如果先呈现若干分心物,然后添加靶子与其他分心物,那么就会改善搜索——预搜索效应。对于过滤分心物的潜在机制,研究者相继提出了主动抑制说、突然呈现说与时间分离说等理论。这些理论都有其合理的一面,能解释一些特定的实验现象,但任何单一机制都无法解释所有的实验现象。文章提出,未来的研究应该整合已有的实验现象与理论,系统考察旧客体与新客体的作用,重点整合抑制说与突现说,它们可能是一个连续体的两端。 Search can be facilitated by presenting one set of distractors before the second set of distractors and the target： the preview effect. The underlying mechanisms allowing the search to be restricted to the new objects were primarily explored in this preview search paradigm. A few theories had been postulated, such as the active inhibition account, the abrupt onset account, and the temporal segregation account. These theories emphasized different aspects of the phenomenon, however, any single mechanism failed to explain all phenomena. This article proposed that the future research should integrate all the existent experimental phenomena and theories, further investigate the roles of old and new objects in preview search, and mainly coordinate the active inhibition account with the abrupt onset account, which might be two sides in a continuum.
