预览效应是一种在已经存在的多个旧客体中优先选择多个新客体,对新客体表现出优先加工的现象。文章综述了预览效应认知神经机制的两种主要观点：（1）旧客体抑制观点,认为预览效应是由于对旧客体的抑制;（2）新客体突现捕获注意观点,认为预览效应是由于新客体出现伴随着亮度突然增加捕获注意。这两种观点之间的主要争论在于：预览效应与新旧客体亮度变化的关系;新旧客体的颜色关系是否影响对目标的搜索;在一些因素的作用下,旧客体形状变化是否还会破坏预览效应。文章指出,预览效应是旧客体抑制机制与新客体突现捕获注意机制共同作用的结果。

Preview benefit refers to prioritize the selection of new items among distracters that have been presented early. The current paper reviews cognitive neural mechanisms of preview benefit. The inhibition of old items account attributes preview benefit to the suppression of the old items, while the attention capture by new onsets account argues that preview benefit is associated with the attention capture by the luminance onsets of the new items. Recent studies have tried to tackle this theoretical controversy in three perspectives： first, they investigate the relationship between preview benefit and the luminance changes of old and new items; second, they determine whether preview benefit can be affected by the relationship between the color of old and new items;third, they explore the boundary conditions that immunize preview benefit from the changing of old items’ shape. This paper suggests that both inhibition of old items and attention capture by new onsets contribute to preview benefit.
