To-investigate the temporal allocation of attention, a series of 7 experiments using rapid serial visual presentation (RSVP) was designed to examine the relationship of the attentional demands of various target tasks to the production of the subsequent visual attentional deficit, or "attentional blink" (AB), recently reported by J. E. Raymond, K. L. Shapiro, and K. M. Arnell (1992). The principal finding is that AB occurs only when a target is an object and does not occur when the target is defined by a temporal interval. Target detection difficulty as estimated by d' analysis reveals no relationship between the attentional demands of the target and the production of the AB. A late-selection account of this phenomenon is offered in place of the early-selection account advanced in Raymond et al.'s previous report.
为了研究注意力的时间分配,设计了一系列7个使用快速序列视觉呈现(RSVP)的实验,以检验各种目标任务的注意力需求与随后视觉注意力缺陷(即“注意瞬脱”,AB)产生之间的关系,该缺陷最近由J.E.雷蒙德、K.L.夏皮罗和K.M.阿内尔(1992年)报道。主要发现是,只有当目标是一个物体时才会出现注意瞬脱,而当目标由时间间隔定义时则不会出现。通过d'分析估计的目标检测难度表明,目标的注意力需求与注意瞬脱的产生之间没有关系。本文提出了对这一现象的晚期选择解释,以取代雷蒙德等人之前报告中提出的早期选择解释。
