The attentional blink (AB) is a well-established phenomenon in the study of attention. This deficit in reporting the second of two targets presented in rapid serial visual presentation when it occurs 200-500 ms after the first is considered to reflect a fundamental limitation in attentional processing. However, we recently reported that some individuals do not show an AB, and presented psychophysiological evidence that target processing differs between blinkers and non-blinkers. One possibility is that non-blinkers may have a larger WM capacity, allowing better attentional control. Here we explore the relation between the magnitude of the AB, general intelligence, and different measures of working memory (WM) and short-term memory (STM) capacity. Surprisingly, no correlation was found between memory capacity measures and AB magnitude, raising doubts about the generalizability of earlier findings of such a relationship.
注意瞬脱(AB)是注意力研究中一个已被充分证实的现象。当在快速序列视觉呈现中呈现的两个目标中的第二个目标在第一个目标出现后200 - 500毫秒出现时,报告第二个目标的这种缺陷被认为反映了注意力加工的一个基本限制。然而,我们最近报告称,一些个体并未表现出注意瞬脱,并提供了心理生理学证据表明,出现注意瞬脱者和未出现者之间的目标加工存在差异。一种可能性是,未出现注意瞬脱者可能具有更大的工作记忆容量,从而能实现更好的注意力控制。在此,我们探讨注意瞬脱程度、一般智力以及工作记忆(WM)和短期记忆(STM)容量的不同测量指标之间的关系。令人惊讶的是,我们并未发现记忆容量测量指标与注意瞬脱程度之间存在相关性,这引发了人们对早期关于这种关系的研究结果可推广性的质疑。
