It has become widely accepted that the direction of another individual's eye gaze induces rapid, automatic, attentional orienting, due to it being such a vital cue as to where in our environment we should attend. This automatic orienting has also been associated with the directional-arrow cues used in studies of spatial attention. Here, we present evidence that the response-time cueing effects reported for spatially non-predictive gaze and arrow cues are not the result of rapid, automatic shifts of attention. For both cue types, response-time effects were observed only for long-duration cue and target stimuli that overlapped temporally, were largest when the cues were presented simultaneously with the response-relevant target, and were driven by a slowing of responses for invalidly cued targets rather than speeding for validly cued ones. These results argue against automatic attention-orienting accounts and support a novel spatial-incongruency explanation for a whole class of rapid behavioral cueing effects.
由于他人的目光注视方向是关于我们应该关注环境中何处的至关重要的线索,因此它会引发快速、自动的注意力定向,这一点已被广泛接受。这种自动定向也与空间注意力研究中使用的方向箭头线索相关。在这里,我们提供证据表明,针对空间上非预测性的注视和箭头线索所报告的反应时提示效应并非快速、自动的注意力转移的结果。对于这两种线索类型,仅在长时间的线索和时间上重叠的目标刺激中观察到反应时效应,当线索与与反应相关的目标同时呈现时效应最大,并且是由无效线索提示的目标的反应减慢而非有效线索提示的目标的反应加快所驱动。这些结果反对自动注意力定向的解释,并支持对一类快速行为提示效应的新颖的空间不一致性解释。
