It was long believed that central arrows needed to be spatially predictive to produce a shift in spatial attention. Recent evidence indicates, however, that central spatially nonpredictive directional cues, like arrows, will trigger reflexive shifts in attention. We asked what this recent discovery means for past studies that used predictive directional cues such as arrows. Our findings indicate that predictive arrows produce attention effects that greatly exceed the individual or summed effects of reflexive orienting to nonpredictive arrows and volitional orienting to predictive numbers. This suggests that the especially large effect produced by predictive arrows reflects an interaction between reflexive and volitional orienting. Given the broad application of the predictive arrow cueing paradigm in both past and current research, the present data shed new light on a wide range of investigations, from psychophysical studies of basic attention to behavioural and neuroimaging studies of cognition and social development.

:长期以来,人们一直认为中心箭头需要具有空间预测性,才能引起空间注意力的转移。但是,最近的证据表明,中心的空间非预测性方向提示(如箭头)将触发注意力的反思性转变。我们问到最近的发现对于使用预测性方向提示(例如箭头)的以往研究意味着什么。我们的发现表明,预测箭头产生的注意力效应大大超过反射性指向非预测性箭头和自愿性指向预测性数字的个体或合计效果。这表明预测箭头所产生的特别大的效果反映了反射性和自愿性定向之间的相互作用。鉴于预测性箭头提示范例在过去和当前的研究中得到了广泛的应用,目前的数据为从基本关注的心理物理学研究到认知和社会发展的行为和神经影像研究等广泛的研究提供了新的思路。
