人类神经科学领域的一个长期争论围绕着这样一个问题,即与无人值守的刺激相比,有人值守的刺激是否会被更快地处理。我们进行了两个事件相关电位(ERP)的实验,采用时间顺序判断程序,以评估是否无意识的注意加速感觉处理,早期视觉ERP组件的潜伏期调制所示。一个不可报告的外源性线索可以在相同(兼容)或相反(不兼容)的位置以相等的概率先于第一个目标。使用不可报告的线索促进自动的,自下而上的注意力捕获,并确保消除任何混淆相关的使用刺激功能,是共同的线索和目标。行为结果证实了无意识的线索无意识的外源定向。ERP结果表明,N1PC,注意力定向的电生理措施,是较小的,达到峰值的兼容性,而不是不兼容的试验,表明线索依赖性的变化的幅度和速度的第一目标处理在纹外视觉区。补充贝叶斯分析证实了这种效应的存在,无论参与者是否积极寻找线索(实验1)或不通知它(实验2),表明纯粹自动的,刺激驱动的定向机制。
A long-standing controversy in the field of human neuroscience has revolved around the question whether attended stimuli are processed more rapidly compared to unattended stimuli. We conducted two event-related potential (ERP) experiments employing a temporal order judgment procedure in order to assess whether involuntary attention accelerates sensory processing, as indicated by latency modulations of early visual ERP components. A non-reportable exogenous cue could precede the first target with equal probability at the same (compatible) or opposite (incompatible) location. The use of non-reportable cues promoted automatic, bottom-up attentional capture, and ensured the elimination of any confounds related to the use of stimulus features that are common to both cue and target. Behavioral results confirmed involuntary exogenous orienting towards the unaware cue. ERP results showed that the N1pc, an electrophysiological measure of attentional orienting, was smaller and peaked earlier in compatible as opposed to incompatible trials, indicating cue-dependent changes in magnitude and speed of first target processing in extrastriate visual areas. Complementary Bayesian analysis confirmed the presence of this effect regardless of whether participants were actively looking for the cue (Experiment 1) or were not informed of it (Experiment 2), indicating purely automatic, stimulus-driven orienting mechanisms.
