P300事件相关电位反映了高水平的认知加工;它对注意力调节也很敏感，阻碍了它在伪装检测中的应用。这是否可以通过特别突出的刺激来克服，例如，动作还是表情方法在11名受试者中，我们运行两个并发的，不相关的oddball序列（“主序列”和“分心序列”）。我们通过三种类型的任务来调节受试者的注意力：（1）计数主要的奇怪的球，（2）被动观看，（3）计数分心的奇怪的球。对于主序列，频繁的刺激是均匀的灰色，和oddballs是（a）固定光栅，（B）移动光栅，或（c）面对。在干扰物序列中，频繁刺激为黑色注视目标，而白色注视目标为奇数。结果人脸的P300波幅大于静止和移动光栅。注意力集中时P300振幅中值最大;在“被动”条件下P300显著降低（光栅降低至30%，面部降低至80%），而“分心”条件下P300降低更多（光栅降低至40%，面部降低至55%）。与分心，显着的P300发生在9 11名受试者的脸，只有在5或4与固定或移动grating，respectively.ConclusionsFace-evoked P300更耐分心比那些固定或移动光栅。这提供了支持的社会认知作用的面孔与特权处理机制。P300的注意调制依赖于刺激类别。面部刺激可能有助于客观地访问更高级别的处理，同时尽量减少故意的影响。
ObjectiveThe P300 event-related potential reflects high-level cognitive processing; it is also sensitive to attentional modulation, impeding its use in malingering detection. Can this be overcome by particularly salient stimuli, e.g., motion or faces?MethodsIn 11 subjects, we ran two concurrent, uncorrelated oddball sequences (“main sequence” and “distractor sequence”). We modulated the subjects’ attention via three types of tasks: (1) count main oddballs, (2) passive viewing, and (3) count distractor oddballs. For the main sequence, the frequent stimulus was homogeneously gray, and oddballs were (a) stationary gratings, (b) moving gratings, or (c) faces. For the distractor sequence, the frequent stimulus was a black fixation target, with a white fixation target as oddball.ResultsP300 amplitudes were larger for faces than for stationary and moving gratings. Median P300 amplitudes were largest when attending; the P300 was substantially reduced in the “passive” condition (down to 30 % for gratings and down to 80 % for faces) and somewhat more for the “distraction” condition (down to 40 % for gratings and down to 55 % for faces). With distraction, significant P300s occurred in 9 of 11 subjects for faces, only in 5 or 4 with stationary or moving gratings, respectively.ConclusionsFace-evoked P300s were more resistant to distraction than those to stationary or moving gratings. This provides support for the socio-cognitive role of faces being associated with privileged processing mechanisms. Attentional modulation of P300 depends on stimulus category. Face stimuli may help to objectively access higher level processing while minimizing willful influences.
