本研究考察了缺乏眼白混淆因素的人类凝视是否可以无意识地加工，并探讨了这一过程的关键方面。利用连续的闪光抑制范式，一个示意图的脸——直视或回避的目光，中性，恐惧或快乐的表情——被呈现在一只眼睛面前，而动态面具使它对另一只眼睛不可见。使用图式脸来避免明显的眼白带来的不必要的影响。参与者对面具以外的任何东西的检测时间被用作无意识处理时间的指标。人们发现，直视人脸的识别速度要快于目光转移的人脸。然而，不同面部表情（实验1）和正脸、倒脸和只看眼睛（实验2）的检测时间没有差异。这些结果证实，对于图式面孔，凝视可以在无意识的情况下被处理，而不考虑面部表情，而眼睛本身就足以完成这一过程。(C) 2012爱思唯尔公司版权所有。
This study examines whether human gaze lacking the confounding factor of eye whites can be processed unconsciously and explores the critical aspects for such process. Utilizing the continuous flash suppression paradigm, a schematic face-with direct or averted gaze, and with neutral, fearful or happy expressions-was presented to one eye while dynamic masks rendered it invisible to the other eye. Schematic faces were used to avoid unwanted influence from salient eye whites. Participants' detection time of anything other than the masks was used as an index of unconscious processing time. Faster detection was found for faces with direct gaze than those with averted gaze. However, there was no difference between detection times for different facial expressions (Experiment 1) and upright-face, inverted-face, and eyes-only conditions (Experiment 2). These results confirm that, with schematic faces, gaze can be processed unconsciously regardless of facial expression, and eyes alone are sufficient for such process. (C) 2012 Elsevier Inc.
