A central question in perception is how stimuli are selected for access to awareness. This study investigated the impact of emotional meaning on detection of faces using the attention blink paradigm. Experiment 1 showed that fearful faces were detected more frequently than neutral faces, and Experiment 2 revealed preferential detection of fearful faces compared with happy faces. To rule out image artifacts as a cause for these results, Experiment 3 manipulated the emotional meaning of neutral faces through fear conditioning and showed a selective increase in detection of conditioned faces. These results extend previous reports of preferential detection of emotional words or schematic objects and suggest that fear conditioning can modulate detection of formerly neutral stimuli.
知觉中的一个核心问题是如何选择刺激以进入意识层面。本研究使用注意瞬脱范式，调查了情绪意义对面孔检测的影响。实验1表明，恐惧面孔比中性面孔被检测到的频率更高，实验2则显示，与快乐面孔相比，恐惧面孔的检测具有优先性。为了排除图像伪迹作为这些结果的原因，实验3通过恐惧条件作用操纵中性面孔的情绪意义，并显示条件化面孔的检测有选择性增加。这些结果扩展了先前关于情绪词汇或示意性物体优先检测的报告，并表明恐惧条件作用可以调节对先前中性刺激的检测。
