摘要:
Real-world threatening faces possess both useful and irrelevant attributes with respect to the current goal. How these attributes interact and affect attention, which comprises at least three processes hypothesized to engage the frontal lobes (alerting, orienting, and executive control), remains poorly understood. Here, the neurocognitive effects of threatening facial expressions on the three processes of attention were examined through the emotional Attention Network Test (ANT) and functional near-infrared spectroscopy (fNIRS). Forty-seven (20M, 27F) young adults performed a blocked version of the arrow flanker task with neutral and angry facial cues applied in three cue conditions (no, center, and spatial). Hemodynamic changes occurring in participants' frontal cortices during task performance were recorded by multichannel fNIRS. Behavioral results indicated that alerting, orienting, and executive control processes existed in both the neutral and angry conditions. However, depending on the context, angry facial cues affected these processes differently compared with neutral facial cues. Specifically, the angry face disrupted the classical decrease in reaction time from the no-cue to center-cue condition specifically during the congruent condition. Additionally, fNIRS results revealed significant frontal cortical activation during the incongruent vs. congruent task; neither cue nor emotion significantly affected frontal activation. Thus, the findings suggest that the angry face affects all three attentional processes while exerting context-specific effects on attention. They also imply that during the ANT, the frontal cortex is most involved in executive control. The present study offers essential insights into how various attributes of threatening faces interact and alter attention.
