演講摘要:

Perceiving and producing emotions is one of the quintessential evolutionary utilities that multicellular and complex organisms can employ to enhance survival, not only for themselves but also for members of their conspecies. For humans, faces are perhaps the most powerful and versatile biological platform whereby meaningful and satisfying social interactions are engaged and unfolded. We not only can verify a person’s identity via his or her face, but also can read out numerous kinds of information from the face, such as the person’s intention and attention (gaze), emotional states, and even personality traits, among others. In this talk, I shall discuss two studies investigating a number of factors that may affect and influence how we process emotional expression from faces. In Study 1, using gaze-contingency control, we investigated the effect of perceptual field (PF) size on processing identity and expression of faces. The results suggest the possible existence of a continuum, where at one end, it has a very small PF for processing positive facial expression such as happiness, a larger PF for processing non-positive expressions, and an even larger PF for processing face identity at the other end. In Study 2, using fMRI, we examined the brain mechanisms underlying affective labeling of facial expressions. Specially we looked at the brain regions that are likely involved in converting facial expression images into emotional labels (i.e., image-to-label conversion, ILC). The results suggest that both the rDLFPC and lFFG were activated by ILC. However, whether and how the ACC may be involved in ILC is yet to be clearly investigated in the future research. Together, these studies illustrate how we can take advantage of various research methodologies to unravel the complex nature of how we process emotional expression from faces. Furthermore, findings from these studies may shed light on the theoretical implications of how we should conceptualize emotion, the nature of which is contentiously debated in recent years.
