Are Happy Faces Attractive? The Roles of Early vs. Late Processing.

Sun D, Chan CC, Fan J, Wu Y, Lee TM - Front Psychol (2015)

Bottom Line: Facial attractiveness is closely related to romantic love.We found that attractiveness and expression were reflected by two early components, P2-lateral (P2l) and P2-medial (P2m), respectively; their interaction effect was reflected by LPP, a late component.The findings suggested that facial attractiveness and expression are first processed in parallel for discrimination between stimuli.

ABSTRACT
Facial attractiveness is closely related to romantic love. To understand if the neural underpinnings of perceived facial attractiveness and facial expression are similar constructs, we recorded neural signals using an event-related potential (ERP) methodology for 20 participants who were viewing faces with varied attractiveness and expressions. We found that attractiveness and expression were reflected by two early components, P2-lateral (P2l) and P2-medial (P2m), respectively; their interaction effect was reflected by LPP, a late component. The findings suggested that facial attractiveness and expression are first processed in parallel for discrimination between stimuli. After the initial processing, more attentional resources are allocated to the faces with the most positive or most negative valence in both the attractiveness and expression dimensions. The findings contribute to the theoretical model of face perception.

Source reconstruction results for the effects of level of attractiveness and level of expression and their interaction in each time window of interest. For observation purposes, results are height-thresholded at p < 0.05 with cluster size > 150 voxels. FFA, fusiform area; MTG, middle temporal gyrus; Para, parahippocampal gyrus; TP, temporal pole.

Figure 6: Source reconstruction results for the effects of level of attractiveness and level of expression and their interaction in each time window of interest. For observation purposes, results are height-thresholded at p < 0.05 with cluster size > 150 voxels. FFA, fusiform area; MTG, middle temporal gyrus; Para, parahippocampal gyrus; TP, temporal pole.

Mentions: For the Level of Attractiveness effect, significant activities were detected in sites that coincided with locations in the bilateral parahippocampal gyri within the 150–200 ms and 220–260 ms periods (Figure 6). Another significant site was identified in the right fusiform gyrus within the 825–900 ms period. For the Level of Expression effect, significant activities were detected at the site that coincided with the bilateral middle temporal gyri within the 150–305 ms and 365–450 ms periods. A few more sites were identified, with one detected in the right fusiform gyrus within the 365–450 ms period and another in the bilateral fusiform gyri and the left temporal gyri within the 725–780 ms period. For the interaction between Level of Attractiveness and Level of Expression, significant activities were detected in the site that coincided with the bilateral temporal poles within the 450–725 ms period.
