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.

Double dissociation between level of attractiveness and level of expression. (A) Main effect of Level of Attractiveness after excluding the effects of Level of Expression. Waveforms in channel 20 at left occipital-temporal sites showed clear differences for different levels of Attractiveness (reflected by P2l) but not for different levels of Expression. (B) Main effect of Level of Expression after excluding the effects of Level of Attractiveness. Waveforms in channel 72 at medial parietal sites showed clear differences among different levels of Expression (reflected by P2m) but not for different levels of Attractiveness. A1, attractive; A2, less attractive; UA2, less unattractive; UA1, unattractive; H1, happy; H2, less happy; S2, less sad; S1, sad.

Figure 4: Double dissociation between level of attractiveness and level of expression. (A) Main effect of Level of Attractiveness after excluding the effects of Level of Expression. Waveforms in channel 20 at left occipital-temporal sites showed clear differences for different levels of Attractiveness (reflected by P2l) but not for different levels of Expression. (B) Main effect of Level of Expression after excluding the effects of Level of Attractiveness. Waveforms in channel 72 at medial parietal sites showed clear differences among different levels of Expression (reflected by P2m) but not for different levels of Attractiveness. A1, attractive; A2, less attractive; UA2, less unattractive; UA1, unattractive; H1, happy; H2, less happy; S2, less sad; S1, sad.

Mentions: Further analysis supported the double dissociation between the Level of Attractiveness and Level of Expression effects within the 100–200 ms time window (Figure 4). The Level of Attractiveness effect was found to peak in the left occipital-temporal sites at 175 ms (Z = 4.928, cluster size = 492 voxels) after excluding the Level of Expression effect. In contrast, after excluding the Level of Attractiveness effect, the Level of Expression effect was found to peak in the medial parietal sites at 190 ms (Z = 7.151, cluster size = 710 voxels) and in the medial fronto-central sites at 165 ms (Z = 4.848, cluster size = 176 voxels).
