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.

Main effect of level of attractiveness. Waveforms are shown in the representative channels 20 (left occipital-temporal), 99 (right occipital-temporal), and 120 (right temporal). The waveforms of P2l are only shown from −100 to 300 ms to clarify the details of each level of Level of Attractiveness. The 2D topographies are shown for the amplitudes averaged within the intervals 150–200, 220–260, and 825–900 ms, respectively. To clarify the difference between different levels of Attractiveness, mean amplitudes averaged across all conditions were removed from the 2D topographies. The shadowed bars represent the time windows' detecting significance, the small circles locate the representative channels, and the color bar denotes the range of amplitudes (μV). A1, attractive; A2, less attractive; UA2, less unattractive; UA1, unattractive.

A1, attractive; A2, less attractive; UA2, less unattractive; UA1, unattractive.

Mentions: The waveforms and 2D topographies for the Level of Attractiveness effect are presented in Figure 2. The Level of Attractiveness effect was found to be significant in three voxel clusters within the 80–980 ms time window. The first cluster was in the left occipito-temporal region within the 220–260 ms period. The UA1 faces elicited more negative-going amplitudes than did the A2 faces. The second cluster was in the medial centro-parietal region within the 510–610 ms period. The results of this cluster will be elaborated later under the results of the interaction between Level of Attractiveness and Level of Expression. The third cluster was at the right temporal region within the 825–900 ms period. Post-hoc analyses showed that UA1 faces elicited more negative-going amplitudes than any other faces.
