Faces are among the most important visual stimuli that we perceive in everyday life. Although there is a plethora of literature studying many aspects of face perception, the vast majority of them focuses on a single aspect of face perception using unimodal approaches. In this review, we advocate for studying face perception using multimodal cognitive neuroscience approaches. We highlight two case studies: the first study investigates ambiguity in facial expressions of emotion, and the second study investigates social trait judgment. In the first set of studies, we revealed an event-related potential that signals emotion ambiguity and we found convergent response to emotion ambiguity using functional neuroimaging and single-neuron recordings. In the second set of studies, we discussed recent findings about neural substrates underlying comprehensive social evaluation, and the relationship between personality factors and social trait judgements. Notably, in both sets of studies, we provided an in-depth discussion of altered face perception in people with autism spectrum disorder (ASD) and offered a computational account for the behavioral and neural markers of atypical facial processing in ASD. Finally, we suggest new perspectives for studying face perception. All data discussed in the case studies of this review are publicly available.

IntroductionIndividuals with Autism Spectrum Disorder (ASD) show atypical recognition of facial emotions, which has been suggested to stem from arousal and attention allocation. Recent studies have focused on the ability to perceive an average expression from multiple spatially different expressions. This study investigated the effect of autistic traits on temporal ensemble, that is, the perception of the average expression from multiple changing expressions.MethodsWe conducted a simplified temporal-ensemble task and analyzed behavioral responses, pupil size, and viewing times for eyes of a face. Participants with and without diagnosis of ASD viewed serial presentations of facial expressions that randomly switched between emotional and neutral. The temporal ratio of the emotional expressions was manipulated. The participants estimated the intensity of the facial emotions for the overall presentation.ResultsWe obtained three major results: (a) many participants with ASD were less susceptible to the ratio of anger expression for temporal ensembles, (b) they produced significantly greater pupil size for angry expressions (within-participants comparison) and smaller pupil size for sad expressions (between-groups comparison), and (c) pupil size and viewing time to eyes were not correlated with the temporal ensemble.DiscussionThese results suggest atypical temporal integration of anger expression and arousal characteristics in individuals with ASD; however, the atypical integration is not fully explained by arousal or attentional allocation.

“…It has been shown that people with ASD demonstrate reduced specificity to emotions (Figure3A,C), although their eye movement patterns are remarkably similar compared to neurotypicals and they have normal thresholds to report fear (Figure3A,B). In addition, in this task, people with ASD demonstrate reduced pupil oscillation when judging faces with ambiguous facial expressions (Figure3D,E) 108.…”

Faces are among the most important visual stimuli that humans perceive in everyday life. While extensive literature has examined emotional processing and social evaluations of faces, most studies have examined either topic using unimodal approaches. In this review, we promote the use of multimodal cognitive neuroscience approaches to study these processes, using two lines of research as examples: ambiguity in facial expressions of emotion and social trait judgment of faces. In the first set of studies, we identified an event‐related potential that signals emotion ambiguity using electroencephalography and we found convergent neural responses to emotion ambiguity using functional neuroimaging and single‐neuron recordings. In the second set of studies, we discuss how different neuroimaging and personality‐dimensional approaches together provide new insights into social trait judgments of faces. In both sets of studies, we provide an in‐depth comparison between neurotypicals and people with autism spectrum disorder. We offer a computational account for the behavioral and neural markers of the different facial processing between the two groups. Finally, we suggest new practices for studying the emotional processing and social evaluations of faces. All data discussed in the case studies of this review are publicly available.
