Face processing and its role in the social phenotype of autism spectrum disorders has gained a significant amount of attention in the past decade. The components involved in the processing and use of information from the face represent a network of systems that are complex. This article shows that face processing is neither a simple process nor one that is universally abnormal in individuals with autism. Several complementary processes that may contribute to impairment in (...) face processing in individuals with autism are described. It includes lower-level visual processing, visual attention, early-stage processing of faces, memory for faces, and the emotional significance of faces. The variability in performance on face processing tasks by individuals with ASD reflects an underlying variability in ability in face processing in the ASD spectrum, making face processing a model system for understanding the nature of social impairment in ASD.

Facial emotional recognition is something used often in our daily lives. How does the brain process the face search? Can taste modify such a process? This study employed two tastes to investigate the cross-modal interaction between taste and emotional face recognition. The behavior responses and the event-related potential were applied to analyze the interaction between taste and face processing. Behavior data showed that when detecting a negative target face with a positive face as a (...) distractor, the participants perform the task faster with an acidic taste than with sweet. No interaction effect was observed with correct response ratio analysis. The early and mid-stage [early posterior negativity ] components have shown that sweet and acidic tastes modified the ERP components with the affective face search process in the ERP results. No interaction effect was observed in the late-stage component. Our data have extended the understanding of the cross-modal mechanism and provided electrophysiological evidence that affective facial processing could be influenced by sweet and acidic tastes.

Human faces are one of the most prominent stimuli in the visual environment of young infants and convey critical information for the development of social cognition. During the COVID-19 pandemic, mask wearing has become a common practice outside the home environment. With masks covering nose and mouth regions, the facial cues available to the infant are impoverished. The impact of these changes on development is unknown but is critical to debates around mask mandates in early childhood settings. As infants grow, (...) they increasingly interact with a broader range of familiar and unfamiliar people outside the home; in these settings, mask wearing could possibly influence social development. In order to generate hypotheses about the effects of mask wearing on infant social development, in the present work, we systematically review N = 129 studies selected based on the most recent PRISMA guidelines providing a state-of-the-art framework of behavioral studies investigating face processing in early infancy. We focused on identifying sensitive periods during which being exposed to specific facial features or to the entire face configuration has been found to be important for the development of perceptive and socio-communicative skills. For perceptive skills, infants gradually learn to analyze the eyes or the gaze direction within the context of the entire face configuration. This contributes to identity recognition as well as emotional expression discrimination. For socio-communicative skills, direct gaze and emotional facial expressions are crucial for attention engagement while eye-gaze cuing is important for joint attention. Moreover, attention to the mouth is particularly relevant for speech learning. We discuss possible implications of the exposure to masked faces for developmental needs and functions. Providing groundwork for further research, we encourage the investigation of the consequences of mask wearing for infants’ perceptive and socio-communicative development, suggesting new directions within the research field.

This article delineates two dimensions along which computational models of face processing may vary, and briefly review three such models, the Dailey and Cottrell model; the O'Reilly and Munakata model; and the Riesenhuber and Poggio. It focuses primarily on one of the models and shows how this model is used to reveal potential mechanisms underlying the neural processing of faces and objects—the development of a specialized face processor, how it could be recruited for other domains, hemispheric (...) lateralization of face processing, facial expression processing, and the development of face discrimination. It turns to the Riesenhuber and Poggio model to describe the elegant way it has been used to predict functional magnetic resonance imaging data on face processing. The overall strategy of these modeling efforts is to sample problems that are constrained by neurophysiological and behavioral data, and to stress the ways in which models can generate novel hypotheses about the way humans process faces.

INTRODUCTION TO ASPECTS OF FACE PROCESSING: TEN QUESTIONS IN NEED OF ANSWERS. HD Ellis 1. INTRODUCTION These proceedings of the first international ...

The explosion of research interest in faces and face processing and the engagement of a wide range of disciplines is fueled by theoretical fascination combined with applied importance. This article describes some of the psychological research that has accompanied the recent rapid development or deployment of systems for showing, building, or manipulating faces for a variety of purposes. It illustrates the psychological issues that arise in a range of engineering, medical, and legal contexts and shows that technological development (...) has not always been matched by an appreciation of the psychological issues that need to be overcome to take full advantage of new systems. In some areas the advances raise new psychological issues. New technology has simply replicated old problems—e.g. that witnesses cannot recall individual face features; or that resemblance and identity are not the same thing. (shrink)

The recognition memory for inverted faces is especially difficult when compared with that for non-face stimuli. This face inversion effect has often been used as a marker of face-specific holistic processing. However, whether face processing without awareness is still specific remains unknown. The present study addressed this issue by examining the face inversion effect with the technique of binocular rivalry. Results showed that invisible upright faces could break suppression faster than invisible inverted faces. (...) Nevertheless, no difference was found for invisible upright houses and invisible inverted houses. This suggested that face processing without awareness is still specific. Some face-specific information can be processed by high-level brain areas even when that information is invisible. (shrink)

This article focuses on the corresponding research findings pertaining to developmental changes throughout infancy to adolescence in processing various bits of face trait information. It examines whether faces are indeed a special class of stimuli. The role of experience in developing species-specific face expertise and standards of attractiveness are discussed. The research on infants' and children's categorization of different face types aids in exploring how the development of face categorization is influenced by experience. The article (...) reviews evidence concerning the development of face identity discrimination and recognition and more specifically the controversy regarding whether such development undergoes a qualitative change during childhood. It deals with infants and children's use of three types of facial information: featural information, configural information, and holistic information. (shrink)

Previous work suggests that Asians allocate more attention to configuration information than Caucasian Americans do. Yet this cultural variation has been found only with stimuli such as natural scenes and objects that require both feature- and configuration-based processing. Here, we show that the cultural variation also exists in face perception—a domain that is typically viewed as configural in nature. When asked to identify a prototypic face for a set of disparate exemplars, Japanese were more likely than Caucasian (...) Americans to use overall resemblance rather than feature matching. Moreover, in a speeded identity-matching task, Japanese were more accurate than Americans in identifying the spatial configuration of features (e.g., eyes). Together, these findings underscore the robustness of culture’s influences on cognition. (shrink)

This article explores the concept of recognizing a face holistically and examines the experimental paradigms that serve as the “gold standards” for holistic perception. It discusses the contribution of featural and configural information to the holistic process and the controversy surrounding these often misunderstood concepts. It claims that the recruitment of holistic processes is what distinguishes faces from most types of object recognition. The discussion focuses on the kind of featural and configural information that is impaired in an inverted (...) face as well as the information that is spared. Finally, the article considers the concept of a “perceptual field” that allows for the preservation of both featural and configural information within a restricted spatial region of an inverted face.

A common view in face recognition research holds that there is a stored representation specific to each known face. It is also posited that semantic or memory-based information cannot influence low-level face processing. The two experiments reported in this article investigate the nature of this representation and the flow of face information processing. Participants had to search for a particular primed face among other faces. In Experiment 1, the search was done in a (...) context where distractors had either a different degree of fame or the same degree of fame. In Experiment 2, the target face was primed either with semantic information or without any information. Both experiments demonstrated that increasing the display set size lengthened face detection time. However, the lengthening was a function of face fame. The search context also had an effect on the slope of the famous face detection. The results are explained in terms of the idea that face representations are reconstructed and that high- and low-level information are integrated into the processing. The integration process is not a conscious one. (shrink)

Phylogenetic, epigenetic, and neurophysiological data characterize the specificity and limitations of the systems that support individual face recognition in human and non-human primates. The central question of the recognition of the faces of other species explores the processes that lead to the remarkable face expertise that humans and non-humans develop for members of their own species. This article reviews the literature on categorization/recognition abilities within and across species in human and non-human primates. It evaluates whether it is possible (...) for a species to perceive other species faces at the same level of expertise as for their own species. The neural substrate and the current models of neuronal processing that support face processing in human and non-human primates are described. Finally, it discusses the developmental data pertaining to face processing in human and non-human primates, challenging the view that face processing can be plastic in adults. (shrink)

Neuropsychological patients exhibiting category-selective visual agnosias provide unique insights into the cognitive functions of the human brain. Transcranial magnetic stimulation, in contrast, can be used to draw causal inferences, as one of the effects of the cortical disruption induced by magnetic stimulation is to act as a “virtual lesion” lasting from tens of milliseconds up to approximately one hour, depending on the type of stimulation. This specificity offers a unique advantage in psychological testing as TMS can be used to test (...) where and when cognitive computations are performed. This article briefly describes TMS, considers the small but growing number of studies that use TMS to disrupt face processing. It discusses how TMS can be used in the future to understand better how faces are cortically represented in the human brain. (shrink)

Visual processing is thought to function in a coarse-to-fine manner. Low spatial frequencies, conveying coarse information, would be processed early to generate predictions. These LSF-based predictions would facilitate the further integration of high spatial frequencies, conveying fine details. The predictive role of LSF might be crucial in automatic face processing, where high performance could be explained by an accurate selection of clues in early processing. In the present study, we used a visual Mismatch Negativity paradigm by (...) presenting an unfiltered face as standard stimulus, and the same face filtered in LSF or HSF as deviant, to investigate the predictive role of LSF vs. HSF during automatic face processing. If LSF are critical for predictions, we hypothesize that LSF deviants would elicit less prediction error than HSF deviants. Results show that both LSF and HSF deviants elicited a mismatch response compared with their equivalent in an equiprobable sequence. However, in line with our hypothesis, LSF deviants evoke significantly reduced mismatch responses compared to HSF deviants, particularly at later stages. The difference in mismatch between HSF and LSF conditions involves posterior areas and right fusiform gyrus. Overall, our findings suggest a predictive role of LSF during automatic face processing and a critical involvement of HSF in the fusiform during the conscious detection of changes in faces. (shrink)

Individuals with autism spectrum disorder (ASD) demonstrate poor social functioning, which may be related to atypical emotional face processing. Altered functional connectivity among brain regions, particularly involving limbic structures may be implicated. The current magnetoencephalography (MEG) study investigated whole-brain functional connectivity of eight a priori identified brain regions during the implicit presentation of happy and angry faces in 20 7 to 10-year-old children with ASD and 22 typically developing controls. Findings revealed a network of increased alpha-band phase synchronization (...) during the first 400 ms of happy face processing in children with ASD compared to controls. This network of increased alpha-band phase synchronization involved the left fusiform gyrus, right insula, and frontal regions critical for emotional face processing. In addition, greater connectivity strength of the left fusiform gyrus (maximal 85 to 208 ms) and right insula (maximal 73 to 270 ms) following happy face presentation in children with ASD compared to typically developing controls was found. These findings reflect altered neuronal communication in children with ASD only to happy faces during implicit emotional face processing. (shrink)

Arguably the most influential models of human decision-making today are based on the assumption that two separable systems – intuition and deliberation – underlie the judgments that people make. Our recent work is among the first to present neural evidence contrary to the predictions of these dual-systems accounts. We measured brain activations using functional magnetic resonance imaging (fMRI) while participants were specifically instructed to either intuitively or deliberately judge the authenticity of emotional facial expressions. Results from three different analyses revealed (...) both common brain networks of activation across decision mode and differential activations as a function of strategy adherence. We take our results to contradict popular dual-systems accounts that propose a clear-cut dichotomy of the processing systems, and to support rather a unified model. According to this, intuitive and deliberate judgment processes rely on the same rules, though only the former are thought to be characterized by non-conscious processing. (shrink)

Face recognition confronts the same fundamental challenge as all object recognition: the identification of individuals belonging to a specific category despite a huge range in possible appearances. The specialized architecture of the face patch system—the concentration of face cells into modules and the spatial separation of modules—makes it possible to dissect the steps leading to invariant object recognition in unprecedented detail. It discusses both anatomical experiments revealing the connectivity of the six face patches and electrophysiological experiments (...) revealing the response selectivity of single units within the patches. It reviews insights into this question obtained from fMRI and electrophysiological experiments in macaque monkeys. It presents evidence that macaques have specialized face regions and discusses their anatomical connectivity as well as functional properties measured with both fMRI and targeted electrophysiology.
