In recent years, many studies have shown that perceiving other individuals’ direct gaze has robust effects on various attentional and cognitive processes. However, considerably less attention has been devoted to investigating the affective effects triggered by eye contact. This article reviews research concerning the effects of others’ gaze direction on observers’ affective responses. The review focuses on studies in which affective reactions have been investigated in well-controlled laboratory experiments, and in which contextual factors possibly influencing perceivers’ affects have been (...) controlled. Two important themes emerged from this review. First, explicit affective evaluations of seeing another’s direct versus averted gaze have resulted in rather inconsistent findings; some studies report more positive subjective feelings to direct compared to averted gaze, whereas others report the opposite pattern. These contradictory findings may be related, for example, to differences between studies in terms of the capability of direct-gaze stimuli to elicit feelings of self-involvement. Second, studies relying on various implicit measures have reported more consistent results; they indicate that direct gaze increases affective arousal, and more importantly, that eye contact automatically evokes a positively valenced affective reaction. Based on the review, possible psychological mechanisms for the positive affective reactions elicited by eye contact are described. (shrink)

(This version was submitted to Behavioral and Brain Science. A revised version was published by Biological Theory) Estimates of autism’s incidence increased 5-10 fold in ten years, an increase which cannot be genetic. Though many mutations are associated with autism, no mutation seems directly to cause autism. We need to find the direct cause. Complexity science provides a new paradigm - confirmed in biology by extensive hard data. Both the body and the personality are complex dynamic systems which spontaneously self-organize (...) from simple dynamic systems. Autism may therefore be caused by the failure of a simple dynamic system. We know that infants who cannot track their mother’s face often become autistic, that eye-contact initiates intersubjectivity which is blocked in autism, and that the infant-mother pair seems designed to promote eye-contact, as does the eye’s appearance. This author earlier proposed that failure of eye-contact might directly cause autism and that early non-maternal childcare, including television/video, would therefore be statistically linked to autism. Waldman et al. (2008; 2006) recently proved that autism is strongly linked to precipitation (indoor activity) and to the introduction of cable. The most plausible explanation? Early exposure to television/video is linked to autism. Furthermore a normal developmental cascade (blocked in autism) has been deciphered: (a) Infant-mother eye-contact triggers increased maternal attention. (b) Early maternal attention permanently increases not only baseline vasopressin but also that oxytocin release which is triggered by subsequent maternal attention. (c) Vasopressin and oxytocin promote face recognition, gazing-at-the-eyes, emotion recognition, and social bonding. The eye-contact hypothesis suggests a clinical study addressing prevention: recruit prospective parents who agree to curtail television/video/computer/wi-fi in their families; measure autism’s incidence in their children.

Eye contact plays a critical role in many aspects of face processing, including the processing of smiles. We propose that this is achieved by a subcortical route, which is activated by eye contact and modulates the cortical areas involve in social cognition, including the processing of facial expression. This mechanism could be impaired in individuals with autism spectrum disorders.

Eye-contact facilitates effective interpersonal exchange during social interactions, but can be a considerable source of anxiety for individuals with social phobia. However, the relationship between the fundamental spatial range of eye-contact perception and psychiatric traits is, to date, unknown. In this study, I analyzed the eye-contact spatial response bias and the associated pupil response, and how they relate to traits of social interaction disorders. In a face-to-face situation, 21 pairs of subjects were randomly assigned to be either (...) viewers or perceivers. The viewer was instructed to gaze either at the perceiver’s eyes, or at a predetermined point, and the perceiver was asked to indicate whether eye-contact had been established or not. I found that the perceptual volume is much larger than the actual volume of eye-contact, and that the subjective judgment of eye-contact elicited greater pupil dilation in the perceiver. Furthermore, the relationship between behavioral performance and social anxiety traits was identified. These findings provide new indications that internal traits related to lower social anxiety are potentially related to a restriction of spatial response bias for eye-contact. (shrink)

Eye contact is an essential element of human interaction and direct eye gaze has been shown to have effects on a range of attentional and cognitive processes. Specifically, direct eye contact evokes a positive affective reaction. As such, it has been proposed that obstructed eye contact reduces emotional mimicry. So far, emotional mimicry research has used averted-gaze faces or unnaturally covered eyes to analyze the effect of eye contact on emotional mimicry. However, averted gaze can also (...) signal disinterest/ disengagement and censor bars obscure eye-adjacent areas as well and hence impede emotion recognition. In the present study, we used a more ecological valid approach by showing photos of actors who expressed either happiness, sadness, anger, or disgust while either wearing mirroring sunglasses that obstruct eye contact or clear glasses. The glasses covered only the direct eye region but not the brows, nose ridge, and cheeks. Our results confirm that participants were equally accurate in recognizing the emotions of their counterparts in both conditions. Further, in line with our hypotheses, participants felt closer to the targets and mimicked affiliative emotions more intensely when their counterparts wore glasses instead of sunglasses. For antagonistic emotions, we found the opposite pattern: Disgust mimicry, which was interpreted as an affective reaction rather than genuine mimicry, could be only found in the sunglasses condition. It may be that obstructed eye contact increased the negative impression of disgusted facial expressions and hence the negative feelings disgust faces evoked. The present study provides further evidence for the notion that eye contact is an important prerequisite for emotional mimicry and hence for smooth and satisfying social interactions. (shrink)

In a longitudinal naturalistic study, we observed German mothers interacting with their infants when they were 3 and 6 months old. Pursuing the idea that infants’ attention is socialized in everyday interactions, we explored whether eye contact is reinforced selectively by behavioral modification in the input provided to infants. Applying a microanalytical approach focusing on the sequential organization of interaction, we explored how the mother draws the infant’s attention to herself and how she tries to maintain attention when the (...) infant is looking at her. Results showed that eye contact is reinforced by specific infant-directed practices: interrogatives and conversational openings, multimodal stimulation, repetition, and imitation. In addition, these practices are contingent on the infant’s own behavior. By comparing the two data points (3 and 6 months), we showed how the education of attention evolves hand-in-hand with the developing capacities of the infant. Keywords: multimodal input; eye contact; interactional adaptation; ecology of attention; social learning. (shrink)

This article attempts to show why an experimental hypothesis is plausible and merits testing; in brief, the hypothesis is that autism begins with a failure in early learning and that changing the environment of early learning would dramatically change its incidence. Strong statistical evidence supporting this hypothesis has been published by Waldman et al. (2008), but to date this evidence has largely been ignored, perhaps because it challenges prevalent beliefs about autism. This article also suggests that the current epidemic of (...) autism is serious enough, and intellectually mysterious enough, to merit attention from a wider community of brain scientists: New ideas are needed. A confirmation of this article’s hypothesis would have interesting implications for brain science. (shrink)

Communication between road users is a major key to coordinate movement and increase roadway safety. The aim of this work was to grasp how pedestrians, cyclists, and kick scooter users sought to visually communicate with drivengers when they would face autonomous vehicles. In each experiment, participants were asked to imagine themselves in described situations of encounters between a specific type of vulnerable road user and a human driver in an approaching car. The human driver state and the communicative means of (...) the approaching car through an external Human-Machine Interface were manipulated between the scenarios. The participants were prompted to rate from “never” to “always” the frequency with which they would seek eye contact with the human driver either in order to express their willingness to cross or to make their effective decision to cross. Our findings revealed that a passive human driver in an AV with no visual checking on the road triggered a decline in vulnerable road users’ desire to communicate by eye contact. Moreover, the results of Experiment C demonstrated that the speed screen, the text message screen, and the vibrating mobile app eHMI signals diminished kick scooter users’ desire to communicate visually with the human driver, with some age-based differences. This suggested a better comprehension of the approaching car’s intentions by the kick scooter users, driven by the features of the eHMI. (shrink)

This study looks into the role that eye contact plays in helping people to control themselves in social settings and to avoid breaking social norms. Based on previous research, it is likely that eye contact increases prosocial behavior via heightened self-awareness and increased interpersonal synchrony. In our study, we propose that eye contact can also support constructive social behavior by causing people to experience heightened embarrassment when they are breaking social norms. We tested this in a lab (...) experiment in which participants read insults at the experimenter. In the experimental condition, participants maintained eye contact with the experimenter. In the control condition, the experimenter did not maintain eye contact. We measured embarrassment with a self-report measure, heart rate to capture arousal, and two observational indicators of embarrassment. In line with our hypotheses, having eye contact during norm breaking behavior as compared to no eye contact led to a stronger increase in self-reported embarrassment, a higher heart rate as well as more hesitation and more laughter. We conclude that eye contact does indeed lead to more embarrassment, while breaking social norms. This implies that eye contact gives people the power to punish norm breaking in others by inducing an aversive emotional experience. (shrink)

How should we understand the special way in which two people are connected when they make eye contact? In this paper, I argue that existing accounts of eye contact —Peacocke’s Reductive Approach and Eilan’s Second Person Approach— are unsatisfactory. In doing so, I make a case for thinking that the source of this dissatisfaction and the path forward can be identified by reflecting on our tendency to describe eye contact on the model of touch. On this basis, (...) I outline a ‘Transactional Approach’ to eye contact. (shrink)

Previous research has shown that angry and happy faces are perceived as less emotionally intense when shown with averted versus direct gaze. Other work reports that long-term memory for angry faces was poorer when they were encoded with averted versus direct gaze, suggesting that threat signals are diluted when eye contact is not engaged. The current study examined whether gaze modulates working memory for angry and happy faces. In stark contrast to LTM effects, WM for angry faces was not (...) significantly modulated by gaze direction. However, WM for happy faces was significantly enhanced when gaze was averted versus direct. These findings suggest that in WM – when rapid processing and an immediate response is required – averted gaze may alter the meaning behind a smile, and make this kind of expression particularly salient for short-term processing.

This commentary raises general questions about the parsimony and generalizability of the SIMS model, before interrogating the specific roles that the amygdala and eye contact play in it. Additionally, this situates the SIMS model alongside another model of facial expression processing, with a view to incorporating individual differences in emotion perception.

This paper seeks to demonstrate the structural difference in communication of schizophrenia and autism. For a normal adult, spontaneous communication is nothing but the transmission of phantasía (thought) by means of perceptual objects or language. This transmission is first observed in a make-believe play of child. Husserl named this function “perceptual phantasía,” and this function presupposes as its basis the “internalized affection of contact” (which functions empirically in eye contact, body contact, or voice calling me). Regarding autism, (...) because of the innate lack of affection of contact, intersubjective perceptual phantasía does not occur spontaneously. Consequently, autistics do not engage in make-believe play but in stereotyped and solipsistic play. Without the formation of perceptual phantasía, there is no differentiation between phantasía and perception. For this reason, people with Asperger's syndrome consider conversation not an immediate communication of thought but a logical transmission of concepts. Schizophrenia is characterized by a distortion in the internalized affection of contact, resulting in a disturbance of perceptual phantasía, and this later is covered by various symptoms—for example, delusion as a pathological kind of communication of thought. This delusion is based on the pathological internalized affection of contact represented by a terrifying Other. (shrink)

Surface has become an important consideration of sensory film theory, conceived of in various forms: the screen itself as less a barrier than a permeable skin, the site of a meaningful interaction between film and audience; the image as a surface to be experienced haptically, the eye functioning as a hand that brushes across and engages with the field of vision; surfaces within the film, be they organic or fabricated, presenting a tactile appeal. Surface evokes contact and touch, the (...) look or sound it produces inviting consideration of its materiality, and perhaps even a tactile interchange. If the surface of film, across its varied associations, presents the possibility of an intersubjective contact between film and audience, this article seeks to include another body: that of the filmmaker. There are many people who contribute to the material constitution of a film and I would suggest that we might seek to appreciate its textures just as we might that of a painting. Focus on the fine...

Cambridge: MIT P, 1992.“To the insides of the ear belong those who have a sight of internal hearing.” That’s the nocturnal look, the listening eye.—Emmanuel Swedenborg, cited in Lyotard, The InhumanPostmodernism, Yet AgainIn this essay, I shall take a cue from Slavoj Zizek’s discussion of Lacanian anamorphosis, or skewed perspective (Looking Awry), in order to read three dissimilar works alongside one another, and from a “paranoid” slant. For in spite of sometimes radically incommensurate subject matter, the three works I discuss here—The Transparency of Evil (Jean Baudrillard), Looking Awry (Slavoj Zizek) and The Inhuman (Jean-François Lyotard)—all share a focus on the dehumanizing effects of technology as determinants of what Lyotard has called the postmodern condition. 1 Moreover, all three works themselves adopt something like a paranoid perspective, suggesting that under the sway of an ethic of sheer performativity, human contact—face to face—has been rendered obsolete by interface.In the bleak vision of The Transparency of Evil (1993), for instance, Baudrillard describes an isolated disembodied satellite man, cut loose from his moorings: “The centrifugal force of our proliferating technologies has stripped us of all weight.... Freed of all density, all gravity, we are being dragged into an orbital motion which threatens to become perpetual” [30–31]. Similarly, in “The Ecstasy of Communication” (1983), Baudrillard describes a robotic subject mesmerized by pornographic hypervisibility, [End Page 90] “more visible than the visible... the obscenity of what no longer has any secret, or what dissolves completely in information and communication” [130–31]. 2Like Baudrillard, Lyotard (The Inhuman) describes the loss of dimensional intersubjectivity, suggesting that space is no longer an enabling interval between subjects, the scene of the exchanged gaze: contemporary cyberspace is the scene of communication without community, saturated with hypervisible information. But while for Baudrillard, we are already in weightless orbit, in a postcatastrophic, fractal aftermath, for Lyotard our fate is not yet cast, although adumbrated disaster—the end of the species or of the universe—provides a telos for our existence.Slavoj Zizek is not nearly so metaphysical, nor so glum, as his fellow post-philosophers, but he is every bit as concerned with the optical, Looking Awry. Zizek is a patient and even cheery exegete of Lacan, attempting to “introduce” Lacanian thought by looking at film, detective fiction, and other user-friendly instances of modern culture as templates of theory. Indeed, compared to his fellow travelers, Zizek is resolutely quotidian, even earthbound, focusing on the contemporary human subject as consumer/spectator, seated not in a satellite capsule or at a computer terminal but at the movies, popcorn in hand.Yet in spite of his goodwill, Zizek’s take on postmodernism is anything but sanguine: he too depicts a subject who is prey to the fascination of overexposed “obscene” virtual reality (X-rated Hitchcock, if you will), and always threatened as well by the eruption of the menacing Lacanian real into the web of symbolic reality—an intrusion that awakens the paranoid “post-man” from an absorption in the image on the screen, with a reminder of the precariousness of all that appears evident or meaningful. Thus in “The Obscene Object of Postmodernity” [Looking Awry, chap. 8], Zizek describes a blot or stain that sticks out or refuses assimilation to the totalizing gaze, eclipsing the heretofore meaningful and legible symbolic universe with an ineffable real that “produces a radical opacity and blocks every essay of interpretation” [151]. I suggest that Zizek’s notion of the obscene object as blot—like the hair on the camera lens that “disturbs” our absorption in the screen—as well as Lyotard’s notion of obdurate matter, may...

—Human eyes not only serve the function of enabling us “to see” something, but also perform the vital role of allowing us “to show” our gaze for non-verbal communication, such as through establishing eye contact and joint attention. The eyes of service robots should therefore also perform both of these functions. Moreover, they should be friendly in appearance so that humans may feel comfortable with the robots. Therefore we maintain that it is important to consider gaze communication capability and (...) friendliness in designing the appearance of robot eyes. In this paper, we propose a new robot face with rear-projected eyes for changing their appearance while simultaneously realizing the showing of gaze by incorporating stereo cameras. Additionally, we examine which shape of robot eyes is most suitable for gaze reading and gives the friendliest impression, through experiments where we altered the shape and iris size of robot eyes.
