AbstractFearful faces convey threat cues whose meaning is contextualized by eye gaze: While averted gaze is congruent with facial fear (both signal avoidance), direct gaze is incongruent with it, as direct gaze signals approach. We have previously shown using fMRI that the amygdala is engaged more strongly by fear with averted gaze, which has been found to be processed more efficiently, during brief exposures. However, the amygdala also responds more to fear with direct gaze during longer exposures. Here we examined previously unexplored brain oscillatory responses to characterize the neurodynamics and connectivity during brief (∼250 ms) and longer (∼883 ms) exposures of fearful faces with direct or averted eye gaze. We replicated the exposure time by gaze direction interaction in fMRI (N=23), and observed greater early phase locking to averted-gaze fear (congruent threat signal) with MEG (N=60) in a network of face processing regions, with both brief and longer exposures. Phase locking to direct-gaze fear (incongruent threat signal) then increased significantly for brief exposures at ∼350 ms, and at ∼700 ms for longer exposures. Our results characterize the stages of congruent and incongruent facial threat signal processing and show that stimulus exposure strongly affects the onset and duration of these stages.

AbstractBackgroundAltered amygdala activation to fear-related stimuli has been proposed to be a potential neural correlate of heightened threat sensitivity in anxiety- and stress-related disorders. However, the role of stimulus awareness and disorder specificity remains widely unclear. Here we investigated amygdala responses to conscious and unconscious fearful faces in patients suffering from panic disorder (PD), generalized anxiety disorder (GAD), or post-traumatic stress disorder (PTSD) and in a large sample of healthy controls (HC).MethodsDuring event-related functional magnetic resonance imaging participants (n = 120; 20 PD, 20 GAD, 20 PTSD, 60 HC) were confronted with briefly presented fearful faces, neutral faces, and non-faces in a backward masking paradigm. The design allowed for the analysis of trial-by-trial face detection performance and amygdala responses to fearful v. neutral faces.ResultsAll participants exhibited increased amygdala activation to fearful v. neutral faces during conscious trials. Specifically during unconscious face processing, the PTSD, compared with all other groups, showed higher right basolateral (BLA) amygdala activity to fearful v. neutral faces.ConclusionsThe present study shows that BLA amygdala hyperactivity during unconscious, but not conscious, processing of fearful faces differentiates PTSD from the investigated disorders. This finding suggests an automatic and specific neural hyper-responsivity to general fear cues in PTSD and supports the idea of categorical differences between PTSD and other anxiety-related disorders.

Purpose The purpose of this paper is to introduce and examine the effect of a celebrity’s eye gaze on self-celebrity connection. A celebrity’s direct (vs averted) eye gaze can be used as a tactic in social media posts to increase self-celebrity connection and behavioral intentions. Examining the effectiveness of a celebrity’s eye gaze is important, as celebrities regularly use social media to manage their brand image and to build a relationship with consumers. Design/methodology/approach Study 1 examines the effect of a celebrity’s eye gaze (direct vs averted) on self-celebrity connection. Study 2 investigates the role of celebrity authenticity in explaining the effect of a celebrity’s eye gaze on consumer–celebrity brand relationships. Study 3 examines the moderating role of a non-Duchenne smile (fake, social smile) in diluting the effect of a celebrity’s direct eye gaze on self-celebrity connection and the downstream consequences on behavioral intentions. Findings The findings from Study 1 indicate that a celebrity’s direct (averted) eye gaze strengthens (weakens) self-celebrity connection. Study 2 provides evidence of celebrity authenticity as the explanation for stronger consumer–celebrity connection when a celebrity is featured with a direct eye gaze. The results of Study 3 show that a fake smile in a celebrity’s social media posts can weaken relationships with and behavioral intentions toward celebrities with a direct eye gaze. Research limitations/implications This paper is limited, as it focuses only on eye gaze and smiles as non-verbal cues depicted in celebrity images on social media. Practical implications This paper has important implications for celebrities, celebrity brand managers (including digital/social media marketing managers and public relations professionals) and advertisers. Celebrities, celebrity brand managers and advertisers should develop social media posts that can strengthen consumer–celebrity relationships and positively influence behaviors toward the celebrity through: 1) ensuring that photographs are taken with the celebrity looking directly into the camera at the target (audience); and 2) avoiding posting images of a celebrity’s direct eye gaze with a non-Duchenne (fake) smile. Originality/value This paper introduces and provides evidence of a celebrity’s direct eye gaze–self-celebrity relationship effect. Tactics, such as eye gaze, can strengthen consumer–celebrity relationships, which is crucial in building brand equity and in increasing financial value for the celebrity.

Abstract Previous research has shown a link between eye contact and interpersonal motor resonance, indicating that the mirroring of observed movements is enhanced when accompanied with mutual eye contact between actor and observer. Here, we further explored the role of eye contact within a naturalistic two-person action context. Twenty-two participants observed simple hand movements combined with direct or averted gaze presented via a live model in a two-person setting or via video recordings, while transcranial magnetic stimulation was applied over the primary motor cortex (M1) to measure changes in M1 excitability. Skin conductance responses and gaze behavior were also measured to investigate the role of arousal and visual attention herein. Eye contact significantly enhanced excitability of the observer’s M1 during movement observation within a two-person setting. Notably, participants with higher social responsiveness (Social Communication subscale of the Social Responsiveness Scale) displayed a more pronounced modulation of M1 excitability by eye gaze. Gaze-related modulations in M1 excitability were, however, not associated with differences in visual attention or autonomic arousal. In summary, the current study highlights the effectiveness and feasibility of adopting paradigms with high ecological validity for studying the modulation of mirror system processes by subtle social cues, such as eye gaze.

Abstract Human decisions are often influenced by emotions. An economically relevant example is the role of fear in generating loss aversion. Previous research implicates the amygdala as a key brain structure in the experience of fear and loss aversion. The neural mechanism behind emotional influences on loss aversion is, however, unclear. To address this, we measured brain activation with functional magnetic resonance imaging (fMRI) while participants made decisions about monetary gambles after viewing fearful or neutral faces. We observed that loss aversion following the presentation of neutral faces was mainly predicted by greater deactivations for prospective losses (relative to activations for prospective gains) in several brain regions, including the amygdala. By contrast, increases in loss aversion following the presentation of fearful faces were mainly predicted by greater activations for prospective losses. These findings suggest a fear-induced shift from positive to negative value coding that reflects a context-dependent involvement of distinct valuation processes.

Averted Gaze

AbstractThe averted gaze of others triggers reflexive attentional orienting in the corresponding direction. This phenomenon can be modulated by many social factors. Here, we used an eye-tracking technique to investigate the role of ethnic membership in a cross-cultural oculomotor interference study. Chinese and Italian participants were required to perform a saccade whose direction might be either congruent or incongruent with the averted-gaze of task-irrelevant faces belonging to Asian and White individuals. The results showed that, for Chinese participants, White faces elicited a larger oculomotor interference than Asian faces. By contrast, Italian participants exhibited a similar oculomotor interference effect for both Asian and White faces. Hence, Chinese participants found it more difficult to suppress eye-gaze processing of White rather than Asian faces. The findings provide converging evidence that social attention can be modulated by social factors characterizing both the face stimulus and the participants. The data are discussed with reference to possible cross-cultural differences in perceived social status.
