Not to follow because of distrust: perceived trust modulates the gaze cueing effect.

In social life, people spontaneously form stable trustworthiness impressions from faces. However, the precise role of extracting trustworthiness information remains unclear. This study aims to elucidate whether discerning facial trustworthiness influences social interactions. Specifically, it explores the gaze cueing effect (GCE), wherein individuals exhibit quicker responses to targets appearing in the direction of gaze compared to other locations. Given conflicting perspectives in existing literature regarding the potential modulation of trustworthiness on the GCE, two plausible hypotheses are proposed to explain divergent result patterns. The reflexive hypothesis posits that the GCE operates automatically. In contrast, the flexible hypothesis underscores the potential modulatory role of trustworthiness in the GCE. To provide a comprehensive understanding of whether trustworthiness modulates the GCE, we employed face stimuli incorporating trustworthiness information within Posner' s cue-target task. The findings of Experiment 1 revealed that the perception of trustworthiness indeed influenced the GCE. Specifically, when facial stimuli were perceived as trustworthy, they elicited a more pronounced GCE compared to untrustworthy stimuli. This modulation effect was replicated using a different stimulus set in Experiment 2. In Experiment 3, we employed the same stimuli as in Experiment 2, setting the trustworthiness information to baseline as a control experiment. The results demonstrated that the trustworthiness modulation effect disappeared, indicating its specificity to the trustworthiness attribute of the stimuli rather than other characteristics. Collectively, these findings lend support to the flexible hypothesis, highlighting that the extraction of trustworthiness information plays a pivotal role in modulating the GCE, consequently influencing social interactions.

The emotion of sound target modulates the auditory gaze cueing effect

ABSTRACT The auditory gaze cueing effect (auditory-GCE) is a faster response to auditory targets at an eye-gaze cue location than at a non-cue location. Previous research has found that auditory-GCE can be influenced by the integration of both gaze direction and emotion conveyed through facial expressions. However, it is unclear whether the emotional information of auditory targets can be cross-modally integrated with gaze direction to affect auditory-GCE. Here, we set neutral faces with different gaze directions as cues and three emotional sounds (fearful, happy, and neutral) as targets to investigate how the emotion of sound target modulates the auditory-GCE. Moreover, we conducted a controlled experiment using arrow cues. The results show that the emotional content of sound targets influences the auditory-GCE but only for those induced by facial cues. Specifically, fearful sounds elicit a significantly larger auditory-GCE compared to happy and neutral sounds, indicating that the emotional content of auditory targets plays a modulating role in the auditory-GCE. Furthermore, this modulation appears to occur only at a higher level of social meaning, involving the integration of emotional information from a sound with social gaze direction, rather than at a lower level, which involves the integration of direction and auditory emotion.

Threat priming diminishes the gaze cueing effect

ABSTRACT Gaze cueing effect (GCE) refers to attention orienting towards the gazed-at location, characterised by faster responses to gazed-at than non-gazed-at stimuli. A previous study investigated the effects of affective priming on GCE and reported that threatening primes enhanced GCE. However, it remains unknown whether the threat or heightened arousal potentiated GCE. We investigated how highly arousing threatening and positive primes, compared to low arousing neutral primes modulate GCE. After a brief exposure to an affective prime (pictures of threat or erotica) or a neutral prime, participants detected an asterisk validly or invalidly cued by the gaze direction of a neutral face. The results showed that the threatening primes diminished the magnitude of GCE. The highly arousing positive primes did not have an effect on GCE. Further analyses showed that, as compared to neutral priming, the reaction times after threatening primes were shortened on invalid trials. This finding was interpreted to suggest that the threatening primes enhanced goal-directed target detection and attenuated attention orienting by irrelevant gaze cues via improving executive control. In sum, the present findings indicate that threat priming modulates GCE, not because of heightened arousal but because of the threat.

I prefer what you can see: The role of visual perspective-taking on the gaze-liking effect

Individuals' gaze on an object usually leads others to prefer that object, which is called the gaze-liking effect. However, it is still unclear whether this effect is driven by social factors (i.e., visual perspective-taking) or the domain-general processing (i.e., attention cueing). This research explored the mechanism of the gaze-liking effect by manipulating the objects' visibility to an avatar in six online one-shot experiments. The results showed that participants' affective evaluation for the object was modulated by the avatar's visual perspective. Specifically, the visible object to the avatar received a higher rating of liking degree. However, when the avatar was replaced with a non-social stimulus, the experimental effect was absent. Furthermore, the gaze-liking effect was robust while controlling for confounding factors such as the distance between the object and the avatar or type of stimuli. These findings provided convincing evidence that the gaze-liking effect involves a process of the other's visual experience and is not merely a by-product of the gaze-cueing effect.

Social excluder's face reduces gaze-triggered attention orienting.

Social ostracism, a negative affective experience in interpersonal interactions, is thought to modulate the gaze-cueing effect (GCE). However, it is unclear whether the impact of social exclusion on the GCE is related to the identity of the cueing face. Therefore, the present study employed a two-phase paradigm to address this issue. In the first phase, two groups of participants were instructed to complete a Cyberball game with two virtual avatars to establish a binding relationship between a specific face's identity and the emotions of social exclusion or inclusion. In the second phase, these two virtual avatars (exclusion faces/inclusion faces) and two new faces (control faces) were used as cueing faces in the gaze-cueing task. The results found that, for the exclusion group, the magnitudes of the GCEs for the exclusion and exclusion-control faces were similar in the 200 ms stimulus onset asynchrony (SOA) condition, while the exclusion face's GCE was significantly smaller than that of the exclusion-control face in the 700 ms SOA condition. In contrast, for the inclusion group, the GCEs for inclusion and inclusion-control faces in both the 200 ms SOA and 700 ms SOA conditions did not significantly differ. This study reveals that the effect of social exclusion on the GCE is related to the identity of the cueing face, with individuals more reluctant to follow the gaze direction of excluder and shift their attention and provides experimental evidence that the perception of higher social relations can exert a top-down impact on the processing of social spatial cues.

Reduced gaze-cueing effect with neutral and emotional faces in adults with attention deficit/hyperactivity disorder

This study examined whether gaze shift of neutral and emotional faces triggers reflexive attention orienting in 45 adults with attention deficit/hyperactivity disorder (ADHD) and 45 age-, sex-, and intelligence quotient-matched typically developing (TD) adults. The cues changed from neutral to anger, fearful, or happy expressions under the emotional face condition. Participants were asked to detect a target that appeared to the left or right of the cue stimuli, as rapidly and accurately as possible. The results revealed a gaze-cueing effect, where the reaction time to the target was shorter under the “gaze-at-target” condition than under the “non-gaze-at-target” condition in both groups. Facial expressions did not modulate the gaze-cueing effect in either group. However, the magnitude of the gaze-cueing effect was smaller in the ADHD group than in the TD group. Contrary to our expectations, a larger gaze-cueing effect was observed in individuals with ADHD who exhibited more severe inattention. Our results suggest that adults with ADHD ineffectively orient their attention toward another's gaze. Moreover, difficulty with sustained and selective attention may be associated with a larger influence of gaze direction; this difficulty may play a role in social interaction problems.

Testing the effects of gaze distractors with invariant spatial direction on attention cueing.

In four experiments, we tested the boundary conditions of gaze cueing with reference to the resistance to suppression criterion of automaticity. Participants were asked to respond to peripheral targets preceded by a central gaze stimulus. Under one condition, gaze direction was random and uninformative with respect to target location (intermixed condition), as in the typical paradigm. Under another condition, gaze direction was uninformative and, crucially, it was also kept constant throughout the sequence of trials (blocked condition). In so doing, we aimed at maximally reducing the informative value of the gaze stimulus because gaze would not only be task-irrelevant but would also provide no sudden and unpredictable information. Across the four experiments, the results showed a strong gaze-cueing effect. More specifically, a comparable gaze cueing emerged under the blocked and intermixed conditions. These findings are consistent with the idea that gaze cueing is resistant to suppression and are discussed in relation to current views of the automaticity of gaze cueing.

The attractiveness of face cues does not modulate the gaze cuing effect

ABSTRACT The gaze cuing effect refers to the finding that participants are faster to respond to a stimulus preceded by a face gazing towards the stimulus location compared to when a stimulus is preceded by a face gazing away from the stimulus location. This effect is found even when the gaze direction is not informative of the upcoming stimulus location, suggesting the operation of a fast, reflexive process that draws attention. However, accumulating evidence suggests that this gaze cuing effect is modulated by additional contextual features including characteristics of the face stimulus. In the current set of experiments, we sought to test whether the attractiveness of the face cue is one such factor. Across three experiments, we found no evidence that attractiveness impacts the gaze cuing effect. We interpret these findings to mean that perceived attractiveness is not a contextual feature that modulates the impact of gaze on spatial attention.

Emotional modulation of gaze cueing does not depend on a global perceptual processing strategy.

Research on emotional modulation of attention in gaze cueing has resulted in contradictory findings. Some studies found larger gaze cueing effects (GCEs) in response to a fearful gaze cue, whereas others did not. A recent study explained this discrepancy within a cognitive resource account, in which perceptual demands of the task promote a bias toward either a local (discrimination task) or global (localization task) processing strategy. During local processing, the integration of emotional expression with gaze direction is assumed to be impaired, whereas during global processing integration is assumed to be facilitated. In the current study, we investigated the cognitive resource account in three experiments. In Experiment 1, we manipulated task demands by adopting a detection or a localization task whilst both should allow global processing. In Experiments 2 and 3, we induced either a local or global perceptual processing strategy by presenting local or global targets (Experiment 2) or by priming local or global perception prior to the gaze cueing task (Experiment 3). Results showed faster orienting in response to a fearful face cue independent of task demands in Experiment 1. Inducing local and global processing strategies in Experiments 2 and 3 did not affect emotional modulation of the GCE. In contrast, Bayesian analyses provided evidence of absence of such an effect, demonstrating that local or global processing strategies cannot explain the mixed findings obtained in emotional modulation of gaze cueing.

Effect of race on Gaze Cueing in adults with high and low autistic traits

BackgroundObserving the direction of gaze of another person leads to shifting of attention in the same direction (gaze-cueing effect – GCE), a social-cognitive ability known as joint or social attention. Racial attitudes can influence the magnitude of GCE since it has been shown that White people showing a strong race ingroup preference follow the gaze only of White, and not Black, faces. Individuals with high autistic traits have difficulties in social-cognitive abilities that can disrupt the learning of socially shared racial attitudes. Our aim was to investigate in White Italian adults whether individuals with higher autistic traits (measured by the Autism Spectrum Quotient) show reduced implicit racial bias (measured by the Implicit Association Test) and if this bias would lead to differences in the gaze cueing effect (GCE) triggered by gaze direction of faces of different races (measured by the Gaze Cueing Task).MethodsIn an online study, participants (N = 165; 132 females; Mean age = 22.9; SD = 4.76) filled in the Autism Spectrum Quotient (AQ) questionnaire, then performed a Gaze Cueing Task, followed and by an Implicit Association Test.ResultsLinear regression and linear mixed model analyses showed in the IAT task the presence of the same implicit ingroup bias for all participants, which was not predicted by the AQ score, while in the Gaze Cueing Task the GCE differed depending on the AQ score of the participants. Specifically, participants with low-medium, medium, and medium–high autistic traits (AQ = -1SD; AQ = mean; AQ = + 1SD respectively) presented the GCE for both ingroup and outgroup cueing faces, whereas participants with high autistic traits (AQ = + 2SD) only for ingroup faces.ConclusionsIn White Italian adults the presence of an implicit ingroup bias seems to influence the GCE, but it is not always true that the individuals showing an implicit ingroup bias do not orient their attention in the direction of gaze of the outgroup individuals. Instead, the GCE seems to be modulated by the level of autistic traits. That is, individuals with higher autistic traits seem to prioritize joint attention with only their ingroup members.

Individual differences in gaze-cuing effect are associated with facial emotion recognition and social conformity.

Spontaneous gaze following and the concomitant joint attention enable us to share representations of the world with others, which forms a foundation of a broad range of social cognitive processes. Although this form of social orienting has long been suggested as a critical starting point for the development of social and communicative behavior, there is limited evidence directly linking it to higher-level social cognitive processes among healthy adults. Here, using a gaze-cuing paradigm, we examined whether individual differences in gaze following tendency predict higher-order social cognition and behavior among healthy adults. We found that individuals who showed greater gaze-cuing effect performed better in recognizing others' emotion and had greater tendency to conform with group opinion. These findings provide empirical evidence supporting the fundamental role of low-level socio-attentional processes in human sociality.

Face mask reduces gaze-cueing effect

Recent studies have found that face masks affect social cognition and behaviour in the context of the novel coronavirus (COVID-19) pandemic. The eyes, the only part of the face not covered by face masks, are an important spatial attention cue that can trigger social attention orienting. Here, we adopted a spatial gaze-cueing task to investigate whether face masks affect social attention orienting triggered by eye gaze cues. In Experiment 1, participants were asked to determine the orientation of a target line under two types of cues—masked and non-masked faces—and two stimulus onset asynchrony (SOA) conditions (300 ms and 1000 ms). The results showed that masked faces induced a smaller gaze-cueing effect (GCE) compared to non-masked faces at 300 ms SOA, while two face types induced similar GCEs at 1000 ms SOA. Experiment 2 used mouth-obscured faces and non-masked faces as cues and found that no significant difference in GCE between the two types at either 300 ms or 1000 ms SOA, indicating that the reduction of GCE caused by the masked face was due to the social meaning expressed by the mask rather than a physical effect of masking. The present study extends previous findings to support the idea that high-level social information affects the processing of eye gaze direction and provides evidence that face masks affect social cognition and behaviour in the context of COVID-19.

Cultural differences in joint attention and engagement in mutual gaze with a robot face

Joint attention is a pivotal mechanism underlying human ability to interact with one another. The fundamental nature of joint attention in the context of social cognition has led researchers to develop tasks that address this mechanism and operationalize it in a laboratory setting, in the form of a gaze cueing paradigm. In the present study, we addressed the question of whether engaging in joint attention with a robot face is culture-specific. We adapted a classical gaze-cueing paradigm such that a robot avatar cued participants’ gaze subsequent to either engaging participants in eye contact or not. Our critical question of interest was whether the gaze cueing effect (GCE) is stable across different cultures, especially if cognitive resources to exert top-down control are reduced. To achieve the latter, we introduced a mathematical stress task orthogonally to the gaze cueing protocol. Results showed larger GCE in the Singapore sample, relative to the Italian sample, independent of gaze type (eye contact vs. no eye contact) or amount of experienced stress, which translates to available cognitive resources. Moreover, since after each block, participants rated how engaged they felt with the robot avatar during the task, we observed that Italian participants rated as more engaging the avatar during the eye contact blocks, relative to no eye contact while Singaporean participants did not show any difference in engagement relative to the gaze. We discuss the results in terms of cultural differences in robot-induced joint attention, and engagement in eye contact, as well as the dissociation between implicit and explicit measures related to processing of gaze.

Gaze cueing in older and younger adults is elicited by a social robot seen from the back

The ability to follow the gaze of others deteriorates with age. This decline is typically tested with gaze cueing tasks, in which the time it takes to respond to targets on a screen is faster when they are preceded by a facial cue looking in the direction of the target (i.e., gaze cueing effect). It is unclear whether age-related differences in this effect occur with gaze cues other than the eyes, such as head orientation, and how these vary in function of the cue-target timing. Based on the perceived usefulness of social robots to assist older adults, we asked older and young adults to perform a gaze cueing task with the head of a NAO robot as the central cue. Crucially, the head was viewed from the back, and so its eye gaze was conveyed. In a control condition, the head was static and faced away from the participant. The stimulus onset asynchrony (SOA) between cue and target was 340 ms or 1000 ms. Both age groups showed a gaze cueing effect at both SOAs. Older participants showed a reduced facilitation effect (i.e., faster on congruent gazing trials than on neutral trials) at the 340-ms SOA compared to the 1000-ms SOA, and no differences between incongruent trials and neutral trials at the 340-ms SOA. Our results show that a robot with non-visible eyes can elicit gaze cueing effects. Age-related differences in the other effects are discussed regarding differences in processing time.

Can the robot "see" what I see? Robot gaze drives attention depending on mental state attribution.

Mentalizing, where humans infer the mental states of others, facilitates understanding and interaction in social situations. Humans also tend to adopt mentalizing strategies when interacting with robotic agents. There is an ongoing debate about how inferred mental states affect gaze following, a key component of joint attention. Although the gaze from a robot induces gaze following, the impact of mental state attribution on robotic gaze following remains unclear. To address this question, we asked forty-nine young adults to perform a gaze cueing task during which mental state attribution was manipulated as follows. Participants sat facing a robot that turned its head to the screen at its left or right. Their task was to respond to targets that appeared either at the screen the robot gazed at or at the other screen. At the baseline, the robot was positioned so that participants would perceive it as being able to see the screens. We expected faster response times to targets at the screen the robot gazed at than targets at the non-gazed screen (i.e., gaze cueing effect). In the experimental condition, the robot's line of sight was occluded by a physical barrier such that participants would perceive it as unable to see the screens. Our results revealed gaze cueing effects in both conditions although the effect was reduced in the occluded condition compared to the baseline. These results add to the expanding fields of social cognition and human-robot interaction by suggesting that mentalizing has an impact on robotic gaze following.

Linguistic identity as a modulator of gaze cueing of attention

Eye-gaze stimuli can elicit orienting of attention in an observer, a phenomenon known as gaze cueing of attention. Here, we explored whether gaze cueing can be shaped by the linguistic identity of the cueing face. In two experiments, participants were first familiarized with different faces together with auditory sentences. Half of the sentences were associated with the native language of the participants (Italian) and the other half with an unknown language (Albanian and Basque, in Experiments 1 and 2, respectively). In a second phase, participants performed a gaze-cueing task. In a third recognition phase, the auditory sentences were presented again, and participants were required to decide which face uttered each sentence. Results indicated that participants were more likely to confuse faces from the same language category than from the other language category. Results of the gaze-cueing task revealed a greater gaze-cueing effect for faces associated with the native vs. unknown language. Critically, this difference emerged only in Experiment 1, which may reflect differences in social status between the two language groups. Our findings revealed the impact of language as a social cue on the gaze-cueing effect, suggesting that social attention is sensitive to the language of our interlocutors.

Uncovering the cognitive mechanisms underlying the gaze cueing effect.

The gaze cueing effect is the tendency for people to respond faster to targets appearing at locations gazed at by others, compared with locations gazed away from by others. The effect is robust, widely studied, and is an influential finding within social cognition. Formal evidence accumulation models provide the dominant theoretical account of the cognitive processes underlying speeded decision-making, but they have rarely been applied to social cognition research. In this study, using a combination of individual-level and hierarchical computational modelling techniques, we applied evidence accumulation models to gaze cueing data (three data sets total, N = 171, 139,001 trials) for the first time to assess the relative capacity that an attentional orienting mechanism and information processing mechanisms have for explaining the gaze cueing effect. We found that most participants were best described by the attentional orienting mechanism, such that response times were slower at gazed away from locations because they had to reorient to the target before they could process the cue. However, we found evidence for individual differences, whereby the models suggested that some gaze cueing effects were driven by a short allocation of information processing resources to the gazed at location, allowing for a brief period where orienting and processing could occur in parallel. There was exceptionally little evidence to suggest any sustained reallocation of information processing resources neither at the group nor individual level. We discuss how this individual variability might represent credible individual differences in the cognitive mechanisms that subserve behaviourally observed gaze cueing effects.

Robot Gaze During Autonomous Navigation and Its Effect on Social Presence

As robots have become increasingly common in human-rich environments, it is critical that they are able to exhibit social cues to be perceived as a cooperative and socially-conformant team member. We investigate the effect of robot gaze cues on people’s subjective perceptions of a mobile robot as a socially present entity in three common hallway navigation scenarios. The tested robot gaze behaviors were path-oriented (looking at its own future path), or human-oriented (looking at the nearest person), with fixed-gaze as the control. We conduct a real-world study with 36 participants who walked through the hallway, and an online study with 233 participants who were shown simulated videos of the same scenarios. Our results suggest that the preferred gaze behavior is scenario-dependent. Human-oriented gaze behaviors which acknowledge the presence of the human are generally preferred when the robot and human cross paths. However, this benefit is diminished in scenarios that involve less implicit interaction between the robot and the human.

Head and body cues guide eye movements and facilitate target search in real-world videos.

Static gaze cues presented in central vision result in observer shifts of covert attention and eye movements, and benefits in perceptual performance in the detection of simple targets. Less is known about how dynamic gazer behaviors with head and body motion influence search eye movements and performance in perceptual tasks in real-world scenes. Participants searched for a target person (yes/no task, 50% presence), whereas watching videos of one to three gazers looking at a designated person (50% valid gaze cue, looking at the target). To assess the contributions of different body parts, we digitally erase parts of the gazers in the videos to create three different body parts/whole conditions for gazers: floating heads (only head movements), headless bodies (only lower body movements), and the baseline condition with intact head and body. We show that valid dynamic gaze cues guided participants' eye movements (up to 3 fixations) closer to the target, speeded the time to foveate the target, reduced fixations to the gazers, and improved target detection. The effect of gaze cues in guiding eye movements to the search target was the smallest when the gazer's head was removed from the videos. To assess the inherent information about gaze goal location for each body parts/whole condition, we collected perceptual judgments estimating gaze goals by a separate group of observers with unlimited time. Observers' perceptual judgments showed larger estimate errors when the gazer's head was removed. This suggests that the reduced eye movement guidance from lower body cueing is related to observers' difficulty extracting gaze information without the presence of the head. Together, the study extends previous work by evaluating the impact of dynamic gazer behaviors on search with videos of real-world cluttered scenes.

Effects of fearful face presentation time and observer’s eye movement on the gaze cue effect

BackgroundThere are many conflicting findings on the gaze cueing effect (GCE) of emotional facial expressions. This study aimed to investigate whether an averted gaze, accompanied by a fearful expression of different durations, could enhance attentional orientation, as measured by a participant’s eye movements.MethodsTwelve participants (3 females) completed the gaze cue task, reacting to a target location after observing changes in the gaze and expression of a face illustrated on a computer screen. Meanwhile, participants’ eye movements were monitored by electrooculography. The GCE was calculated by reaction time as an indicator of attention shift.ResultsThe analysis of the overall data did not find a significant effect of fearful facial expressions on the GCE. However, analysis of trial data that excluded a participant’s eye movement data showed that brief (0, 100 ms) presentation of the fearful facial expression enhanced the GCE compared to that during a neutral facial expression, although when the presentation time of the fearful expression was increased to 200 or 400 ms, the GCE of the fearful expression was at the same level as when model showed a neutral expression.ConclusionsThe results suggest that the attention-enhancing effect of gaze cues induced by rapidly presented fearful expressions occurs only when the effect of eye movement trials is excluded. This effect may be mediated by reflexively neural circuits in the amygdala that process threatening stimuli. However, as the expression duration increased, the fearful expression’s attention-enhancing effect decreased. We suggest that future studies on the emotion modulation of GCE should consider the negative effects of participants’ saccades and blinks on the experimental results.
