Learning under your gaze: the mediating role of affective arousal between perceived direct gaze and memory performance

Previous studies have shown that cognitive performance can be affected by the presence of an observer and self-directed gaze. We investigated whether the effect of gaze direction (direct vs. downcast) on verbal memory is mediated by autonomic arousal. Male participants responded with enhanced affective arousal to both male and female storytellers’ direct gaze which, according to a path analysis, was negatively associated with the performance. On the other hand, parallel to this arousal-mediated effect, males’ performance was affected by another process impacting the performance positively and suggested to be related to effort allocation on the task. The effect of this process was observed only when the storyteller was a male. The participants remembered more details from a story told by a male with a direct vs. downcast gaze. The effect of gaze direction on performance was the opposite for female storytellers, which was explained by the arousal-mediated process. Surprisingly, these results were restricted to male participants only and no effects of gaze were observed among female participants. We also investigated whether the participants’ belief of being seen or not (through an electronic window) by the storyteller influenced the memory and arousal, but this manipulation had no effect on the results.     

When one sees what the other hears: Crossmodal attentional modulation for gazed and non-gazed upon auditory targets

Three experiments investigated the nature of visuo-auditory crossmodal cueing in a triadic setting: participants had to detect an auditory signal while observing another agent’s head facing one of the two laterally positioned auditory sources. Experiment 1 showed that when the agent’s eyes were open, sounds originating on the side of the agent’s gaze were detected faster than sounds originating on the side of the agent’s visible ear; when the agent’s eyes were closed this pat-tern of responses was reversed. Two additional experiments showed that the results were sensitive to whether participants could infer a hearing function on the part of the agent. When no ear was depicted on the agent, only a gaze-side advantage was observed (Experiment 2), but when the agent’s ear was covered (Experiment 3), an ear side advantage was observed only when hearing could still be inferred (i.e., wearing the hat) but not when hearing was inferred to be diminished (i.e., wearing a helmet). The findings are discussed in the context of inferential and simulation processes and joint attention mechanisms.     

Social influence on metacognitive evaluations: The power of nonverbal cues

Metacognitive evaluations refer to the processes by which people assess their own cognitive operations with respect to their current goal. Little is known about whether this process is susceptible to social influence. Here we investigate whether nonverbal social signals spontaneously influence metacognitive evaluations. Participants performed a two-alternative forced-choice task, which was followed by a face randomly gazing towards or away from the response chosen by the participant. Participants then provided a metacognitive evaluation of their response by rating their confidence in their answer. In Experiment 1, the participants were told that the gaze direction was irrelevant to the task purpose and were advised to ignore it. The results revealed an effect of implicit social information on confidence ratings even though the gaze direction was random and therefore unreliable for task purposes. In addition, nonsocial cues (car) did not elicit this effect. In Experiment 2, the participants were led to believe that cue direction (face or car) reflected a previous participant's response to the same question—that is, the social information provided by the cue was made explicit, yet still objectively unreliable for the task. The results showed a similar social influence on confidence ratings, observed with both cues (car and face) but with an increased magnitude relative to Experiment 1. We additionally showed in Experiment 2 that social information impaired metacognitive accuracy. Together our results strongly suggest an involuntary susceptibility of metacognitive evaluations to nonverbal social information, even when it is implicit (Experiment 1) and unreliable (Experiments 1 and 2).     

Seductive eyes: attractiveness and direct gaze increase desire for associated objects

Recent research in neuroscience shows that observing attractive faces with direct gaze is more rewarding than observing attractive faces with averted gaze. On the basis of this research, it was hypothesized that object evaluations can be enhanced by associating them with attractive faces displaying direct gaze. In a conditioning paradigm, novel objects were associated with either attractive or unattractive female faces, either displaying direct or averted gaze. An affective priming task showed more positive automatic evaluations of objects that were paired with attractive faces with direct gaze than attractive faces with averted gaze and unattractive faces, irrespective of gaze direction. Participants' self-reported desire for the objects matched the affective priming data. The results are discussed against the background of recent findings on affective consequences of gaze cueing.     

Who is watching Big Brother? TV consumption predicted by masked affective priming

In the present study (N=37), we assessed attitudes towards a telecast (Big Brother) with indirect (masked affective priming) and direct (semantic differentials) methods. Additionally, participants recorded their TV viewing behaviour for a period of 7 days. Implicit positivity of the telecast (assessed by the affective priming task), explicit positivity (semantic differentials), and minutes per week spent viewing the TV show were all positively correlated. Viewers of the telecast show a positive priming effect for the label of the telecast (thereby indicating a positive implicit attitude towards the show). Implications for the research and the theoretical debate on implicit attitudes are discussed. Copyright © 2003 John Wiley & Sons, Ltd.     

Predicting Self‐Confident Behaviour with Implicit and Explicit Self‐Esteem Measures

The present research compared the validity of popular direct and indirect measures of self‐esteem in predicting self‐confident behaviour in different social situations. In line with behavioural dual‐process models, both implicit and explicit self‐esteem were hypothesized to be related to appearing self‐confident to unacquainted others. A total of 127 participants responded to the Rosenberg Self‐Esteem Scale, the Multidimensional Self‐Esteem Scale, and an adjective scale for measuring explicit self‐esteem (ESE). Participants' implicit self‐esteem (ISE) was assessed with four indirect measures: the Implicit Association Test (IAT), the name‐letter task (NLT), and two variants of an affective priming task, the reaction‐time affective priming task (RT‐APT) and the error‐based affective priming task (EB‐APT). Self‐confident behaviour was observed in four different social situations: (i) self‐introduction to a group; (ii) an ostracism experience; (iii) an interview about the ostracism experience; and (iv) an interview about one's personal life. In general, appearing self‐confident to unknown others was independently predicted by ESE and ISE. The indirect measures of self‐esteem were, as expected, not correlated, and only the self‐esteem APTs—but not the self‐esteem IAT or the NLT—predicted self‐confident behaviours. It is important to note that in particular the predictive power of the self‐esteem EB‐APT pertained to all four criteria and was incremental to the ESE measures.

Nervous Instability and Genius: Military and Political Leaders

Participants (N = 106) performed an affective priming task with facial primes that varied in their skin tone and facial physiognomy, and, which were presented either in color or in gray-scale. Participants' racial evaluations were more positive for Eurocentric than for Afrocentric physiognomy faces. Light skin tone faces were evaluated more positively than dark skin tone faces, but the magnitude of this effect depended on the mode of color presentation. The results suggest that in affective priming tasks, faces might not be processed holistically, and instead, visual features of facial priming stimuli independently affect implicit evaluations.     

Make the manikin move: Symbolic approach–avoidance responses affect implicit and explicit face evaluations

The present research aimed to replicate and extend findings of Huijding, Muris, Lester, Field, and Joosse (2011), investigating whether symbolic approach–avoidance responses can induce implicit and explicit evaluation biases. Faces with a neutral expression were shown on a computer screen, and participants were instructed to repeatedly move a manikin towards some faces (approach) and away from other faces (avoidance). An affective priming task and a face rating task were used to assess training-compatible differences in implicit and explicit face evaluations, respectively. Results showed that the manikin training was successful: The priming task revealed more positive implicit evaluations of approached than avoided faces, and approached faces were rated more positively than avoided ones in the face rating task. These findings replicate those of Huijding and colleagues by demonstrating training effects on explicit evaluations, and they extend them by demonstrating effects on implicit evaluations.     

I just love the attention: implicit preference for direct eye contact

Seven studies used the Implicit Association Test to measure preference for gaze direction. For faces with neutral expressions, people clearly preferred eyes looking towards them compared to eyes gazing to the right or left (Experiment 1). This preference remained for faces shown turned to the side (Experiment 2) and upside-down (Experiment 3). Even angry faces were preferred with direct compared to averted gaze (Experiments 4 and 5). Furthermore, preference for eye contact did not correlate to performance on the Reading the Mind in the Eyes Test (RMET) or the Autism Quotient (AQ); note performance on the RMET and the AQ was only weakly correlated although both are claimed to measure social cognition. When the faces were replaced by coloured shapes (Experiment 6) or arrows (Experiment 7) people showed a weaker preference for the category label “looking at you” versus “looking to the side”. Overall, people revealed a robust preference for direct rather than averted gaze which generalized across face pose and expression. Together with a weaker preference for arrows pointing towards them, this is consistent with people having an implicit preference for self-directed attention.     

What are you looking at? Acuity for triadic eye gaze

The authors measured observers' ability to determine direction of gaze toward an object in space. In Experiment 1, they determined the difference threshold for determining whether a live "looker" was looking to the left or right of a target point. Acuity for eye direction was quite high (approximately 30 s arc). Viewing the movement of the looker's eyes did not improve acuity. When one of the looker's eyes was occluded, the observers' acuity was disrupted and their point of subjective equality was shifted away from the exposed eye. Experiment 2 was a replication of Experiment 1, but digitized gaze displays were used. The results of Experiment 3 showed that the acuity for direction of gaze depended on the position of the looker's target. Overall, the results indicated that humans are highly sensitive to gaze direction and that information from both eyes is used to determine direction of regard.     

Facing away from the interviewer: Evidence of little benefit to eyewitnesses' memory performance

Averting gaze from another person's face generally improves cognitive performance, yet, little is known about how witnesses' gaze direction affects their recall during investigative interviews. Here, participants witnessed a video-recorded incident, and were interviewed via free recall and closed questions following a short delay. In Experiment 1, participants either faced the interviewer or faced away during the interview. In Experiment 2, alongside this manipulation, the interviewer also either faced the witness or faced away. In Experiment 3, witness gaze direction was manipulated alongside rapport-building. In Experiment 4, the effect of facing away was directly compared with that of eye-closure. Mini meta-analysis of all four experiments showed that the effect of witness gaze direction on memory performance was minimal. Furthermore, neither aversion of interviewer's gaze nor rapport-building magnified this effect. Added to the cumulative literature on eyewitness gaze aversion, these findings afford better estimates of the likely size of these effects.     

The combined effect of gaze direction and facial expression on cueing spatial attention

Empirical evidence shows an effect of gaze direction on cueing spatial attention, regardless of the emotional expression shown by a face, whereas a combined effect of gaze direction and facial expression has been observed on individuals' evaluative judgments. In 2 experiments, the authors investigated whether gaze direction and facial expression affect spatial attention depending upon the presence of an evaluative goal. Disgusted, fearful, happy, or neutral faces gazing left or right were followed by positive or negative target words presented either at the spatial location looked at by the face or at the opposite spatial location. Participants responded to target words based on affective valence (i.e., positive/negative) in Experiment 1 and on letter case (lowercase/uppercase) in Experiment 2. Results showed that participants responded much faster to targets presented at the spatial location looked at by disgusted or fearful faces but only in Experiment 1, when an evaluative task was used. The present findings clearly show that negative facial expressions enhance the attentional shifts due to eye-gaze direction, provided that there was an explicit evaluative goal present.     

Eye remember you: the effects of gaze direction on face recognition in children and adults

Children and adults were tested on a forced‐choice face recognition task in which the direction of eye gaze was manipulated over the course of the initial presentation and subsequent test phase of the experiment. To establish the effects of gaze direction on the encoding process, participants were presented with to‐be‐studied faces displaying either direct or deviated gaze (i.e. encoding manipulation). At test, all the faces depicted persons with their eyes closed. To investigate the effects of gaze direction on the efficiency of the retrieval process, a second condition (i.e. retrieval manipulation) was run in which target faces were presented initially with eyes closed and tested with either direct or deviated gaze. The results revealed the encoding advantages enjoyed by faces with direct gaze was present for both children and adults. Faces with direct gaze were also recognized better than faces with deviated gaze at retrieval, although this effect was most pronounced for adults. Finally, the advantage for direct gaze over deviated gaze at encoding was greater than the advantage for direct gaze over deviated gaze at retrieval. We consider the theoretical implications of these findings.     

Implicit memory for novel conceptual associations in amnesia

In two experiments, we evaluated the status of implicit memory for novel associations in amnesia. Experiment 1 assessed priming in a category exemplar generation task in which contextual information associated with a target could increase the likelihood of target generation. Control participants, but not amnesic patients, showed associative priming. Amnesics’ impairment was not due to the use of explicit memory by control subjects but reflected a genuine impairment in implicit memory for novel conceptual associations. Experiment 2 assessed priming in a relatedness judgment task, in which associative priming was manifest as longer latencies for old than for recombined pairs of unrelated words. Amnesic patients showed intact associative priming in this task. We discuss differences in the status of implicit memory for novel conceptual associations in amnesia, with reference to the nature of the representation that supports priming in the two tasks and the type of processing that is required at test.     

Eye remember you two: gaze direction modulates face recognition in a developmental study

The effects of gaze direction on memory for faces were studied in children from three different age groups (6-7, 8-9, and 10-11 years old) using a computerized version of a task devised by Hood, Macrae, Cole-Davies and Dias (2003). Participants were presented with a sequence of faces in an encoding phase, and were then required to judge which faces they had previously encountered in a surprise two-alternative forced-choice recognition test. In one condition, stimulus eye gaze was either direct or deviated at the viewing phase, and eyes were closed at the test phase. In another condition, stimulus eyes were closed at the viewing phase, with either direct or deviated gaze at the test phase. Modulation of gaze direction affected hit rates, with participants demonstrating greater accuracy for direct gaze targets compared to deviated gaze targets in both conditions. Reaction times (RT) to correctly recognized stimuli were faster for direct gaze stimuli at the viewing phase, but not at the test phase. The age group of participants differentially affected these measures: there was a greater hit rate advantage for direct gaze stimuli in older children, although RTs were less affected by age. These findings suggest that while the facilitation of face recognition by gaze direction is robust across encoding and recognition stages, the efficiency of the process is affected by the stage at which gaze is modulated.     

他人注视对不诚实行为的影响

有研究发现,他人的注视会使人们倾向于遵循社会规则,但甚少发现他人注视状态对不诚实行为的影响。该研究旨在通过比较眼睛的呈现类型和形式对不诚实行为的影响,来考察哪种注视状态能有效抑制个体的不诚实行为。结果发现,非伴随注视状态下,被试表现出不诚实行为,且不同类型的眼睛对被试的不诚实行为没有影响; 伴随注视状态下,直视眼抑制了被试的不诚实行为,而斜视眼则没有。这表明他人持续的注视可能作为内隐的名誉线索在一定程度上抑制了人们的不诚实行为。     

The influence of head contour and nose angle on the perception of eye-gaze direction

We report seven experiments that investigate the influence that head orientation exerts on the perception of eye-gaze direction. In each of these experiments, participants were asked to decide whether the eyes in a brief and masked presentation were looking directly at them or were averted. In each case, the eyes could be presented alone, or in the context of congruent or incongruent stimuli In Experiment 1A, the congruent and incongruent stimuli were provided by the orientation of face features and head outline. Discrimination of gaze direction was found to be better when face and gaze were congruent than in both of the other conditions, an effect that was not eliminated by inversion of the stimuli (Experiment 1B). In Experiment 2A, the internal face features were removed, but the outline of the head profile was found to produce an identical pattern of effects on gaze discrimination, effects that were again insensitive to inversion (Experiment 2B) and which persisted when lateral displacement of the eyes was controlled (Experiment 2C). Finally, in Experiment 3A, nose angle was also found to influence participants' ability to discriminate direct gaze from averted gaze, but here the effect was eliminated by inversion of the stimuli (Experiment 3B). We concluded that an image-based mechanism is responsible for the influence of head profile on gaze perception, whereas the analysis of nose angle involves the configural processing of face features.     

Straight gaze facilitates face processing but does not cause involuntary attentional capture

This study aimed to investigate the conditions under which eyes with a straight gaze capture attention more than eyes with an averted gaze, a phenomenon called the stare-in-the-crowd effect. In Experiment 1, we measured attentional capture by distractor faces with either straight or averted gaze that were shown among faces with closed eyes. Gaze direction of the distractor face was irrelevant because participants searched for a tilted face and indicated its gender. The presence of the distractor face with open eyes resulted in slower reaction times, but gaze direction had no effect, suggesting that straight gaze does not result in more involuntary attentional capture than averted gaze. In three further experiments with the same stimuli, the gaze direction of the target, and not the distractor, was varied. Better performance with straight than averted gaze of the target face was observed when the gaze direction or gender of the target face had to be discriminated. However, no difference between straight and averted was observed when only the presence of a face with open eyes had to be detected. Thus, the stare-in-the crowd effect is only observed when eye gaze is selected as part of the target and only when features of the face have to be discriminated. Our findings suggest that preference for straight gaze bears on target-related processes rather than on attentional capture per se.     

Looking at others through implicitly or explicitly prejudiced eyes

It is well known that we utilize internalized representations (or schemas) to direct our eyes when exploring visual stimuli. Interestingly, our schemas for human faces are known to reflect systematic differences that are consistent with one's level of racial prejudice. However, whether one's level or type of racial prejudice can differentially regulate how we visually explore faces that are the target of prejudice is currently unknown. Here, White participants varying in their level of implicit or explicit prejudice viewed Black faces and White faces (with the latter serving as a control) while having their gaze behaviour recorded with an eye-tracker. The results show that, regardless of prejudice type (i.e., implicit or explicit), participants high in racial prejudice examine faces differently than those low in racial prejudice. Specifically, individuals high in explicit racial prejudice were more likely to fixate on the mouth region of Black faces when compared to individuals low in explicit prejudice, and exhibited less consistency in their scanning of faces irrespective of race. On the other hand, individuals high in implicit racial prejudice tended to focus on the region between the eyes, regardless of face race. It therefore seems that racial prejudice guides target-race specific patterns of looking behaviour, and may also contribute to general patterns of looking behaviour when visually exploring human faces.     

Locus of Control and Implicit Memory

Two experiments were conducted to investigate the influence of locus of control on implicit and explicit memory. We hypothesized that internals would rely on semantic processing, externals on perceptual processing. In Experiment 1, 80 college students studied 36 words and completed an implicit memory test in either a consistent or cross-modality condition. The results revealed that externals had higher priming scores than did internals, regardless of modality. In Experiment 2, 80 college students took either an implicit or explicit test. The results again revealed that externals showed higher priming scores than internals. The higher priming scores exhibited by the externals do not necessarily mean that they are more perceptually oriented than the internals are.
