Our Attention Is Captured by Eye-Glance

Summary: When people make eye contact with another person, their attention is immediately solicited and this causes a distortion in temporal perception. However, the shift in time perception does not change when people glance at non-social items or objects.

Eyes play an important role in social communication by expressing the intentions of our interlocutors, and even more so in times of pandemic when half of the face is hidden. But is this eye contact automatic and rapid? Is it based on a priority attentional reaction or, on the contrary, on a particular emotional reaction?

To answer these questions, researchers at the University of Geneva (UNIGE), Switzerland, looked at the way we process human gaze, focusing on the estimation of the temporal duration of social interactions.

They discovered that when we make eye contact with another person, our attention is directly solicited, causing a distortion in our temporal perception. As a result, time seems shorter than it really is. On the contrary, this underestimation of time does not occur when we look at a non-social object.

These results, in the journal Cognition, will make it possible to develop a diagnostic tool to evaluate the mechanisms at work in people who are sensitive to social gaze, and then to act accordingly if disorders in the processing of social stimuli are detected, for instance in the case of autism or schizophrenia.

The way we look at others and the way we perceive others’ gaze have a major impact on social communication, a fundamental function called social cognition.

“From an early age, we learn to decipher the feelings and intentions of our interlocutors through their eyes. Thus, meeting someone’s gaze is a very common social situation, but it always leads to a particular feeling”, notes Nicolas Burra, a researcher at the Psychology Section of the Faculty of Psychology and Educational Sciences (FPSE) at the UNIGE, and first author of the study.

Two hypotheses are put forward to describe this situation: one says that eye contact with others directly generates an emotional reaction, without passing through our attention.

The second hypothesis is that eye contact activates rapid and automatic attentional processing, which subsequently generates an emotional response.

Our perception of time influenced by emotion and attention

To test these hypotheses, the UNIGE researchers looked at the way we perceive time, which varies according to the emotional or attentional processing of the visual stimulus.

“Indeed, it has been shown that when our emotional capacities have to process an unpleasant visual stimulus, for example if we are asked to evaluate the time of the appearance of a large spider, we will overestimate the time that passes, giving the impression that it is flowing more quickly than it actually does”, explains Nicolas Burra.

Thus, our ability to evaluate time is disturbed by the emotional charge and accelerates. On the contrary, when the visual stimulus is processed by attention, the opposite effect occurs: focused on a stimulus that is very important for our attention, we underestimate the time that elapses and look at the object longer than we imagined.

“By analyzing how long a person estimates that he or she has been looking at an object, we can determine whether the eye contact between two people is more attention-seeking or emotion-seeking”, says the Geneva-based researcher.

Deviated gazes versus eye contact

To assess the impact of eye contact on our perception of time, 22 participants observed a series of nearly 300 faces moving their eyes: either gazes establishing direct eye contact – eyes look into the void and then catch the participant’s gaze – or deviated gazes – the same eye movement is made, but the face and the participant’s gaze never meet.

Over a period of 20 minutes, the participants subjectively assessed the different durations (between 1 and 2 seconds, close to everyday social interactions) of these social interactions.

“While deviated glances do not distort our perception of time, we found that, on the contrary, when glances crossed, the participants systematically underestimated the duration of these eye contacts”, says Nicolas Burra. This experiment reveals that eye contact does not primarily impact the emotional system, but rather the attentional system that distracts us from our ability to evaluate time.

To assess these results, the UNIGE researchers carried out the same experiment with other participants, using non-social objects that made the same movements as the gaze. In that case, no distortion of time perception was observed. The same was true when a face was static. “It seems that not only a gaze, but also a movement is required”, the neuroscientist points out.

The time-distortion effect was found, however, when the participants were shown only schematic eye movements or moving parts of the eyes without the rest of the face – a situation that is similar to social interaction with a mask.

But it goes further, because this effect was also found in an online experiment with a hundred people, corroborating and generalizing the results obtained in the laboratory.

Eye contact captures attention

This series of experiments shows that eye contact and social stimuli impacts attention, preferentially. “This explains the sensation we feel when someone looks at us even though we have not yet really met their gaze”, explains Nicolas Burra.

This work will make it possible to evaluate and then intervene more precisely on the attentional or emotional processes in people suffering from disorders in the processing of social stimuli, characterized by a lack of interest, a misinterpretation of the gaze or by an extreme emotional reaction to others’ gaze, such as in autistic people, schizophrenics or people suffering from social anxiety.

The research team is currently carrying out this experiment with children and elderly people, in order to observe the evolution of this preferential processing of eye contact by attention over the lifespan.

Nicolas Burra concludes: “This study gives meaning to the sensation that time stops when we meet another’s gaze.”

Meeting another’s gaze shortens subjective time by capturing attention” by Nicolas Burra, Dirk Kerzel. Cognition


Abstract

Meeting another’s gaze shortens subjective time by capturing attention

Gaze directed at the observer (direct gaze) is an important and highly salient social signal with multiple effects on cognitive processes and behavior. It is disputed whether the effect of direct gaze is caused by attentional capture or increased arousal.

Time estimation may provide an answer because attentional capture predicts an underestimation of time whereas arousal predicts an overestimation. In a temporal bisection task, observers were required to classify the duration of a stimulus as short or long. Stimulus duration was selected randomly between 988 and 1479 ms.

When gaze was directed at the observer, participants underestimated stimulus duration, suggesting that effects of direct gaze are caused by attentional capture, not increased arousal. Critically, this effect was limited to dynamic stimuli where gaze appeared to move toward the participant.

The underestimation was present with stimuli showing a full face, but also with stimuli showing only the eye region, inverted faces and high-contrast eye-like stimuli. However, it was absent with static pictures of full faces and dynamic nonfigurative stimuli.

Because the effect of direct gaze depended on motion, which is common in naturalistic scenes, more consideration needs to be given to the ecological validity of stimuli in the study of social attention.

  1. Sadly this is so wrong. There are “times” when time gets distorted from eye contact; usually the feeling is that more time has passed than has, not less. This is because when your eye is “randomly” caught by another person that person is someone you are unfamiliar with. You didn’t intend the eye contact it happened, and this is a stressful thing for most causing time to feel forever, not instant. Also, eye contact does not have to occur for two people to feel each other’s awareness of one another which has the same time effect without having made any actual eye contact. Additionally, if you do not care what the other may be thinking at all, absolutely no distortion takes place. It only happens when you are trying to get a read on another person. Nice attempt at an idea though. Do some real research and trial and error and you might actually have something worth sharing.
