Since the effect was only observed with a live confederate, this provides evidence that we only use eye contact to signal approach if there is someone to approach and interact with.
Social interaction brief or continuous was more likely to be observed if mutual gaze or eye contact between dyads occurred once the participant entered the room. Continuous conversation was even more likely to occur if mutual gaze occurred a second time upon entry.
Alternatively, Cary found that the absence of mutual gaze upon entry predicted little to no social interaction between dyads. While this was an observational study, it does support the notion that it is the mutual exchange i. The intention to approach someone and socialize would be suitable for activating the nervous system within the first few seconds SCR , but we found here that eye contact maintains the heightened arousal response for the s duration SCL.
What signals could be sent and received on a continuous basis as to sustain an elevated level of arousal? In line with this, Conty et al. Also in line with this, Cavallo et al. Further analysis showed that there was an increase in connectivity between the IFG and arMPFC during live eye contact, suggesting that it triggers a network of brain regions involved in the detection of communicative intentions and language.
Similarly, a desynchronization of alpha-band activity was observed when infants looked at an object together with an adult during a social interaction involving eye contact Hoehl et al. No such effect was observed when infants and adults were not engaged in eye contact.
Thus, it is likely that the received gaze signals that we refer to in our study are analogous to these mentalizing processes, such that we are continually interpreting others gaze to understand their intentions, desires, beliefs, and knowledge Conty et al. It is also likely that the sent gaze signals are related more to an increase is self-awareness Conty et al. For example, if we are lying, we might conceal gaze signals to not show the truth.
Or if we are angry or sad, we might avoid gaze with others as to hide our feelings that could be communicated unwillingly through eye contact. Altogether, our findings contribute to the previous literature by showing that arousal is elicited most strongly in the first 10 s during eye gaze if it is clear that the eyes are looking back consistent with Watching Eyes model stage 1 , and then the individual maintains a high level of arousal for the duration of the eye gaze, likely in response to mentalizing processes self-reference, self-monitoring, communication, etc.
This arousal pattern elicited in the clear condition, but once the gaze signals could not be interpreted clearly, like when someone wears sunglasses in the degraded condition, arousal dropped back down to baseline levels after about 30 s. Baron-Cohen, Measuring the behavior of two live participants, while rich in data, is not without its limitations. For instance, participants who wore the sunglasses participant B verbally mentioned that they were uncertain of the extent to which the sunglasses disguised their eyes to the other participant.
Based on informal conversations, the majority of participants who wore the sunglasses assumed their eyes were quite visible and thus, they would believe they could send gaze information to the other person.
However, this should have been consistent with every participant either believing that their eyes were visible or not. Another potential limitation was the within-subjects design, such that participants took part in all three conditions—clear, degraded, and blocked.
While the order of conditions was counterbalanced, previous unpublished research in our lab has shown that participants habituate to eye contact over time and show less and less arousal with repeated exposure.
Thus, our data may have been stronger if we had enough participants to analyze the data as a between-subjects design. Since both participants were expected to have no ability to send or receive gaze information, no differences in the SCR between partners were expected to emerge in the eye contact trials. As mentioned in the results, there was a difference between participants arousal levels within the blindfold condition, such that participant B wearing the blindfold showed significantly higher arousal across all gaze trials.
The current study demonstrated that arousal from eye contact is associated with the sending and receiving of gaze signals, and as the ability to exchange gaze signals decreases by degrading the visibility of the eyes with sunglasses or a blindfold , so does arousal and the possibility for social interaction.
We also tried to rule out the argument that arousal from eye contact is due to the saliency of the eyes by demonstrating no arousal enhancement when participants made eye contact with themselves in a mirror. These findings could have implications for individuals who wear sunglasses in our everyday life.
This lack of gaze information could hinder the communicative process by decreasing arousal and in turn reduce attention to, interest in, and excitement for what is being said. That is, they might be trying to conceal their eyes in order to reduce the gaze signals of approach. On the other hand, if you wish to engage in riveting social interaction, then perhaps sunglasses should be avoided.

Hessels, R. They suggest the following tips to help maintain good eye contact without staring:. This article is the third and last in a series of articles that examined eye contact in communication. Remember that eye contact is a skill and it often takes time and practice to fine-tune our skills. This article was published by Michigan State University Extension. This helps to display interest and confidence. Maintain it for seconds. Once you establish eye contact, maintain or hold it for seconds.
After this time passes, you can slowly glance to the side and then go back to establishing eye contact. However, when you look away, do it slowly without darting your eyes. This can make you look shy or nervous. This has led to debate about whether faces with more dilated pupils sometimes taken as a sign of sexual interest are perceived by onlookers to be more attractive.

But when you look another person deep in the eye, do not think it is just their pupils sending you a message. Other recent research suggests that we can read complex emotions from the eye muscles — that is, whether a person is narrowing or opening their eyes wide. Yet another important eye feature are limbal rings: the dark circles that surround your irises. Recent evidence suggests that these limbal rings are more often visible in younger, healthier people, and that onlookers know this on some level, such that heterosexual women looking for a short-term fling judge men with more visible limbal rings to be more healthy and desirable.

All these studies suggest there is more than a grain of truth to the old adage about the eyes being a window to the soul. They say that our eyes are the only part of our brain that is directly exposed to the world.
It's worried over by those on job interviews, on dates, and negotiating. People who hold eye contact too long are seen as aggressive, and people who hold eye contact too short, as shifty. If you get it wrong, you can give off more than just signals of social awkwardness. Autism and schizophrenia are both partially diagnosed by eye contact abnormalities.
So what is normal? Just this week, Royal Open Science published the first study of what "normal" eye contact looks like.
