People behave differently in virtual reality than they do in real life: Study

Date:

A new UBC research has found a huge gap between how people respond psychologically in VR and how they respond in real life.

The study, published January 22 in Scientific Reports sees lead author Alan Kingstone say that people expect virtual reality experiences to mimic actual reality and thus induce similar forms of thought and behaviour. However, he adds, “This study shows that there’s a big separation between being in the real world, and being in a virtual world.”

Researchers used virtual reality to examine factors that influence yawning — focusing specifically on contagious yawning. It is a well-documented phenomenon in which both people, and animals, yawn as a reflex when they detect a yawn nearby.

Earlier research has shown that when people believe they are being watched, they yawn less, or at least resist the urge. This may be due to the stigma of yawning in social settings, or its perception in many cultures as a sign of boredom or rudeness.

The team from UBC, along with Andrew Gallup from State University of New York Polytechnic Institute, tried to bring about contagious yawning in a VR environment. They had test subjects wear an immersive headset and exposed them to videos of people yawning. In those conditions, the rate of contagious yawning was 38 per cent, which is in line with the typical real-life rate of 30-60 per cent.

However, when the researchers introduced social presence in the virtual environment, they were surprised to find it had little effect on subjects’ yawning. Subjects yawned at the same rate, even while being watched by a virtual human avatar or a virtual webcam.

The study showed an interesting paradox: stimuli that trigger contagious yawns in real life did the same in virtual reality, but stimuli that suppress yawns in real life did not.

Notably, the presence of an actual person in the room had a more significant effect on yawning. Even though subjects couldn’t see or hear their company, simply knowing a researcher was present was enough to diminish their yawning. Social cues in actual reality appeared to dominate and supersede those in virtual reality.

Virtual reality has caught on as a research tool in psychology and other fields, but these findings show that researchers may need to account for its limitations.

Speaking about it, Kingston said that using VR to examine how people think and behave in real life may very well lead to conclusions that are fundamentally wrong. This has profound implications for people who hope to use VR to make accurate projections regarding future behaviours.

He further added, “For example, predicting how pedestrians will behave when walking amongst driverless cars, or the decisions that pilots will make in an emergency situation. Experiences in VR may be a poor proxy for real life.”

If the gap between VR and real life could be closed, scientists would be able to examine the link between the brain, behaviour, and the human experience in both actual reality and altered realities that span place and time, Kingstone added.
