A virtual reality experience of being in Albert Einstein's body can help people with low self-esteem score better on cognitive tests, a study has found. Following a virtual reality "Einstein" experience, participants were also less likely to unconsciously stereotype older people. The study, which was published in Frontiers in Psychology, suggests the way our brain perceives our body is surprisingly flexible. The researchers hope the technique can contribute to education technology.
"Virtual reality can create the illusion of a virtual body to substitute your own, which is called virtual embodiment," said Mel Slater, a professor at the University of Barcelona in Spain. "In an immersive virtual environment, participants can see this new body reflected in a mirror and it exactly matches their movements, helping to create a powerful illusion that the virtual body is their own," said Slater.
Previous research found that virtual embodiment can have striking effects on attitudes and behaviour. For example, white people who experienced a virtual black body showed less unconscious stereotyping (called implicit bias) of black people. "We wondered whether virtual embodiment could affect cognition. If we gave someone a recognizable body that represents supreme intelligence, such as that of Albert Einstein, would they perform better on a cognitive task than people given a normal body?" said Slater.
To find out, the researchers recruited 30 young men to participate in a virtual embodiment experiment. Prior to the embodiment, the participants completed three tests: a cognitive task to reveal their planning and problem-solving skills; a task to quantify their self-esteem; and one to identify any implicit bias towards older people.
This final task was to investigate whether the experience of having an older appearance simulation could change attitudes to older people. The study participants then donned a body-tracking suit and a virtual reality headset. Half experienced a virtual Einstein body and the other half a normal adult body. After completing some exercises in the virtual environment with their new body, they repeated the implicit bias and cognitive tests.
The researchers found that people with low self-esteem performed the cognitive task better following the virtual Einstein experience, compared with those who experienced a normal body of someone their own age. Those exposed to the Einstein body also had a reduced implicit bias against older people.
Crucially, cognitive enhancements only occurred in people with low self-esteem. The researchers hypothesised that those with low self-esteem had the most to gain by changing how they thought about themselves.
Seeing themselves in the body of a respected and intelligent scientist may have enhanced their confidence during the cognitive test.
