Adults become more like children in a virtual world

In a virtual world adults in a child-like body start to perceive the world more like a child, a study has shown.

Adults were either placed in a virtual four-year-old body or an adult body scaled down to the same size.

It was found that participants in the child's body overestimated the size of objects and identified better with child-like attributes.

Scientists say their work, published in PNAS, could help unlock hidden memories.

Wearing a head mounted display and a motion capture suit that tracks body movements, adults were able to move in a virtual world just as they would in the real world.

Previous research has already shown that the brain is amenable to accepting such illusory changes. So if a person moves at the same time their virtual body does, they feel as if they are really moving.

A team led by Mel Slater from the University of Barcelona found three situations in which adult participants reacted differently depending on what virtual body they were in.
