Baku, May 23, AZERTAC Watching films in 3D exercises the brain, and improves short-term functioning in a similar way to brain-training tests, a group of scientists have claimed. An experiment led by a neuroscientist from Goldsmiths University in London has found that people who watch video in 3D have improved cognitive skills compared to those who watch in 2D. More than 100 people took part in an experiment where participants watched the Disney film Big Hero 6 in either standard format or RealD 3D, as well as carrying out a brain-training-style test before and after seeing a segment from the film. The test covered memory, reaction times and cognitive function, and the results were subsequently compared.
