British study suggests surgeons, boxers and tennis players might benefit from watching films in stereoscope before taking on challenging tasks

A minority of filmgoers complain of dizziness and headaches, and previous studies have found that viewing in stereoscope offers no measurable improvement in enjoyment. But a new British study suggests that you may just improve your brain power by watching movies in 3D.

According to the research by Goldsmiths University neuroscientist Patrick Fagan and Professor Brendan Walker of Thrill Laboratory, participating filmgoers showed a 23% increase in cognitive processing ability after watching a movie in stereoscope. Their reaction times improved by 11%, and they experienced a “brain boost” for up to 20 minutes after viewing. The improvement in reaction time was five times that experienced by participants who had been watching a 2D movie.
