"Recent studies in different labs, including here at the University of Toronto, have shown that playing first-person shooter videogames can enhance other aspects of visual attention. But no one has previously demonstrated that visual search is also improved," said psychology professor Ian Spence.
Searching efficiently and accurately is essential for many tasks.
"It's necessary for baggage screening, reading X rays or MRIs, interpreting satellite images, defeating camouflage or even just locating a friend's face in a crowd," noted Spence.
In the first experiment, the researchers compared action videogame players and non-players on three visual search tasks and found that the experienced players were better.
"But this difference could be a result of a pre-existing superiority in experienced gamers compared to those who avoid them," said Sijing Wu, a PhD candidate in Spence's lab in U of T's Department of Psychology and lead author of the study.
"A training experiment was necessary to establish whether playing an action game could actually improve search skills," Wu asserted.
In the second experiment, 60 participants - who had not previously played videogames - played for a total of 10 hours in one to two hour sessions. Twenty participants were randomly assigned to play the first-person shooter game, Medal of Honor, 20 to a driving-racing game, Need for Speed and 20 to a three-dimensional puzzle game, Ballance as a control.
"After playing either the shooter or driving game for only 10 hours, participants were faster and more accurate on the three visual search tasks," said Wu.
However, the control participants - who played the puzzle game - did not improve, the researcher said.
"We have shown that playing a driving-racing game can produce the same benefits as a shooter game. This could be very important in situations where we wish to train visual search skills. Driving games are likely to be more acceptable than shooting games because of the lower levels of violence," Wu concluded.
