Your brain on video games
Researchers at the 含羞草传媒 have shown that playing shooting or driving video games, even for a relatively short time, improves the ability to search for a target hidden among irrelevant distractions in complex scenes.
鈥淩ecent studies in different labs, including , have shown that playing first-person shooter videogames can enhance other aspects of visual attention,鈥 says psychology professor Ian Spence. 鈥淏ut no one has previously demonstrated that visual search is also improved.鈥
Searching efficiently and accurately is essential for many tasks. 鈥淚t鈥檚 necessary for baggage screening, reading X鈥憆ays or MRIs, interpreting satellite images, defeating camouflage or even just locating a friend鈥檚 face in a crowd,鈥 says 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.
鈥淏ut this difference could be a result of a pre-existing superiority in experienced gamers compared to those who avoid them, says Sijing Wu, a PhD candidate in Spence鈥檚 lab in U of T鈥檚 Department of Psychology and lead author of the study. 鈥淎 training experiment was necessary to establish whether playing an action game could actually improve search skills.鈥
In the second experiment, 60 participants 鈥 who had not previously played videogames 鈥 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.
鈥淎fter playing either the shooter or driving game for only 10 hours, participants were faster and more accurate on the three visual search tasks,鈥 says Wu. 鈥淗owever, the control participants 鈥 who played the puzzle game 鈥 did not improve.鈥
鈥淲e have shown that playing a driving-racing game can produce the same benefits as a shooter game,鈥 says Wu. 鈥淭his 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.鈥
The study is available online in the journal Attention, Perception, & Psychophysics. The research was supported by funding from the Natural Sciences and Engineering Research Council of Canada in the form of a Discovery Grant to Spence.
