Can we learn something from playing video games? New research by Adam Chie-Ming Oei and Michael Donald Patterson of Nanyang Technological University, Singapore, does suggest this is the case. Playing video games for an hour each day can improve subsequent performance on cognitive tasks that use similar mental processes to those involved in the game

From the press release:

Non-gamer participants played five different games on their smartphones for an hour a day, five days of the week for one month. Each participant was assigned one game. Some played games like Bejeweled where participants matched three identical objects or an agent-based virtual life simulation like The Sims, while others played action games or had to find hidden objects, as in Hidden Expedition.

After this month of ‘training’, the researchers found that people who had played the action game had improved their capacity to track multiple objects in a short span of time, while hidden object, match three objects and spatial memory game players improved their performance on visual search tasks. Though previous studies have reported that action games can improve cognitive skills, the authors state that this is the first study that compared multiple video games in a single study and show that different skills can be improved by playing different games. They add that video games don’t appear to cause a general improvement in mental abilities. Rather like muscles that can be trained with repetitive actions, repeated use of certain cognitive processes in video games can improve performance on other tasks as well.

Abstract of the research that can be read online here:

Background: Previous evidence points to a causal link between playing action video games and enhanced cognition and perception. However, benefits of playing other video games are under-investigated. We examined whether playing non-action games also improves cognition. Hence, we compared transfer effects of an action and other non-action types that required different cognitive demands.

Methodology/Principal Findings: We instructed 5 groups of non-gamer participants to play one game each on a mobile device (iPhone/iPod Touch) for one hour a day/five days a week over four weeks (20 hours). Games included action, spatial memory, match-3, hidden- object, and an agent-based life simulation. Participants performed four behavioral tasks before and after video game training to assess for transfer effects. Tasks included an attentional blink task, a spatial memory and visual search dual task, a visual filter memory task to assess for multiple object tracking and cognitive control, as well as a complex verbal span task. Action game playing eliminated attentional blink and improved cognitive control and multiple-object tracking. Match-3, spatial memory and hidden object games improved visual search performance while the latter two also improved spatial working memory. Complex verbal span improved after match-3 and action game training.

Conclusion/Significance: Cognitive improvements were not limited to action game training alone and different games enhanced different aspects of cognition. We conclude that training specific cognitive abilities frequently in a video game improves performance in tasks that share common underlying demands. Overall, these results suggest that many video game-related cognitive improvements may not be due to training of general broad cognitive systems such as executive attentional control, but instead due to frequent utilization of specific cognitive processes during game play. Thus, many video game training related improvements to cognition may be attributed to near-transfer effects.
