In August, British researchers found that certain video games, particularly strategic games such as "Starcraft," can increase a player's "brain flexibility,"which the scientists described as "a cornerstone of human intelligence."
The study, conducted at Queen Mary University of London and University College London, is based on psychological tests conducted before and after 72 volunteers played "Starcraft" or the life-simulation game "The Sims" for 40 hours over six to eight weeks. They found that participants assigned to play "Starcraft" experienced gains in their performance on psychological tests, completing cognitive flexibility tasks with greater speed and accuracy.
"We need to understand now what exactly about these games is leading to these changes, and whether these cognitive boosts are permanent or if they dwindle over time," study researcher Brian Glass said in August. "Once we have that understanding, it could become possible to develop clinical interventions for symptoms related to attention deficit hyperactivity disorder or traumatic brain injuries, for example."
