The right ones seem to be able to. Successful players of games requiring strategy, creativity, and teamwork, research finds, tend to have a higher IQ than others. A similar connection between IQ and gaming success was not found in studies of first-person shooter-type games that rely on hand-eye coordination. But other studies find that playing certain games can actually help boost IQ. Studies that involved popular puzzle-based strategy games, particularly those involving complex, changing environments, led to gains in problem solving, spatial skills, and persistence. Significantly, such results were not found in studies of so-called “brain-training” games marketed as cognitive boosters.
