Left-handers aren't better spatially, gaming research shows

By asking participants to download and play a video game that captured user information and tracked navigational challenges, researchers were able to measure demographic data -- including hand preference -- and activity from more than 420,000 international participants, across 41 different countries. They found that left-handers were neither better nor worse than right-handers at the tasks, clarifying a long-running debate about the links between handedness and spatial skills.
