The role of motor processes in three-dimensional mental rotation: Shaping cognitive processing via sensorimotor experience

An extensive body of literature has explored the involvement of motor processes in mental rotation, yet underlying individual differences are less documented and remain to be fully understood. We propose that sensorimotor experience shapes spatial abilities such as assessed in mental rotation tasks. Elite wrestlers' and non-athletes' mental rotation accuracy and response times were measured in three different conditions: mental rotation (a), mental rotation with visual (b) and movement (c) interference. Results showed that both groups were equally affected by the visual interference task, as hypothesized from previous literature. However, the movement interference task impacted tremendously more wrestlers' mental rotation performance. These findings suggest that experts in motor activities rely heavily on motor processes in three-dimensional mental rotation problems solving, thus performing more poorly when simultaneously holding movements. The implications of this work in providing further evidence for the close tie between perceptive, motor and cognitive processes are discussed.

► We propose that sensorimotor experience influences mental rotation ability.
► We assessed mental rotation ability in athletes and non-athletes in three conditions.
► Athletes showed significantly better mental rotation performance.
► A movement interference task affected elite athletes more than non-athletes.
► Experts rely heavily on motor processes in mental rotation problems solving.
