Abstract	Mental stimulation of motor actions was examined in 94 healthy young subjects. The duration of imagined and executed writing tasks using dominant and non-dominant hands were compared. An imagination/execution time ratio was calculated to examine the temporal congruence of the two conditions. The duration of the executed and imagined writing tasks was greater when using the non-dominant hand than when using the dominant hand. The duration of the writing task with the dominant hand was greater in the imagined condition than in the executed condition, which suggests a lack of temporal congruence in the imagined condition. These results indicate that the motor simulation time was affected by the difference between task difficulty and the brain activation areas.
Keywords	motor imagery, mental chronometry, temporal congruence, task difficulty
