Quizplus · Accepted Answer

Ideo-motor theory suggests that the mental representation of an action can activate the motor system necessary to perform that action, even without conscious intention. Therefore, the reaction time for a motor response to a heard word should be shorter than for a written response, as the association between language and the corresponding motor movements is stronger for speech than writing.
