title: Embodied preference judgments: can likeability be driven by the motor system?
abstract: Can covert sensorimotor simulation of stimulus-relevant actions influence affective judgments, even when there is no intention to act? Skilled and novice typists picked which of two letter dyads they preferred. In each pair, one dyad, if typed using standard typing methods, would involve the same fingers (e.g., FV); the other would be typed with different fingers (e.g., FJ). Thus, if typed, dyads of the former kind should create more motor interference than dyads of the latter kind. Although individuals could not explain how the dyads differed, skilled typists preferred those typed with different fingers. Novices showed no preference. Moreover, a motor task performed while making dyad preference judgments attenuated skilled typists' preference--but only when the motor task involved the specific fingers that would be used to type the dyads. These findings suggest that in skilled typists, perceiving letters prompts covert sensorimotor simulation of typing them, which in turn influences affective judgments about this information.
