  • Title: Valence-space compatibility effects depend on situated motor fluency in both right- and left-handers.

    Abstract:
    According to the body specificity hypothesis, the way we interact with our environment participates in our conceptualization of concepts and word meanings. For instance, valence is associated to horizontal space because of the motor fluency by which one acts with one's dominant hand. We propose that the decisive factor in the compatibility effects between valence and lateral actions is the interaction between the fluency of response movement and the situational constraints of the task. In a valence judgement task with positive and negative words, right-handers (Experiment 1) and left-handers (Experiment 2) responded with lateralized actions of either their dominant or their nondominant hand. To do so, we used a response device that was either congruent or noncongruent with the fluency of the response hand. Results highlighted that when the response device was congruent with the fluency of the responding hand, response times to positive evaluations were shorter than those to negative evaluations. Conversely, when the response device was noncongruent with the fluency of the responding hand, we observed faster responses for negative evaluations than for positive evaluations. Furthermore, we obtained similar patterns for right- and left-handers, supporting the idea that compatibility effects are driven by the situated fluency of the responding hand.
