Expertise and its embodiment: examining the impact of sensorimotor skill expertise on the representation of action-related text.

In two experiments, we explored how novice and expert athletes represent the everyday and sport-specific objects and actions that they read about. Novice and expert ice hockey players (Experiment 1) and football players (Experiment 2) read sentences describing everyday or sport-specific situations and then judged whether a pictured item (either matching the action implied in the previous sentence or not) was mentioned in the preceding sentence. The sentences in Experiment 1 consisted of everyday and hockey-specific scenarios. The sentences in Experiment 2 depicted football scenarios implying football-specific or non-football-specific actions anyone might perform. Everyone responded most quickly to items that matched the sentence-implied actions for everyday and non-sport-specific actions. Only athletes showed this effect for their respective sport-specific scenarios. Differentiating between the same item in different action orientations is thought to be driven by embodied knowledge containing the sensorimotor characteristics of what one is reading about. We show that possessing this type of representation depends on experience interacting with objects and performing the actions in question.
