Affordance evocation has been shown to be sensitive to several contextual factors. Affordances are mainly activated when objects are perceived within reach (Wamain et al. 2016), an effect enhanced in presence of a congruent verbal context (Costantini et al. 2011). Moreover, recent findings demonstrated a processing cost for objects associated with conflicting affordances, namely objects evoking distinct grasp-to-use and grasp to-move gestures (“conflictual” objects). When asked to make perceptual judgements on 3D objects presented at different distances, participants were slower for “conflictual” than “non-conflictual” objects, but only when objects were presented within reach (Kalénine et al. 2016). At the neurophysiological level, this selective cost for conflictual objects was reflected by a reduction of µ rhythm desynchronization, suggesting that competition between object affordances alters motor resonance during manipulable object perception (Wamain et al. 2018). The present study aims at evaluating the effect of a verbal context on affordance competition. Using EEG, we tested whether a congruent action verb could help the resolution of the competition between object affordances and induce a release of µ rhythm desynchronization during object perception. Twenty-five participants had to make perceptual judgements on 3D conflictual objects (e.g., calculator, affording both clench and poke) presented at different distances in a virtual environment while EEG was recorded. Objects were preceded by an action verb congruent with their grasp-to-use action (compute) or a neutral verb (observe). Results demonstrate that the competition elicited by the perception of distinct affordances during object processing is sensitive to verbal context. Critically, µ rhythm desynchronization increased in the presence of an action verbal context describing the typical use gestures associated with conflictual objects. These findings provide novel insights into the influence of contextual information on the resolution of the competition between object affordances that may help enriching recent theoretical views on affordances.Show less >
