Recent findings indicate that the mental representation of an object contains crucial information about the motor interactions relevant for its intended functional use, suggesting a possible action-specific link with body effectors. For example, in the visual system, the extrastriate body area (EBA) responds to full body and body part images according to a functional/semantic organizational principle. However, the pliancy of the relationship between objects and body parts remains under-investigated. The present study aims to i) investigate this relationship more directly by assessing whether recognition of specific body parts can be facilitated by a brief exposure to functionally-related objects (Experiment 1) and ii) whether the functional relationship between objects and body parts modulates a posterior body-sensitive ERP waveform, peaking around 200 ms, and the more centro-parietal P300, linked to item categorization processes and visual awareness (Experiment 2). Participants were asked to quickly recognize targets (pictures of hands or feet) preceded by a functionally related (e.g., drum for hand target), unrelated (e.g., drum for foot target), or neutral (e.g., unknown object for both targets) prime. Findings showed that participants’ performance was significantly more accurate with related than unrelated primes and that ERP amplitudes were modulated by the relationship between the prime and the target. These findings confirm the existence of action-specific links between objects and body parts and expand on recent findings on categorical organization of neural responses to human effectors in the visual system.

... Motor imagery is known to impose a negativity over the P300 component (Hilton et al., 2022;Yan et al., 2012) and may explain the reduced P300 potentials observed in our study for the activity conditions compared to the no-activity condition. In a study by Caggiano et al. (2022), participants categorised body parts and they found that P300 amplitudes were reduced when participants were primed with objects that afforded use by the shown body part (e.g. a drum for hands). They suggested that information about which body part might be needed to interact with the external world is extracted during perception according to their relevance for action-affordance relationships. ...
