Association between objects and body parts mediated by function

Recent accounts of conceptual knowledge suggest that the specific gestures/actions that should be performed in order to use an object for its intended function are an integral part of its mental representation. If this is true, then the information regarding which body part needs activating to interact with the object should also be part of such representation. Starting from the assumption that not only artefacts (i.e., tools), but also natural objects (i.e., fruits and vegetables) have a function, the present study investigates the existence of a link between a specific object and the effector involved in its use. The Implicit Association Test (IAT) paradigm was adopted to test for an association between natural objects and mouth, and between artefacts and hand (Experiment 1) or foot (Experiment 2). Results showed selective links between objects and effectors, based on which body part is needed to carry out the object's function.
