The present study comprises a series of four experiments that investigate the effects of voluntary attention on distinct representations of body parts. On the one hand, our research follows up the classical study of attentional processes, as one of its aims is to clarify whether humans are able to orient themselves to particular exemplars of a same perceptual category. On the other hand, it provides a revolutionary way to research self and other’s body representations, investigating how the previous activation of these two different schemes could influence the visual perception of self and other-related stimuli. In order to achieve our goals, we used an adaptation of the Cost and Benefits attentional Paradigm (Posner, 1980) where a coloured cue predicted (80% probability) the nature of the hand target (own vs. other), leading to valid (expected) and invalid (not expected) trials. Participants had to judge whether the presented forelimb was a left or a right hand independently of its identity. Our main hypothesis proposed that the subjects would be able to orient themselves either to Own or Other’s representation. However, we also suggested a differential development of these two attentional effects. Experiment 1 revealed a significant Status (Own vs Other hand) x Validity (Valid vs Invalid) interaction, showing an orienting effect exclusively present in self-related stimuli. Experiment 2 explored an alternative explanation of these results in terms of own-hand motor activation, in contrast to a more traditional interpretation as a facilitation of visual processing. The results of this second experiment replicated those of Experiment 1. In the first two experiments, participants performed a recognition task prior to the proper experiment in which they only responded to their own hand. Experiment 3 revealed that Other’s hand representation is also susceptible to be developed, manipulating implicitly the perceived value of the target. The target value was modified by means of asking participants to respond to both stimuli (Own and Other hand) in the recognition block of trials. In light of results, Experiment 4 investigates whether the attentional orientation effect to our own and Other’s body parts relies on different processes. In conclusion, the results of this set of experiments provides promising initial data in the research addressing the attentional modulation of the representations of our own and other’s body, offering a new perspective to explore Self and Others distinction.
