The present study tested whether observing the outcome of others' actions altered the observer's PPS representation and exploitation. Participants (observers) performed a reachability-judgement task (assessing PPS representation) before and after having observed a confederate (actors) performing a stimuli-selection task on a touch-screen table. In the stimuli-selection task, the stimuli selected could either yield a reward or not, but the probability to select a reward-yielding stimulus was biased in space, being either 50%, 25% or 75% in the actor’s proximal or distal space. After the observation phase, participants performed the stimuli-selection task (assessing PPS exploitation), but with no spatial bias in the distribution of reward-yielding stimuli. Results revealed an effect of actors’ actions outcome on observers’ PPS representation, which changed according to the distribution of reward-yielding stimuli in the actors’ proximal and distal spaces. No significant effect of actors’ actions outcome was found on observers’ PPS exploitation. As a whole, the results suggest dissociated effects of observing the outcome of others’ actions on PPS representation and exploitation.Lire moins >
