Brief Summary:
In this study, the influence of oxytocin on automatic imitation behaviour is investigated. Healthy adults will be administered with either oxytocin or a placebo, and will perform an imitation-inhibition task (as a measure of automatic imitation behaviour). To determine the specificity of the oxytocin effect, an unrelated cognitive task (Stroop task) will also be presented.

Arm Intervention/treatment
Experimental: Oxytocin
Oxytocin 24 IU (3 puffs) per nostril
Drug: Oxytocin
Placebo Comparator: Sea water
Sea water 3 puffs per nostril
Drug: Sea water

Primary Outcome Measures :
  1. To evaluate the automatic imitation behaviour 45 minutes after drug administration [ Time Frame: 120 minutes ]
    Since the effects of oxytocin are only visible after 45 minutes, participants will have to wait 45 minutes before starting the experimental tasks. In the meantime, they will be given an unrelated cognitive-emotional filler task which will last ± 30 minutes. Afterwards, they will perform two experimental tasks: an imitation-inhibition task and a cognitive control task (Stroop task).
