The main objective of this project is to study whether intranasal oxytocin (OT) affects how
young adults perceive and attend to infant and adult faces. Based on existing research the
investigators predict that oxytocin will facilitate the allocation of attentional resources
on infant faces (compared to adult faces). The investigators also predict that oxytocin will
enhance the activity of reward neural-networks associated with the perception of infant
faces. The behavioral effects of OT (visual attention and face recognition) will be measured
with eye-tracking while participants look at photographs of adult and infant faces.
Neurological effects (the activity of emotion and reward networks) will be measured with
functional Magnetic Resonance Imaging (fMRI) while participants look at infant faces on a
computer screen.
