The Effect of Intranasal Administration of Oxytocin on Empathic Abilities.

Empathy constitutes one prominent ability of social cognition, which represents the human capability of understanding mental state of the other, and responding in sympathetic way. Two sets of theoretical mechanisms were designed in order to explain how empathy is possible. Theory of Mind (ToM)and Simulation.People who suffer from schizophrenia frequently exhibit social dysfunction, preventing them of a normal integration in healthy human environments. Recently it had been discovered that impairment in empathy and a specific impairment in effective TOM are mostly associated with the social malfunctioning of people who suffer from schizophrenia. One of the biological substances most connected to social cognition is the neuromodulator Oxytocin. Among its known involvement in uterine contractions and lactating females, numerous recent studies have found an indispensable role for Oxytocin in various complex prosocial behaviors such as maternal behavior, attachment, partner preference and trust. In the proposed study, we plan to examine the influence of a single dose of intranasal Oxytocin on the two primary mechanisms of empathy, namely mentalizing (Theory of Mind) and Simulation, both in healthy people and in people who suffer from schizophrenia.
