Official Title: The Behavioral and Neural Effects of Oxytocin on Face Perception in Congenital Prosopagnosia

Brief Summary: The purpose of this study is to determine whether oxytocin affect face perception

Detailed Summary:
Sponsor: Soroka University Medical Center

Current Primary Outcome: Memory performance [ Time Frame: Day 2 (24 hours after encoding) ]

At the day participants will administer the substance, they will view a set of faces, of which they will be tested about 24 hours later. The measures that will be tested are %accuracy and %dwell time of eye movements towards each region in the faces the participants saw.


Original Primary Outcome: Memory performance [ Time Frame: 24 hours after encoding ]

At the day participants will administer the substance, they will view a set of faces, of which they will be tested about 24 hours later. The measures that will be tested are accuracy and eye movements.


Current Secondary Outcome: Mood measurement [ Time Frame: Day 1 (after oxytocin/placebo uptake) ]

Participants will fill a PANAS mood questionnaire in order to monitor the effects of mood and fatigue of oxytocin/placebo. We will use ANOVA on the total score of the test in order to verify that differences in performance are not due to change in mood or fatigue after substance uptake.


Original Secondary Outcome: Mood measurement [ Time Frame: Before oxytocin/placebo uptake, and 45 min. after ]

Participants will fill a PANAS mood questionnaire just before oxytocin/placebo uptake, and 45 minutes after oxytocin/placebo uptake, in order to monitor the effects of mood and fatigue of oxytocin/placebo.
