Scenario II
Scenario II presents fabricated data inspired by the following study:
Scheele, D., Striepens, N., Gunturken, O., et al. (2012) . Oxytocin modulates social distance between males and females. The Journal of Neuroscience, 32(46) , 16074-16079.
Oxytocin and Attraction Study
The purpose of this study was to examine whether oxytocin (OXT) affects the way in which single men and committed men respond to an unfamiliar woman. To that end, men received either OXT or a placebo via intranasal administration after which they were introduced to a woman. The researchers measured the distance men kept from the woman and hypothesized that shorter distances indicated interest in her. The results showed that the distance between the men and women differed based on the treatment men received. Specifically, committed men who received OXT kept a significantly greater distance from the woman compared with not only committed men who received the placebo, but also single men who received either the placebo or OXT. This study suggests that OXT may contribute to monogamy in males.
-(Scenario II) The researcher who administered the intranasal spray to participants in Scenario II did not know whether the spray contained OXT. This procedure was probably implemented in order to enhance:
