Oxytocin is a naturally occurring brain chemical that is nicknamed the “love hormone” because it seems to play a role in the formation of social relationships such
as mating pairs and parent-child bonding. A recent study demonstrated that oxytocin appears to increase people’s tendency to trust others (Kosfeld, Heinrichs,
Zak, Fischbacher, and Fehr, 2005). Using an investment game, the study demonstrated that people who inhaled oxytocin were more likely to give their money to a trustee compared to people who inhaled an inactive placebo. For this experimental study, identify the independent variable and the dependent variable.
