Summary
Progesterone plays a role in human bonding behavior. We investigate how salivary PROG is related to bond-centered moral reasoning. We find that higher PROG is associated with an increased use of bond-centered moral justifications.
Background & Theory
Progesterone: • A steroid hormone present in both males and females • PROG increases after randomly assigned close social interactions (Brown et al., 2009) • There is a positive correlation between PROG and the need for affiliation (Schultheiss, Dargel, & Rhode, 2003; Wirth & Schultheiss, 2006)
Moral reasoning • Involves analyzing moral dilemmas with no obvious right or wrong course of action • Moral reasoning increases during childhood but is stable in adulthood (Armon 1998) • Moral reasoning scores linked with higher prosocial behaviors and lower aggression and delinquency (Arbuthnot et al, 1986; Bredemeier, 1994 ; Eisenberg et al., 1989) Research question • Is there a possible relationship between bond-centered moral reasoning and baseline salivary PROG?
Methods Progesterone • Two salivary PROG levels were averaged (α=0.88) to create a basal PROG score • Saliva samples were analyzed via enzyme immunoassay
Classic Moral Dilemma Participants were asked whether a man (Heinz) should steal a drug to save his wife or abide by the law, accepting his unfortunate circumstance (Colby & Kohlberg, 1987)
Participants were asked 5 questions about the dilemma, and the questions were coded by research assistants blind to participants’ progesterone levels. 1) Should Heinz steal the drug? Why or why not? 2) Is it right or wrong for him to steal the drug? Why is it right or wrong? 3) Suppose the person dying is not his wife but a stranger. Should Heinz steal the drug for the stranger? Why or why not? 4) It is against the law for Heinz to steal. Does that make it morally wrong? Why or why not? 5) In thinking back over the dilemma, what would you say is the most responsible thing for Heinz to do? Why?
Results
Descriptive Statistics
Two Types of Coding:
1) Kohlberg’s stages of moral reasoning 2) Bond-centered moral reasoning
Discussion
Interpretations & Implications • An increased use of bond-centered moral
justifications was associated with higher basal PROG levels
• Kohlberg’s moral stages were unrelated to PROG levels
• These effects especially apply to females, and exist even when controlling for word count
• The results may imply that moral reasoning may not be a stable trait, but may vary with changes in hormone levels
Limitations & Future Directions • Study is limited by relatively small and
homogenous sample • In addition, we did not collect information on
hormonal birth control usage or timing of menstrual cycle
• Finally, the correlational nature of the design makes it impossible to determine the direction of causality or the role of third variables
• Future studies should be conducted to determine causal direction
• Other future studies could examine whether moral reasoning changes with predictable hormonal changes (e.g. menstrual cycle)
