| Outline of Final Research Achievements |
Endogenous testosterone (T) is generally considered to enhance social dominance, but the results of economic game experiments that have examined the relationship between decision making and T are inconsistent. We explored the relationship between pre-existing social status and salivary T level among members of a rugby team at a Japanese university, where a strong seniority norm maintains hierarchical relationships. We analyzed participants’ level of acquiescence (how much more they offered beyond the lowest offer they would accept) based on their decisions both as proposer and responder in a series of one-shot Ultimatum Games. In summary, our results consistently suggest that T may enhance socially dominant behavior among higher-status persons, and that the effect of T on lower-status persons merits further investigation.
