PolyU research reveals neurocognitive correlates of testosterone in young men that shape generosity and self-worth (IMAGE)
Caption
Testosterone increases social discounting. (A) Generosity, as measured by the amount of money participants were willing to forgo to benefit the other person, decreased with social distance, both under placebo and testosterone. Amounts forgone were obtained separately for each participant by fitting a logistic function to the choices at each social distance. The mean amounts forgone were then fitted with a hyperbolic function capturing social discounting. (B) The discount rates (k, i.e., steepness of the individually determined social discounting function) were larger for the testosterone group than for the placebo group (Mann–Whitney U test = 386, Z = 2.33, and P = 0.020). All error bars are SEMs.
