Figure 1. Visualisation of the influence of testosterone on bluffing behavior relative to the equilibrium strategy.

Testosterone specifically reduces bluffing with weak hands, i.e. ‘cold bluffing’. Polynomial fits are based on the proportion of high bets with increment-size 0.01 over the full range of poker hands (0–1).
Figure 2. Proportion of calls with logistic regression lines for placebo and testosterone representing their main effect in the multiple logistic regression model.

Testosterone increases calling.
