Note: Results of fixed-effects regressions of HRV during the betting decision and own score in the first round on the amount of correct answers by the assigned player. The average HRV across all participants for the corresponding decisions was 2.37. Specifications BET1-3 use alternative measures of HRV . BET1 uses the direct measure at the moment of decision making, BET2 and BET3 normalize this value by the average individual during the experiment and the round, respectively. Standard errors (clustered by individuals) are in brackets. **p < 0.01, *p < 0.05, ^†p < 0.1.
