Quality of decision making	98±0.5	95±0.8	z = 2.44, p = 0.01*
Deliberation time (ms)	1934±541	2413±905	z = −3.34, p = 0.005*
Betting behavior

Risk adjustment	1.6±0.7	1.4±0.9	z = −1.1, p = 0.28

Msec = milliseconds. Values are means ± standard deviation (SD). P-values reflect non parametric comparisons.

^*reflects significant difference. After correction for type 1 error, alpha was set at.025 for choice behavior (2 Items) and for betting behavior (idem).
