Polysubstance dependent patients display a more utilitarian profile in moral decision-making than alcohol-dependent patients, depressive patients and controls

The absence of correlation between performance on the Iowa Gambling Task and the number of more utilitarian choices indicates that moral dilemma and decision making under uncertainty tap into separate mechanisms.
