This study reports experimental results from a clinical sample of patients with a cocaine-related disorder and dual diagnosis: Schizophrenia and Anti-Social Personality Disorder. Both types of patients as well as a non-clinical group of students performed two incentivized decision-making tasks. In the first part of the experiment, they performed a lottery-choice task in order to elicit their degree of risk aversion. In the second part, they decided in two modified dictator games aimed at eliciting their aversion to advantageous and disadvantageous inequality. It is found that the Anti-Social Personality Disorder group exhibits no significant differences from the non-clinical sample in either task. However, compared with the students' sample, subjects from the group with schizophrenia show more risk aversion and exhibit more aversion towards disadvantageous inequality.
本研究报告了一项针对可卡因相关障碍和双重诊断（精神分裂症和反社会人格障碍）患者的临床样本的实验结果。两种类型的患者以及一组非临床的学生群体完成了两项激励决策任务。在实验的第一部分，他们完成了一项彩票选择任务，以引出他们的风险厌恶程度。在第二部分，他们在两个经过修改的独裁者游戏中做出决策，旨在引出他们对有利和不利不平等的厌恶。结果发现，反社会人格障碍组在两个任务中与非临床样本均无显著差异。然而，与学生样本相比，精神分裂症组的受试者表现出更高的风险厌恶程度，并对不利的不平等表现出更强的厌恶。
