问题赌博是一个严重的社会经济问题，涉及高个人和社会成本。在本文中，我们研究了问题赌徒的风险偏好，包括他们在收益和损失领域的风险态度，他们的概率加权和他们的损失厌恶程度。我们的研究结果表明，问题赌徒在系统上更愿意冒险，而且只对收益域的概率变化不太敏感。他们在损失领域的风险态度和损失厌恶程度都与对照组没有显著差异。在电击威胁任务中，皮肤电导数据（一种情绪唤醒的心理生理标记）获得了对负面结果具有相似程度敏感性的额外证据。
Problem gambling is a serious socioeconomic problem involving high individual and social costs. In this article, we study risk preferences of problem gamblers including their risk attitudes in the gain and loss domains, their weighting of probabilities, and their degree of loss aversion. Our findings indicate that problem gamblers are systematically more risk taking and less sensitive toward changes in probabilities in the gain domain only. Neither their risk attitudes in the loss domain nor their degree of loss aversion are significantly different from the controls. Additional evidence for a similar degree of sensitivity toward negative outcomes is gained from skin conductance data—a psychophysiological marker for emotional arousal—in a threat-of-shock task.
