背景技术背景：众所周知，患有精神分裂症的个体具有多巴胺能异常以及与记忆相关的困难，这两者都与冲动决策有关。我们使用了延迟折扣措施，以测试患者作出面向未来的decisions.METHODS的程度：42例精神分裂症患者和29名健康参与者完成了延迟折扣措施沿着与测试的认知功能，并在患者中，症状ratings.RESULTS：患者折扣更陡比比较参与者。折扣患者之间的记忆能力和负向symptoms.CONCLUSIONS：冲动的决策证明了患者表明，他们可能倾向于选择即时的长期奖励，即使他们的利益是更好地服务于选择后者。改善认知功能可以提高他们做出面向未来的决定的能力。
BACKGROUND: It is well known that individuals with schizophrenia have dopaminergic abnormalities as well as memory-related difficulties, both of which are associated with impulsive decision making. We used a delay discounting measure to test the degree to which patients make future-oriented decisions.METHODS: 42 patients with schizophrenia and 29 healthy participants completed a delay discounting measure along with tests of cognitive function and, in patients, symptom ratings.RESULTS: Patients discounted more steeply than did comparison participants. Discounting among patients related to memory capacity and tended to relate inversely to negative symptoms.CONCLUSIONS: The impulsive decision making evidenced by patients suggests that they may be prone to choosing immediate over long-term rewards, even when their interests are better served by choosing the latter. Improving cognitive function may enhance their ability to make future-oriented decisions.
