Paranoia is the exaggerated belief that harm will occur and is intended by others. Although commonly framed in terms of attributing malicious intent to others, recent work has explored how paranoia also affects social decision-making, using economic games. Previous work found that paranoia is associated with decreased cooperation and increased punishment in the Dictator Game (where cooperating and punishing involve paying a cost to respectively increase or decrease a partner's income). These findings suggest that paranoia might be associated with variation in subjective reward from positive and/or negative social decision-making, a possibility we explore using a preregistered experiment with U.S.-based participants (n = 2,004). Paranoia was associated with increased self-reported enjoyment of negative social interactions and decreased self-reported enjoyment of prosocial interactions. More paranoid participants attributed stronger harmful intent to a partner. Harmful intent attributions and the enjoyment of negative social interactions positively predicted the tendency to pay to punish the partner. Cooperation was positively associated with the tendency to enjoy prosocial interactions and increased with participant age. There was no main effect of paranoia on tendency to cooperate in this setting. We discuss these findings in light of previous research. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

偏执狂中的社会奖励，惩罚和亲社会。

偏执狂是一种夸大的观念，认为伤害会发生，并且是他人故意造成的。尽管通常以将恶意意图归因于他人为框架，但最近的工作已经探索了偏执狂如何使用经济游戏来影响社会决策。先前的工作发现，妄想症与独裁者博弈中的合作减少和惩罚增加相关（合作和惩罚涉及支付费用以分别增加或减少伴侣的收入）。这些发现表明，妄想症可能与积极和/或消极的社会决策中主观奖励的变化有关，这是我们使用预先注册的针对美国参与者的实验进行探讨的可能性（n = 2,004）。妄想症与自我报告的消极社交互动的乐趣增加和自我报告的亲社交互动的乐趣减少有关。更多的偏执狂参与者将更强烈的有害意图归因于伴侣。有害的意图归因和消极的社会互动的享受积极地预示了为惩罚伴侣而付出的趋势。合作与享受亲社会互动的倾向呈正相关，并随着参与者年龄的增加而增加。在这种情况下，偏执狂对合作倾向没有主要影响。我们根据先前的研究讨论这些发现。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。有害的意图归因和消极的社会互动的享受积极地预示了为惩罚伴侣而付出的趋势。合作与享受亲社会互动的倾向呈正相关，并随着参与者年龄的增加而增加。在这种情况下，偏执狂对合作倾向没有主要影响。我们根据先前的研究讨论这些发现。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。有害的意图归因和消极的社会互动的享受积极地预示了为惩罚伴侣而付出的趋势。合作与享受亲社会互动的倾向呈正相关，并随着参与者年龄的增加而增加。在这种情况下，偏执狂对合作倾向没有主要影响。我们根据先前的研究讨论这些发现。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。
