【摘要】人类经常从事内在有益的活动（例如，消费艺术品、阅读）。尽管这些活动看起来多种多样，但我们表明对内在奖励的敏感性是普遍的，并且与心理健康相关。在这项横断面研究中，在线参与者（N = 483）获得了假定的视觉、认知和社会内在奖励以及金钱奖励和中性刺激。所有奖励都会引发积极的感觉（被“喜欢”），产生完美的行为（被“想要”），并增加导致这些行为的可能性（被“强化”）。因子分析显示，大约40%的刺激反应差异可以用对所有奖励的普遍敏感性来解释，但对中性刺激则不然。心理健康的情感方面与对内在奖励的敏感性有关，但与金钱奖励无关。这些结果可能有助于解释兴旺发达和痛苦：奖励敏感性高的个体会从事各种本质上有益的活动，最终找到他们擅长的活动，而敏感性低的个体则不会。

[Abstract] Humans frequently engage in intrinsically rewarding activities (for example, consuming art, reading). Despite such activities seeming diverse, we show that sensitivity to intrinsic rewards is domain general and associated with mental health. In this cross-sectional study, participants online (N = 483) were presented with putative visual, cognitive and social intrinsic rewards as well as monetary rewards and neutral stimuli. All rewards elicited positive feelings (were ‘liked’), generated consummatory behaviour (were ‘wanted’) and increased the likelihood of the action leading to them (were ‘reinforcing’). Factor analysis revealed that ~40% of response variance across stimuli was explained by a general sensitivity to all rewards, but not to neutral stimuli. Affective aspects of mental health were associated with sensitivity to intrinsic, but not monetary, rewards. These results may help explain thriving and suffering: individuals with high reward sensitivity will engage in a variety of intrinsically rewarding activities, eventually finding those they excel at, whereas low sensitivity individuals will not.
