Abstract

Variation in reward responsiveness has been linked to psychopathology. Reward responsiveness is a complex phenomenon that encompasses different temporal dimensions (i.e., reward anticipation or consumption) that can be measured using multiple appetitive stimuli. Furthermore, distinct measures, such as neural and self-report measures, reflect related but distinct aspects of reward responsiveness. To understand reward responsiveness more comprehensively and better identify deficits in reward responsiveness implicated in psychopathology, we examined ways multiple measures of reward responsiveness jointly contribute to distinct psychological problems by using latent profile analysis. Specifically, we identified three profiles of reward responsiveness among 139 female participants based on their neural responses to money, food, social acceptance, and erotic images and self-reported responsiveness to reward anticipation and consumption. Profile 1 (n = 30) exhibited blunted neural responses to social rewards and erotic images, low self-reported reward responsiveness, but average neural responses to monetary and food rewards. Profile 2 (n = 71) showed elevated neural response to monetary rewards, average neural responses to other stimuli, and average self-reported reward responsiveness. Profile 3 (n = 38) showed more variable neural responses to reward (e.g., hypersensitivity to erotic images, hyposensitivity to monetary rewards), and high self-reported reward responsiveness. These profiles were differentially associated with variables generally linked to aberrations in reward responsiveness. For example, Profile 1 was most strongly associated with anhedonic depression and social dysfunction, whereas Profile 3 was associated with risk-taking behaviors. These preliminary findings may help to elucidate ways different measures of reward responsiveness manifest within and across individuals and identify specific vulnerabilities for distinct psychological problems.

摘要

奖赏反应性的变化与精神病理学有关。奖赏反应性是一种复杂的现象,包含不同的时间维度(即奖励预期或消费),可以使用多种奖赏刺激来测量。此外,不同的测量方法,如神经和自我报告测量方法,反映了奖赏反应性的相关但不同的方面。为了更全面地理解奖赏反应性,并更好地识别与精神病理学有关的奖赏反应性缺陷,我们使用潜在剖面分析来研究多种奖赏反应性测量方法如何共同导致不同的心理问题。具体来说,我们根据 139 名女性参与者对金钱、食物、社会接纳和色情图像的神经反应以及对奖励预期和消费的自我报告反应,确定了奖赏反应性的三种模式。模式 1(n=30)表现为对社会奖励和色情图像的神经反应迟钝,自我报告的奖励反应性低,但对金钱和食物奖励的神经反应平均。模式 2(n=71)表现为对金钱奖励的神经反应升高,对其他刺激的神经反应平均,以及对奖励预期和消费的平均自我报告反应性。模式 3(n=38)表现出对奖励的神经反应更具可变性(例如,对色情图像的超敏反应,对金钱奖励的低敏反应),以及高自我报告的奖励反应性。这些模式与一般与奖赏反应性异常相关的变量有不同的关联。例如,模式 1与快感缺失性抑郁和社会功能障碍最密切相关,而模式 3与冒险行为有关。这些初步发现可能有助于阐明不同的奖赏反应性测量方法在个体内部和跨个体之间的表现方式,并确定特定的心理问题的特定脆弱性。
