Abstract

Preliminary evidence suggests that mental imagery-based elaboration of rewarding activities enhances anticipated pleasure, motivation, and behavioral engagement in non-clinical samples, but its effects in individuals experiencing anhedonia (loss of pleasure/interest) is unclear. Study 1 (N = 90) contrasted imagery-enhanced activity scheduling with two scheduling-only control conditions (Reminder/No Reminder Control) in an unselected sample. Study 2 (N = 108) compared imagery-enhanced activity scheduling with two control conditions (Neutral Imagery/Motivational Verbal Reasoning) in individuals experiencing mild to moderate anhedonia. Both studies measured changes in activity appraisal (anticipated pleasure, anticipated reward/mastery, motivation) in the lab, and behavioral engagement across a subsequent 7-day period. Additionally, Study 2 assessed heart rate as a psychophysiological marker of emotional response across conditions. Results showed that anticipated pleasure increased more in the imagery-enhanced activity scheduling condition compared to control conditions in Study 1, but not Study 2. Across both studies, conditions did not differ regarding changes in anticipated reward/mastery, motivation, or behavioral engagement. The present findings indicate that although mental imagery may enhance anticipated pleasure in non-clinical individuals, its effects in participants experiencing anhedonia remains to be further investigated.

想象明天，你现在无法感受到的——快感缺乏症在意象增强行为激活中的作用

初步证据表明，在非临床样本中，以心理意象为基础的奖励活动可以增强预期的愉悦感、动机和行为参与，但其对体验快感缺乏症（快感/兴趣丧失）的个体的影响尚不清楚。研究1 （N = 90）在未选择的样本中对比了图像增强的活动调度与两种仅调度的控制条件（提醒/无提醒控制）。研究2 （N = 108）比较了轻度至中度快感缺乏个体的图像增强活动安排与两种对照条件（中性图像/动机性言语推理）。两项研究都测量了实验室中活动评估（预期快乐、预期奖励/掌握、动机）的变化，以及随后7天内的行为参与度。此外，研究2评估了心率作为各种情况下情绪反应的心理生理指标。结果表明，与研究1中的对照条件相比，在图像增强的活动计划条件下，预期快乐增加更多，但研究2中没有。在这两项研究中，在预期奖励/掌握、动机或行为参与方面的变化没有什么不同。目前的研究结果表明，尽管心理意象可能会提高非临床个体的预期愉悦感，但它对经历快感缺乏症的参与者的影响仍有待进一步研究。

期刊介绍： The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
