摘要

目的 降低认知努力的动机是抑郁症的一个临床相关特征,但却未得到充分研究。初步研究表明,与非抑郁症患者相比,抑郁症患者和情感障碍患者可能更不愿意为获得奖励而付出认知努力。然而,这种情况在多大程度上是由于对奖赏的期望降低所致,以及是否可以通过改变对奖赏的情感期望来提高花费努力的意愿,这些都是未知数。本研究的目的是研究抑郁障碍、失乐症和情感预期对认知努力奖赏支出的影响。方法将抑郁障碍参与者(85 人)和非抑郁障碍参与者(79 人)随机分配到高预期条件下或中性预期条件下,前者旨在提高个体对认知努力累进比率任务中可获得奖赏的预期,后者则不试图改变预期。我们收集了参与者的预期快乐评分,然后让他们完成认知努力累进比率任务。结果与结论:虽然预期操纵没有成功,但我们发现心理障碍组与参与者自我报告的快乐预期相互作用,从而预测了他们的认知努力支出。在焦虑症组中,对快乐的期望越高,付出的努力就越大。相反,在非焦虑症组中,无论期望值如何,努力程度都相对较高。失乐症进一步调节了这一关系;在抑郁障碍组中,随着失乐症的加重,预期快乐与努力支出之间的关系减弱。本文讨论了治疗抑郁症的意义。

The Effects of Affective Expectations on Willingness to Expend Cognitive Effort in Dysphoric and Non-Dysphoric Individuals

The Effects of Affective Expectations on Willingness to Expend Cognitive Effort in Dysphoric and Non-Dysphoric Individuals

Purpose

Reduced motivation to expend cognitive effort is a clinically relevant but understudied feature of depression. Preliminary research indicates that depressed and dysphoric individuals may be less willing to expend cognitive effort for reward than non-depressed individuals. However, the extent to which this is due to reduced expectations of reward, and whether willingness to expend effort can be increased by altering affective expectations of reward, are unknown. The purpose of this study was to examine the effects of dysphoria, anhedonia, and affective expectations on cognitive effort expenditure for reward.

Methods

Dysphoric (n = 85) and non-dysphoric participants (n = 79) were randomly assigned to either a high expectancy condition designed to increase individuals’ expectations of a reward that could be earned during a cognitive effort progressive ratio task or a neutral expectancy condition that did not attempt to alter expectations. Expected pleasure ratings were collected, and then participants completed the cognitive effort progressive ratio task.

Results and Conclusions

The expectancy manipulation was unsuccessful, but we found that dysphoria group interacted with participants’ self-reported expectations of pleasure to predict their cognitive effort expenditure. Within the dysphoric group, higher expectations of pleasure were significantly associated with greater effort. In contrast, within the non-dysphoric group, effort was relatively high regardless of expectations. Anhedonia further moderated this relationship; in the dysphoric group, the relationship between expected pleasure and effort expenditure weakened as anhedonia increased. Implications for the treatment of depression are discussed.
