People are more likely to engage in various suboptimal behaviors such as overeating, addictive behaviors, and short-sighted financial decision-making when they are under stress. Traditional dual-process models propose that stress can impair the ability to engage in goal-directed behavior so that people have to rely on habitual behavior. Support for this idea comes from a study by Schwabe and Wolf (2010), in which stressed participants continued to perform a learned instrumental behavior leading to a liquid after the liquid was devalued with a satiation procedure. Based on these findings, suboptimal behavior under stress is often seen as habitual. In the present study, we conducted a conceptual replication of the study by Schwabe and Wolf (2010). Instead of using a satiation procedure to achieve the outcome devaluation, we devalued outcomes through taste aversion. We did not replicate the pattern of findings by Schwabe and Wolf (2010). Our results indicate instead that stressed participants were sensitive to outcome values when the outcomes became truly aversive and hence that their behavior was goal-directed. This suggests either that (a) habitual processes are subject to boundary conditions or (b) the processes responsible for the findings of Schwabe and Wolf (2010) were never habitual to begin with. This may have far-reaching implications for explaining suboptimal behavior under stress in general. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

在结果贬值和味觉厌恶之后,目标导向和习惯性过程在压力下的食物消费中的作用。

当人们处于压力之下时,他们更容易做出各种次优行为,例如暴饮暴食、成瘾行为和短视的财务决策。传统的双过程模型提出,压力会削弱从事目标导向行为的能力,因此人们不得不依赖习惯性行为。对这一想法的支持来自 Schwabe 和 Wolf (2010) 的一项研究,在该研究中,压力大的参与者在通过饱食程序使液体贬值后,继续执行一种学习到的工具行为,导致液体产生。基于这些发现,压力下的次优行为通常被视为习惯性行为。在本研究中,我们对 Schwabe 和 Wolf (2010) 的研究进行了概念复制。不是使用饱和程序来实现结果贬值,我们通过厌恶口味贬低了结果。我们没有复制 Schwabe 和 Wolf (2010) 的发现模式。相反,我们的结果表明,当结果变得真正令人厌恶时,压力大的参与者对结果值很敏感,因此他们的行为是目标导向的。这表明要么 (a) 习惯性过程受边界条件的约束,要么 (b) 对 Schwabe 和 Wolf (2010) 的发现负责的过程从一开始就不是习惯性的。这可能对解释一般压力下的次优行为具有深远的影响。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。相反,我们的结果表明,当结果变得真正令人厌恶时,压力大的参与者对结果值很敏感,因此他们的行为是目标导向的。这表明要么 (a) 习惯性过程受边界条件的约束,要么 (b) 对 Schwabe 和 Wolf (2010) 的发现负责的过程从一开始就不是习惯性的。这可能对解释一般压力下的次优行为具有深远的影响。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。相反,我们的结果表明,当结果变得真正令人厌恶时,压力大的参与者对结果值很敏感,因此他们的行为是目标导向的。这表明要么 (a) 习惯性过程受边界条件的约束,要么 (b) 对 Schwabe 和 Wolf (2010) 的发现负责的过程从一开始就不是习惯性的。这可能对解释一般压力下的次优行为具有深远的影响。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。这可能对解释一般压力下的次优行为具有深远的影响。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。这可能对解释一般压力下的次优行为具有深远的影响。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。
