Abstract

Emotion-related impulsivity is an important behavioural phenotype in clinical psychology and public health. Here, we test the hypothesis that emotion-related impulsivity moderates the effects of arousal on cognition using pharmacological manipulation. Participants completed a measure of emotion-related impulsivity, four cognitive tasks tapping onto different facets of impulsive behaviours, and a blinded arousal manipulation using yohimbine hydrochloride, which acts on noradrenergic receptors. Our findings suggest that emotion-related impulsivity moderates the role of arousal on impulsive performance on the Information Sampling Task. As expected, more severe emotion-related impulsivity was related to more impulsive decisions in the yohimbine but not in the placebo group. Results provide some of the first experimental evidence that emotion-related impulsivity is related to differential behavioural responses in the face of high arousal. Despite this preliminary support, we discuss findings for one task that did not fit hypotheses, and provide suggestions for replication and extension.

情绪相关冲动调节唤醒对反思冲动的作用

情绪相关冲动是临床心理学和公共卫生领域的一种重要行为表型。在这里，我们通过药物操作来检验与情绪相关的冲动调节唤醒对认知的影响的假设。参与者完成了一项与情绪相关的冲动性测量，四项针对冲动行为不同方面的认知任务，以及使用盐酸育亨宾（作用于去甲肾上腺素受体）进行的盲唤醒操作。我们的研究结果表明，在信息采样任务中，情绪相关的冲动调节了唤醒对冲动表现的作用。正如预期的那样，育亨宾组更严重的情绪相关冲动与更冲动的决定有关，但安慰剂组没有。研究结果首次提供了一些实验证据，证明情绪相关的冲动与面对高唤醒时的不同行为反应有关。尽管有这种初步的支持，我们还是讨论了一项不符合假设的任务的发现，并为复制和扩展提供了建议。

期刊介绍： Pharmacology Biochemistry & Behavior publishes original reports in the areas of pharmacology and biochemistry in which the primary emphasis and theoretical context are behavioral. Contributions may involve clinical, preclinical, or basic research. Purely biochemical or toxicology studies will not be published. Papers describing the behavioral effects of novel drugs in models of psychiatric, neurological and cognitive disorders, and central pain must include a positive control unless the paper is on a disease where such a drug is not available yet. Papers focusing on physiological processes (e.g., peripheral pain mechanisms, body temperature regulation, seizure activity) are not accepted as we would like to retain the focus of Pharmacology Biochemistry & Behavior on behavior and its interaction with the biochemistry and neurochemistry of the central nervous system. Papers describing the effects of plant materials are generally not considered, unless the active ingredients are studied, the extraction method is well described, the doses tested are known, and clear and definite experimental evidence on the mechanism of action of the active ingredients is provided.
