Abstract

There are competing theoretical hypotheses regarding the consequences of early adversity, such as childhood maltreatment, for individuals’ autonomic nervous system activity. Research examining potential implications of child maltreatment for sympathetic nervous system activity, specifically, is scarce. In this preregistered study, we examined whether childhood maltreatment history is associated with pregnant adults’ sympathetic responses to different stressors. This population is particularly relevant, given potential intergenerational consequences of pregnant individuals’ physiological responses to stress. Pregnant women's (N = 162) electrodermal levels were recorded while completing the Trier Social Stress Test (TSST), which elicits social-evaluative threat, and while watching a video of an unfamiliar infant crying, which was intended to activate the attachment system. Pregnant women's retrospective reports of childhood maltreatment were negatively associated with their electrodermal reactivity to the TSST and to the video of the infant crying. Follow-up analyses indicated that these associations were specific to reported experiences of childhood abuse and not childhood neglect. Altogether, these findings indicate that self-reported childhood maltreatment experiences, and childhood abuse in particular, may result in blunted activity of the sympathetic nervous system in response to multiple types of stressors.

童年虐待与孕妇对压力的电热反应性
关于早期逆境(如儿童虐待)对个人自律神经系统活动的影响,存在着各种相互竞争的理论假设。具体来说,有关儿童虐待对交感神经系统活动潜在影响的研究还很少。在这项预先登记的研究中,我们考察了儿童虐待史是否与怀孕成年人对不同压力源的交感神经反应有关。考虑到孕妇个体对压力的生理反应可能产生的代际后果,这一人群的研究尤为重要。我们记录了孕妇(162 人)在完成特里尔社会压力测试(TSST)和观看陌生婴儿啼哭视频时的皮电水平,前者可引起社会评价性威胁,后者旨在激活依恋系统。孕妇对童年遭受虐待的回顾性报告与她们对 TSST 和婴儿哭泣视频的皮电反应呈负相关。后续分析表明,这些关联只与报告的童年虐待经历有关,而与童年忽视经历无关。总之,这些研究结果表明,自我报告的童年受虐待经历,尤其是童年受虐待经历,可能会导致交感神经系统在应对多种压力时活动减弱。

期刊介绍: Developmental Psychobiology is a peer-reviewed journal that publishes original research papers from the disciplines of psychology, biology, neuroscience, and medicine that contribute to an understanding of behavior development. Research that focuses on development in the embryo/fetus, neonate, juvenile, or adult animal and multidisciplinary research that relates behavioral development to anatomy, physiology, biochemistry, genetics, or evolution is appropriate. The journal represents a broad phylogenetic perspective on behavior development by publishing studies of invertebrates, fish, birds, humans, and other animals. The journal publishes experimental and descriptive studies whether carried out in the laboratory or field. The journal also publishes review articles and theoretical papers that make important conceptual contributions. Special dedicated issues of Developmental Psychobiology , consisting of invited papers on a topic of general interest, may be arranged with the Editor-in-Chief. Developmental Psychobiology also publishes Letters to the Editor, which discuss issues of general interest or material published in the journal. Letters discussing published material may correct errors, provide clarification, or offer a different point of view. Authors should consult the editors on the preparation of these contributions.
