项目摘要

DESCRIPTION (provided by applicant): This study seeks to improve our understanding of self-regulation and its role in emerging mental health problems by utilizing neurocognitive and physiological measures of self-regulation and examining their co- development during a period of marked plasticity (both neural and behavioral) and rapid CMS development. Effortful control (EC) and respiratory sinus arrythmia (RSA) are indicators of cognitive and emotion regulation, respectively. Despite solid evidence that these components of self-regulation are interrelated, there is almost no research examining the co-development of EC and RSA in young children. Specifically, there is little research examining how EC and RSA develop, predict, and potentially shape one another over time. Examining how individual differences in the development of EC predict changes in RSA, and vice versa, might clarify how particular deficits of attention, behavioral and/or emotional regulation develop. Low EC and RSA have been linked to mental health problems including anxiety, depression, and externalizing problems. Examining how neurocognitive and physiological indicators of self-regulation predict concurrent and later mental health problems in young children may identify key mechanisms in the development of psychopathology, and point to potential targets of intervention. The proposed research will assess 174 families with 3 year old children across three time points. Two thirds of the sample will be families of low-income or poverty backgrounds. Strains associated with low- income and poverty environments will increase the incidence of emotional and behavioral problems in children and observation of atypical self-regulatory development.

描述（由申请人提供）：本研究旨在通过利用自我调节的神经认知和生理测量方法来提高我们对自我调节及其在出现心理健康问题中的作用的理解，并在明显的可塑性（神经和行为）和快速CMS发展的时期检查其共同发展。努力控制（EC）和呼吸窦芳香族（RSA）分别是认知和情绪调节的指标。尽管有良好的证据表明这些自我调节组成部分是相互关联的，但几乎没有研究研究幼儿的EC和RSA共同开发。具体而言，几乎没有研究来研究EC和RSA如何随着时间的流逝而发展，预测和潜在地互相塑造。检查EC发展的个体差异如何预测RSA的变化，反之亦然，可能会阐明注意力，行为和/或情绪调节的特定缺陷。低EC和RSA与心理健康问题有关，包括焦虑，抑郁和外部化问题。检查自我调节的神经认知和生理指标如何预测幼儿的并发和后来的心理健康问题可能会确定心理病理发展中的关键机制，并指出潜在的干预靶标。拟议的研究将在三个时间点上评估174个有3岁儿童的家庭。样本的三分之二将是低收入或贫困背景的家族。与低收入和贫困环境相关的菌株将增加儿童情绪和行为问题的发生，并观察非典型的自我调节性发展。
