为什么有的人比其他人能够取得更大的成功？寻找成功的秘诀是心理学和教育学的一个重要目标。过去十年来，大量研究发现一种被新开发出来的人格特质——毅力，能够稳定地预测个体在各个领域的成就。虽然毅力的研究取得了重大进展，但还很少有研究探讨毅力的培养机制。另外，目前关于毅力的神经机制的研究还处于起步阶段，毅力与大脑的关系仍然不清楚。本项目以青少年毅力人格为研究对象，围绕“家庭教育因素如何影响毅力及其神经网络基础”这一关键科学问题，基于申请人先前关于毅力的系列研究成果，依托四川大学华西磁共振研究中心组建跨学科研究团队，结合心理测量技术和多模态磁共振成像技术，运用人脑连接组学的最新方法，系统探讨家庭教育因素对毅力及其神经网络的影响机制。本项目将填补国内毅力研究的空白，有助于丰富毅力的理论研究，并为未来研究者开展毅力的教育和干预训练提供科学依据。

Why do some people achieve more than others? Searching for the secret to success is one major goal in the field of psychology and education. Over the past decade, abundant studies have suggested that a newly explored personality trait named “grit” can predict achievement-related outcomes in many professional domains. Although great advance has been made in the field of grit research, relatively few studies have investigated the influential factors of grit. In addition, few investigations have explored the association between grit and the brain, the neural basis of grit remains largely unknown. Focusing on adolescent’s trait grit, this project will concentrate on the scientific question that how family education affects behavioral and neural mechanisms of grit. Based on applicant’s previous series of study findinds on grit, with support from Huaxi MR Research Center of Sichuan University, we will construct a multi-disciplinary research team. Combining the psychometric techniques and multimodal magnetic resonance imaging techniques, this project will use the methods of human brain connectome to systematically investigate the behavioral and neural mechanisms of how family education affects grit. Our research may fill in the gap of Chinese grit studies, enrich the theoretical studies of grit, and provide the empirical evidence that can be used by future researchers to develop corresponding educational program and interventions to improve grit.
