Early childhood is a sensitive period for learning and social skill development. The maturation of cerebral regions underlying social processing lays the foundation for later social-emotional competence. This study explored myelin changes in social brain regions and their association with changes in parent-rated social-emotional development in a cohort of 129 children (64 females, 0-36 months, 77 White). Results reveal a steep increase in myelination throughout the social brain in the first 3 years of life that is significantly associated with social-emotional development scores. These findings add knowledge to the emerging picture of social brain development by describing neural underpinnings of human social behavior. They can contribute to identifying age-/stage-appropriate early life factors in this developmental domain.
幼儿期是学习和社交技能发展的敏感期。社会加工相关脑区的成熟为后期的社会情感能力奠定了基础。本研究在129名儿童（64名女性，0至36个月，77名白人）队列中，探究了社会脑区的髓鞘变化及其与家长评定的社会情感发展变化之间的关联。结果显示，在生命的头3年里，整个社会脑区的髓鞘形成急剧增加，且与社会情感发展得分显著相关。这些发现通过描述人类社会行为的神经基础，为社会脑发育这一新兴图景增添了知识。它们有助于在这一发育领域识别适合年龄/阶段的早期生活因素。
