Developmental population neuroscience: emerging from ICHBD

The 3rd International Conference on Human Brain Development(ICHBD)was held during October 10–15,2017 in Nanning,Guangxi,China.ICHBD was initiated in 2014 by Drs.Xi-Nian Zuo,Olaf Sporns and Michael P.Milham(co-chairs),and has been consistently supported by a major international collaboration grant from Natural Science Foundation of China(81220108014).The goal of ICHBD is to bring together international scientists from a

Functional brain network mapping with dual regression

Functional magnetic resonance imaging(fMRI)is an in-vivo non-invasive technique for measuring brain activity with excellent spatial and good temporal resolution.Without performing explicit tasks,resting-state fMRI(rfMRI)is widely used to map the functional connectivity network(FCN),which refers to a large-scale network of interdependent or functionally connected brain regions and it could be detected by using different algorithms(Zuo

广西少数民族学龄前儿童身心发展规律研究

按人口比例抽取样本、构建少数民族群体心理发展队列是未来大规模队列建设的重要方向.作为个体毕生发展的奠基阶段,学龄前儿童的心理发展对学业成就、情绪调控和社会适应产生深远影响.本研究构建广西少数民族学龄前儿童心理发展队列,揭示12个少数民族聚居区学龄前儿童心理发展的特点规律.基于《学龄前儿童身心发展评估量表》,以在线方式采集132792名家长对学龄前儿童在探究与认知、社会性与情感、语言与交流、美感与表现和健康与体能等5个领域的发展数据.结果表明,学龄前儿童在探究与认知(median=4.03)、美感与表现(median=4.02)两个领域的发展高于社会性与情感(median=3.89)、语言与交流(median=3.81)和健康与体能(median=3.58);女孩在语言与交流(W=7.58×10^(7),P<0.001,Cliff’s delta=0.14)和美感与表现(W=6.55×10^(7),P<0.001,Cliff’s delta=0.16)领域的发展比男孩的水平高.健康与体能表现出显著的年级差异,小班幼儿健康与体能的发展优于中班和大班幼儿(H=4562.91,P<0.001,η^(2)=0.15);相比其他民族聚居区学龄前儿童,龙胜各族、大化瑶族和巴马瑶族的学龄前儿童身心发展水平相对较高.多个少数民族聚居区学龄前儿童身心发展存在性别差异.研究初步揭示了广西少数民族学龄前儿童身心发展的特点规律,为构建少数民族学龄前儿童脑智发育队列积累了前期基础,为制定契合少数民族学龄前儿童脑智发育特点的民族教育政策提供了数据支撑.
