Social Network Aggression Task (SNAT) - Stories

The Leiden Consortium on Individual Development (L-CID) study was founded by Marinus van IJzendoorn, Eveline Crone, Marian Bakermans-Kranenburg and Rutger Engels in 2013. It was developed as one of four work packages of the overarching Consortium on Individual Development (CID). The L-CID study is a large-scale longitudinal intervention study in which 500 families with same-sex twins are followed over a six year period. L-CID has a cohort-sequential design with two cohorts: an early childhood cohort (ECC), aged 3-4 at wave 1, and a middle childhood cohort (MCC), aged 7-8 at wave 1. Annual assessments consist of alternating lab- or home visits during which behavioral and neurobiological data are collected. The collected data allow, among others, for testing which child characteristics shape the effect of (manipulated) environmental factors. The aim of L-CID is twofold: 1. To investigate the development of social competence and behavioral control in children between 3 and 14 years old; 2. To dissect the reason why not all children are equally responsive to variations in the social environment.

莱顿个体发展研究联盟（Leiden Consortium on Individual Development）研究项目由Marinus van IJzendoorn、Eveline Crone、Marian Bakermans-Kranenburg与Rutger Engels于2013年发起成立。该项目作为综合性个体发展联盟（Consortium on Individual Development，简称CID）下设的四个工作包之一研发而成。L-CID研究属于大型纵向干预研究，共纳入500个抚养同性双胞胎的家庭，追踪周期长达6年。研究采用队列序列设计，包含两个队列：幼儿队列（early childhood cohort，简称ECC，第一波测评时年龄为3~4岁）与童年中期队列（middle childhood cohort，简称MCC，第一波测评时年龄为7~8岁）。年度测评采用实验室访问与家庭访问交替进行的形式，在此期间采集行为学与神经生物学数据。所获数据可用于检验哪些儿童个体特征会调节经操控的环境因素的效应，亦可支撑多项其他相关研究。L-CID的研究目标包含两点：其一，探究3~14岁儿童的社会能力与行为控制能力发展规律；其二，解析为何并非所有儿童对社会环境变化的响应程度存在差异。
