The aim of the Leiden Consortium on Individual Development (L-CID) is twofold: 1. to investigate the development of social competence and behavioral control in children between 3 and 14 years old and 2. to dissect the reason why not all children are equally responsive to variations in the social environment. L-CID is a large-scale longitudinal intervention study in which 500 families with same-sex twins are followed over a six-year period. Annual assessments consist of alternating lab- or home visits during which behavioral and neurobiological (EEG/MRI) data are collected. The collected data allows, among others, for testing which child characteristics shape the effect of (manipulated) environmental factors.

The L-CID is embedded within the Developmental Psychology unit at Leiden University (Prof. Eveline Crone) and the section Clinical Child and Development Studies at VU University Amsterdam (Prof. Marian Bakermans-Kranenburg). Prof. Marinus van IJzendoorn is involved as scientific advisor (Erasmus University Rotterdam and Cambridge University UK).  See: www.samen-uniek.com

L-CID is part of the National Consortium on Individual Development (CID) which aims to understand and predict how the interplay of child characteristics and environmental factors results in individual differences in the development of social competence and behavioral control of the child. The consortium involves researchers from Utrecht University, Leiden University, University of Amsterdam, University of Groningen, Erasmus University Rotterdam, Radboud University Nijmegen, and VU University Amsterdam. The consortium has been funded by a ‘Gravity’ grant of the Ministry of Education, Culture and Science. The Netherlands Organization for Scientific Research (NWO) conducted the selection procedure at the request of the Ministry. For more information about CID, see: www.individualdevelopment.nl
