The first two years of life are foundational for lifelong physical and psychological health. This project will combine the behavioural genetic twin design, a powerful tool for estimating heritability and environmental influence, with DNA-based methods, state of the art neuropsychological and biopsychosocial assessments. It will investigate the links between genes, brain, and behaviour during the infant years. Only recently are the challenges of recruiting and assessing infant samples being overcome in order to obtain advanced neuropsychological and behavioural assessments. This study will involve sophisticated computational modelling to address fundamental questions about the causes of infant development.
