What this Trial Is About
The goal of this accelerated longitudinal observational cohort study is to advance our understanding of cognitive variability in children aged 7 to 10 at first measurement. The CODEC study aims to integrate experience sampling methods, longitudinal designs, deep phenotyping cohorts, and state-of-the-art statistical methodologies to investigate three core questions: 1. How does cognitive variability differ between individuals? 2. What are the neural, psychological, and environmental mechanisms that underlie cognitive variability? 3. What are the long-term consequences and outcomes associated with differences in cognitive variability?
