Description
Monica Luciana, Kelly A. Duffy, and Wesley K. Thompson examined the structure of thinking skills over time in a 2026 analysis of the ABCD study. This large United States study follows children's brain and cognitive development. Its test battery shrank across waves, which threatened the comparability of scores.
Using a Bayesian statistical method, they extracted three components from baseline, year two, and year four data: general ability, executive function, and learning and memory. Even as the battery fell from nine tests to five, the same three part structure fit well, with similar task loadings. Scores across versions correlated strongly. The shrunken battery still showed age and practice gains, and component scores linked in distinct ways to mental health measures and brain scan activity during a working memory task.
