This study investigates genetic and environmental influences on 57 psychological traits in emerging adulthood using UK twins, finding significant genetic contributions and their associations with health and educational outcomes.

The paper introduces a gamified cognitive ability measure, Pathfinder, which shows heritability and genetic prediction of general cognitive ability.

This paper improves the prediction of behaviour problems using multi-GPS, cross-age and cross-rater composites, increasing predictive variance from less than 2% to up to 6%.

The paper assesses spatial orientation and object-based spatial abilities in a large twin sample, finding a common genetic network underlying all spatial abilities.

This study examines how genomic measures and socioeconomic status predict educational achievement across school years in UK children.
