Clinical Trial Summary

This study evaluates approximate number sense (ANS) in children, adolescents, and adult women with Turner syndrome compared to age-matched healthy peers. One primary aim of this project is to assess the effectiveness of an online ANS training tool in enhancing complex mathematics ability. Participants will undergo weekly training sessions in their own home. Half of the participants will complete 2 training sessions a week for 8 weeks, and the second half will complete 1 training session for 8 weeks.
