The main aims of this study were to develop norms for the Wisconsin Card So
rting Test in 6- to 11-year-old children in Taiwan; to explore the effect o
f sex, age, birth order, number of siblings, and parental education on WCST
performance in 6- to 11-year-old children; and to make a comparison of WCS
T performance between children in Taiwan and the USA. The results of this c
omparison of developmental norms of school children in Taiwan and the Unite
d States may facilitate the WCST as a clinical or research instrument in co
mbination with other test procedures to assess aspects of cognitive and neu
ropsychological functioning of school children.
