Comparitive Study of Working Memory and Fluid Intelligence in three Subgroups of Children with ADHD

This study compares working memory and fluid intelligence in children with three ADHD subtypes.

Forty ADHD children ageing 7 to 11 years old were recruited using a cluster random sampling method. CSI-4 symptoms questionnaire, Wechsler intelligence test for children, Cattell's intelligence Test were used to measure ADHD, working memory, and fluid intelligence respectively.

The results of ANOVA, Tukey, and Kruskal-Wallis tests revealed a positive relationship between working memory and fluid intelligence, also there was a difference between the three children groups in working memory and fluid intelligence variables.

This research suggests that a relationship exists between working memory and fluid intelligence and ADHD.
