IQ predicts neuropsychological performance in children.
BACKGROUND
This study examined whether IQ predicts neuropsychological performance among children with varying ability levels.


METHODS
177 children/adolescents were subdivided as Below Average (BA; N = 71; IQ = 60-85), Average (A; N = 72; IQ = 90-110), or Above Average (AA; N = 34; IQ = 115-140) in IQ. Assessments included intelligence, achievement, memory, and executive functioning measures.


RESULTS
Group differences were found on all tests (p < .001). Planned comparisons revealed differences between BA and A on seven variables, and between A and AA on five variables with small-to-medium effect sizes. Correlations were found between IQ and neuropsychological functioning and varied by group membership.


CONCLUSIONS
In children, IQ predicts neuropsychological performance differentially based upon ability level, with stronger relationships shown in lower IQ ranges.
