Abstract
Introduction: This study examined whether IQ predicts neuropsychological performance among children with varying ability levels. Method: 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. Discussion: In children, IQ predicts neuropsychological performance differentially based upon ability level, with stronger relationships shown in lower IQ ranges.
