title: Examination of the Effects of Intelligence on the Test of Variables of Attention for Elementary Students.
abstract: OBJECTIVE
  To examine the performance differences on the Test of Variables of Attention (TOVA) among different IQ level groups.
  
  
  METHODS
  The present study examined the results of the TOVA with 138 elementary students aged 6 to 10 years who were assigned to one of four different groups based on their scores from the Wechsler Nonverbal Scale of Ability (WNV; low average: IQ < 90, average: IQ between 90 and 109, high average: IQ between 110 and 119, superior: IQ between 120 and 129, and very superior: IQ > 129). The latter two groups were combined.
  
  
  RESULTS
  On all TOVA measures (response time, response time variability, errors of omission and commission, and ADHD scores), intellectual functioning significantly influenced performance.
  
  
  CONCLUSIONS
  The results of the present study indicate that performance on the TOVA was affected by intellectual functioning.
