Deficient visuomotor tracking in children with attention-deficit hyperactivity disorder (ADHD) has been described, but the specific influence of attention on this deficit has not yet been elucidated. The present study compares visuomotor tracking under different conditions of attentional loading in children with ADHD with that of age-matched controls. A computerized visuomotor attentional tracking test that incorporated several levels of distraction was administered to 131 typical children. The same test, as well as a standard Matching Familiar Figures Test and the Proteus Maze test, was administered to 32 children with ADHD and 21 control children. Significant differences between children with ADHD and controls in visuomotor attentional tracking indices that relate to pacing and the accuracy of the tracking movements were observed under all levels of distraction. In parallel, a significant performance decrement was observed in all subjects once distraction was introduced. Discriminant analysis, based on the visuomotor attentional tracking test findings, resulted in correct classification of 92.3% of the typical children and 46% of the children with ADHD. Significant correlations between Matching Familiar Figures Test latency, as well as errors and visuomotor attentional tracking indices, were noted among children with ADHD when the visuomotor attentional tracking did not involve distraction. Under distraction, these correlations extended to the control group as well. In conclusion, visuomotor tracking appears to reflect the availability of attentional resources in general and is significantly affected by the presence of ADHD in particular. These results have potential implications related to the evaluation of children with ADHD on and off drugs. (J Child Neurol 2006;21:502—507; DOI 10.2310/7010.2006.00135
To assess the reliability and validity of the human figure drawing test among children with attention-deficit hyperactivity disorder (ADHD) and/or learning disability, boys (n = 136) between the ages of 8 and 10 years, with either or both ADHD and learning disability, were included. Two drawings were used: person and house, tree and person. The drawings were analyzed using the Koppitz emotional and developmental scales. Conners teacher and parent rating scales and the Matching Familiar Figure Test were administered. High intertest reliability for the emotional scale and a significant negative correlation between the 2 scales were found. The reported anxiety and learning were significantly correlated with the cognitive score. A combination of cognitive and emotional items resulted in 67% correct classification of ADHD and learning disability. This test can be used as part of the assessment of ADHD/learning disability.
