dc.description.abstractThe gaze and motor performance of adolescent males with Attention-Deficit /Hyperactivity disorder (ADHD) and age-matched controls was determined in a computer-based simulation of a table tennis task used previously by Rodrigues et al (2002) and Vickers et al (2002). The Temporal Processing Task (TPT) was developed using the same time parameters and included visual cues that indicated two target locations to which a served ball was to be returned. During the long duration (LD) condition, the target was illuminated so that two seconds was available to prepare and respond, while in the short duration (SD) condition only 450 ms was available. Similarly to Vickers et al, the ADHD group was less accurate than the control group, and they also had irregular arm velocity at contact. However, contrary to Vickers et al, no group differences were found for gaze frequency, or the onset or duration of the quiet eye period. New findings were also found in the TPT that were not present in the previous studies. Movement time onset was significantly earlier for the ADHD group during successful LD trials, and participants from both groups tended toward a centralized fixation that was not apparent in the real task. The TPT did not appear to place the same pursuit tracking demands on the participants as did the actual task. The results cast some doubt upon the ecologically validity of computer-based tasks for testing ADHD participants, and suggest that ADHD research, particularly that which involves gaze behaviors, be performed using tasks with high ecological validity. The differences between the real task and the TPT are examined, and the results are discussed relative to disinhibitory models, as well as the potential implications of computer-based activities for those with ADHD.en
