ABSTRACT
OBJECTIVE:
To determine whether the frequency and duration of the periods of suppression of a percept in a binocular rivalry (BR) task can be used to distinguish between participants with ADHD and controls.METHOD:
A total of 122 participants (6-15 years) were assigned to three groups ADHD-Combined (ADHD-C), ADHD-Predominantly Inattentive (ADHD-I), and controls. They each performed a BR task and two measures were recorded alternation rate and duration of exclusive dominance periods.RESULTS:
ADHD-C group presented fewer alternations and showed greater variability than did the control group; results for the ADHD-I group being intermediate between the two. The duration of dominance periods showed a differential profile In control group, it remained stable over time, whereas in the clinical groups, it decreased logarithmically as the task progressed.CONCLUSION:
The differences between groups in relation to the BR indicators can be attributed to the activity of involuntary inhibition.Palavras-chave
