title: Assessing Attention Deficit by Binocular Rivalry.
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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  The differences between groups in relation to the BR indicators can be attributed to the activity of involuntary inhibition.
