Brief summary
This project aims at validating a new neuropsychological test to measure voluntary and involuntary attention for clinical use to diagnose attentional deficits. This project proposes: * a test-retest procedure in healthy subjects aged from 6 to 90 year-old; * testing in attention deficit hyperactivity disorder (ADHD) patients before psychostimulant treatment; * testing in attention deficit hyperactivity disorder (ADHD) patients before psychostimulant treatment.
Interventions
OTHERexperience 1 : Competitive attention test in healthy participants
Comparison of behavioral measures (reaction times and percentage of correct responses) obtained twice with the CAT test in healthy participants (2 to 6 weeks apart).
OTHERexperience 2 : Competitive attention test in patients with ADHD with no treatment
Behavioral (reaction times and percentage of correct responses) and Electroencephalography (EEG) measures obtained with the CAT test in patients with ADHD with no treatment.
OTHERexperience 3 :Competitive attention test in patients with ADHD with psychostimulant treatment
Behavioral (reaction times and percentage of correct responses) and EEG measures obtained with the CAT test in patients with ADHD before and after psychostimulant treatment.
