Results of Disengagement of Attention task. Scores from the clinician (Clin.), automatic method (Automatic), a psychiatrist (Psy.), and two students (St. 1 and St. 2) for each trial. A trial is considered either as “passed” (Pass), “delayed” (Del), or “stuck” (Stck) depending on whether the child disengages from the first object in less than 1 s, between 1 and 2 s, or more than 2 s, respectively. We also present the automatically computed delay that the child takes to disengage. Note that we consider of a second margin for each delay to accommodate human error of making a live judgment.
