Results of Visual Tracking 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 “passed” (Pass), “delayed” (Del), “interrupted” (Int), “partial” (Prt), or “no tracking” depending on how smoothly the child visually tracks the object.
