| Primary | Stop Signal Reaction Time (SSRT) as Derived From the Stop Signal Reaction Time Paradigm | SSRT measures response execution (go trials) and response inhibition (stop trials). Go trials consist of stimulus (airplane). Child to press response button corresponding to direction airplane is pointing. Stop trials consist of go trial and audible stop signal. Initial delay between go trial and stop signal = 250 msec. If child succeeded in inhibiting response, delay on next stop trial increased by 50 msec, otherwise, delay decreased by 50 msec. SSRT = subtract mean delay from mean go signal reaction time. Lower scores mean better ability to suppress response when presented with stop signal. | All efficacy information is summarized and/or presented in data listings based on the Safety sample: Includes all patients who were randomized to double-blind treatment and received at least one dose of study drug. | Posted | | Least Squares Mean | Standard Error | milliseconds (msec) | | Baseline and Week 4 of initial therapy and Week 4 of crossover therapy | | | | ID | Title | Description |
