Note: Performance data (RT for correct trials, CV for correct trials, commission error, omission error, accuracy) are presented for target and standard trial data from oddball blocks. Data for intermedication comparison (i.e., versus ) are shown for ADHD subjects. Mean values were calculated by first subtracting the values of from those of for each subject and then averaging the resulting values across subjects. SD was calculated similarly. value and value and statistical significance were the results of two-sample t-tests between and . , difference between post- and pre-MPH; , difference between post- and pre-placebo; SD, standard deviation; , value; , value. Statistical significances are presented as follows: *; **; and ns, not significant.
