Katerina, The color stroop times are in ms, 1000ms = 1s.
Those values in the normal stroop report are in log(rt-in-ms). You can transform log(rt) to rt by using e^x, the =exp() function in excel, for example. So exp(6.353) = 574 ms, or about 1/2 of a second. You are really better off computing your own statistics from the trial-by-trial data found in the other files, rather than using the rather crude summary statistics reported there. You can use whatever averaging function you want then, and remove outliers at will. Best, Shane > Dear Shane, dear all, > > I would need a helping hand regarding the Stroop test data output.
