sstfsg Integer Recommended SST Failed Stop RT Go RT: A comparison between the reaction times on Go trials versus those on a Failed Stop trial. Research suggests that the Failed stop reaction time should be shorter than the Go reaction time. This measure is reported as Yes = 1, No = 0. Subjects should output 'yes' in ideal situations.You would hope to see the mean reaction time from all the assessed Failed Stop trials being less than (faster) the mean reaction time from all assessed Go trials.
