Hi, I meet a new pronlem and hope you can help me .I am designing a Stop Signal Task, which prensent two stimulus.One is for going to press the key,after that ,the other one show meaning to withdraw.I want to the SOA between the two stimulus change according to the participant’s reaction .The orig…

Thanks. So, the SOA is the same on every trial because it is reset to 2.5 on each routine, and only incremented at the end of the trial. You could instead move soa = 2.5 to the “Begin Experiment” tab.
