Hi Gang
Thank you for your quick reply and for the suggestions. You are correct, I would want to model both phases of the task, decision and outcome. I have never used a model-free approach as per your suggestion, but I will certainly look into using TENT or CSPLIN as it sounds like that could be a fruitful approach. If I wanted to compare that, however, to a standard double gamma HRF would it be appropriate to use SPMG2 or GAM? Or alternatively, would something like dmBLOCK be better?
Thank you again for your assistance.
