Cumulative RT for Two Events

[Jordan Schoenherr]

I'll just post on my own thread:

So it seems that each event that is given a cumulative value is placed
in the RT recording sequence and RT feedback is provided for the final
event. I'm still interested in whether I can use the acc from the
first event in the feedback sequence?
