Received many requests for this. I've started putting one together (see link below). The strange looking cells in it are:
Code:
rt:57,-1<-999
rt:-1,57<-999
57 as usual is the keycode for the spacebar. -1 is the new code used to represent no response. <999 normally means jump to trial 999 when the trial is over and then resume. In v2006, you can add a negative sign as in <-999 to jump NOW without finishing the trial. The subject never sees the rest of the trial. 999 is the X. So if you don’t jump immediately to 999 (and get the X) then you get the O which is at the end of each trial.
Hope that makes sense. No guarantees as far as the design of the GNAT goes, but I think it's a good start. If anyone makes some fixes to this, let me know and I'll post them here.
