Help for a Script to contrast activity based on stimtimes

Hello,

Below is a script for recognition memory study with 6 runs (120 seconds each), words presented for 2 seconds each; words were either studied by drawing, writing, listing, or were new lure words. Our goal is to contrast activity during memory for each of the 4 target word types (draw, write, list, and new). I was hoping to check this script to ensure that it makes sense. As well, is this the best way to run this analysis?

Thank you so much,
Nicole

Nicole,

Our goal is to contrast activity during memory for each of the 4 target word types (draw, write, list, and new).

If those contrasts in the script directly address your research hypotheses, then the script looks fine to me. The following lines are unnecessary because you’re assuming a hypothetical hemodynamic response curve in your model:

-iresp 1 irespwrite_tar \
-iresp 2 iresplist_tar \
-iresp 3 irespdraw_tar \
-iresp 4 irespnew_tar \
-sresp 1 stddevwrite_tar \
-sresp 2 stddevlist_tar \
-sresp 3 stddevdraw_tar \
-sresp 4 stddevnew_tar \
