Hi all,
We are attempting to do an analysis for subjects that came in on two different days to perform two similar but different tasks (one learning condition, one control). Each of the tasks is structured such that there are 30sec rest epochs alternating with 30sec active (typing) epochs for a total of 12.5 minutes (the task begins and ends with rest). We are trying to compare the typing period for the control task to the typing period for the learning task.
We currently have first-level analyses of each of the tasks (active condition vs. null rest condition). Can we do within-subject comparisons and then do a group analysis on those? Or did we need to concatenate the learning and control conditions in the first-level analysis? If that is the case, how would you suggest that we do this?
