Hi all,
My experiment consists of two tasks (with 4 conditions each) separated by 10 minutes. Some subjects perform taskA before taskB whereas other subjects perform taskB first. For first level analysis I used a 2x2 flexible factorial design. When I compare taskACondition1 with taskBCondition1 at second level I find some significant voxels. My question is, does SPM control for the order of the tasks at first level? Or could the difference I'm finding at second level be explained by task order?
Thank you!
Michael
