External Email - Use Caution Great, thanks so much Doug- this setup makes sense to me. However, isn’t it a problem that the brain regions associated with the contrast for -a 3 and the contrast for -a 4 would be the same for trials that subjects rate as 1 (self-relevant) vs 0 (not self-relevant)? Could we code it as 2 (self-relevant) and 1 (not self-relevant)?
