Dear list,
we´ve conducted an experiment with 3 different sessions/scanning days (S1,S2,S3). In each session pictures with emotional (E) and neutral (N) content were presented. We are mainly interested in the emotion specific activation between sessions. Hence, is it appropriate to compare e.g. S1E1-S2E2 or should we also take the neutral conditions into account e.g. (S1E1-S1N1)-(S2E2-S2N2)?
Thank´s in advance!
Albert
