Dear Guillaume and others,
Thank you for the suggestion, I do have a question regarding the differential contrasts you mentioned. Am I correct in stating that using just those 2 contrasts ([1 -1 0] and [0 1 -1] rather than all 6 possible combinations) is sufficient because the ANOVA at the second level contrasts them?
Additionally, since the subject factor no longer needs to be included in the 2nd level does this mean I should list my measures as independent too?
