Dear Yina, Can you please clarify the hypothesis you want to test? From my understanding, you want to test whether the similarity between task X and task Y is different between the two groups? Am I right? Then the straightforward way is to test the interaction between group and task. I don't understand the rationale that you want to test the differences between two conjunctions.
