## Different stimuli phase1/phase2

##### Different stimuli phase1/phase2
 Author Message essematta Group: Forum Members Posts: 2, Visits: 27 Hi, I am trying to design a study but I am encountering some issues in getting the desired outcome. I have two lists of stimuli (text). -    List 1: 6 information presented statements-    List 2: 6 information presented as questions The information included in the two list are identical, only the format (declarative vs interrogative) changes./1 = "A"/2 = "B”/3 = "C”/4 = "D"/5 = "E"/6 = "F”/1 = "A?"/2 = "B?”/3 = "C?”/4 = "D?"/5 = "E?"/6 = "F?”In a first phase, participants should see 3 questions and 3 statements, but it is important that the 3 questions include different items from those presented in the 3 statements.Then, in a second phase, participants should see the same 3 questions and 3 statements seen in phase 1 (repeated info), plus the 3 questions and 3 statements not seen in phase 1 (new info). Also for the new info, I want the 3 questions to include different items from those presented in the 3 statements.Could you help me with that?
