I need to conduct experiment for my Masters Cognitive Psychology module using the cognitive approach. The
experiment is required to be a manageable 2x2 design. I have chosen my topic, which is memory, specifically I wish to conduct the eyewitness testimony experiment. I am concerned that I may not have property understood what the independent and dependent variables should be. I´d like to test the effect of wording on immediate recall. For example, asking misleading questions and unbiased questions. I therefore wanted to ask if the appropriate setup for the experiment should be: Separate the participants / witnesses into 2 groups. Both groups watch the same scene. The 1st group is given misleading questions and the 2nd group being given unbiased questions to test their recall. However, my understanding is that this is not sufficient for a 2x2 design and needs another layer/level. If I were therefore to then give the 1st group the unbiased questions and the 2nd group the misleading questions, does that qualify the requirement of the 2nd level within a 2x2? Or am I going down completely the wrong track?
