Memory for Rooms Test: A) Rooms and sample objects: Each room contained 12 target objects. Target and distracter objects were counter balanced across rooms and across participants. B) Object and source memory fMRI paradigm: Participants viewed pictures of objects, which were present in the rooms during encoding (targets) and some that were not (distracters). They were asked to indicate (using a response button) whether each object was old or new, and also for objects that were identified as “old” to indicate the source (which room the object seen in). The order of these responses choices was counterbalanced between participants. A variable length of fixation was viewed between trials.
