A cognitive psychologist is investigating the effects of divided attention on semantic memory retrieval. Participants in Group A are asked to recall a list of 15 previously studied historical facts while performing a continuous rhythmic finger-tapping task with their non-dominant hand. Participants in Group B are asked to recall the same list of 15 historical facts in silence with no concurrent task.
