A cognitive psychologist conducted an experiment to investigate whether classroom environment affects memory retention. One group of participants studied a list of 25 key historical facts while sitting in a room with bright, natural lighting. A second group studied the same list of facts in a room with dim, artificial lighting. The psychologist recorded how many historical facts each participant correctly recalled in a test 30 minutes later.
