Dr. Aris conducted a study investigating the impact of a daily spatial navigation mobile game on spatial memory in a sample of 12 older adults (aged 70+). He recruited participants using volunteer sampling via a flyer placed on a community noticeboard in a single retirement village. He measured spatial memory using a self-report rating scale where participants estimated how often they misplaced daily items.
