The proposed research investigates whether exposure to a web-based training protocol designed to enhance executive control / multi-tasking abilities will improve cognitive performance in cognitively healthy older adults. Cognitively normal adults aged 60-75 will be randomized into three groups: 1) Web-based game with training strategy (Experimental); 2) Web-based game without training strategy (Active Control); 3) No intervention group (Passive control). Participants in groups 1 and 2 will be instructed to play the complex, high-demand online game, the Breakfast Game, for 10 one-hour sessions over 4 weeks. At study entry all participants will be asked to complete a cognitive assessment, health questionnaires, a blood exam and and education session on healthy aging. After the intervention, participants will be asked to repeat the cogntive assessment within 1-2 weeks, and after 3 months.
