Title: RCT of Two Speed of Processing Modes to Prevent Cognitive Decline in Older Adults
Brief Summary: This is second-generation study based on results from ACTIVE (Advanced Cognitive Training for Independent and Vital Elderly). This four-arm study is known as IHAMS (the Iowa Healthy and Active Minds Study). The investigators will formally test from an intent-to-treat perspective for differences on the primary and secondary outcomes based on whether participants were randomized to the basic on-site speed of processing training (SOPT) group (G1), to the on-site basic SOPT plus subsequent booster-training group (G2), to the basic at-home SOPT group (G3), or to the basic attention-control group (G4). Basic training involves 10 hours of either the SOPT or attention-control training during the first 6 weeks of participation. Booster-training involves 4 additional hours of SOPT training at 11 months of participation.
