Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will compare the effect of broad and directed (narrow) technology-based training on basic perceptual and cognitive abilities in older adults and on the performance of simulated tasks of daily living including driving and fraud avoidance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will be randomly assigned to four training conditions: broad training using either 1) Posit Science's web-based "BrainHQ" or 2) the video game Rise of Nations, or to directed training for 3) Instrumental Activities of Daily Living (IADL) training on both driving, American Association of Retired Persons (AARP)'s web-based older driver training program, and training for fraud avoidance, a web-based tutorial on finance and fraud, or 4) to an active control condition of puzzle solving. Training will take approximately 15-20 hr for each treatment condition. Before training begins, participants will take baseline ability tests of perception, attention, memory, and cognition, activities of daily living, as well as a driving simulator test for hazard perception, and a financial fraud recognition test. They will be tested again on these measures following training completion, and at a one-year follow-up from training completion.

BrainHQ

Participants will be provided with a laptop computer and enrolled in a commercial web-based cognitive training program, BrainHQ, trained on how to access it, and instructed to complete a fixed number of sessions in 20 hours.

Rise of Nations

Participants will be provided with a laptop computer with the Rise of Nations video game, be trained in game play, and instructed to play the game for 20 hours

IADL training

Participants will be enrolled in American Association of Retired Persons' web-based driver training course, trained on how to access it, and asked to complete the course, estimated to take approximately 6-8 hours. They will also be provided with web-based access to a finance and fraud avoidance training tutorial, instructed on how to access it, and be asked to complete the course, estimated to take approximately 5-7 hours. The two courses combined are estimated to take about 15 hours.
