Feasibility and Acceptability of Home-based Computerised Cognitive Training After Cardiac Surgery

Participants will be registered for individual accounts to an online CCT program created by BrainHQ (Posit Science, San Francisco), that can be administered using their own computer or tablet. BrainHQ has been associated with improvements in memory, attention, and processing speed. The program will be customised to target domains thought to be deficient in the postoperative period and will include training in memory, attention, and processing speed. Specifically, the following six games have been selected: hear, hear (auditory memory and attention), to-do list training (working memory), divided attention (attention), target tracker (attention), double decision (useful field of view and visual processing speed), and eye for detail (visual processing speed and visual working memory). The exercises are adaptive, adjusting the application difficulty to the participants performance.
