Breathing, Relaxation, Attention Training, & Health in Older Adults (BREATHE)

The RFB protocol entails a combination of 8 weekly, in-lab training sessions using HRV biofeedback software (Physiocom, Seattle, WA) and daily paced breathing homework using a mobile-based HRV biofeedback app (Inner Balance, HeartMath, LLC, CA).

The investigators will use the INSIGHT online program (Posit Science). The platform will be built for our study, including 5 tasks (Eye for detail, Peripheral challenge, Visual sweep, Double decision, Target tracker) that practice different cognitive processes with PS/A as the shared domain.

Guided imagery relaxation, equal in dose and frequency to RF practice, will be used to control for relaxation effects that may occur via RFB (which could provide an alternative explanation for outcomes). IR activities will be facilitated using the Insight Timer mobile-based app, which emphasizes the use of visualization and imagery strategies to help the body relax.
