Brief Summary

Inhibitory control refers to the conscious and voluntary suppression of predominant responses when they are automatic, inappropriate, or incorrect. Inhibitory control plays a key role in self-regulation and self-control behaviors in many different areas of everyday life. During aging, their decline would impact executive functioning and mental health. Recently, physiological training methods including heart rate variability biofeedback (HRV-BF), based on heart rate and respiration measurements, and hemoencephalography biofeedback (nirHEG NF), based on the hemodynamic response of some prefrontal regions, have proven to have a positive impact on executive functions. In this study, subjects of the experimental group were exposed to biofeedback training during 10 sessions, once a week, and their results compared to those of the control group, which did not receive biofeedback training. This study aims to explore the impact of training that combines two innovative techniques, such as heart rate variability biofeedback and hemoencephalography biofeedback on the inhibitory control of older adults. We expect positive effects of biofeedback training on the inhibition tasks and the targeted physiological parameters. Primary objective - We intend to demonstrate that heart rate variability biofeedback training coupled with hemoencephalography biofeedback training can be effective methods to counteract the decline of inhibitory control in older adults. Secondary objective - We intend to demonstrate that heart rate variability biofeedback and hemoencephalography biofeedback can effectively increase heart rate variability and blood flood oxygenation.

Study Arms (2)

BF Group

EXPERIMENTAL

Participants of the BF group are connected with a plethysmograph and a respiration belt in order to assess HRV indices. HRV-BF is principally given by means of a vertical bar graph dynamically varying in height and two graphic curves referring to the heart rate (in beats per minute) and physiological breathing pattern, (inspiration and expiration). Each nirHEG- BF session occurs after a ten-minute pause from the end of the HRV-BF training. nirHEG-BF is principally given by means of a vertical bar graph dynamically varying in height and represented on a computer monitor. The height of the change according to the hemodynamic response measured at each of the three prefrontal points (Fp1, Fpz, Fp2) To maintain motivation, the bar graph is associated with a game-like animation (puzzle) signaling successful regulation, e.g. by forwarding motion of the pieces of a puzzle.

Behavioral: Heart rate variability biofeedback; haemoncephalography biofeedback

No BF Group

NO INTERVENTION

The no BF group receive the same sensors and is exposed to the same environment of the BF group but real time biofeedback of physiological parameters (HRV and hemodynamic response) is deactivated so that participants can watch documentary videos without interruption.

Interventions

Ten 25-minute weekly heart rate variability biofeedback and 30 minute haemoencephalogrphy biofeedback sessions

BF Group
