Abstract: ObjectivesThe ability to produce situation-appropriate cognitive and emotional responses is dependent on autonomic nervous system (ANS) functionality. Heart rate variability (HRV) is an index of ANS functionality, and resting HRV levels have been associated with cognitive control and inhibitory capacity in young adults, particularly when faced with emotional information. As older adults’ greater preference for positive and avoidance of negative stimuli (positivity effect) is thought to be dependent on cognitive control, we hypothesized that HRV could predict positivity-effect magnitude in older adults.MethodWe measured resting-level HRV and gaze preference for happy and angry (relative to neutral) faces in 63 young and 62 older adults.ResultsWhereas young adults showed no consistent preference for happy or angry faces, older adults showed the expected positivity effect, which predominantly manifested as negativity avoidance rather than positivity preference. Crucially, older but not young adults showed an association between HRV and gaze preference, with higher levels of HRV being specifically associated with stronger negativity avoidance.DiscussionThis is the first study to demonstrate a link between older adults’ ANS functionality and their avoidance of negative information. Increasing the efficiency of the cardiovascular system might selectively improve older adults’ ability to disregard negative influences.
