“…Using a similar longitudinal experimental design (i.e., 6-week meditation workshops, daily reports of positive emotions) we found that a common genetic variant associated with oxytocin signaling predict the degree to which mid-aged participants reported positive affect in response to loving-kindness meditation (Isgett, Algoe, Boulton, Way, & Fredrickson, 2016). In another study (Van Cappellen, Way, Isgett, & Fredrickson, 2016), we found that dual-blind administration of exogenous oxytocin vs. a placebo increased mid-aged men's positive affective responses – assessed with both implicit and explicit measures – to an initial 20-minute introduction to meditation, with effects especially evident for meaningful and self-transcendent affective experiences, such as gratitude and awe (Van Cappellen, in press). Future work is needed to investigate whether the oxytocin system influences positive affective responses to health behaviors other than meditation.…”
