Pleasantness and meaningfulness are sometimes seen as opposing pursuits. Yet past research has found that the pursuit of meaning often leads to pleasure. In four longitudinal studies-three observational, one experimental, ranging from 5 weeks to 18 months-we investigated an inverse process, whereby specific kinds of pleasant states can foster a sen...

Objective We explore the personality of counties as assessed through linguistic patterns on social media. Such studies were previously limited by the cost and feasibility of large-scale surveys; however, language-based computational models applied to large social media datasets now allow for large-scale personality assessment. Method We applied a...

Although behaviors such as handwashing, mask wearing, and social distancing are known to limit viral spread, early in the COVID-19 pandemic, many individuals in the United States did not adopt them. The positivity resonance theory of co-experienced positive affect (Fredrickson, 2016) holds that shared pleasant states that include the key features o...

Shared positive emotions involving caring and synchrony—termed “positivity resonance”—are associated with mental health (Major et al., 2018). We hypothesized that, during the COVID-19 pandemic, individual differences in trait resilience would be linked with better overall mental health in part because those higher in trait resilience experience mor...

Although simple behaviors such as handwashing, mask wearing and social distancing are known to limit viral spread, early in the COVID-19 pandemic, many individuals in the United States did not adopt them. The Positivity Resonance Theory of collective positive affect holds that shared pleasant states that include the key features of mutual care and...

Combinations of multiple meditation practices have been shown to reduce the attrition of telomeres, the protective caps of chromosomes (Carlson et al., 2015). Here, we probed the distinct effects on telomere length (TL) of mindfulness meditation (MM) and loving-kindness meditation (LKM). Midlife adults (N = 142) were randomized to be in a waitlist...

Positivity resonance is a type of interpersonal connection characterized by shared positivity, mutual care and concern, and behavioral and biological synchrony. Perceived positivity resonance is hypothesized to be associated with well-being. In three studies (N = 175, N = 120, N = 173), perceived positivity resonance was assessed at the trait level...

The broaden-and-build theory hypothesizes that positive emotions broaden attention and thought-action urges and in doing so build durable biopsychosocial resources over time which supports an upward spiral toward well-being. Substantiating this framework, evidence shows that positive emotions grow psychological resources such as resilience, leading...

Religious, spiritual, and mystical experiences (RSMEs) are often described as having a noetic quality, or the compelling sense that the experience feels “real.” In this exploratory, multimethod study, 701 participants completed questions about the subjective qualities of their RMSEs, reported the impact of their RSMEs on various life domains, and p...

Experiences of profound existential or spiritual significance can be triggered reliably through psychopharmacological means using psychedelic substances. However, little is known about the benefits of religious, spiritual, or mystical experiences (RSMEs) prompted by psychedelic substances, as compared with those that occur through other means. In t...

Mystical experiences are often described as “ineffable,” or beyond language. However, people readily speak about their mystical experiences if asked about them. How do people describe what is supposedly indescribable? In this study, we used quantitative linguistic analyses to interpret the writings of 777 participants (45.5% female, 51.0% male) who...
