Do inflammation and relational motivation coordinate having better sex? The interplay between C-reactive protein and relational approach motivation on sexual well-being.

Much evidence on heightened inflammation and social behavior focuses on social withdrawal. Building on recent theory (Muscatell and Inagaki, 2021), we focused instead on the socially affiliative experience of sex. We investigated the interplay between immunology and motivation on sexual well-being among 158 individuals in romantic relationships.

Everyday co-presence with a romantic partner is associated with lower C-reactive protein.

Social relationships are an important driver of health, and inflammation has been proposed as a key neurobiological mechanism to explain this effect. Behavioral researchers have focused on social relationship quality to further explain the association, yet recent research indicates that relationship quality may not be as robust a predictor as previously thought. Here, building on animal models of social bonds and recent theory on close relationships, we instead investigated merely being in the physical presence of one's romantic partner.

A new perspective on the social functions of emotions: Gratitude and the witnessing effect.

We propose a novel theoretical and empirical approach to studying group-level social functions of emotions and use it to make new predictions about social consequences of gratitude. Here, we document the : In social groups, emotional expressions are often observed by third-party witnesses-family members, coworkers, friends, and neighbors. Emotional expressions coordinate group living by changing third-party witnesses' behavior toward first-party emotion expressers and toward second-party people to whom emotion is expressed.
