From a young age, children are concerned about social status. Status indicates children's position within a social hierarchy (Anderson et al., 2015) and is often reflected in their popularity (i.e., social visibility, importance, and influence; Lease et al., 2002).

We hypothesized that children with higher narcissism levels would show intensified positive and negative affective responsiveness to status gains and losses, and that so would their parents. We tested this idea in a randomized experiment, using facial electromyography (fEMG) to track
