title: Subjective social status moderates cortisol responses to social threat.
abstract: Research has demonstrated a robust relationship between social status, physiology and health in humans and animals. However, perceptions of social status within a specific social group have rarely been studied in this area and may provide additional relevant information. The current investigation examines subjective perceptions of social status as a moderator of cognitive, emotional and cortisol responses to stressor tasks characterized by social-evaluative threat or its absence. As part of a larger study, 81 college students living in a residential dormitory completed a measure of their subjective perceptions of their social status within their dormitory floor. They were randomly assigned to undergo a standard performance stressor task either with or without social evaluation. It was hypothesized that individuals who perceived that they were of low status within their dorm group would show greater increases in negative self-evaluative emotions (i.e., shame) and cognitions (low social self-esteem) and greater cortisol responses to the stressor under conditions of social-evaluative threat. Subjective social status moderated cortisol responses to the social-evaluative stressor, but in a direction opposite that hypothesized. Individuals who perceived themselves to be of high status showed sizable and significant cortisol increases (both peak and recovery), while those who perceived themselves to be of low status did not mount a significant cortisol response to the stressor. Both groups showed increased negative self-evaluative responses to the tasks. A discussion of the possible health implications of the robust cortisol responses of high status individuals and the hyporesponsive cortisol reactions of low status individuals is provided.
