Leadership is associated with lower levels of stress

As leaders ascend to more powerful positions in their groups, they face ever-increasing demands. As a result, there is a common perception that leaders have higher stress levels than nonleaders. However, if leaders also experience a heightened sense of control—a psychological factor known to have powerful stress-buffering effects—leadership should be associated with reduced stress levels. Using unique samples of real leaders, including military officers and government officials, we found that, compared with nonleaders, leaders had lower levels of the stress hormone cortisol and lower reports of anxiety (study 1). In study 2, leaders holding more powerful positions exhibited lower cortisol levels and less anxiety than leaders holding less powerful positions, a relationship explained significantly by their greater sense of control. Altogether, these findings reveal a clear relationship between leadership and stress, with leadership level being inversely related to stress.

Residential Mobility, Self-Concept, and Positive Affect in Social Interactions

The present research examined (a) the link between personal history of residential mobility and the self-concept and (b) the implications of such a link for positive affect in social interactions. Study 1 showed that the personal self was more central to the self-definition of frequent movers than to that of nonmovers, whereas the collective self was more central to the self-definition of nonmovers than to that of frequent movers. Results from a laboratory and a 2-week event sampling study (Studies 2 and 3) demonstrated that frequent movers felt happier when an interaction partner accurately perceived their personal selves, whereas nonmovers felt happier when a partner accurately perceived their collective selves. These findings present the first direct evidence on how personal history of residential mobility is linked to important individual differences in the self and positive affect in social interactions.

Cuteness and Disgust: The Humanizing and Dehumanizing Effects of Emotion

Moral emotions are evolved mechanisms that function in part to optimize social relationships. We discuss two moral emotions— disgust and the “cuteness response”—which modulate social-engagement motives in opposite directions, changing the degree to which the eliciting entity is imbued with mental states (i.e., mentalized). Disgust-inducing entities are hypo-mentalized (i.e., dehumanized); cute entities are hyper-mentalized (i.e., “humanized”). This view of cuteness—which challenges the prevailing view that cuteness is a releaser of parental instincts (Lorenz, 1950/1971)—explains (a) the broad range of affiliative behaviors elicited by cuteness, (b) the marketing of cuteness to children (by toy makers and animators) to elicit play, and (c) the apparent ease and frequency with which cute things are anthropomorphized.

The Faintest Speck of Dirt Disgust Enhances the Detection of Impurity

Purity is commonly regarded as being physically embodied in the color white, with even trivial deviations from whiteness indicating a loss of purity. In three studies, we explored the implications of this “white = pure” association for disgust, an emotion that motivates the detection and avoidance of impurities that threaten purity and cleanliness. We hypothesized that disgust tunes perception to prioritize the light end of the light-dark spectrum, which results in a relative hypersensitivity to changes in lightness in this range. In Studies 1 and 2, greater sensitivity to disgusting stimuli was associated with greater ability to make subtle gray-scale discriminations (e.g., detecting a faint gray stimulus against a white background) at the light end of the spectrum relative to ability to make subtle gray-scale discriminations at the dark end of the spectrum. In Study 3, after viewing disgusting images, disgust-sensitive individuals demonstrated a heightened ability to detect deviations from white. These findings suggest that disgust not only motivates people to avoid impurities, but actually makes them better able to see them.

Residential Mobility, Personality, and Subjective and Physical Well-Being An Analysis of Cortisol Secretion

Frequent residential moves in childhood may be stressful. Because introverts find making new friends in a new town more difficult than extraverts, the authors predicted that residential moves would be more negatively associated with well-being among introverts than among extraverts. To test this hypothesis, the authors collected salivary cortisol samples from morning to evening for two consecutive days, in addition to self-reports of well-being. In general, the authors found support for this prediction among European American participants but not for African Americans or Asian Americans. Extraversion seems to buffer the stress of residential moves among European Americans, whereas it does not seem to play as important a role to this end among African and Asian Americans.
