OBJECTIVES Exposure to psychosocial stressors often elicits increases in negative affect and blood pressure (BP). Rumination, or thinking about a stressor after it passes, is associated with delayed recovery. Given that older age is associated with greater BP reactivity to psychosocial stressors, rumination may be more detrimental to the recovery of older adults than younger adults. The current...

Although research has demonstrated a strong linkage betweenmeaning of life and positive emotion, few studies have examined this association in the context of acculturation. The purpose of this study was to investigate the predictive effects of meaning of life and acculturative stressor on positive affect in a sample of Chinese international students in Australia and Hong Kong, and to compare th...

The body is colonized by an enormous array of microbes that are collectively called the microbiota. During quiescent periods, microbial communities within the gut are relatively resistant to change. However, several factors that disrupt homeostasis can also significantly change gut microbial community structure. One factor that has been shown to change the composition of the gut microbiota is e...

While much research has focused on linking stressful experiences to emotional and biological reactions in laboratory settings, there is an emerging interest in extending these examinations to field studies of daily life. The current study examined day-to-day associations among naturally occurring daily stressors and salivary cortisol in a national sample of adults from the second wave of the Na...
