OBJECTIVES Recent evidence suggests that younger and middle-age adults who show greater cardiovascular reactivity (CVR) to acute mental stress demonstrate better reasoning and memory skills. The purpose of this study was to examine whether older adults would exhibit a similar positive association between CVR and executive function and whether regular(More)
OBJECTIVES Poor sleep diminishes mental and physical health. The objective of this study was to examine associations between sleep disturbance and interleukin-6 (IL-6) responses to acute mental stress in older adults. DESIGN Observational study of community-dwelling, healthy older adults. SETTING Participants completed the study in a clinical research(More)
We examined 31 older couples' wife demand/husband withdraw communication patterns and cortisol responses to marital conflict. Regression analyses indicated that wife demand/husband withdraw sequences during conflict related to cortisol responses only for wives. Based on a mixed model that accounted for the interdependence of spouses' perceptions of(More)
OBJECTIVE To determine whether the relationship between interleukin (IL)-6 and depressive symptoms is moderated by participation in moderate-intensity physical activity in a sample of primary care patients. Elevated inflammation has been associated with a number of poor health outcomes. Depressive symptoms may be related to higher levels of the inflammatory(More)
This study examined how threat and coping appraisals and impression management opportunities influenced cardiovascular reactivity within a self-presentation context. Participants were videotaped performing a speech that they believed might be evaluated. Participants' physiological responses were recorded 1 week later while: (a) watching their speech,(More)
Introduction A growing body of research linking psychological and behavioral factors to the incidence and progression of cancer suggests that psychosocial factors may have an impact on some types of cancer [1–6]. In this paper, we suggest that it is through the impact these behavioral and psychological factors have on the cellular immune response, including(More)
This research was concerned with two issues: first, whether cardiovascular response patterns to a social stressor (i.e. self-presentation under evaluative circumstances) differ as a function of one's ability to control the impression one makes on others; second, whether cognitive appraisals are necessary or sufficient for the cardiovascular components of(More)
Allergic rhinitis (AR) is the fifth most common chronic disease, and the association between allergic disorders and anxiety is well-documented. To investigate how anxiety and stressors modulate skin prick test (SPT) responses and associated inflammatory responses, 28 men and women with AR were selected by clinical history and skin test responses. The(More)
OBJECTIVES To examine the cognitive and neural effects of vision-based speed-of-processing (VSOP) training in older adults with amnestic mild cognitive impairment (aMCI) and contrast those effects with an active control (mental leisure activities (MLA)). DESIGN Randomized single-blind controlled pilot trial. SETTING Academic medical center. (More)
