Perceived social-evaluative threat triggers the hypothalamic-pituitary adrenal (HPA) axis, resulting in cortisol release. The current study examined the effects of varying the levels of social-evaluative threat on the stress response. Sixty healthy men (mean age + 23.17 +/- 3.89 years) underwent a public speaking task. Four conditions were established on the basis of panel location (inside or outside the room) and number of panelists (one or two). It was hypothesized that these variations affect salivary cortisol and physiological responses in a gradient manner. The task elicited significant cortisol and blood pressure changes for all conditions, but no difference between the groups was found, suggesting that all conditions were equally stressful. Study conclusions were that, for men, the visual presence of a panel is not necessary to elicit a cortisol response. Furthermore, increasing the number of judges does not increase the intensity of the stress response in a gradual manner, but rather seems to follow a threshold pattern. Future studies should include women and try to define the possible threshold to activate the HPA axis.

Emotion-focused coping strategies during LGB sexual identity development are associated with current indices of biopsychosocial stress.

Few conceptual frameworks attempt to connect disaster‐associated environmental injuries to impacts on ecosystem services (the benefits humans derive from nature) and thence to both psychological and physiological human health effects. To our knowledge, this study is one of the first, if not the first, to develop a detailed conceptual model of how degraded ecosystem services affect cumulative stress impacts on the health of individual humans and communities. Our comprehensive Disaster‐Pressure State‐Ecosystem Services‐Response‐Health model demonstrates that oil spills, hurricanes, and other disasters can change key ecosystem components resulting in reductions in individual and multiple ecosystem services that support people's livelihoods, health, and way of life. Further, the model elucidates how damage to ecosystem services produces acute, chronic, and cumulative stress in humans which increases risk of adverse psychological and physiological health outcomes. While developed and initially applied within the context of the Gulf of Mexico, it should work equally well in other geographies and for many disasters that cause impairment of ecosystem services. Use of this new tool will improve planning for responses to future disasters and help society more fully account for the costs and benefits of potential management responses. The model also can be used to help direct investments in improving response capabilities of the public health community, biomedical researchers, and environmental scientists. Finally, the model illustrates why the broad range of potential human health effects of disasters should receive equal attention to that accorded environmental damages in assessing restoration and recovery costs and time frames.
