Understanding the effects of environmental change on natural ecosystems is a major challenge, particularly when multiple stressors interact to produce unexpected "ecological surprises" in the form of complex, nonadditive effects that can amplify or reduce their individual effects. Animals often respond behaviorally to environmental change, and multiple stressors can have both population-level a...

This study examined the main and interactive relations of stressors and coping related to severe acute respiratory syndrome (SARS) with Chinese college students' psychological adjustment (psychological symptoms, perceived general health, and life satisfaction) during the 2003 Beijing SARS epidemic. All the constructs were assessed by self-report in an anonymous survey during the final period of...

PURPOSE A high proportion of adolescents living in low-income households in the United States are overweight or obese, food insecure, or exposed to high levels of individual, maternal, and family stressors. The aim of this paper was to identify the associations of food insecurity and the aforementioned stressors with an adolescent's propensity to be overweight or obese. We hypothesized that ind...

OBJECTIVES : We examined the role that novelty plays in determining interactions between chronic and acute stress, when both the chronic and acute stressors emphasize emotional processing (i.e. stressful stimuli that do not present immediate threats to somatic homeostasis, and are processed primarily by limbic and forebrain circuits). METHODS : Rats were exposed to a chronic variable stress (CV...

Psychological stressors are social and physical environmental circumstances that challenge the adaptive capabilities and resources of an organism. These circumstances represent an extremely wide and varied array of different situations that possess both common and specific psychological and physical attributes. The challenge for theory, research, and practice is to abstract and understand the s...

Work stressors, conflict asymmetries and dissatisfaction with the status quo are all negative factors which workers today are subjected to. Unfortunately, these situations occur more often than companies would want. However, negative results, despite what might be expected, do not always follow in the performances of affected employees. In this paper, through a theoretical review, it is shown u...
