Inverse association between stress induced cortisol elevations and negative emotional reactivity to stress in humans.
Greater cortisol reactivity to stress is often assumed to lead to heightened negative affective reactivity to stress. Conversely, a growing body of evidence demonstrates mood-protective effects of cortisol elevations in the context of acute stress. We administered a laboratory-based stressor, the Trier Social Stress Test (TSST), and measured cortisol and emotional reactivity in 68 adults (48 women) between the ages of 25 and 65. In accordance with our pre-registered hypothesis (https://osf.io/t8r3w) and prior research, negative affective reactivity was inversely related to cortisol reactivity assessed immediately after the stressor. We found that greater cortisol response to acute stress is associated with smaller increases in negative affect, consistent with mood-protective effects of cortisol elevations in response to acute stress.
期刊介绍:
The journal Stress aims to provide scientists involved in stress research with the possibility of reading a more integrated view of the field. Peer reviewed papers, invited reviews and short communications will deal with interdisciplinary aspects of stress in terms of: the mechanisms of stressful stimulation, including within and between individuals; the physiological and behavioural responses to stress, and their regulation, in both the short and long term; adaptive mechanisms, coping strategies and the pathological consequences of stress.
Stress will publish the latest developments in physiology, neurobiology, molecular biology, genetics research, immunology, and behavioural studies as they impact on the understanding of stress and its adverse consequences and their amelioration.
Specific approaches may include transgenic/knockout animals, developmental/programming studies, electrophysiology, histochemistry, neurochemistry, neuropharmacology, neuroanatomy, neuroimaging, endocrinology, autonomic physiology, immunology, chronic pain, ethological and other behavioural studies and clinical measures.
