Four-Year Stability of Cardiovascular Reactivity to Psychological Stress

Journal of Behavioral Medicine, 1997
The 4-year stability of cardiovascular responses to laboratory psychological stress (mental arithmetic) was examined in 75 adults. The stability coefficients were .76 for heart rate (HR) change and .81 for absolute HR, .66 for systolic blood pressure (SBP) change and .52 for absolute SBP, .16 for diastolic blood pressure (DBP) change and .27 for ...

The Stress Response in Headache Sufferers: Physiological and Psychological Reactivity

Headache: The Journal of Head and Face Pain, 1997
When examining headache sufferers' reactivity to stress, few studies attend to differing characteristics of the environment. In this study, we evaluated the influence of the clarity/ambiguity and positive/negative valence of an event on subjects’ physiological and psychological reactivity.

Levels of craving influence psychological challenge and physiological reactivity

Appetite, 2015
Behavioural and cognitive pathways that lead to the activation and escalation of craving have been studied extensively. Conversely, limited efforts have been directed towards understanding how craving relates to motivational systems and neuroendocrine responses. These can be understood using the biopsychosocial model of challenge and threat.

Motor preparation aspects of cardiovascular reactivity to psychological challenge

International Journal of Psychophysiology, 1988
Neural control of the circulation has evolved in such a way that behavioral responses to psychological stress may be accompanied by a dramatic activation of the cardiovascular system. This study was designed to address the hypothesis that such instances of cardiovascular mobilization reflect a functional motor preparation response.

Extraversion is associated with lower cardiovascular reactivity to acute psychological stress

International Journal of Psychophysiology, 2023
Extraversion has been associated with positive physical health outcomes, with adaptive cardiovascular responses to stress being one potential physiological mechanism. The present study examined the influence of extraversion on both cardiovascular reactivity and cardiovascular habituation to an acute psychological stress task (Paced Auditory Serial ...

Reactivity to stress and psychological adjustment in adults with pituitary insufficiency

Clinical Endocrinology, 1992
OBJECTIVE Hypopituitary adults who were affected during childhood have a below‐average rate of marriage, a rate of unemployment that exceeds national norms, and often indicate dissatisfaction with their life circumstances. We undertook the present study to determine the effects of short stature versus those of pituitary hormone deficiency.DESIGN AND ...

Reactive cognition, reactive emotion: Toward a more psychologically-informed understanding of reactive homicide.

Psychology, Public Policy, and Law, 2008
Recent scholarship has drawn attention to the alternative contributions of dysfunctional reactive cognition (e.g., provocation interpretational bias) and emotion (e.g., provoked fury) in heat-of-passion killings. Two main theses have been advanced.

Vagal and cardiac reactivity to psychological stressors in trained and untrained men

Medicine & Science in Sports & Exercise, 2000
The aim of this study was to determine whether higher aerobic fitness is associated with enhanced vagal influences on the myocardium, resulting in moderation of chronotropic cardiac activity during psychological stress and recovery.Heart period (HP) and respiratory sinus arrhythmia (RSA) were obtained from 10 aerobically trained (AT) and 10 untrained ...

Discrimination Exposure, Neural Reactivity to Stress, and Psychological Distress

American Journal of Psychiatry
Discrimination exposure has a detrimental impact on mental health, increasing the risk of depression, anxiety, and posttraumatic stress. The impact discrimination exposure has on mental health is likely mediated by neural processes associated with emotion expression and regulation.
