Electrodermal and cardiovascular activity in psychopathy : indicants of a coping response
The most well accepted theory of pscyhopathy, and the one which has spawned the largest amount of research, was developed by Cleckley (1976). Recently, Hare (1980a, 1985b) created the Psychopathy Checklist based upon 16 characteristics of psychopathy elaborated by Cleckley. The checklist is a valid …

Cardiovascular Activity During Laboratory Tasks in Individuals with High and Low Worry
… and worry have been related to exaggerated cardiovascular reactivity and delayed recovery to laboratory stressors, and to increased risk of cardiovascular disease. This study examined cardiovascular responses in high and low worriers to a range of laboratory tasks. The aim of this study was …

Anger Induction and Ambient Interventions: Effects on Cardiovascular Activity and Frontal EEG Asymmetry
… and aims: The experience of anger could affect cardiovascular (CV) and electro-encephalographic (EEG) parameters but such parameters could vary within the motivational context. Although models of motivational contexts were proposed by CV literature as challenge/threat (Blascovich & Tomaka, 1996) …

Cognitive functioning, cardiovascular activity, and state affect in men with and without a parental history of hypertension
… of hypertension (PH+ and PH-, respectively). Cardiovascular and state affect responses at rest and during testing were examined in order to determine whether they can account for any parental history group differences in cognitive functioning. PH+ participants performed more poorly on Block …

Exploring the Cardiovascular Response to Anger Imagery and Speech in Vietnam Veterans With and Without Posttraumatic Stress Disorder
… The current study explored the patterns of cardiovascular responding associated with varying anger induction methods, specifically personal anger memory recall through verbalization versus imagery in a sample of Vietnam combat veterans with and without Posttraumatic Stress Disorder (PTSD). …

The impact of spinal stabilization exercises on pain, disability, and physical functional after lumbar spinal fusion
… prefer a rehabilitative program that includes cardiovascular activity, trunk stabilization exercises performed with the lumbar spine in a neutral position, and reinforcement of body mechanics. Next, five low-load, neutral spine stabilization exercises were tested with ultrasound imaging. Two …

Central Cardiovascular Effects of Arginine Vasopressin in the Lateral Habenular Region in Anesthetized Rats
… no change from basal values. The increased cardiovascular activity elicited by central administration of arginine vasopressin suggests that vasopressin acts within the lateral habenular region to exert a central cardiovascular effect.

Measuring Self-Reported Exercise, Motivation to Exercise, and Sexism in Women
… of gender-related stereotypes about physical activity. A sample of 79 females completed an online survey that included questions about demographic characteristics, primary exercise type (i.e., cardiovascular exercise, weight-lifting, or hobbies), average number hours spent engaging in their …

Do Social Control Motives Combine with Perceptions of Social Support to Predict Relationships between Interpersonal Stress and Blood Pressure in the Normal Environment?
<p>Social support is related to lower risk for cardiovascular disease development. Yet, research has failed to yield consistent evidence for psychological mechanisms of relationships between social support and health outcomes. Explanations for these failures include limitations of research design …

Thinking Caps and Running Laps: Exploring the Importance of Physical Activity and Cognitive Development
… articles related to the impact physical activity has on cognitive development. I attended a conference where I heard from experts about the positive impact physical activity has on the brain. Many elementary and secondary schools are cutting physical education courses in exchange for …

Analysis of Quantitative Electroencephalographic and Cardiovascular Responses to Stress Amoung Low- and High-Hostiles
… to identify higher cortical correlates of cardiovascular arousal. Low- and high-hostile, right-handed, undergraduate men were identified using the Cook Medley Hostility Scale (CMHS). All participants (N = 30) completed the cold pressor paradigm. Cardiovascular (heart rate, systolic blood …

Altered GABA ergic system in the posterior hypothalamus of the spontaneously hypertensive rat
… hypothalamus (PH) contributes to modulating cardiovascular activity. Blockade of GABA receptors on neurons in this area elicits an increase in sympathetic discharge, arterial pressure and heart rate. It has been proposed that a deficit in this inhibitory system may be responsible for the …

Efeito do relaxamento induzido por diosgenina em artéria mesentérica de rato após administração de 17-β estradiol.
Cardiovascular disease is a major cause of morbidity and mortality in post - menopausal women, estrogen depletion in particular 17 - β estradiol a conditioning factor.Currently researchers have attempted, in studies with phytoestrogens, an alternative to impro ve the treatment of this illness, …

Investigation into the Vasomotor Signs and Symptoms of the Menopause
… in plasma and whole blood pharmacological activity were examined in post-menopausal women, at rest and during a hot flush, and in a group of pre-menopausal controls, at rest and during heat induced vasodilatation. The hot flush was found to be associated with an altered cardiovascular …

Graded Cerebral Activation to Noise: Behavioral and Cardiovascular Effects
… namely, that increasing magnitude of cerebral activity within the right anterior temporal region generates increasing levels of sympathetic control of heart rate and blood pressure and that the right lateral frontal region acts to inhibit sympathetic activity. A total of 45 right handed men, …

Women’s embodied experiences of exercise (sub)cultures: communities of practice in the CrossFit box
CrossFit is a popular leisure activity for women, which is unusual given its similarities to predominantly male dominated strength and resistance-based activities. Traditionally women have been drawn more towards cardiovascular activity, shying away from resistance and weight-bearing activities …

Cortical and autonomic modulation of attentional control /
… are thought to exert modulatory control over cardiovascular arousal. Therefore, ACC is not only responsible for the implementation of cognitive control, but also for the dynamic regulation of cardiovascular activity that characterizes healthy heart rate and adaptive behaviour. However, …

In-ear Audio For Physiological Monitoring
… audio. We use physiological couplings between cardiovascular activity, gait, and respiration to indirectly estimate respiratory rate from heart sounds and footstep sounds captured by the in-ear microphone. In doing so, we effectively overcome the shortcomings of requiring reliable respiratory …

Information Processing for Biological Signals: Application to Laser Doppler Vibrometry
Signals associated with biological activity in the human body can be of great value in clinical and security applications. Since direct measurements of critical biological activity are often difficult to acquire noninvasively, many biological signals are measured from the surface of the skin. This …

EFFECTS OF ACUTE NORMOBARIC HYPOXIA DURING EXERCISE AND CONCURRENT MENTAL STRESS ON THE CARDIOVASCULAR SYSTEM IN HEALTHY ATHLETES
… as physiological stressors that challenge cardiovascular homeostasis through mechanisms orchestrated by medullary cardiovascular control centers. During physical exertion, the activation of the “exercise pressor reflex” facilitates systemic adjustments to preserve perfusion of vital organs …
