Abstract For many years psychophysiologists have been interested in stimulus related changes in heart rate and blood pressure. To represent these evoked heart rate and blood pressure patterns, heart rate and blood pressure data have to be transformed into ...
Abstract Effects of maintaining an alert state on event-related brain potentials (ERPs) and evoked cardiovascular responses were examined in an auditory detection task. Subjects were instructed to detect a possible difference in frequency between two ...
Abstract The Polar Vantage XL heart rate monitor provides an ambulatory, inexpensive method of continuously measuring heart rate. To examine the validity of the Polar monitor for measuring heart rate during resting periods and while engaging in two ...
Abstract Control or control-belief is often viewed as being directly instrumental in facilitating active coping in aversive situations, and yet the empirical evidence for the effects of control is inconclusive. In this study we investigated the role of ...
Heart rate has been reported to increase during nausea and has therefore been used as an indicator of motion sickness. However, the relationship between heart rate and subjective ratings of motion sickness has received little attention, and the autonomic ...
Abstract The effects of physical training on autonomic response to acute stress are controversial. In this study, heart rate (HR) and skin conductance level (SCL) were continuously recorded in response to a mental stressor in a sample of elite athletes ...
Abstract The present study analyzes the variations of heart rate (HR) and systolic and diastolic blood pressure (SBP and DBP) during 60 h of total sleep deprivation (TSD). All variables were evaluated every 2 h in a resting condition, during the ...
Abstract This experiment studies the role of the conditioned response (CR) in explaining the unconditioned response (UR) diminution phenomenon in heart rate (HR) classical conditioning. In order to analyze the implication of the different CR components on ...
Abstract Compared to normals or low alexithymics, high alexithymic subjects show a modified psychophysiological reactivity under experimental stress. This study aims to differentiate these effects under different load conditions (mental vs. emotional load,...
This paper reports three studies on the application of ambulatory monitoring in air traffic control (ATC). The aim of the first study was to explore a set of psychophysiological measures with respect to ATC workload sensitivity and feasibility at the ...
Gender differences in cardiovascular variables in response to laboratory stressors have been described. In real situations, although occupational stress is considered one of the major causes of cardiovascular diseases, there are few studies that follow a ...
Several studies have revealed that women report stronger feelings of disgust than men (Gross & Levenson, 1995; Schienle, Schäfer, Stark, Walter, & Vaitl, 2005). However, the extent to which this gender difference also influences physiological disgust ...
We examined the effect of training state on cardiac autonomic control in a naturalistic setting. Twenty-four vigorous exercisers were compared to age- and sex-matched sedentary controls. The regular exercisers were subjected to a 6-week training program ...
Performance outcomes, such as the distance rowed or run, can be influenced by the type of attentional focus an individual adopts. The present study tested how attentional focus during a weight training exercise influenced a direct measure of performance ...
This study investigated the cardiac and electrophysiological responses to feedback in a time-estimation task in which feedback-validity was manipulated. Participants across a wide age range had to produce 1 s intervals followed by positive and negative ...
The present study sought to investigate peripheral physiological responses to the anticipation of explicitly and ambiguously cued emotional pictures. Emotionally positive and negative as well as neutral pictures were presented to 32 healthy subjects. At ...
Abstract. The present study examined physiological reactivity to emotional stimuli as a function of attachment style. Skin conductance responses (SCRs) and heart rate (HR) changes were simultaneously recorded while participants engaged in ...
Abstract. Experience sampling and psychophysiological ambulant assessment methods were employed to compare reactions to social stress using a laboratory stressor (The Trier Social Stress Test [TSST]) or a corresponding real-life condition (...
Abstract. Resting respiratory sinus arrhythmia (RSA) is related to individual differences in waking affective style and self-regulation. However, little is known about the stability of RSA between sleep/wake stages or the relations between ...
Abstract. Individual and shared goals can be achieved through social interpersonal interaction, cooperation and competition being two different yet similar strategies to reach such aims and objectives. Nevertheless, there is a gap in ...
