Elevated neuroticism is associated with increased psychological reactivity to stressors. Research on individual differences and physiological reactivity (e.g., electrodermal activity), however, has focused on clinical samples and measures of basal activity (e.g., nonspecific skin conductance responses) or responses to nonaffective stimuli. Surprisingly, there is a dearth of work on physiologica...

There is increasing interest in developing means to estimate, in real-time, the level of stress of computer users, particularly for applications such as computer-based tutoring. This real-time stress recognition has been attempted through the processing of a variety of biosignals measured from the computer user, such as the Galvanic Skin Response (GSR), the Blood Volume Pulse (BVP), etc. Recent...

In this paper, a pilot study on the relationship between significant information, presence and stress in virtual environments is presented. The experiment shown in this work was performed with a Medical Emergency Training Simulator based on virtual reality, and was conducted with two sets of subjects: critical care specialists and people without experience in medicine, trained to properly act w...

Negative amplitude shifts of cortical potential are related to seizure activity in epilepsy. Regulation of the cortical potential with biofeedback has been successfully used to reduce the frequency of some patients' seizures. Although such behavioural treatments are increasingly popular as an alternative to pharmacotherapy, there has been no investigation of the mechanisms that might bridge the...

Anxiety disorders are the most common reasons for referring to specialized clinics. If the response to stress changed, anxiety can be greatly controlled. The most obvious effect of stress occurs on circulatory system especially through sweating. the electrical conductivity of skin or in other words Galvanic Skin Response (GSR) which is dependent on stress level is used; beside this parameter pe...

This article studies the development and implementation of different electronic devices for measuring signals during stress situations, specifically in academic contexts a student group Engineering Department at University Pamplona (Colombia). For research’s development, physiological were used through Galvanic Skin Response (GSR), electrical response heart by using an electrocardiogram (ECG), ...

The present study aimed at comparing the efficacy of two relaxation techniques on stressed females.30 highly stressed female subjects were selected and randomly assigned to three groups (N=10 each) (a) group 1 receiving galvanic skin resistance biofeedback, (b) group 2 receiving progressive muscle relaxation training, (c) group 3 control. The stress level was determined using Comprehensive Anxi...

Nutritional and dietary interventions and the introduction of novel food products and ingredients require a thorough understanding of the drivers of food choice, which are embedded in local context and culture. We developed a framework of "gastronomic systems research" (GSR) to understand culture-specific consumer food choice, and contextualise it to a target population of urban, middle- to hig...
