Testing the applicability of a virtual reality simulation platform for stress training of first responders

The current study explores whether different stressors in a virtual reality (VR) military training scenario cause increases in physiological stress. This would validate the use of VR simulation for stress training, as well as the physiological monitoring of trainees for educational purposes. Military cadets (n = 63) performed a patrol scenario ...

The role of emotion in self-explanations by cognitive agents

Artificial Intelligence (AI) systems, including intelligent agents, are becoming increasingly complex. Explainable AI (XAI) is the capability of these systems to explain their behaviour, in a for humans understandable manner. Cognitive agents, a type of intelligent agents, typically explain their actions with their beliefs and desires. However,...

Coping with acute stress in the military: The influence of coping style, coping self-efficacy and appraisal emotions

It is of utmost importance to better understand how professionals in high-risk organizations, such as the military and police, appraise and cope with acute stress situations. The goal of this two-wave study was to investigate the role of two individual characteristics, coping style and coping self-efficacy, for recruits' appraisal emotions and...

Coping with acute stress in the military: The influence of coping style, coping self-efficacy and appraisal emotions

It is of utmost importance to better understand how professionals in high-risk organizations, such as the military and police, appraise and cope with acute stress situations.

Effects of personal relevance and simulated darkness on the affective appraisal of a virtual environment

This study investigated whether personal relevance influences the affective appraisal of a desktop virtual environment (VE) in simulated darkness. In the real world, darkness often evokes thoughts of vulnerability, threat, and danger, and may automatically precipitate emotional responses consonant with those thoughts (fear of darkness). This...

Emotional responses to Multisensory Environmental Stimuli: A conceptual framework and literature review

How we perceive our environment affects the way we feel and behave. The impressions of our ambient environment are influenced by its entire spectrum of physical characteristics (e.g., luminosity, sound, scents, temperature) in a dynamic and interactive way. The ability to manipulate the sensory aspects of an environment such that people feel...

Work content influences on cognitive task load, emotional state and performance during a simulated 520-days' Mars mission

In high-risk domains such as human space flight, cognitive performances can be negatively affected by emotional responses to events and conditions in their working environment (e.g., isolation and health incidents). The COgnitive Performance and Error (COPE) model distinguishes effects of work content on cognitive task load and emotional state,...

De Individuele Werkprestatie Vragenlijst (IWPV): Interne consistentie, construct validiteit en normering

The Individual Work Performance Questionnaire (IWPQ): internal consistency, construct validity, and norm scores Measuring individual work performance, defined as “behaviors or actions of employees that are relevant to the goals of the organization”, is challenging. So far, there was no suitable questionnaire to measure individual work...

Hardiness and the response to stressful situations: Investigating mediating processes

The present study investigated mediating processes that explain how hardiness influences the way people respond to a stressful situation. Coping style and coping self-efficacy were investigated as mediating variables. Using a longitudinal design, hardiness, coping style and coping self-efficacy, and responses (i.e., appraisal and coping behavior...

Effects of third person perspective on affective appraisal and engagement: Findings from SECOND LIFE

This study investigates the influence of a first-person perspective (1PP) and a third-person perspective (3PP), respectively, on the affective appraisal and on the user engagement of a three-dimensional virtual environment in SECOND LIFE. Participants explored the environment while searching for five targets during a limited time span, using...

Cybersickness Influences the Affective Appraisal of a Virtual Environment

We investigated if cybersickness has an effect on the affective appraisal of a virtual environment (VE). For many applications it is essential that users experience the simulated environment in a similar way as the corresponding real one. Navigation through VEs is known to negatively influence the physical well-being of observers by inducing...

Thunderstorms in my computer: The effect of visual dynamics and sound in a 3D environment

We assessed the effects of the addition of dynamic visual elements and sounds to a levee patroller training game on the appraisal of the environment and weather conditions, the engagement of the users and their performance. Results show that the combination of visual dynamics and sounds best conveys the impression of severe weather conditions...

Engagement and EMG in serious gaming: Experimenting with sound and dynamics in the levee patroller training game

We measured the effects of sound and visual dynamic elements on user experience of a serious game, with special interest in engagement and arousal. Engagement was measured through questionnaires and arousal through the SAM and electromyography (EMG). We adopted the EMG of the corrugator (frown muscle) and the zygomatic muscle (smile muscle) as...

Cybersickness and desktop simulations: field of view effects and user experience

We used a desktop computer game environment to study the effect Field-of-View (FOV) on cybersickness. In particular, we examined the effect of differences between the internal FOV (iFOV, the FOV which the graphics generator is using to render its images) and the external FOV (eFOV, the FOV of the presented images as seen from the physical...

Strategies for successful evaluation and policy-making toward health care technology on the move: The case of medical lasers

Evaluating new health care technology that is rapidly diffusing is one of the greatest challenges to researchers and policy-makers. If no evaluation is done until the technology is mature, evaluation will not influence processes of diffusion. If evaluation is done early, it may be irrelevant when it is completed because of developments in the...
