    Breathing Biofeedback for Police Officers in a Stressful Virtual Environment: Challenges and Opportunities.Jan C. Brammer, Jacobien M. van Peer, Abele Michela, Marieke M. J. W. van Rooij, Robert Oostenveld, Floris Klumpers, Wendy Dorrestijn, Isabela Granic & Karin Roelofs - 2021 - Frontiers in Psychology 12.
    As part of the Dutch national science program “Professional Games for Professional Skills” we developed a stress-exposure biofeedback training in virtual reality for the Dutch police. We aim to reduce the acute negative impact of stress on performance, as well as long-term consequences for mental health by facilitating physiological stress regulation during a demanding decision task. Conventional biofeedback applications mainly train physiological regulation at rest. This might limit the transfer of the regulation skills to stressful situations. In contrast, we provide (...)

    Modeling the Dynamics of Risky Choice.Marieke M. J. W. van Rooij, Luis H. Favela, MaryLauren Malone & Michael J. Richardson - 2013 - Ecological Psychology 25:293-303.
    Individuals make decisions under uncertainty every day. Decisions are based on in- complete information concerning the potential outcome or the predicted likelihood with which events occur. In addition, individuals’ choices often deviate from the rational or mathematically objective solution. Accordingly, the dynamics of human decision making are difficult to capture using conventional, linear mathematical models. Here, we present data from a 2-choice task with variable risk between sure loss and risky loss to illustrate how a simple nonlinear dynamical system can (...)

    Deep-Breathing Biofeedback Trainability in a Virtual-Reality Action Game: A Single-Case Design Study With Police Trainers.Abele Michela, Jacobien M. van Peer, Jan C. Brammer, Anique Nies, Marieke M. J. W. van Rooij, Robert Oostenveld, Wendy Dorrestijn, Annika S. Smit, Karin Roelofs, Floris Klumpers & Isabela Granic - 2022 - Frontiers in Psychology 13.
    It is widely recognized that police performance may be hindered by psychophysiological state changes during acute stress. To address the need for awareness and control of these physiological changes, police academies in many countries have implemented Heart-Rate Variability biofeedback training. Despite these trainings now being widely delivered in classroom setups, they typically lack the arousing action context needed for successful transfer to the operational field, where officers must apply learned skills, particularly when stress levels rise. The study presented here aimed (...)

    A Dynamical Model of Risky Choice.Marieke M. J. W. van Rooij, Luis H. Favela, MaryLauren Malone & Michael J. Richardson - 2013 - Proceedings of the 35th Annual Conference of the Cognitive Science Society 35:1510-1515.
    Individuals make decisions under uncertainty every day based on incomplete information concerning the potential outcome of the choice or chance levels. The choices individuals make often deviate from the rational or mathematically objective solution. Accordingly, the dynamics of human decision-making are difficult to capture using conventional, linear mathematical models. Here, we present data from a two-choice task with variable risk between sure loss and risky loss to illustrate how a simple nonlinear dynamical system can be employed to capture the dynamics (...)
