New Citations | Physiological Measures to Understand Stress

BIOPAC provides software and hardware that allows research teams to study physiological measures related to stress. Here are a few notable studies using BIOPAC equipment for ECGEDA, and EEG/ERP.

Moms Moderating StressNeal E Johnson

Can relaxation techniques help lower stress on both mother and fetus? Using an MP36R Data Acquisition system to record ECG and EDA, this study was able to measure how each mother’s body reacted to music, guided imagery, or resting relaxing exercises. Were they able to mitigate potential negative effects of maternal stress? Read the full study: Acute relaxation during pregnancy leads to a reduction in maternal electrodermal activity and self-reported stress levels (Ilena Bauer, Julia Hartkopf, Anna-Karin Wikstrom, Nora K. Schaal, Hubert Preissl, Birgit Derntl, Franziska Schleger)

Green with Envious Stress Levels

If kids won’t eat their greens, could introducing more greens in video games help relieve stress? These researchers compared a natural video game setting against an urban video game setting while collecting wireless CG and EDA from a BioNomadix module. Would the participants be more or less stressed based on their virtual surroundings while interacting with the virtual worlds?

Wallace)

Too Hot to Think

Like hypothermia affects cognitive function from being too cold, could being too hot produce related results? By turning up the heat on participants in intervals while they completed Flanker tests and recording heart rate on a BIOPAC Data Acquisition system, these scientists were able to assess the effects of heat stress on cognitive function.

Projection VR, Training, Physiological Evaluation & Biofeedback

Projection-based virtual reality is a powerful immersive medium that makes it easy to experience VR applications without the need for heavy headgear or cables. With unobtrusive wireless sensing technology, researchers can easily measure their physiological and behavioral responses.

You Will Learn To:
• Understand key principles of combing virtual reality + physiological data recording
• Mark events from the simulation into the physiological record
• Access physiological data in the VR environment for biofeedback and control
• Set up a projection-based virtual reality simulation room
• Analyze the resulting data
