57 spider-fearful adults (18 to 40) from a Saarland University exposure-therapy RCT watched 16 one-minute spider clips and then rested for 5 minutes while a PLUX BITalino recorded ECG, skin conductance and chest respiration at 100 Hz. This is the open phobic-anxiety arousal set behind Ihmig 2020 (PLoS One) and the 2026 baseline-normalisation benchmark.
This project contains electrocardiogram, skin conductance and respiration as raw data (unfiltered, unprocessed) recorded from consented, spider-fearful individuals using the wearable BITalino biosignal measurement device (PLUX – Wireless Biosignals S.A., Lisbon, Portugal) with the sampling rate set to 100 Hz per channel having 10-bit resolution.
All subjects were introduced to the exposure procedure and rationale that is mainly based on the principles of the one-session exposure treatment. The main focus of this study was to investigate if the use of an HRV biofeedback intervention could be a promising therapeutic add-on to exposure therapy for specific phobias. Biosignals were collected at the Saarland University (Germany) from July 2017 to July 2018, and there are 57 subjects in total.
The dataset may support studies on mental health and psychophysiology related to other anxiety disorders, such as fear of flying, social phobia and posttraumatic stress disorder.
