Data on electrophysiological responses and psychological reactions to 3D audio scenes and unpleasant International Affective Picture System images stimulation

The strong potential of three-dimensional (3D) audio to elicit sensory and cognitive responses suggests its possible integration into rehabilitation and palliative treatments, particularly for anxiety. However, the benefits of using 3D audio to address this emotional state are still emerging as a research area. This work presents data collected from an experiment designed to evaluate the effect of binaural 3D audio on emotional responses, and specifically anxiety. The dataset includes demographic information, psychological scores, electrophysiological signals, preprocessing codes, and the audiovisual media used during the study. Sixty healthy Mexican participants observed aversive images in random order to induce a transient state of anxiety. Subsequently, they listened to one of five audio scenes intended to modulate their emotional responses. Electrocardiographic and electrodermal activity were recorded throughout the experiment, and behavioral data were gathered using self-report questionnaires. This dataset could be reused to study the relationship between psychological and autonomic nervous system responses, and to explore the potential of spatial auditory stimulation for anxiety modulation and mental health applications.
