**Background:** Subjective experience and physiological activity are fundamental components of emotion. There is an increasing interest in the link between experiential and physiological processes across different disciplines, e.g., psychology, economics, or computer science. However, the findings largely rely on sample sizes that have been modest at best (limiting the statistical power) and capture only some concurrent biosignals (e.g., making it problematic to seek specificity of some effects). We present a novel publicly available dataset of psychophysiological responses to positive and negative emotions that offers some improvement over other databases.
**Participants:** The database includsincludes 1157 participants cases (45% female) between the ages of 18 and 38 (*M* = 22.01, *SD* = 2.80).
**Emotions:** We experimentally elicited a wide range of positive and negative emotions, including amusement, anger, disgust, excitement, fear, gratitude, sadness, tenderness, and threat.
**Physiological Signals:** We measured the psychophysiological reactivity to emotional stimuli using ECG, ICG, EDA, Temp, Resp, SBP, DBP, CO, TPR signals. We also collected participants' valence and approach/avoidance motivation.
**Elicitation Methods:** In order to elicit emotions, we used pictures, film clips, speech preparation taks, and interpersonal communication task.
**Dataset Structure:** This directory contains a set of ZIP-compressed directories with a set of CSV files with psychophysiological information for particular participants, baselines, and emotions. We grouped the datafiles from all studies into a single folder sorted by emotions. This simplifies the usage of our dataset as the single set of emotion-related data that includes from 1157 cases. Name of each of these CSV files follows a consistent naming convention, i.e.: "S<study_id>_P<participant_id>_<phase_name>.csv”, where “S” stands for study, “P” for participants, and “<study_id>” & “<particpant_id>” are natural numbers indicating study and participant unique identifiers; and “<phase_name>” is the name of the phase of an experiment, e.g., ‘Baseline', 'Neutral8', 'Threat'. All psychophysiological signals recorded during the experiment for each individual are available in a study-related folders, i.e., single CSV datafile named “ S<study_id>_P<participant_id>_All.csv”. The description of all experimental-phase labels is explained in the metadata spreadsheet.
