PsPM-FER02: Physiological Time-Series from a Fear Return Study

PsPM-FER02 contains multimodal physiological time-series data from 71-74 healthy participants in a repeated-measures fear conditioning experiment. The dataset includes pupil size response, skin conductance response, electrocardiogram, respiration, conditioned stimulus information, and participant keypress responses. It was designed to assess the return of fear across three experimental conditions and three sessions.

Use Cases

• Modeling the relationship between conditioned stimuli and physiological arousal based on skin conductance and pupil size responses.
• Analyzing temporal dynamics of fear responses using synchronized electrocardiogram, respiration, and stimulus timing data.
• Investigating individual differences in fear extinction and return using keypress correctness and shock expectancy ratings.
• Developing signal processing methods for cleaning and analyzing concurrent pupil size, skin conductance, electrocardiogram, and respiration recordings.

Strengths

• Includes synchronized, high-frequency physiological measurements from four modalities (PSR, SCR, ECG, respiration) for each trial.
• Data originates from a controlled, repeated-measures experimental design with 71-74 participants, providing a basis for within-subject comparisons.
• Dataset is annotated with precise experimental parameters, including stimulus onset asynchrony (3.5s), inter-trial interval (7-11s), and stimulus characteristics.

Limitations

• Conflict in reported participant count: two sources state 71 participants (33M/38F), while one states 74 participants (33M/41F).
• Key metadata is missing, including specific column names, file formats, dataset size, and the exact date of last update.
• The dataset's scale is limited to a single laboratory study, which may affect generalizability.
