PsPM-VIS: Physiological and Eye-Tracking Data from a Fear Conditioning Task

A dataset from the University of Zurich contains physiological and eye-tracking measurements from 29 healthy participants during a Pavlovian fear conditioning experiment. The experiment involved three blocks: two fear acquisition phases and one extinction phase, with randomized trial orders. Data includes skin conductance responses, electrocardiogram, respiration, pupil size, and gaze coordinates recorded during the task.

Use Cases

• Modeling skin conductance response dynamics based on conditioned stimulus presentations.
• Analyzing heart rate variability from ECG data during fear acquisition and extinction trials.
• Studying pupil size and gaze patterns in relation to visual fractal stimuli and threat anticipation.
• Investigating the synchrony between respiration, SCR, and cardiac activity during a discriminant delay fear conditioning paradigm.

Strengths

• Includes data from 29 participants with reported demographics (17 females, 12 males, aged 25.3 +/- 3.7).
• Contains five synchronized physiological and eye-tracking measurement modalities: SCR, ECG, respiration, pupil size, and gaze coordinates.
• Experimental design is detailed, specifying trial counts (e.g., 15 CS+US+, 15 CS+US-, 30 CS- per acquisition block) and timing parameters like SOA and ITI.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
