PsPM-SC4B: Physiological Responses in a Delay Fear Conditioning Task

Physiological measurements from 21 healthy participants during a Pavlovian discriminant delay fear conditioning task. The dataset includes pupil size response, skin conductance response, electrocardiogram, electromyogram, and respiration data, along with conditioned stimulus, unconditioned stimulus, and keypress information. It was contributed by Matthias Staib of the University of Zurich.

Use Cases

• Modeling the relationship between conditioned stimuli and physiological responses like skin conductance and pupil size.
• Analyzing individual differences in fear conditioning based on demographic data (10 males, 11 females).
• Studying temporal dynamics of physiological signals with precise inter-trial interval timings (7, 9, or 11 seconds).
• Classifying stimulus types (complex vs. simple auditory tones) based on multi-modal physiological recordings.

Strengths

• Includes multi-modal physiological data (SCR, ECG, EMG, PSR, respiration) for each trial.
• Data from 21 participants with reported demographics (average age 22.9 +/- 3.0 years).
• Stimulus parameters are precisely described (e.g., 68 dB, 0.5 s US duration, 3.5 s SOA).

Limitations

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