Pspm-Pubfe: Psychophysiological Responses in Auditory Fear Conditioning

22 healthy participants (7 males, 15 females, aged 26.4+/-5.2 years) underwent a Pavlovian discriminant delay fear conditioning task. The dataset includes pupil size, skin conductance, electrocardiogram, and respiration measurements, alongside conditioned and unconditioned stimulus information, keypress responses, and correctness. Data supports analysis of autonomic nervous system correlates of fear learning and memory.

Use Cases

• Modeling the relationship between pupil dilation (PSR) and stimulus anticipation during fear conditioning.
• Analyzing skin conductance response (SCR) as an index of arousal to auditory conditioned stimuli (CS).
• Investigating trial-by-trial keypress response times and correctness in relation to learned associations.
• Examining the synchrony of electrocardiogram (ECG) and respiration signals with the delivery of an electric unconditioned stimulus (US).

Strengths

• Includes multimodal physiological recordings (PSR, SCR, ECG, respiration) from 22 participants, enabling cross-measure analysis.
• Provides detailed trial structure parameters: stimulus onset asynchrony (SOA) of 3.5s and inter-trial intervals (ITI) of 7, 9, or 11s.
• Contains participant behavioral responses (keypress) and accuracy data, linking physiology to performance.

Limitations

• Key metadata such as row count, file size, specific column names, and last update date are unavailable across all sources.
• The dataset scale is limited to a single study with 22 participants, which may constrain generalizability.
• Documentation gaps exist regarding the exact data format and the total number of trials per participant.
