PsPM-PIT2: Physiological Measurements from Pavlovian-to-Instrumental Transfer Tasks

38 healthy participants (22 females, 16 males, aged 24.8 +/- 3.6 years) underwent a three-session experiment involving instrumental conditioning, fear conditioning, and a Pavlovian-to-instrumental transfer task. The dataset contains electrocardiogram (ECG), pupil size (PSR), respiration, and skin conductance (SCR) measurements across all sessions. It was contributed by Yanxia Xia from the University of Zurich.

Use Cases

• Modeling physiological arousal (SCR, ECG) during fear conditioning based on visual CS and electrical US stimuli.
• Analyzing pupil size (PSR) dynamics as an index of cognitive effort during instrumental Go/NoGo tasks.
• Investigating the transfer of conditioned fear responses to instrumental behavior based on colored background cues.
• Studying individual differences in psychophysiological responses across learning paradigms.

Strengths

• Includes data from 38 participants with reported age and sex demographics (22 females, 16 males).
• Contains multi-modal physiological time-series: ECG, pupil size (PSR), respiration, and SCR.
• Covers three distinct experimental sessions (instrumental, Pavlovian, transfer) on the same day.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
