PsPM-PCF3: Skin conductance, heart beat, respiration, and eyetracker recordings from a fear conditioning task with different reinforcement probabilities

This dataset contains skin conductance responses (SCR), heart beat time stamps from a pulse oxymeter (HB), respiration, pupil size (PSR), and gaze coordinates measurements for 31 healthy individuals (15 females) participating in a delay fear conditioning experiment with 3 CS and different reinforcement probabilities (20%, 50%, 80%). CSs were three differently coloured triangles. The US was a 0.5-s electric shock of 250 square pulses with a 10% duty cycle, delivered with a constant current stimulator on participants' dominant forearm through a pin-cathode/ring-anode configuration. SOA between the CS onset and the US was 6 s. The ITI was drawn on each trial uniformly as a random integer between 7 to 11 s.
