This dataset includes skin conductance response (SCR), electrocardiogram (ECG), peripheral pulse unit (PPU), respiration, pupil size response (PSR) and eyetracker measurements for 21 healthy unmedicated participants (11 females and 10 males, age range: 19 - 34 years, mean age: 25.5 +/- 4.1) participating in a classical (Pavlovian) discriminant delay fear conditioning experiment with visual CS, during MRI scanning. Also included are CS and US information, and ratings of CS after the experiment. Simple and complex CS were tilted Gabor patches, and plaids consisting of two overlaid Gabor patches, respectively. US was a train of electric square pulses delivered with a constant current stimulator (Digitimer DS7A, Digitimer, Welwyn Garden City, UK) on participants' dominant forearm through a pin-cathode/ring-anode configuration. After the fear conditioning task, participants were asked to rate pairs of CS patches with respect to which of the two stimuli they liked less. Then they were asked to report their subjective estimate of how likely they were to receive a shock after this CS in the future, on a visual analogue scale of 0-100.
