CFG1: SCR, ECG, respiration, startle eyeblink EMG, and eyetracking measurements in a contextual fear conditioning task with 5 static room images with acquisition and recall test after one week

This dataset contains skin conductance responses (SCR), electrocardyogram (ECG), respiration, electromygram (EMG), pupil size (PSR), and gaze coordinates measurements for 29 healthy unmedicated participants (18 females and 11 males aged 23 +/- 2.7) participating in a Pavlovian differential contextual fear conditioning experiment with 2 sessions. CSs were five static room images presented full-screen, one of which served as CS+, coupled with US, and the other four as CS-. US was a train of 250 square electric pulses with 0.2 ms duration with a duty cycle of 10%, delivered with a constant current stimulator on participants' dominant forearm through a pin-cathod/ring-anode configuration. SOA between the CS onset and US was 7.0 s. Participants underwent the conditioning task with CSs (CS+ 83% reinforced) and US delivery in session 1 with 4 blocks, and were tested in a retention/extinction task one week later in session 2 with 4 blocks, with CS and auditory startle probe (ST) delivered 7.0 s after CS onset via headphones (ca. 102 dB, 20 ms duration). No US was delivered during session 2. The ITI was jittered on each trial uniformly at random between 7.5 to 10.5 s. The blocks in each session were recorded on the same day with self-paced breaks.
