PsPM-FER01: PSR, SCR, ECG and respiration measurements from a discriminant delay fear conditioning task with visual CS and electrical US.

This dataset includes pupil size response (PSR), skin conductance response (SCR), electrocardiogram (ECG) and respiration measurements. Also included are CS and US information and shock expectancy ratings at the end of the experiment for 30 healthy unmedicated participants (12 males and 18 females aged 23.9+/-4.4 years) participating in a classical (Pavlovian) discriminant delay fear conditioning task. Fear acquisition consisted of 10 CS- and 32 CS+ trials (16 CSa+/16 CSb+). Half of the CS+ trials were paired with an electric shock. CS were colored triangles (yellow/red/blue). US consisted of a 500 ms train of 250 square pulses with individual pulse width of 0.2 ms. SOA between the CS onset and US was 3.5 seconds. CS and US co-terminated. The ITI was randomly determined as discrete values between 7-11 seconds (mean 9 seconds).本数据集收录了30名健康未服药参与者（12名男性、18名女性，年龄23.9±4.4岁）在经典（巴甫洛夫）判别式延迟恐惧条件反射任务中的多模态生理数据与实验后评分，具体包括瞳孔大小反应（pupil size response, PSR）、皮肤电反应（skin conductance response, SCR）、心电图（electrocardiogram, ECG）及呼吸测量数据，同时还包含实验结束时采集的条件刺激（conditioned stimulus, CS）与无条件刺激（unconditioned stimulus, US）相关信息，以及电击预期评分。 该实验的恐惧习得阶段共包含10次CS-试次与32次CS+试次（其中16次为CSa+、16次为CSb+），半数CS+试次会与电击刺激配对呈现。CS为黄、红、蓝三色三角形；US为时长500ms的250次方波脉冲序列，单脉冲宽度为0.2ms。条件刺激起始时刻与US起始时刻的刺激起始异步间隔（stimulus onset asynchrony, SOA）为3.5秒，且CS与US同时终止。试次间间隔（inter-trial interval, ITI）随机取值为7至11秒的离散值，平均时长为9秒。
