PsPM-TC: SCR, ECG, EMG and respiration measurements in a discriminant trace fear conditioning task with visual CS and electrical US.

This dataset includes skin conductance response (SCR), electrocardiogram (ECG) and respiration measurements. Also included are CS and US information, keypress responses and keypress response times from 18 healthy unmedicated participants (8 males and 10 females aged 23.89+/-2.52 years) participating in a classical (Pavlovian) discriminant trace fear conditioning task. CS were a red and a blue rectangle presented for 3 seconds. US consisted of 0.5 s square electric pulses with 0.2 ms duration and 10 Hz frequency. SOA between the CS onset and US was 4 s. The ITI was randomly determined on each trial to be 7, 9, or 11 s.本数据集包含皮肤电反应（SCR）、心电图（ECG）与呼吸测量数据，同时收录了参与经典（巴甫洛夫式）鉴别痕迹恐惧条件反射任务的18名健康且未服用药物的参与者的条件刺激（CS）、非条件刺激（US）信息、按键反应及按键反应时数据。该批参与者年龄为23.89±2.52岁，其中男性8名、女性10名。条件刺激为红色与蓝色矩形，单次呈现时长为3秒。非条件刺激由时长0.2毫秒、频率10Hz的方波电脉冲组成，总呈现时长为0.5秒。条件刺激起始与非条件刺激之间的刺激呈现间隔（SOA）为4秒。每个试次的试间间隔（ITI）随机取值为7秒、9秒或11秒。
