PsPM-FR: SCR, ECG and respiration measurements in a delay 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 for 31 healthy unmedicated participants (09 males and 23 females aged 23.32+/-3.61 years) participating in a classical (Pavlovian) discriminant delay fear conditioning task. CS were a red and a blue rectangle. 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 3.5 s. CS and US co-terminated. During extinction phase, an auditory startle probe (ST) was delivered 3.8 s after CS onset via headphones (100 dB, 50 ms duration with 2ms on- and offset ramp). 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（skin conductance response, SCR）、心电图（electrocardiogram, ECG）及呼吸测量数据，同时涵盖条件刺激（Conditioned Stimulus, CS）与非条件刺激（Unconditioned Stimulus, US）信息、按键反应及按键反应时，涉及31名未服药的健康参与者（其中男性9名、女性23名，年龄为23.32±3.61岁），所有参与者均参与了一项经典（巴甫洛夫式）判别延迟恐惧条件反射任务。本次任务中的条件刺激为红色矩形与蓝色矩形。非条件刺激为时长0.5秒的方形电脉冲，其脉冲时长0.2毫秒、频率为10Hz。条件刺激呈现与非条件刺激呈现之间的刺激呈现异步性（Stimulus Onset Asynchrony, SOA）为3.5秒，且条件刺激与非条件刺激同时终止。在消退阶段，通过头戴式耳机于条件刺激呈现后3.8秒呈现听觉惊吓探针（auditory startle probe, ST），该探针参数为100分贝、时长50毫秒，且带有2毫秒的升降沿斜坡。每一试次的试间歇期（Inter-Trial Interval, ITI）均随机设置为7秒、9秒或11秒。
