PsPM-SF: SCR, ECG, PPU and respiration measurements from a delay fear conditioning task with auditory CS (monophones/triads), performed during MRI scanning

This dataset includes skin conductance response (SCR), electrocardiogram (ECG), peripheral pulse unit (PPU) and respiration measurements for 20 healthy unmedicated participants (10 females and 10 males, age range: 19 - 35 years, mean age: 24.2 +/- 4.9) participating in a classical (Pavlovian) discriminant delay fear conditioning experiment with auditory CS, during MRI scanning. Also included are CS and US information, and ratings of CS after the experiment. Simple and complex CS were simple sine tones (4 s), and triads in root position or in first inversion, 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 first asked to report their subjective estimate of how likely they were to receive a shock after a given CS in the future, on a visual analogue scale of 0-100. Then they were asked to rate pairs of CS sounds with respect to which of the two stimuli they liked less. NOTE: In Staib et al. 2015, this dataset is denoted as SC1F本数据集收录了20名健康未服药参与者（10名女性、10名男性，年龄区间为19至35岁，平均年龄24.2±4.9岁）的皮肤电反应（skin conductance response, SCR）、心电图（electrocardiogram, ECG）、外周脉搏单位（peripheral pulse unit, PPU）及呼吸测量数据。上述参与者在MRI扫描过程中，参与了一项采用听觉条件刺激（conditioned stimulus, CS）的经典（巴甫洛夫式）辨别延迟恐惧条件反射实验。数据集同时收录了条件刺激与无条件刺激（unconditioned stimulus, US）的相关信息，以及实验结束后参与者对条件刺激的评分数据。简单与复杂条件刺激分别为时长4秒的纯正弦音，以及处于根音位置或第一转位的三和弦。无条件刺激（US）为通过恒流刺激器（Digitimer DS7A，Digitimer公司，英国韦林花园城）以针阴极/环形阳极配置施加于参与者优势前臂的方形电脉冲序列。恐惧条件反射任务完成后，参与者首先需在0至100的视觉模拟量表上，报告自己对“未来遭遇某一给定条件刺激后遭受电击的可能性”的主观评估值。随后参与者需对成对的条件刺激声音进行评分，选出二者中更不令自己喜欢的那一个。注意：在Staib等（2015）的研究中，本数据集被标注为SC1F。
