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本数据集包含20名健康未服药参与者的皮肤电反应（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。参与者信息为：10名女性、10名男性，年龄范围19~35岁，平均年龄24.2±4.9。他们参与了一项基于听觉条件刺激（conditioned stimulus, CS）的经典（巴甫洛夫式，Pavlovian）辨别延迟恐惧条件反射实验，实验全程在磁共振成像（Magnetic Resonance Imaging, MRI）扫描中进行。 数据集同时包含条件刺激（CS）与非条件刺激（unconditioned stimulus, US）相关信息，以及实验后对CS的评分数据。其中简单与复杂CS分别为时长4秒的纯正弦音，以及根位或第一转位的三和弦。US为通过恒流刺激器（Digitimer DS7A，Digitimer公司，英国韦林花园城），采用针阴极/环形阳极配置，在参与者优势前臂上递送的方形电脉冲串。 恐惧条件反射任务结束后，参与者首先需在0~100的视觉模拟量表上，报告未来在给定CS后收到电击的主观可能性估计值；随后需对成对的CS声音进行评分，选出二者中更不喜欢的刺激。 注：在Staib等人2015年的研究中，该数据集被标注为SC1F。
