PsPM-LI: SCR, ECG, PSR and respiration measurements in a delay fear conditioning task with auditory CS and electrical US.

This dataset includes pupil size response (PSR), skin conductance response(SCR), electrocardiogram (ECG) and respiration measurements for each of 20 healthy unmedicated participants (8 males and 12 females aged 22.8+/-3.3 years) participating in a classical (Pavlovian) discriminant delay fear conditioning task. (One additional participant in the initial sample in Korn et al. (2017) - but who did not finish the experiment and was not included into the analysis - is not contained in this dataset.) The acquisition data is separated into two sessions which were recorded consecutively with a break of approximately 5 min. CS consist of two sine tones with constant frequency (220 Hz or 440 Hz, 50-ms onset and offset ramp) and last for 6.5 s. US is a 0.5 s 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. SOA betwen the CS and US is 6 s. The ITI is randomly determined on each trial to be 7, 9, or 11 s.

本数据集包含20名健康未用药参与者（8名男性、12名女性，年龄22.8±3.3岁）在经典（巴甫洛夫）判别式延迟恐惧条件反射任务中的瞳孔尺寸反应（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。初始样本中Korn等人（2017）的1名额外参与者因未完成实验且未纳入分析，未被包含于本数据集。采集数据分为两个连续录制的实验阶段，两阶段之间间隔约5分钟的休息时段。条件刺激（conditioned stimulus, CS）为两种恒定频率的正弦音调（220 Hz或440 Hz，起止斜坡时长50 ms），持续时长6.5 s。非条件刺激（unconditioned stimulus, US）为时长0.5 s的方形电脉冲序列，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。条件刺激与非条件刺激的刺激起始异步时间（stimulus onset asynchrony, SOA）为6 s。每一试次的试间间隔（inter-trial interval, ITI）随机设置为7、9或11 s。
