PsPM-trSP4: SCR measurement in response to face photographs withangry, neutral, and fearful expression while subjected to auditory distractors

This dataset includes skin conductance response (SCR) measurements for each of 42 healthy unmedicated participants (21 males and 21 females aged 25.2 +/- 4.0 years) in response to 38 face photographs (modified from the Karolinska Directed Emotional Faces set, KDEF), each presented once with angry, neutral, and fearful expression for 1 s each. Meanwhile, participants were listening to regular or random distractor sounds, as described in Bach et al. (2015). ITI was selected randomly on each trial from 7.5 s, 9.0 s, or 10.5 s (misprinted in the publications), plus a variable delay of around 0.1 s for image loading. The experiment was preceded by a 2-minute resting period and divided into 3 blocks, separated by resting periods. Each resting period begins and ends with an event marker in the SCR recordings.本数据集包含42名未服用药物的健康受试者（21名男性、21名女性，年龄为25.2±4.0岁）的皮肤电反应（skin conductance response, SCR）测量数据。受试者共观看38张面部照片（改编自卡罗林斯卡导向情绪面孔集（Karolinska Directed Emotional Faces set, KDEF）），每张照片分别以愤怒、中性、恐惧三种表情各呈现一次，单次呈现时长为1秒。实验过程中，受试者同时聆听规则或随机的干扰音，具体实验设计详见Bach等人2015年的研究。每轮试次的试间间隔（inter-trial interval, ITI）从7.5秒、9.0秒或10.5秒中随机选取（文献中存在印刷错误），此外还需加上约0.1秒的可变图像加载延迟。实验开始前设有2分钟的静息阶段，整个实验分为3个组块，组块之间设有静息阶段。每一段静息阶段的起始与结束，均会在皮肤电反应的记录中生成事件标记。
