ADHD Pupil Size Dataset

Data are organized in a panel data format, implemented as a Matlab (R) table array. Each row corresponds to a single trial of a single subject, and columns provide the distinct types of information available in any given trial. We have sorted the data in three main dimensions: 1) Trial information: this includes all information relevant to the trial: subject, group, trial number, cognitive load, and distractor type. 2) Behavioral data: here we placed the dependent variables we collected from the subject responses: Reaction time and performance. 3) Physiological data: here is the physiological dependent variable, pupil size during the trial.

本数据集采用面板数据格式进行组织，并以Matlab (R) 表格数组（table array）形式存储。每一行对应一名被试的单次实验试次（trial），每一列则代表单次试次中可获取的各类信息。我们从三大核心维度对数据进行了归类整理：1. 试次信息（trial information）：涵盖与单次试次相关的全部信息，包括被试、组别、试次序号、认知负荷（cognitive load）以及干扰项类型（distractor type）。2. 行为数据（behavioral data）：收录了通过被试反应采集得到的因变量，具体包括反应时（reaction time）与任务绩效（performance）。3. 生理数据（physiological data）：包含生理类因变量，即试次过程中的瞳孔直径（pupil size）。
