Skin conductance data during go/no-go task

Skin conductance data recorded in 67 healthy subjects while they performed a go/no-go task. Most subjects performed 4 sessions of the task. Some have less than 4 due to loss of signal in one of the sessions. For details of the task, see paper: http://www.jneurosci.org/content/early/2019/06/12/JNEUROSCI.0508-19.2019.abstract <br>Briefly, the task contains approximately 2/3 go and 1/3 no-go trials. Correct go and no-go responses were rewarded and incorrect responses were punished with either a dollar or nickel. Thus, there are 8 conditions: 'GS_dollar','GS_nickel','GE_dollar','GE_nickel','NGS_dollar','NGS_nickel','NGE_dollar','NGE_nickel' where GS: go success, GE: go error, NGS: no-go successs, NGE: no-go error<br>Thus, for each subject, data for each condition and each session has been named accordingly. The data are organized by subject. Each subject has a folder which contain data for each session and each task condition. Within the task condition file, time series of skin conductance signal can be found for each trial.<br>Onsets (zipped file): onsets of each task condition. The data are organized by session. For each session, a 1x8 cell contains onsets for 8 conditions with the order as follows: 'GS_dollar','GS_nickel','GE_dollar','GE_nickel','NGS_dollar','NGS_nickel','NGE_dollar','NGE_nickel'<br>The data for the onsets are in MATAB format.<br>Skin conductance and onset data are in MATLAB format.<br>Behavioral: behavioral performance (accuracy rate and response time) and basic demographics.<br><br>All data have been de-identified. Information about age and gender for each subject may be found in the demographic text file.<br><br>Further info can be found in readme file.<br><br>Any questions may be directed to [e-mail].<br>

本数据集包含67名健康受试者在完成go/no-go任务(go/no-go task)时记录的皮肤电导率(skin conductance)数据。大部分受试者完成了4轮任务，部分受试者因某一轮任务出现信号丢失，有效任务轮数不足4轮。任务详情可参阅论文：http://www.jneurosci.org/content/early/2019/06/12/JNEUROSCI.0508-19.2019.abstract

简言之，该任务约包含2/3的go试次(go trial)与1/3的no-go试次(no-go trial)。正确的go与no-go反应可获得奖励，错误反应则会被处以1美元或5美分的惩罚。由此共划分出8种实验条件：'GS_dollar'、'GS_nickel'、'GE_dollar'、'GE_nickel'、'NGS_dollar'、'NGS_nickel'、'NGE_dollar'、'NGE_nickel'，其中GS为go成功(go success)，GE为go错误(go error)，NGS为no-go成功(no-go success)，NGE为no-go错误(no-go error)。

每位受试者的各实验条件及各任务轮次的数据均已按上述规则命名。数据按受试者进行组织，每位受试者对应一个专属文件夹，其中包含各任务轮次与各实验条件的数据。在单实验条件的数据文件中，可获取每一试次的皮肤电导率信号时间序列。

任务条件试次起始时刻（压缩文件）：各实验条件的试次起始时刻数据。数据按任务轮次组织，每一轮任务对应一个1×8细胞数组(cell array)，包含8种实验条件的试次起始时刻，顺序依次为：'GS_dollar'、'GS_nickel'、'GE_dollar'、'GE_nickel'、'NGS_dollar'、'NGS_nickel'、'NGE_dollar'、'NGE_nickel'。该部分数据采用MATLAB格式存储。

皮肤电导率数据与试次起始时刻数据均采用MATLAB格式存储。

行为数据：包含行为表现指标（正确率与反应时）及受试者基本人口学信息。

所有数据均已完成去标识化处理。每位受试者的年龄与性别信息可在人口学文本文件中查询获取。
