Raw_Data_SRTT_tDCS

A complex whole-body serial reaction time task was performed while participants received 20 minutes of transcranial direct current stimulation over either leg primary motor cortex (group = 4), bilateral dorsolateral prefrontal cortex (group = 1) or received sham stimulation (group = 3). SRTT learning was performed over two consecutive days with an inter-day interval of 24 hours. On day 1, 4 random sequences (R1-R4) were presented, followed by 15 learning sequences (S1-S15), followed by one random sequence (R5) at the end. On day 2, 1 random sequence was presented at the beginning (R1), followed by 15 learning sequences (S1-S15), followed by one random sequence (R2) at the end. We investigated the mean time participants took to complete the sequence (SRTT-tDCS_MTCS) and the mean time participants took to react to each upcoming item (SRTT_tDCS_ReT). Descriptives among other things include the number of recalled items participants would recall at the end of the second day (max: 12 items) and responses from a visual analog scale asking for Attention (A), Fatigue (F) and Discomfort (D) on a 1-10 scale.

受试者在接受为期20分钟的经颅直流电刺激，刺激部位为单侧腿部的初级运动皮层（分组=4）、双侧背外侧前额叶皮层（分组=1）或接受安慰剂刺激（分组=3）的同时，完成了一项复杂的全身序列反应时任务。序列反应时学习在连续两天进行，两天之间的间隔为24小时。第一天，呈现了4个随机序列（R1-R4），随后是15个学习序列（S1-S15），最后再呈现一个随机序列（R5）。第二天，首先呈现1个随机序列（R1），随后是15个学习序列（S1-S15），最后再呈现一个随机序列（R2）。本研究探讨了受试者完成序列所需平均时间（序列反应时-tDCS-运动皮层）以及受试者对每个即将出现的项目作出反应所需平均时间（序列反应时-tDCS-反应时间）。描述性统计包括其他内容，如受试者在第二天结束时回忆的项目数量（最多12个项目）以及关于注意力（A）、疲劳（F）和不适（D）的视觉模拟评分（1-10分）。
