Prescheduled Interleaving of Processing Reduces Interference in Motor-Cognitive Dual Tasks
收藏资源简介：
All performance-data sets are provided in three seperate .txt-files for each subject. Subject_##_CognitiveTask.txt consists of a chronology table of 8 columns and subject depent number of rows for the 2-back task. col. 1: "Stimulus number" = running number of n stimuli ("0001,0002, ..., n").<br> col. 2: "Day" = Number of the testing day, which is:<br> "1" for day 1, <br> "2" for day 2, or<br> "3" for day 3.<br> col. 3: "Walking Speed [km/h]" = Speed condition of the testing day, which is:<br> "3" for 3 km/h,<br> "4" for 4 km/h, or<br> "5" for 5 km/h.<br> col. 4: "Test block" = Each day includes seven test blocks, where:<br> "1" is the Sitting condition conducted twice, in the beginning and the end of each testing day.<br> "2" is the 0% condition,<br> "3" is the 50% condition,<br> "4" is the 75% condition,<br> "5" is the Earlier condition, and<br> "6" is the Later condition.<br> col. 5: "Trial" = "1" is the first trial,<br> "2" is the second trial, and<br> "3" is the third trial.<br> col. 6: "Reaction time [ms]" = Reaction time data in milliseconds as floating-point numbers. Missing values are substituted by a "NaN" signature.<br> col. 7: "Required decision" = This column shows, whether there was a matching ("1") or a non-matching ("0") required in the 2-back task. Missing values are substituted by a "NaN" signature.<br> col. 8: "Performed decision" = The column shows, whether the subject responded indicating a matching ("1") or a non-matching ("0") in the 2-back task. Missing values are substituted by a "NaN" signature. <br> Subject_##_MotorTask_StrideDuration.txt consists of a chronology table of 7 columns and subject depent number of rows for walking strides under single-task and dual-task condition. col. 1: Stride number" = running number of n strides ("0001,0002, ..., n").<br> col. 2: "Day" = Number of the testing day, which is:<br> "1" for day 1, <br> "2" for day 2, or<br> "3" for day 3.<br> col. 3: "Walking Speed [km/h]" = Speed condition of the testing day, which is:<br> "3" for 3 km/h,<br> "4" for 4 km/h, or<br> "5" for 5 km/h.<br> col. 4: "Test block" = Each day includes seven test blocks, where:<br> "2" is the 0% condition,<br> "3" is the 50% condition,<br> "4" is the 75% condition,<br> "5" is the Earlier condition, and<br> "6" is the Later condition.<br> col. 5: "Trial" = Each block consisted of six trials ("1, 2,..., or 6").<br> col. 6: "Task condition" = shows whether the trial was instructed as a single-task ("1") or as a motor-cognitive dualtask ("2").<br> col. 7: "Stride duration [s]" = The duration of each detected stride is written in seconds. Missing values are substituted by a "NaN" signature. <br> Subject_##_MotorTask_StrideLength.txt consists of a chronology table of 7 columns and subject depent number of rows for walking strides under single-task and dual-task condition. col. 1: Stride number" = running number of n strides ("0001,0002, ..., n").<br> col. 2: "Day" = Number of the testing day, which is:<br> "1" for day 1, <br> "2" for day 2, or<br> "3" for day 3.<br> col. 3: "Walking Speed [km/h]" = Speed condition of the testing day, which is:<br> "3" for 3 km/h,<br> "4" for 4 km/h, or<br> "5" for 5 km/h.<br> col. 4: "Test block" = Each day includes seven test blocks, where:<br> "2" is the 0% condition,<br> "3" is the 50% condition,<br> "4" is the 75% condition,<br> "5" is the Earlier condition, and<br> "6" is the Later condition.<br> col. 5: "Trial" = Each block consisted of six trials ("1, 2,..., or 6").<br> col. 6: "Task condition" = shows whether the trial was instructed as a single-task ("1") or as a motor-cognitive dual task ("2").<br> col. 7: "Stride duration [mm]" = The length of each detected stride is written in millimeter. Missing values are substituted by a "NaN" signature.
