Raw Data: Visual plasticity and exercise revisited: no evidence for a "cycling lane"

Data as recorded by binocular rivalry program in comma-separated-variable format. One file per block. The first line of the file indicates the orientation of the grating shown to each eye. The events are given with the time (in seconds) that the event occurred.<br>Three types of button presses were made by subjects, either indicating the percept of a <i><b>left</b></i> oblique grating (angle +45), a <i><b>right</b></i> oblique grating (angle -45), or a <i><b>mixed</b></i> percept of the two. Note that the left and right oblique gratings only correspond to the left and right <i>eyes </i>for one of the two possible stimulus arrangements (where the left oblique grating is presented to the left eye and the right oblique grating is presented to the right eye, coded as"Left 45 Right -45"). It is therefore necessary to convert these grating orientation responses into the equivalent <i>eye</i> responses in subsequent data processing.<br>The responses are sampled from the keyboard roughly every 0.01 seconds. For the two earliest tested subjects (S1 and S7) every sample is written to the file, so a continued keypress will result in many of the same response being recorded (~100 per second). To reduce the file size and simplify analysis, for subsequent subjects we recorded only when the response had <i>changed</i> from the previous sample. Deleting the duplicated responses from S1 and S7 is a trivial step in data pre-processing. Response durations are therefore the difference in time between the beginning of that response (e.g. when the program recorded a "left" button press) and the beginning of the next different response (e.g. the program records a "mixed" button press). Therefore the duration of the final response is not specified, as it is terminated by the end of the testing rather than a keyboard response indicating a perceptual transition.

本数据集为双眼竞争（binocular rivalry）实验程序记录的数据，采用逗号分隔值（comma-separated variable, CSV）格式存储，每个实验块对应一个数据文件。
文件首行标明了分别呈献给左右眼的光栅朝向。所有实验事件均附带其发生时刻（单位：秒）。
被试可执行三种按键操作，分别对应报告感知到**左斜向**光栅（朝向角+45°）、**右斜向**光栅（朝向角-45°），或两种光栅的**混合**感知状态。
需注意：仅在一种刺激呈现配置下（即左斜向光栅呈献给左眼、右斜向光栅呈献给右眼，编码为"Left 45 Right -45"），左、右斜向光栅才分别对应左、右眼。因此在后续数据处理中，需将基于光栅朝向的按键反应转换为对应的眼感知反应。
按键反应以约每0.01秒的频率从键盘采样。对于首批两名被试（S1与S7），所有采样数据均会写入文件，因此若被试持续按住同一按键，会记录到大量重复的反应数据（约每秒100条）。
为缩减文件体积并简化分析流程，后续被试的数据仅在反应与前一次采样发生变化时才会写入文件。对S1与S7的数据删除重复响应，属于数据预处理中极为简单的步骤。
因此，单次反应的持续时长为该反应起始时刻（例如程序记录到“左”按键按下的时刻）与下一次不同反应的起始时刻（例如程序记录到“混合”按键按下的时刻）之间的时间差。由此，最后一次反应的持续时长无法被记录，因为其终止于实验结束而非被试报告感知转换的按键操作。
