Execution Of Saccadic Eye Movements Affects Speed Perception

This depository contains the data from different experiments regarding the perceived speed of moving targets tracked with different oculomotor behavior. The folders "Gap Paradigm" and "Step Paradigm" contain the main data for the manuscript. The folders "Vertical Offset Control" and "Awareness of Saccades" data from additional control experiments. In the folders "Gap Paradigm" and "Step Paradigm" you will find additional folders seperating the conditions for the collected data. One "Pilot" Folder contains the data used in the pilot experiment to determine the relevant eye crossing times. The "Speed Discrimination" Folder contains the files where participants made judgements about moving objects while tracking it with the eyes. In the "Fixation" folder you find the data for the fixation control where observes saw the same stimulus as during the speed discrimination task, but where not allowed to track the moving object. For each of the experiments we have a folder for the seperate blocks of the participant, which contains a logfile which specifys the parameters used for all trials and seperate files which contain information about the eye position during each trial. The structure of the eye position files is always the same: time, x-position, y-position, events marked by the eyelink. The x- and y-position are coded in pixels on the screen. The parameters specified in the log-fileare explained in an additional readme file.本数据集库收录了针对不同动眼行为下追踪运动目标感知速度的多项实验数据。 其中，"Gap Paradigm（间隙范式）"与"Step Paradigm（阶跃范式）"文件夹包含了本研究论文的核心实验数据；"Vertical Offset Control（垂直偏移对照）"与"Awareness of Saccades（扫视觉知）"文件夹则收录了额外对照实验的数据。 在"Gap Paradigm"和"Step Paradigm"文件夹内，可找到按实验条件划分的子文件夹。其中"Pilot（预实验）"文件夹收录了用于确定关键眼动交叉时长的预实验数据；"Speed Discrimination（速度辨别）"文件夹包含了被试在以眼球追踪运动物体时对其速度进行判断的相关文件；"Fixation（固视对照）"文件夹收录了固视对照实验的数据，该实验中观察者所接收的刺激与速度辨别任务一致，但被要求不得追踪运动物体。 每项实验均设有对应被试分组的文件夹，其中包含一份日志文件，用于说明所有试次的实验参数，以及多个单独文件，用于记录每一试次过程中的眼位信息。 眼位文件的格式统一为：时间、x轴位置、y轴位置、Eyelink眼动仪标记的事件。x轴与y轴位置以屏幕像素为单位编码。日志文件中提及的实验参数将在附加的README文件中详细说明。
