本方案描述了扫视眼动数据的获取和评估，用于基础神经科学研究和临床应用。实验方案要求受试者根据在连续试验中随机呈现的视觉刺激做出扫视眼动。描述了间隙和重叠范式以及产生顺向或反向扫视的指令。该方案包括扫视检测的描述、扫视起始、结束、幅度和速度的确定、不同类型试验比例的精确计算方法以及不稳定或伪迹试验的处理。定义了相关变量。描述并分析了从大量（300名）不同年龄（8 - 65岁）受试者获得的结果随年龄的发展情况。该方案允许在许多不同情况下测试受试者的扫视状态，特别是在神经病学、精神病学和心理学的诊断辅助方面。（C）1997年爱思唯尔科学出版社（Elsevier Science B.V.）
This protocol describes the acquisition and evaluation of saccadic eye movement data for use in basic neuroscience research and clinical application. The experimental protocol requires the subject to make saccadic eye movements in response to visual stimuli presented, in random order, on consecutive trials. The gap and overlap paradigms are described together with the instruction to generate pro-or antisaccades. The protocol includes the description of saccade detection, the determination of the beginning, the end, the size, and the velocity of a saccade, the exact way of calculating the proportion of different kinds of trials, and the treatment of erratic or artifact trials. Relevant variables are defined. The results obtained from a large number (300) of subjects of different ages (8-65 years) are described and analysed with respect to their development with age. The protocol allows to test a subject's saccadic status in many different circumstances in particular with respect to diagnostic help in neurology, psychiatry and psychology.
