二阶运动条件下闪现滞后现象的研究
闪现滞后现象(Flash-lag effect) 视网膜(Retina) 运动外推机制(Motion extrapolation) 二阶运动(The first order motion)
2008/3/6
闪现滞后现象（flash-lag effect）是指运动物体旁闪现的物体在知觉中物体落后于运动物体的现象。对这个现象，有一种解释认为视网膜上对运动刺激的外推机制对闪现滞后现象有相当的贡献。用视网膜外推机制不再有效的二阶运动刺激取代前人实验中的一阶运动刺激来研究闪现滞后现象，发现在视网膜推断机制失效的情况下，闪现滞后现象并没有减小，而是和一阶运动刺激条件下的量相当。结果表明，视网膜上的加工机制并...
