摘要： 采用随机点阵范式和实验内元分析技术，首次分离水平、垂直、旋转和径向运动形式下两两对立方向的运动一致性阈值，探究整体运动知觉（GMP）老化的方向不同步性及总效应。结果发现：四种运动形式下，老年组阈值均显著高于青年组，且元分析显示两组阈值之差的效应量大于0，表明相对于青年人，老年人的GMP存在显著下降。同时，老年组向右、向下、顺时针和外扩方向的阈值显著高于其对立方向及青年组，表明老年人这些方向的GMP衰退更加严重，提示GMP的老化存在方向不同步性。

Abstract: The present study adopted random dots kinematograms paradigm and internal mini meta-analysis to investigate the directional asynchrony and the total effect of global motion perception (GMP) aging, by separating the motion coherence thresholds of two opposite directions in horizontal, vertical, rotational and radial motion. Results showed that older adults’ thresholds were significantly higher than the younger under the four motion conditions, and the effect size of the mean difference between the two groups’ thresholds was greater than 0, indicating that there was an age-related decline in GMP. Meanwhile, the thresholds of rightward, downward, clockwise and expansion for the older adults were significantly higher than that of the opposite directions, and significantly higher than those for the younger, suggesting that GMP decline in these directions for the older adults is more serious, indicating the existence of directional asynchrony in GMP aging.
