40名观察者参加了一项研究，研究年龄对中央和周边视觉运动检测的影响。对20名年轻观察者和20名年长观察者（每组10男10女）进行板层流（实验1）和径向流（实验2）检测。运动阈值测量角度为0,10,20和40的中央凹。结果表明，老年人和年轻人在这两种运动类型上存在显著差异。年龄的影响是由观察者的性别和显示的视网膜偏心介导的。年龄较大的女性在中央凹处显示出较高的板层血流阈值，这与先前的发现一致。研究结果表明，与年龄相关的视觉信息处理变化受到运动处理系统时间特征变化的影响。提出了一种采用两种不同的处理流来恢复和使用运动信息的模型。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Forty observers participated in a study examining the effect of age on the detection of motion in central and peripheral vision. Detection of lamellar (Experiment 1) and radial flow (Experiment 2) was measured for 20 younger observers and 20 older observers (10 men and 10 women in each group). Motion thresholds were measured for angles of 0, 10, 20, and 40 off fovea. The results indicated significant differences between older and younger adults for both motion types. The effect of age was mediated by the gender of the observer as well as the retinal eccentricity of the display. Older women showed higher thresholds for lamellar flow at fovea consistent with previous findings. The findings suggest that age-related changes in visual information processing are affected by changes in the temporal characteristics of the motion processing system. A model is proposed in which 2 different streams of processing are used for the recovery and use of motion information.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
