Abstract

Purpose: The purpose of this study was to investigate the short- and long-term learning effect of dynamic visual acuity (DVA) tests.

Methods: Participants between 18 and 30 years with corrected to normal visual acuity were enrolled in this study. Three repeated sessions were performed, with 15 minutes and 15 days' intervals between sessions. Each session included 9 DVA tests of horizontal, vertical, and diagonal motions of E optotypes at 20, 40, and 80 degrees per second (dps). The short- and long-term learning effects were analyzed from repeated DVA tests.

Results: Of the 58 enrolled participants, the mean age was 23.1 ± 2.1 years. DVA significantly varied among motion types and velocities (P < 0.05, respectively). There was a significant short-term learning effect for 20 (P = 0.004), 40 (P < 0.001), and 80 (P = 0.014) dps DVA test of horizontal motion, 40 dps DVA test of vertical (P = 0.003), and diagonal motion (P = 0.036). The long-term learning effect was detected in the 40 dps diagonal motion DVA test (P = 0.015). The short- and long-term learning effects were positively associated with initial DVA in most combinations of motion type and velocity tests (P < 0.05, respectively). The short- (P = 0.031) and long-term (P = 0.024) learning effect of 80 dps horizontal motion DVA test was greater in male than female participants.

Conclusions: There is a significant short-term learning effect in the DVA test of various motion types, but the long-term learning effect was rarely observed, and it is greater in participants with worse initial DVA.

临床动态视力测试的短期和长期感知学习。
目的:本研究旨在调查动态视力(DVA)测试的短期和长期学习效果:方法:本研究招募了 18 至 30 岁、视力矫正为正常的参与者。重复进行三次,每次15分钟,每次间隔15天。每个疗程包括 9 次 DVA 测试,测试 E 光型的水平、垂直和对角运动,速度分别为每秒 20、40 和 80 度(dps)。通过重复的 DVA 测试分析了短期和长期的学习效果:结果:58 名参与者的平均年龄为 23.1±2.1 岁。不同运动类型和速度的 DVA 有明显差异(P < 0.05)。20(P = 0.004)、40(P < 0.001)和 80(P = 0.014)dps 水平运动 DVA 测试、40 dps 垂直运动 DVA 测试(P = 0.003)和对角线运动 DVA 测试(P = 0.036)存在明显的短期学习效应。在 40 dps 对角线运动 DVA 测试中发现了长期学习效应(P = 0.015)。在大多数运动类型和速度测试组合中,短期和长期学习效应与初始 DVA 呈正相关(P 分别 < 0.05)。在 80 dps 水平运动 DVA 测试中,男性参与者的短期学习效应(P = 0.031)和长期学习效应(P = 0.024)均大于女性参与者:结论:在各种运动类型的 DVA 测试中存在明显的短期学习效应,但很少观察到长期学习效应,而且这种效应在初始 DVA 较差的参与者中更大。
