Perceptual Learning

This exploratory study investigates whether perceptual learning using blurred Gabor stimuli can improve uncorrected distance visual acuity in children aged 6-10 years with low myopia. Participants will be randomly assigned to a training group or control group. The training group will undergo individualized visual perceptual learning through a digital Vision Training System (VTS) for approximately 3 months. The study will also evaluate changes in refraction, contrast sensitivity, visual crowding, Chinese reading acuity with eye movements, and sweep visual evoked potentials (sVEPs).

Restorative visual rehabilitation is frequently used to enhance the visual development and function of children with low vision. An important strategy within this field is visual stimulation, which is particularly used for infants and toddlers with low vision, as well as for children who have both developmental disabilities and low vision.This study has two primary objectives.The first objective is to examine the effect of using intensive, specific, and flickering black-and-white checkerboard patterns to enhance visual function in children with mild to moderate low vision. The second objective is to develop a visual stimulation program tailored for children with severe or profound multiple disabilities and visual impairments, and to evaluate its effectiveness. For both objectives, the visual stimulation intervention will be provided through either in-person or remote delivery

The purpose of this study is to investigate how our performance changes after our perceptual system is trained in a certain way ("perceptual learning"). In addition, investigators are interested in identifying and characterizing relationships between such changes and neuroimaging signals recorded from the human brain.
