Another issue, Dr. Bex says, is that the results of perceptual learning sometimes apply only very narrowly to the tasks practiced in training. The ability to read small print may improve, but it's unclear how much difference that makes for people in a wider range of daily tasks.
贝克斯博士表示,另一个问题是知觉学习的效果有时仅仅局限于在训练中练习过的任务。阅读小字的能力可能会有所提高,但目前还不清楚这项训练能在多大程度上提高人们完成更广泛日常任务的能力。
A study, presented in July at the Asia-Pacific Conference on Vision in China, found that the GlassesOff program improved performance on measures including contrast sensitivity -- suggesting the improvement will apply to a wide range of daily tasks, Mr. Madar says.
马达尔说,7月份在中国举行的亚太视觉会议(Asia-Pacific Conference on Vision)上宣读的一项研究成果显示,GlassesOff的项目改善了对比敏感度等指标――暗示该应用能改善人们完成广泛日常任务的能力。
