Visual persistence was investigated in adults with and without dyslexia in order to determine whether the adults with dyslexia demonstrate problems similar to those found in childhood dyslexia. Using a temporal separation threshold measure and procedures derived from signal detection theory, sensitivity to sequentially presented form information was determined for the two types of adults. The results showed that the sensitivity of the adults with dyslexia was impaired relative to that of the nondisabled adults when parts of a test stimulus were presented to adjacent retinal areas. This result suggests that, under certain conditions, visual persistence is longer for adults with dyslexia. The results are discussed within the context of a recent theory of dyslexia (Lovegrove, Martin & Slaghuis, 1986) that incorporates the operation of sustained and transient visual mechanisms.
为了确定患有阅读障碍的成年人是否表现出与儿童阅读障碍相似的问题，研究人员对有阅读障碍和无阅读障碍的成年人进行了视觉持久性调查。使用时间分离阈值测量方法和源自信号检测理论的程序，确定了这两类成年人对顺序呈现的形状信息的敏感度。结果表明，当测试刺激的部分呈现给相邻视网膜区域时，患有阅读障碍的成年人的敏感度相对于无阅读障碍的成年人有所受损。这一结果表明，在某些情况下，患有阅读障碍的成年人的视觉持久性更长。本文在最近一种阅读障碍理论（洛夫格罗夫、马丁和斯拉吉斯，1986年）的背景下对结果进行了讨论，该理论纳入了持续和瞬时视觉机制的运作。
