The current research examined performance of good and poor readers of Thai on two tasks that assess sensitivity to dynamic visual displays. Readers of Thai, a complex alphabetic script that nonetheless has a regular orthography, were chosen in order to contrast patterns of performance with readers of Korean Hangul (a similarly regular language but one that has a simple visual format, see ). Thai poor readers were less sensitive than good readers on the two measures of dynamic visual processing; they had higher thresholds for detecting coherent movement and required longer ISIs to report group movement in the Ternus task. These results differ from those for poor readers of Korean Hangul that found no relationship between visual processing thresholds and reading skill. This contrast suggests that the expression of visual processing problems in dyslexia is mediated by the format properties of the writing system and points to the need to consider such factors in formulating brain-behavior relationships.
当前研究考察了泰语阅读能力强和弱的读者在两项评估对动态视觉显示敏感度的任务中的表现。泰语是一种复杂的字母文字，但拼写规则，选择泰语读者是为了与韩语（一种同样规则但视觉形式简单的语言，见 ）读者的表现模式进行对比。在动态视觉处理的两项指标上，泰语阅读能力差的读者比阅读能力好的读者敏感度更低；在检测连贯运动方面，他们的阈值更高，并且在特纳斯任务中报告群体运动需要更长的刺激间隔时间。这些结果与韩语阅读能力差的读者的结果不同，后者发现视觉处理阈值与阅读技能之间没有关系。这种对比表明，阅读障碍中视觉处理问题的表现是由书写系统的形式属性介导的，并指出在构建脑与行为的关系时需要考虑这些因素。
