在Corbalis等人(1985，Cortex 21 225-236)工作的基础上，我们考察了正常读者和发展性阅读障碍者对字母(实验1)和字母和形状(实验2)的心理旋转。虽然两组中形状的总体反应时间相同，但对于字母，阅读障碍患者的反应速度较慢。然而，对于字母和形状，两组之间获得了相同的心理旋转效应。这一结果被解释为支持发育性阅读困难的概念，即字形和音素字母表征之间的功能协调不足。
Extending the work of Corballis et al (1985, Cortex 21 225-236), we investigated mental rotation of letters (experiment 1), and of letters and shapes (experiment 2) in normal readers and developmental dyslexics. Whereas the overall response times were equal for shapes in both groups, for letters they were slower in dyslexics. For letters as well as for shapes, however, the same mental-rotation effects were obtained between the groups. The results are interpreted as support for the notion of developmental dyslexia as a deficit in functional coordination between graphemic and phonological letter representations.
