Developmental Dyslexia: Theory and Research Paradigm

目前对发展性阅读障碍(Developmental Dyslexia,DD)的理论解释主要有语音缺陷论、小脑缺陷论及一般性大细胞功能障碍理论。在这些理论基础上,研究者们采用Oddball范式、侧抑制范式、RSVP范式、TOT范式、半视野呈现范式以及错误记忆范式等对DD的特点与本质进行了全面系统的研究。本文简略阐述了DD的理论基础以及DD研究中的各种实验范式,以期更多的人参与到DD的实验研究中来。

At present, three theories about developmental dyslexia are popular, namely phonological deficit, cerebella deficit and the general magnocellular dysfunction. On the basis of these theories, researchers systematically explore the characteristics and the nature of developmental dyslexia through plentiful experimental paradigms, such as oddball paradigm, flanker effect paradigm, RSVP paradigm, TOT paradigm, visual half-field presentation paradigm and false memory paradigm. This article briefly discusses the theoretical basis and the experimental paradigms of developmental dyslexia, aiming at attracting more researchers to participate in the experimental research.
