Abstract

BACKGROUND

Zorzi et al. (2012, Proc. Natl. Acad. Sci. U.S.A., 109, 11455) found evidence that extra-large letter spacing aids children with dyslexia, but the evidence for the coloured overlays is contradictory (e.g., Henderson et al., 2013, J. Res. Special Educ. Needs, 13, 57; Wilkins, 2002, Ophthalmic Physiol. Opt., 22, 448), and possible combined advantages have not been identified.

AIMS

To investigate whether extra-large letter spacing or coloured overlays can alleviate reading problems in dyslexic adults.

SAMPLE

The participants were 24 dyslexic and 24 non-dyslexic university students, matched for age and fluid intelligence.

METHODS

The reading speed and the errors made by a dyslexic and a control group were measured in four conditions: with and without coloured overlays and with normally and largely spaced texts.

RESULTS

Large letter spacing improves the reading speed in general, as well as improves the reading accuracy in dyslexic readers.

CONCLUSIONS

The results support the positive effect of letter spacing on reading performance.

背景

佐尔齐等人（2012年，《美国国家科学院院刊》，第109卷，第11455页）发现有证据表明，超大字母间距对诵读困难儿童有帮助，但关于彩色覆盖层的证据则相互矛盾（例如，亨德森等人，2013年，《特殊教育需求研究杂志》，第13卷，第57页；威尔金斯，2002年，《眼科生理光学》，第22卷，第448页），而且尚未发现可能的综合优势。
