Dyslexia, lateralization and sexThe subject of this paper is the relationship between dyslexia and both lateralization and sex. Presented are some research results that have now for many years contradicted the, well established in diagnostic practice, belief that there exists an influence of crossed or undeveloped lateralization on reading disabilities. Some newer results are also discussed, which indicate that – contrary to former reports – among the children suffering from dyslexia boys are only a slight majority, if any at all. In this context the author’s own research is presented, during the course of which no significant differences in frequency of occurring of different lateralization formulas were found between a group of children at risk of dyslexia and a control group. Furthermore, the risk of dyslexia occured with the same frequency in both sexes, although some differences in nature of the disabilities of boys and girls were observed.
