Final answer:
The claim that dyslexia is more common in girls than in boys is false, as research shows no significant cognitive differences between genders in reading abilities.
Step-by-step explanation:
The statement that dyslexia is much more common in girls than in boys is false. Dyslexia is a common learning disability that affects the ability to process letters and sounds, but it does not disproportionately affect one gender more than the other. Research, including the work of Anne Fausto-Sterling, shows that there are no statistically significant differences in cognitive abilities, including reading, between boys and girls. Furthermore, gender biases in classroom behaviors, as documented by Sadker and Sadker, along with Thorne and Ready, indicate societal influences on perceived abilities rather than inherent differences in capabilities related to conditions like dyslexia.
