This survey of literature summarizes the findings of current research on sex differences in reading: studies relating to the validity of the sex-difference claim, studies examining the relationship between maturation factors and environmental characteristics, research concerned with factors in the home and school, and studies concerned with the reading task itself. Although the causes of sex differences in reading remain debatable, it can be said that the majority of the authors surveyed believe that such differences exist. A bibiliography of resources and studies relating to sex differences in reading is included. (KS)
