Since the mid-20th century, there have been dramatic changes in our conception of how bilingualism affects children’s cognitive development, moving from one of certain negativity, to unlimited advantage, and finally resting in a current state defined largely by confusion because of the complexity in how bilingualism is defined. However, the question has great consequences, so it is important to evaluate the evidence to understand the impact. Such information determines how families make decisions about their home language, particularly regarding the maintenance of heritage languages; how schools offer programs based on alternative languages; how clinicians assess children for learning or other special needs; and how communities offer services to diverse members. By defining the concepts more precisely than has typically been the case, the complexity of the relation between bilingualism and cognition becomes clear. The evidence shows that bilingualism impacts cognitive level and brain function across the lifespan, but the nature and extent of those effects are modified by the type and degree of bilingualism and the nature of the task. Understanding the conditions under which various effects emerge is essential for interpreting the effects of bilingualism on children’s cognitive development and their potential role in education.

Gender Differences in Reading, Writing and Language Development
David Reilly
The topic of gender differences in reading, writing, and language development has long been of interest to parents, educators, and public-policy makers. While some researchers have claimed that gender differences in verbal and language abilities are disappearing, careful evaluation of the scientific research shows otherwise. Examination of nationally representative samples of educational achievement data show that there are moderately sized gender differences in reading achievement favoring girls and women (d = −0.19 to −0.44 across age groups), and substantially larger gender differences in writing (d = −0.42 to −0.62), spelling (d = −0.39 to −0.50), and grammar (d = −0.39 to −0.42). Explanations for observed gender differences in verbal and language abilities suggest a complex network of biological, social, and cultural forces rather than any single factor.
