Motor Development and Cognition
In the current and next chapter, we present research fi ndings demonstrating sex and gender differences in development and behavior, including what is now known about how boys and girls differ in motor skills, cognitive abilities, personality, social behaviors, interests, and psychopathology and adjustment. In these two chapters, we focus primarily on the differences themselves. For the most part, we wait until later chapters to discuss the theories and empirical research that attempt to understand the reasons for these differences. In the epilogue we will return briefl y to the consideration of how biological, social, and cognitive forces work together in the gender developmental process.
