When first published in 2005, Why Gender Matters broke ground in illuminating differences between boys and girls-how they perceive the world, learn, process emotions, and take risks. Dr. Sax showed that when we overlook their differences, we may end up reinforcing damaging stereotypes and fail to help our kids reach their full potential. In the years since, the world has changed. An avalanche of new research supports, deepens, and expands Dr. Sax's work. This indispensable guide for parents and educators is thoroughly revised and updated to include new findings about how boys and girls interact with social media and video games; differences in how they see, hear, and smell; and guidance about how to support gender-nonconforming, LGB, and transgender kids. Dr. Sax accessibly weaves the science with stories and insights from his decades of clinical experience to show how to raise happier, healthier kids. Book jacket.
