There is a growing knowledge base in understanding the differences and similarities between women and men, as well as the diversities among women and sexualities. Although genetic and biological characteristics define human beings conventionally as women and men, their experiences are contextualized in multiple dimensions in terms of gender, sexuality, class, age, ethnicity, and other social dimensions. Beyond the biological and genetic basis of gender differences, gender intersects with culture and other social locations which affect the socialization and development of women across their life span. This handbook provides a comprehensive and up-to-date resource to understand the intersectionality of gender differences, to dispel myths, and to examine gender-relevant as well as culturally relevant implications and appropriate interventions. Featuring a truly international mix of contributors, and incorporating cross-cultural research and comparative perspectives, this handbook will inform mainstream psychology of the international literature on the psychology of women and gender.
