Gender encompasses biological sex but extends beyond it to the socially prescribed roles deemed appropriate for each sex by the culture in which we live. The gender roles we each carry out are highly individualistic, built on our biological and physical traits, appearance and personality, life experiences such as childhood, career and education, and history of sexual and romantic interactions. Each element influences perceptions and expectations. Gender-related experiences influence and shape the ways we think about others and ourselves including self-image, behaviour, mood, social advancement and coping strategies. This new book brings together leading international research devoted to this subject.
