The examination of personality and individual differences is a major field of research in the modern discipline of psychology. Concerned with the ways humans develop an organised set of characteristics to shape themselves and the world around them, it is a study of how people come to be 'different' and 'similar' to others, on both an individual and a cultural level.
The SAGE Handbook of Personality and Individual Difference is the broadest and most comprehensive overview of the field to date. With outstanding contributions from leading scholars across the world, this is an invaluable resource for researchers and graduate students. Its three volumes cover all of the central concepts, domains and debates of this globally-expanding discipline, including the core theoretical perspectives, research strategies, as well as the origins, applications, and measurement of personality and individual difference.
