Individual Differences and Personality, Fourth Edition provides a comprehensive overview of research, including what personality is and how and why it differs between people. The book begins with a description of the study of personality and then presents basic principles of personality measurement, the concept of personality traits, and the major dimensions of personality variation. Further chapters review personality change and stability, biological causal mechanisms, genetic and environmental influences, and evolutionary adaptive function. Personality disorders are examined as well as "life outcomes" (e.g., relationships, work, health, etc.) which are predicted by personality characteristics.
In addition, the book examines important individual differences, such as mental abilities, religious beliefs, political attitudes and sexuality.

Michael C. Ashton is a professor of psychology at Brock University in St. Catharines, Ontario. He received his Ph.D. from the University of Western Ontario in 1998. As a grad student in the late 1990s, together with Kibeom Lee, he did some cross-cultural research to find out whether the “Big Five” personality dimensions found in North America could be recovered in other cultures. Using their own work and that of other researchers, they found that there were actually six personality dimensions. The “new” one was the H factor, or the Honesty-Humility Factor, was discovered and is now considered one of the six dimensions of human personality. In addition to the second edition of the textbook, Individual Differences and Personality, he is the author of numerous articles in scientific journals, and co-authored with Kibeom Lee The H Factor of Personality.
