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. This volume explores the scientific foundations of personality and individual differences, in chapters arranged across three thematic sections: Part 1: Theoretical Perspectives on Personality and Individual Differences Part 2: Research Strategies for Studying Personality and Individual Differences Part 3: The Measurement of Personality and Individual Differences With outstanding contributions from leading scholars across the world, this is an invaluable resource for researchers and graduate students.

Individual differences are essential to the process of evolution by natural selection. Natural selection is the only known process capable of creating and maintaining adaptations. The properties of inheritance, variation, and differential reproduction are required for evolution of adaptations (see Sela and Shackelford, 2015, for a review). Physiological and psychological traits must be genetically heritable and reliably passed from parent to offspring in order for natural selection to act upon them. Some individuals propagate their genes more successfully than do others, resulting in differential reproduction. Ultimately, the number of successful offspring (and the number of their successful offspring, etc.) determines gene frequency of particular traits in a population. Survival ...
