Differences between people are a fascinating and long-standing area of psychological inquiry. However, previous research has largely been confined to studies at the descriptive level. This book tries to explain individual difference, rather than merely describe them. Explanations are derived from two major competing frameworks: the biological and social approaches to individuality. The book is based on the contributions of specialists from Europe and North America invited to represent the biological and social points of view. Thus, a direct confrontation is obtained of two approaches that, hitherto, have proceeded with virtually no reference to each other. Attention is paid to behavior genetics, psychophysiology and temperament, as well as to social learning, behavioral strategies and person-environment interactions. Differences and commonalities between the biological and social approaches are scrutinized and a common framework is outlined to stimulate future research. Due to its innovative character, the book is particularly relevant for investigators in the field. In addition, it may be fruitfully used in advanced graduate level courses in personality psychology.

A CHOICE Magazine Outstanding Academic Title of 2018. A novel approach to understanding personality, based on evidence that we share more than we realize with other mammals. This book presents the wealth of scientific evidence that our personality emerges from evolved primary emotions shared by all mammals. Yes, your dog feels love—and many other things too. These subcortically generated emotions bias our actions, alter our perceptions, guide our learning, provide the basis for our thoughts and memories, and become regulated over the course of our lives. Understanding personality development from the perspective of mammals is a groundbreaking approach, and one that sheds new light on the ways in which we as humans respond to life events, both good and bad. Jaak Panksepp, famous for discovering laughter in rats and for creating the field of affective neuroscience, died in April 2017. This book forms part of his lasting legacy and impact on a wide range of scientific and humanistic disciplines. It will be essential reading for anyone trying to understand how we act in the world, and the world’s impact on us.

Numerous reprehensible corporate, governmental, and nonprofit activities over recent years have highlighted the existence of organizational evil. Unlike other works on the topic, this book fully develops the concept of organizational evil, conceptually weaving the interchange between evil individuals (microlevel) who ultimately create the organizational environment that is evil, and the macrolevel elements of policy, culture, and manipulations of the social environment.

This book explores how our temperamental proclivities interact with our political leanings, shedding light on why people perceive the world differently. Focusing on the Five Factor Model of personality, currently the most popular framework in psychology research, the text unpacks the literature on the association between political orientations and personality traits. While only part of the puzzle, growing evidence suggests personality traits have a significant impact on our political convictions and voting patterns. In some instances, certain traits may even make individuals more prone to holding authoritarian and prejudicial views. Understanding these dynamics can help people better navigate political differences and conflicts, and will be of interest to students of personality psychology and students of political ideologies.

Personality and Everyday Functioning covers the foundations of personality theory and the impact of personality on normal functioning. Leading personality researchers present chapters on major theories of personality, such as psychoanalytic, developmental, behavioral, and constructivist, to name a few.

Ken Sheldon's comprehensive new book addresses two questions: how can individuals best integrate the different facets of themselves to achieve "optimal human being", and how can researchers best integrate the different levels of analysis within the human sciences to understand "optimal human being" in general? In the process, the book supplies two new frameworks—one for viewing the human sciences as a group, and the other for viewing personality theory within that group. Optimal Human Being features a multi-level model that moves from biologically based levels of analysis to higher, socially based levels, and demonstrates how these different levels interact to determine behavior. The author then proposes a new way of looking at personality by examining four "tiers": organismic foundations, personality traits, goals/intentions, and self-concepts, and demonstrates how these levels relate to the state of optimal human being. The book concludes with two higher levels of analysis relevant to personality—social interaction and culture—and proposes a new profile of optimal human being. Intended for researchers and students in social and personality, clinical, developmental, and industrial psychology and other social sciences, the book will also serve as a supplement in a variety of courses including personality, positive psychology, well being, personal development, and motivation.
