How do we come to be who we are? Why do we differ in our personalities? How do these differences matter in life? Individual Differences and Personality aims to describe how and why personality varies among people. Unlike books that focus on individual theorists, this book focuses on current research and theory on the nature of personality and related individual differences. The book begins by discussing how personality is measured, the concept of a personality trait, and the basic dimensions of personality. This leads to a discussion of the origins of personality, with descriptions of its developmental course, its biological causes, its genetic and environmental influences, and its evolutionary function. The concept of a personality disorder is then described, followed by a discussion of the influence of personality on life outcomes in relationships, work, and health. Finally, the book examines the important differences between individuals in the realms of mental abilities, of beliefs and attitudes, and of behavior. Presents a scientific approach to personality and related individual differences, as well as theory and research on the fundamental questions about human psychological variation New edition presents findings from dozens of new research studies of the past six years Includes new chapter on vocational interests and a revised chapter on personality disorders reflecting DSM-5 formulation Contains streamlined descriptions of measurement concepts and heritability research Includes various boxes containing interesting asides that help to maintain the student’s attention.

The definitive guide to using this ancient psychological system to gain self-knowledge and achieve personal growth—now expanded and revised. The Enneagram is an extraordinary framework for understanding more about ourselves. No matter from which point of view we approach it, we discover fresh conjunctions of new and old ideas. So writes Don Riso in this expanded edition of his classic interpretation of the Enneagram, the ancient psychological system used to understand the human personality. In addition to updating the descriptions of the nine personality types, Personality Types, Revised greatly expands the accompanying guidelines and, for the first time, uncovers the Core Dynamics, or Levels of Development, within each type. This skeletal system provides far more information about the inner tension and movements of the nine personalities than has previously been published. This increased specificity will allow therapists, social workers, personnel managers, students of the Enneagram, and general readers alike to use it with much greater precision as they unlock the secrets of self-understanding, and thus self-transformation. “No Enneagram teachers I’ve come across offer such a rich and dynamic picture of how each personality type expresses itself in the world, and the process by which we can move through progressive stages of psychological and spiritual growth.”—Tony Schwartz, author of What Really Matters: Searching for Wisdom in America

This essential textbook examines what personality traits are, how they influence human behaviour and the applications of personality assessment.

The ultimate playbook for using artificial intelligence to communicate effectively, build teams, and win customers Not long ago, we imagined a hyper-connected world full of trust and openness—a world where effortless communication would bring about a new understanding between people everywhere. Judging from our current environment, this vision of the future may have been overly optimistic. With infinite channels and countless voices flooding them with messages, most people have become highly skeptical and guarded by necessity. As a result, communication is much harder than ever before. Despite the unprecedented connectivity enabled by modern technology, we are far less likely to trust and to invest the time needed to build strong relationships. How can we use technology to reverse this trend? A groundbreaking new branch of artificial intelligence—Personality AI—may be the answer. Combining traditional machine learning, data analytics, and behavioral psychology, Personality AI helps professional communicators tear down walls, establish trust with their audiences, and utilize data to build meaningful relationships, strengthen empathy, and win more customers. Predicting Personality is a practical, real-world playbook for any individual or business whose success hinges on the ability to communicate effectively and build teams. Authors Drew D’Agostino and Greg Skloot—CEO and President, respectively, of Crystal, the app that tells you anyone's personality—show you how businesses can leverage Personality AI and machine learning to grow faster and communicate more effectively than was previously possible. This reader-friendly guide teaches you what Personality AI is, how it works, and demonstrates its practical applications in both life and business.

Award-winning psychology writer Annie Paul delivers a scathing exposé on the history and effects of personality tests. Millions of people worldwide take personality tests each year to direct their education, to decide on a career, to determine if they'll be hired, to join the armed forces, and to settle legal disputes. Yet, according to award-winning psychology writer Annie Murphy Paul, the sheer number of tests administered obscures a simple fact: they don't work. Most personality tests are seriously flawed, and sometimes unequivocally wrong. They fail the field's own standards of validity and reliability. They ask intrusive questions. They produce descriptions of people that are nothing like human beings as they actually are: complicated, contradictory, changeable across time and place. The Cult Of Personality Testing documents, for the first time, the disturbing consequences of these tests. Children are being labeled in limiting ways. Businesses and the government are wasting hundreds of millions of dollars every year, only to make ill-informed decisions about hiring and firing. Job seekers are having their privacy invaded and their rights trampled, and our judicial system is being undermined by faulty evidence. Paul's eye-opening chronicle reveals the fascinating history behind a lucrative and largely unregulated business. Captivating, insightful, and sometimes shocking, The Cult Of Personality Testing offers an exhilarating trip into the human mind and heart.
