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 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. This book: ● Explains how to understand personality types in various contexts, including sales, recruiting, coaching ● Provides guidelines for using personality data to learn and execute ● Explores ethics and compliance considerations surrounding the use of Personality AI ● Offers valuable insights from a leader in the business applications of Personality AI Predicting Personality: Using AI to Understand People and Win More Business is a must-have guide for C-suite executives, sales and marketing professionals, coaches, recruiters, and business owners.

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

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.

Dark personality traits, and traits with dark features, are connected to destructive behaviors and interpersonal problems. Even moderate levels of these traits can cause significant issues. Understanding them will play an integral role in treating individuals who exhibit dark, unhealthy characteristics. Thus, a primary goal of this book is to unite personality psychology and clinical psychology. It synthesizes recent research that connects pathological personality features to the Big Five personality dimensions, creating an interdisciplinary taxonomy of dark personality traits. This volume brings together a diverse panel of experts who provide complex, nuanced perspectives on a variety of personality traits, including those that are readily accepted as dark (e.g., the Dark Triad of narcissism, psychopathy, and Machiavellianism), have been largely ignored by the broader psychological literature (e.g., spitefulness), have not been included in previous discussions of dark personality traits (e.g., authoritarianism), or appear to be at least somewhat positive on a superficial level (e.g., perfectionism and fearless dominance). Chapters explore both maladaptive and adaptive features of these traits, including how to address them in clinical settings. The final chapter ties the entire volume together with a thorough review of common themes, clinical implications, and research goals across all traits.

Accuracy in judging personality is important in clinical assessment, applied settings, and everyday life. Personality judgments are important in assessing job candidates, choosing friends, and determining who we can trust and rely on in our personal lives. Thus, the accuracy of those judgments is important to both individuals and organizations. In examining personality judgment, Personality Judgment takes a sweeping look at the field's history, assumptions, and current research findings. The book explores the construct of traits within the person-situation debate, defends the human judge in the face of the fundamental attribution error, and discusses research on four categories of moderators in judgment: the good judge, the judgeable target, the trait being judged, and the information on which the judgment is based. Spanning two decades of accuracy research, this book makes clear not only how personality judgment has come to its current standing but also where it may move in the future. Covers 20 years worth of historical, current and future trends in personality judgment Includes discussions of debatable issues related to accuracy and error. The author is well known for his recently developed theoy of the process by which one person may render an accurate judgment of the personality traits of another

Personality is now understood to be a function of both biological and environmental influences. This revised and updated edition of Psychobiology of Personality describes what is currently known about the biological basis of the primary personality traits, including genetic, neurological, biochemical, physiological, and behavioral influences. Emphasis is placed on understanding the connections between phenomena at these levels. The research discussed makes use of animal models, based on experimental brain research, as well as human clinical and normal personality research. Chapters are devoted to temperament and personality trait structure, psychobiological methods, and each of four major personality traits: extraversion, impulsive, sensation seeking, and aggression. Recent advances in psychobiological methods, such as molecular genetics and brain imaging have enabled us to begin to unravel the genetic and neurological sources of behavior and personality. These advances are discussed in this new edition, making it essential reading for advanced students of psychology and psychiatry.
