Biology Of Personality And Individual Differences

This is the first book to provide an overview of current research using cutting-edge genetic and neuroimaging methods in the study of personality. Integrating compelling lines of inquiry that until now have largely remained disparate, the volume brings together leading investigators from personality psychology; clinical psychology and psychiatry; cognitive, affective, and behavioral neuroscience; and comparative psychology. Coverage includes the structure of personality and its mapping onto biology, genetic markers for individual differences and vulnerability towards psychopathology, sex differences and age-related processes, and functional neuroimaging approaches.

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.

Capturing a scientific change in thinking about personality and individual differences, this volume provides theories and empirical evidence which suggest that personality and individual differences are central to evolved psychological mechanisms and behavioural functioning.

This Encyclopedia provides a comprehensive overview of individual differences within the domain of personality, with major sub-topics including assessment and research design, taxonomy, biological factors, evolutionary evidence, motivation, cognition and emotion, as well as gender differences, cultural considerations, and personality disorders. It is an up-to-date reference for this increasingly important area and a key resource for those who study intelligence, personality, motivation, aptitude and their variations within members of a group.

Individual Differences and Personality provides a student-friendly introduction to both classic and cutting-edge research into personality, mood, motivation and intelligence, and their applications in psychology and in fields such as health, education and sporting achievement. Including a new chapter on 'toxic' personality traits, and an additional chapter on applications in real-life settings, this fourth edition has been thoroughly updated and uniquely covers the necessary psychometric methodology needed to understand modern theories. It also develops deep processing and effective learning by encouraging a critical evaluation of both older and modern theories and methodologies, including the Dark Triad, emotional intelligence and psychopathy. Gardner’s and hierarchical theories of intelligence, and modern theories of mood and motivation are discussed and evaluated, and the processes which cause people to differ in personality and intelligence are explored in detail. Six chapters provide a non-mathematical grounding in psychometric principles, such as factor analysis, reliability, validity, bias, test-construction and test-use. With self-assessment questions, further reading and a companion website including student and instructor resources, this is the ideal resource for anyone taking modules on personality and individual differences.

Individual Differences and Personality, Third Edition provides a comprehensive overview of research on personality. The book begins with the main approaches to the study of personality, 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 are life outcomes—such as relationships, work, health, and others—that are predicted by personality characteristics. The book additionally examines important individual differences, such as mental abilities, vocational interests, religious beliefs, political attitudes and sexuality. The third edition is updated with new findings on age-related differences in personality, on sexual orientation and personality, on socially desirable responding in personality assessment, and on the biological and social origins of mental ability differences. Treatments of several topics have been streamlined, including reliability and validity, developmental change, genetic and environmental influences and the structure of mental abilities. Organized by issues in personality research rather than by theorists Identifies main traits in personality and explains personality assessment Examines the impact of personality on life outcomes Explores developmental, genetic and evolutionary aspects of personality Includes other psychological characteristics (abilities, interests, beliefs and attitudes)

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.

Personality Differences and Biological Variations: A Study of Twins details a study aimed to discover the genetic uniqueness of twins and the biological basis of their individual differences. Coverage of the book includes the details of the project – its aims, method, its theoretical background, sample selection and the description of the sample; personality traits in twins the sociability/impulsivity and the Foulds hostility scale; and the influence of age and separation. The book also covers some aspects of cognitive function in twins – divergent thinking and the analysis of its measures; conceptual thinking; and the relationship of personality and cognitive function. The book also includes twins' physiological measures; their sedative drug tolerance; and a nervous typological analysis of their personal variaton. The text is recommended for psychologists who wish to learn more and study about how twins think and how they get along with one another.
