Based on Eysenck's biopsychological trait theory, brain arousal has long been considered to explain individual differences in human personality. Yet, results from empirical studies remained inconclusive. However, most published results have been derived from small samples and, despite inherent limitations, EEG alpha power has usually served as an exclusive indicator for brain arousal. To overcome these problems, we here selected N = 468 individuals of the LIFE-Adult cohort and investigated the associations between the Big Five personality traits and brain arousal by using the validated EEG- and EOG-based analysis tool VIGALL. Our analyses revealed that participants who reported higher levels of extraversion and openness to experience, respectively, exhibited lower levels of brain arousal in the resting state. Bayesian and frequentist analysis results were especially convincing for openness to experience. Among the lower-order personality traits, we obtained the strongest evidence for neuroticism facet 'impulsivity' and reduced brain arousal. In line with this, both impulsivity and openness have previously been conceptualized as aspects of extraversion. We regard our findings as well in line with the postulations of Eysenck and consistent with the recently proposed 'arousal regulation model'. Our results also agree with meta-analytically derived effect sizes in the field of individual differences research, highlighting the need for large (collaborative) studies.

Fischer uses evolutionary psychology to explain why people's personality and values are both similar and different across cultures worldwide.

Zuckerman received his Ph.D. in psychology from New York University, Graduate School of Arts and Science in 1954 with a specialization in clinical psychology. After graduation, he worked for three years as a clinical psychologist in state hospitals in Norwich, Connecticut and Indianapolis, Indiana. While in the latter position the Institute for Psychiatric Research was opened in the same medical center where he was working as a clinical psychologist. He obtained a position there with a joint appointment in the department of psychiatry. This was his first interdisciplinary experience with other researchers in psychiatry, biochemistry, psychopharmacology, and psychology. His first research areas were personality assessment and the relation between parental attitudes and psychopathology. During this time, he developed the first real trait-state test for affects, starting with the Affect Adjective Check List for anxiety and then broadening it to a three-factor trait-state test including anxiety, depression, and hostility (Multiple Affect Adjective Check List). Later, positive affect scales were added. Toward the end of his years at the institute, the first reports of the effects of sensory deprivation appeared and he began his own experiments in this field. These experiments, supported by grants from NIMH, occupied him for the next 10 years during his time at Brooklyn College, Adelphi University, and the research labs at Albert Einstein Medical Center in Philadelphia. This last job was his second interdisciplinary experience working in close collaboration with Harold Persky who added measures of hormonal changes to the sensory deprivation experiments. He collaborated with Persky in studies of hormonal changes during experimentally (hypnotically) induced emotions. During his time at Einstein, he established relationships with other principal investigators in the area of sensory deprivation and they collaborated on the book Sensory Deprivation: 15 years of research edited by John Zubek (1969). His chapter on theoretical constructs contained the idea of using individual differences in optimal levels of stimulation and arousal as an explanation for some of the variations in response to sensory deprivation. The first sensation seeking scale (SSS) had been developed in the early 1960's based on these constructs. At the time of his move to the University of Delaware in 1969, he turned his full attention to the SSS as the operational measure of the optimal level constructs. This was the time of the drug and sexual revolutions on and off campuses and research relating experience in these areas to the basic trait paid off and is continuing to this day in many laboratories. Two books have been written on this topic: Sensation Seeking: Beyond the Optimal Level of Arousal, 1979; Behavioral Expressions and Biosocial Bases of Sensation Seeking, 1994. Research on sensation seeking in America and countries around the world continues at an unabated level of journal articles, several hundred appearing since the 1994 book on the subject.

Serves as a Festschrift for Hans J Eysenck on the occasion of his 80th birthday. Each chapter in this volume describes Hans Eysenck's contribution to a particular topic then what research has developed from it, what kinds of amendments, modifications or additions to his work are appropriate and, finally thoughts about the future of the field.

Research on personality psychology is making important contributions to psychological science and applied psychology. This second edition of The Cambridge Handbook of Personality Psychology offers a one-stop resource for scientific personality psychology. It summarizes cutting-edge personality research in all its forms, including genetics, psychometrics, social-cognitive psychology, and real-world expressions, with informative and lively chapters that also highlight some areas of controversy. The team of renowned international authors, led by two esteemed editors, ensures a wide range of theoretical perspectives. Each research area is discussed in terms of scientific foundations, main theories and findings, and future directions for research. The handbook also features advances in technology, such as molecular genetics and functional neuroimaging, as well as contemporary statistical approaches. An invaluable aid to understanding the central role played by personality in psychology, it will appeal to students, researchers, and practitioners in psychology, behavioral neuroscience, and the social sciences.

One of the major neuropsychological models of personality, developed by world-renowned psychologist Professor Jeffrey Gray, is based upon individual differences in reactions to punishing and rewarding stimuli. This biological theory of personality - now widely known as 'Reinforcement Sensitivity Theory' (RST) - has had a major influence on motivation, emotion and psychopathology research. In 2000, RST was substantially revised by Jeffrey Gray, together with Neil McNaughton, and this revised theory proposed three principal motivation/emotion systems: the 'Fight-Flight-Freeze System' (FFFS), the 'Behavioural Approach System' (BAS) and the 'Behavioural Inhibition System' (BIS). This is the first book to summarise the Reinforcement Sensitivity Theory of personality and bring together leading researchers in the field. It summarizes all of the pre-2000 RST research findings, explains and elaborates the implications of the 2000 theory for personality psychology and lays out the future research agenda for RST.
