Dimensions Of Personality by Hans Jürgen Eysenck

This book argues that individual differences in behavior can be reduced to a small number of measurable, biologically rooted dimensions—most notably extraversion–introversion and neuroticism–stability—and develops a psychometric and theoretical framework for identifying and measuring these traits. It presents factor-analytic evidence and reviews genetic, physiological, and conditioning studies to link personality dimensions to nervous-system functioning and arousal, and discusses the implications of a dimensional approach for assessment, research, and clinical practice.
