Experimental Psychology, Volume 4: Personality and Arousal: A Psychophysiological Study of Psychiatric Disorder describes a series of overlapping studies carried out over a number of years and using a very wide variety of experimental techniques in both neurotic and psychotic patients. This book is composed of nine chapters. The first five chapters are concerned with neurosis, especially with the detailed examination of Eysenck's theory of dysthymia-hysteria. The succeeding two chapters explore some exploratory studies of psychosis looked at from a similar psychophysiological viewpoint. The remaining chapters propose a theory of psychiatric disorder and some of the implications of this theory for the study of problems in the field of personality that are not directly tackled n previous chapters. This book will prove useful to psychologists, psychiatrists, and research workers who are interested in the field of personality.

Qualitative evaluations of buccal smear specimens have indicated an unusually high incidence of triple-X females in a hospitalized schizo phrenic population. Specimens from adult prisoners have also indicated an unusually high incidence of triple-X females. Studies of a population of confined juvenile offenders, on the other hand, have indicated an unusually high incidence of one-X females. No unusual indications were observed in a population of "normal" volunteer females. The data and their implications are discussed in context with previous observations. ACKNOWLEDGMENTS This study was made possible primarily by research grants from the Scottish Rite Committee on Research in Schizophrenia, The National Association for Mental Health, Inc. Additional support was provided by a grant from the National Institutes of Health, GRS-05563. The study has been supported by the State of Ohio, Department of Mental Hygiene and Correction, Division of Mental Hygiene. The author is particularly indebted to Edward N. Hinko, M.D., Regional Director of Research, whose advice and help made the present study possible.

Psychophysiology is an ever expanding field. The application of psychophysiological investigations to psychiatric disorders is likewise expanding and has in fact shed much light on some of the neural processes contributing to the development of psychiatric symptoms and/or their amelioration following treatment. In the first part of this volume, we have selected a number of conditions where psychophysiological investigations have recently provided some insight into the pathophysiology of a particular manifestation (e.g., dissociation) or a disorder. Although this volume has a main focus on electrophysiological investigative modalities where neuroimaging was complimentary this added insight was included. The second part of the volume focuses on novel uses of psychophysiological measures, combining it with neuropsychology and imaging where possible, in the context of neuropsychiatric research and describes advanced analytical tools. Both basic and clinical investigators in this field should find the reviews and interpretations provided clear and informative. Clinicians will find this volume easy to assimilate. While direct clinical applications may be down the road, the insights provided should help the practicing clinicians to have firmer understanding of the complexity of the disorder they manage in everyday practice.
