"Twenty male undergraduate volunteers worked on a simple vigilance task without interruption for 1 3/4 hours in noise (112.5 db SPL) and 1 3/4 hours in quiet (79 db SPL). The performance function was the typical one found in such tasks; performance dropped off rapidly after an initial high level. There was no differentiation, however, between performance in the noise session and in the quiet session. This result, which differs from previous results at this and at other laboratories on effects of noise on “vigilance", is explained on the basis of the absence of a need for flexibility of attention for performance on the simple “vigilance” task used here and the presence of such a need for performance on “vigilance” tasks in which an effect of noise was found."--Abstract.

"Nine volunteer male undergraduates with normal hearing were required to monitor three clocks simultaneously, and to respond when a clock hand made a double jump (about once a minute for each clock). During a two-hour control session in quiet (83 db) no significant changes in performance level occurred. During another two-hour session in which the noise level was raised to 114 db after the first half hour, the subjects' performance was not changed significantly until the final half hour of work. At that time performance in the noise session became significantly worse. These results support conclusions based on other types of monitoring tests, that performance involving vigilance suffers under noise stress. They do not confirm findings of other laboratories that a monitoring task worked at for two hours in relative quiet will show measurable performance decrements."--Abstract.

Vigilance: The Problem of Sustained Attention deals with vigilance and how the ability to sustain attention is influenced by certain definite conditions of the external and internal environment. Topics covered range from factors affecting vigilance performance to the physiological correlates of vigilance, theories of vigilance performance, and the relationship between arousal and vigilance performance. This volume is comprised of six chapters and begins with an overview of research on vigilance behavior, followed by a discussion on some of the factors affecting vigilance performance, including signal frequency and personality. Subsequent chapters explore physiological correlates of vigilance such as galvanic skin resistance and cortical evoked potentials; reinforcement theory, expectancy theory, and other theories of vigilance performance; and arousal theory and the phenomenon of time error. The final chapter considers some of the conditions that improve vigilance performance, along with the correlation between vigilance and arousal. This book will be of interest to psychologists.

This volume contains the proceedings of a symposium held in St. Vincent, Italy, on August 3-6,1976, entitled "Vigilance II: Relationships Among Theory, Physiological Correlates, and Opera tional Performance." The symposium was sponsored jointly by the Human Factors Panel of the Scientific Affairs Division of NATO and by the Physiology Programs Office of the U.S. Office of Naval Research (Contract N00014-76-C-0722). These sponsorships, and the helpful assistance of Dr. Donald P. Woodward and Dr. John A. Nagay, are gratefully acknowledged. Following the editor's introduction, the papers appear in the order they were given at St. Vincent. In general they are grouped according to the main topical themes of the symposium: keynote ad dress, vehicle operation, monitoring and inspection, physiological correlates, stress effects, individual differences, and theoretical considerations. I must point out, however, that individual papers often overlapped several of these topical areas and thus no defini tive partitioning of the proceedings has been attempted. I wish to acknowledge the many contributions of my colleague, Dr. James O'Hanlon, to both the planning of the symposium and the preparation of the manuscript, and the invaluable role of my wife, Shirley Jean, in making the symposium such a pleasant one for all. In addition, I wish to recognize the countless contributions of Lynda Lee Chilton and Katherine Peimann whose performance in compos ing, typing, and proofing the manuscript is certainly a tribute to human vigilance, and endurance as well.

The investigation of a potential autonomic physiological concomitant of overt behavior (i.e., galvanic skin response as a correlate of signal detection) in a Mackworth-type vigilance task is described. Previous activity in this general area is discussed, and several new approaches are indicated.
