The Effects of Progressive Relaxation and Music on Attention, Relaxation, and Stress Responses


Book Description

Stress management interventions have been shown to be effective adjuncts for the management of medical disorders, and for the prevention and management of occupational stress. Despite their usefulness, it is not completely understood how behavioral stress management techniques exert their effects. Benson (1975) proposed that all relaxation techniques elicit a general "relaxation response." Davidson and Schwartz (1976) suggested that stress management techniques have specific effects A compromise position suggests that the specific effects of relaxation techniques are superimposed upon a general relaxation response (Lehrer AND Woolfolk, 1993). The cognitive behavioral model of relaxation suggests that relaxation is achieved through hierarchical cognitive and behavioral factors (Smith, 1988), but has not been adequately evaluated experimentally (Lehrer AND Woolfolk, 1993). The present experiment examined relaxation within a framework of the cognitive-behavioral model. Sixty-seven normal volunteers were exposed to a stress manipulation and then to one of two relaxation (Progressive Muscle Relaxation, Music) or control conditions (Attention Control, Silence). Measurements of attention, relaxation, and stress responses were obtained during each phase of the experiment. All four groups exhibited similar performance on behavioral measures of attention that suggested a reduction in physiological arousal following their relaxation or control condition, as well as decreased heart rate. Progressive Relaxation resulted in the greatest effects on behavioral and self-report measures of relaxation. The Music condition resulted in the lowest biological measures of stress (i.e., heart rate and cortisol responses).













Man-Machine-Environment System Engineering


Book Description

This book presents selected papers introducing readers to the key research topics and latest development trends in the theory and application of MMESE. The advanced integrated research topic man-machine-environment system engineering (MMESE) was first established in China by Professor Shengzhao Long in 1981, with direct support from one of the greatest modern Chinese scientists, Xuesen Qian. In a letter to Shengzhao Long from October 22nd, 1993, Xuesen Qian wrote: “You have created a very important modern science and technology in China!” MMESE primarily focuses on the relationship between man, machine and environment, studying the optimum combination of man-machine-environment systems, where “man” refers to people in the workplace (e.g., operators, decision-makers), “machine” is the general name for any object controlled by man (including tools, machinery, computers, systems and technologies), and “environment” describes the specific working conditions under which man and machine interact (e.g., temperature, noise, vibration and hazardous gases). The three goals of optimizing such systems are ensuring safety, efficiency and economy. Presenting interdisciplinary studies on the concepts and methods in physiology, psychology, system engineering, computer science, environmental science, management, education and other related disciplines, this book is a valuable resource for all researchers and professionals whose work involves MMESE subjects.
