The term "alternative medicine" describes healing practices that are used in place of conventional "Western" medicine. Alternative medicine often rejects science-based medicine and includes therapies that developed out of religious and cultural traditions. Examples are naturopathy, herbalism, meditation, biofeedback, hypnosis, homeopathy, and nutritional-based therapies. Advocates of alternative medicine believe that the various alternative methods are more effective than conventional medicine in treating a wide range of medical conditions. Dissatisfaction with conventional medicine leads many people to seek alternative therapies. Some people choose alternative medicine because they do not trust traditional authority figures, such as the physician, or they dislike the current delivery methods of scientific medicine, particularly the over-reliance on synthetic drugs. Some patients prefer alternative therapies because they are averse to the painful or dangerous side effects of biomedical treatments. The majority of alternative medicine users find health-care alternatives to be more in agreement with their own values, beliefs, and philosophy about health. Many have a holistic orientation to health, a belief that the body, mind, and spirit are connected. To meet the growing demand for alternative treatments, a variety of schools and colleges offer courses in alternative medicine. Even conventional medical colleges have started offering courses. Most alternative medicine programs take a holistic approach to health that explores the interconnection between the mind and body. Mind-body medicine works under the premise that the mind can affect bodily functions and symptoms. Other alternative medicine programs emphasize the study of substances found in nature such as herbs, foods, vitamins, and minerals. Now listen to the recording.

Psychology is a natural science that describes and explains the physiological and sensory aspects of human behavior. It studies the causes, conditions, and immediate consequences of sensations and emotions. Psychologists view the human mind as a function of the brain. Thought is a result of chemical and mechanical laws that govern brain action. All human cognition is the result of physiological processes that can be observed and measured. A variety of computational models provide tools for studying the functional organization of the mind. Because psychology is a natural science, it is based on objectively verified facts and the application of the scientific method. Psychologists conduct controlled experiments in a laboratory in order to support their basic assumptions and develop theories. Experimenters use several types of measurements, such as rate of response, reaction time, and level of neural activity in various areas of the brain. Psychologists use inductive methods to derive general principles from specific facts. They aim to acquire a body of facts and laws about the human mind. Psychology has a number of related subfields, all of which are primarily concerned with the biological bases of behavior and mental states. For example, behavioral neuroscientists use animal models, typically rats, to develop theories about the neural and cellular mechanisms of human behavior. Cognitive neuroscientists study the neural aspects of psychological processes in humans. Neuropsychologists study specific aspects of mental impairment caused by brain damage or disease.

Research has taught us a lot about job satisfaction and the motivation of workers. First, workers are more motivated if their job offers a sense of community. A sense of community grows when workers get recognition for their accomplishments and when they believe their skills are being well used. Social organization in the workplace is important. Supervisors and co--workers have a tremendous influence on job satisfaction. When workers are asked what they like or do not like about their job, around 80 percent will mention the people they work with. Second, while workers value traditional economic incentives such as pay and promotions, they also have needs and expectations that go beyond economic concerns. Workers need a sense of security in the workplace. Security comes from confidence in the system that they are part of, the quality of the product or service they provide, and the reputation of the company. Security comes from the personal satisfaction of knowing that their skills are being utilized in a way that contributes to the company’s success. Third, the most satisfying jobs are those with a high level of autonomy, in which employees can make their own decisions about the pacing and sequence of work with minimal supervision. Job autonomy is most often found in high-pay and high-prestige occupations. In jobs in the middle or lower levels of pay and prestige, workers generally have less autonomy. The lower the occupational status, the more heavily supervised the workers are, and the fewer decisions they can make on their own. Now listen to the recording.
