a problem and through the identification of the said problem, discovering a solution. Therefore, it is necessary for environmental psychology to be problem-oriented. One important aspect of a problem-oriented field is that by identifying problems, solutions arise from the research acquired. The solutions can aid in making society function better as a whole and create a wealth of knowledge about the inner workings of societies. Environmental psychologist Harold Proshansky discusses how the field is also "value-oriented" because of the field's commitment to bettering society through problem identification. Panyang discusses the importance of not only understanding the problem but also the necessity of a solution. Proshansky also points out some of the problems of a problem-oriented approach for environmental psychology. First, the problems being identified must be studied under certain specifications: they must be ongoing and occurring in real life, not in a laboratory. Second, the notions about the problems must derive directly from the source – meaning they must come directly from the specific environment where the problem is occurring. The solutions and understanding of the problems cannot come from an environment that has been constructed and modeled to look like real life. Environmental psychology needs to reflect the actual society, not a society built in a laboratory setting. The difficult task of the environmental psychologist is to study problems as they are occurring in everyday life. It is hard to reject all laboratory research because laboratory experiments are where theories may be tested without damaging the actual environment or can serve as models when testing solutions. Proshansky makes this point as well, discussing the difficulty in the overall problem oriented approach. He states that it is important, however, for the environmental psychologist to utilize all aspects of research and analysis of the findings and to take into account both the general and individualized aspects of the problems. Environmental psychology addresses environmental problems such as density and crowding, noise pollution, sub-standard living, and urban decay. Noise increases environmental stress. Although it has been found that control and predictability are the greatest factors in stressful effects of noise; context, pitch, source and habituation are also important variables [3]. Environmental psychologists have theorized that density and crowding can also have an adverse effect on mood and may cause stress-related illness or behavior. To understand and solve environmental problems, environmental psychologists believe concepts and principles should come directly from the physical settings and
