Define ethics As far as the definition of ethics is concerned, it revolves around general norms of behavior. This means that it can be used to differentiate between good and bad conduct. In this case, it can be evaluated in relation to some behavior which might be either acceptable or non-acceptable. When looked at from a psychological point of view, ethics can be termed as a procedure, method, or perspective. This means that they are aspects that ca be employed to ensure that people act in relation to specific policies and principles. In fact, they are codes that are always set aside by different organizations and more so professional associations where they will generally guide their conduct as they go about with their activities (Research Animal Resources, 2011, p. 9). It should be known that various codes have also tried to explain the whole aspect of animal care in relation to established ethical principles. In this case, good ethics (as far as researchers are concerned) should ensure that proper care and respect is given to animas whenever they are used in research. This means that there should be proper planning that will ensure that animal research is successful. Various organizations have been formed to conduct and guide animal research meaning that there should be good relations to uphold ethics. It should be known that there is a committee that deals with animal research meaning that it has established some guidelines. Most of these guidelines revolve around protecting the general interests for animals that will be used in research (Liao, 2010, p. 6). In fact, the psychological association has also established ethics which should be always adhered to when using animals. This means that psychologists should be fully aware of these guidelines. Values and ethics are very important in animal research and this is because results will benefit both humans and animals. Discuss the concept of risk/benefit ratio It is undeniable that animals have been used successfully to predict different outcomes. This is mostly in relation to data that will be found in different animal specimens. These aspects are life threatening acts which can explain why care is supposed to be taken. Results which might be obtained from the test of animals are not supposed to be transferred based on different model organisms. In a broad perspective, it can be said that risks that animals are exposed to should be balanced with other benefits that will be enjoyed by both humans and animals. Morals and good ethics should ensure that animals will not be exposed to any risks through proper experiments. Diseases commonly found in animal models differ with those ones found in human beings, and, this means that researchers should concentrate on aspects which might qualify to look like human diseases (Research Animal Resources, 2011, p. 2). The similarity of human beings and animals can be stressed upon based on models in relation to human psychology. In fact, different experiments can be questioned in relation to these similarities. Animals should not be exposed to inhuman treatment in the name of trying to discover something in relation to research. This is because the benefits that will be accrued or realized should not in any way justify mistreatment. J
