t the animals well being is a major concern in the conducting of the experiment (APA, 2001). Once the research has been deemed necessary for scientific benefits, now the next step is to acquire animals for the experiment. According to the APA ethical principles, animals may not be bred by the researcher for the experiment, but must be acquired lawfully. If an animal is captured from the wild, it must be done in a humane way. When transporting the animal, proper conditions should include adequate feeding, water, ventilation and space and should not impose stress to the animal. Experiments involving endangered species require a permit be obtained from the Fish and Wildlife Service. These are only used as a guideline, any actions should be in compliance with any Federal regulations (APA, 2001). Currently, there are no specific guidelines by the APA when it comes to care and housing of the animals. This issue has been part of an ongoing debate between the APA and the USDA. The USDA views psychological well being as a concept, while the APA finds it is too complex to define (APA, 2001). In this case, the APAs ethical principles for care and housing are on a case by case basis and are determined by a researcher who is familiar with the species uses judgement in determining the well being. Additionally, housing facilities are to meet requirements by the USDA, inspected twice a year, and are under committee review (APA, 2001). The ethical principles include an extensive section related to experimental procedures on the animals. Outlined are different scenarios the animal may go through when part of an experimental procedure. Studies that do not result in distress to the animals are acceptable. When necessary, research that minimizes discomfort should be used. Psychologists are encouraged to test painful stimuli on themselves whenever possible. If the procedure results in intensive pain or the animal is exposed to prolonged i...
