Research ethics in psychology.

To advance knowledge about human behavior, individuals in the field of psychology conduct research. Such endeavors involve both human and nonhuman participants. The use of nonhuman participants is usually understood to mean that there will be animal testing in the research. With either type of participant, lawful conduct and efforts to protect the welfare of the research participants are always of the utmost concern. The field of psychology, through the work of the American Psychological Association (APA), has devised a set of general ethical principles that apply to research to protect the participant and the data, or information, derived from such work.
