Abstract
This research traces and examines specific examples of the application of model organisms during the experimentation of biomedical sciences and psychology. The main purpose of the study is to compare how scientists utilize animal models for experiments with specific cases of humans who were used as test subjects, focusing on methodologies and main motivations. A core question that motivated this work is: Can we use the term ‘‘model organisms’’ to refer to human beings? In other words, can human beings be considered analogue models, specifically model organisms? This study will try to respond to the above question, by drawing upon theoretical frameworks and definitions from the field of philosophy of science, particularly focusing on the concepts of the analogue model, model organisms, and animal model. It will also analyze specific examples of experimental utilization of animal models, such as Hippocratic physicians’ experiments involving goat brains, Galen's experiments on a pig during the Greco-Roman period, and the utilization of guinea pigs in modern scientific research. Finally, the study will examine historical examples where humans were used as test subjects including the Nazi medical experiments during World War II and the Stanford prison experiment conducted by psychology professor Philip G. Zimbardo.
