Teaching About Systemic Ethical Misconduct Increases Awareness of Ethical Principles: A Replication and Extension of Grose-Fifer’s (2017) Tuskegee Role-Play Activity

Background: Introductory Psychology students rarely learn about unethical biomedical research outside the Tuskegee syphilis study, but these practices were widespread in U.S. public health research (e.g., at the Willowbrook State School researchers infected children with disabilities with hepatitis). Objectives: Replicate and extend Grose-Fifer’s research ethics activity by evaluating if an online homework and in-class role-play increased awareness of unethical research and abuses at Tuskegee (replication) and Willowbrook (extension) and subsequent changes in human subjects protections. Method: As homework, students read about the studies and wrote statements from perspectives of individuals involved. In class, students read their statements and discussed how outrage led to research conduct regulations. Online pre/posttests asked students why it was important to learn about both studies. Results: At posttest, students were more aware of unethical research at Willowbrook and that Tuskegee led to changes in human subjects protections. Students who completed the role-play activity were less likely to mention abuses for Tuskegee than students who did not participate. Conclusion: We were partially successful in replicating and extending Grose-Fifer. Teaching Implications: Research ethics instruction should draw attention to historical precedents and how public outrage and social activism led to increased protections for research participants.

Teaching Engineering Ethics Through a Psychology Course

While ethics instruction is now widespread, studies are still looking for different ways to integrate ethics in engineering programs. In this article, we propose a novel approach by teaching engineering ethics through a psychology course. Starting with the relevant literature studies, we have argued that the phenomeno-logical experience of ethics is a source to explain psychological truths, while en-gineering ethics can be better taught from psychological / behavioral perspectives. A pedagogical approach of experiential learning has been applied to integrate engineering ethics into the psychology course. The empirical study with 400 stu-dents in psychology courses show that teaching engineering ethics through a psychology course has a significant effect on improving the knowledge of engi-neering ethics for students. The relationship between the two pre- and post-test scores was a strong positive linear relationship. A regression equation with a slope of a straight line of 0.57 and a constant of 1.52 has been provided to predict the improvement of post-test scores through pre-test scores. This study proposes the formation of a "psychology and ethics" module in technical schools.
