Research Methods - Ethics Pt1 - History of Research Ethics

The Importance of Ethical Principles in Human Research

Historical Context and Ethical Failures

• Many ethical principles in research stem from historical failures, often involving dehumanization or neglecting human costs for scientific truth.

• Post-World War II revelations about Nazi experiments on humans highlighted the need for strict ethical standards in research.

Examples of Inhumane Research Practices

Nazi Experiments

• The Luftwaffe's hypothermia studies involved non-consensual experiments on prisoners, leading to severe suffering.

• Horrific methods included causing wounds intentionally to test treatments like sulfonamide without consent.

Tuskegee Syphilis Study

• Conducted by the U.S. Public Health Service, this study misled poor Black sharecroppers into believing they were receiving treatment while actually observing untreated syphilis over 40 years.

• Participants were not informed of their condition and received placebos instead of effective treatments like penicillin, resulting in numerous deaths and infections among spouses and children.

Consequences and Legal Reforms

• A leak about the Tuskegee study led to the Belmont Report, establishing legal protections for human subjects in research.

• Official apologies from the U.S. government came decades later, highlighting ongoing issues with accountability in research ethics.

Additional Disturbing Studies

The Monster Study

• This speech pathology study at the University of Iowa used orphans as participants without their knowledge, leading to psychological harm through negative reinforcement.

Understanding Attachment Theory and Its Historical Context

The Evolution of Parenting Advice

• Treatments for stuttering are discussed alongside Harry Harlow's studies on attachment theory, which were primarily conducted with monkeys.

• In the 1930s and 40s, behaviorism influenced parenting advice, promoting classical and operant conditioning techniques to manage children's behaviors.

• Popular advice suggested minimizing physical contact with infants to avoid spoiling them, leading to practices that discouraged comforting crying babies.

The Role of Caregivers in Infant Development

• John Watson's controversial views included advising against hugging or kissing infants, advocating for minimal physical interaction.

• There was significant debate regarding the mother's role; it was commonly believed that attachment stemmed from nourishment rather than emotional security.

Harlow's Groundbreaking Research

• John Bowlby challenged existing beliefs by proposing that infants form emotional bonds with caregivers based on security rather than just food sources.

• Harlow’s experiments involved separating newborn monkeys from their mothers and offering them surrogate "mothers" made of different materials—one providing food and another comfort.

Findings on Comfort vs. Nourishment

• Monkeys showed a preference for the comfort-providing surrogate over the one that offered food, highlighting the importance of contact comfort in developing attachments.

• Harlow demonstrated that a secure base is essential for exploration and returning when scared, contradicting earlier psychoanalytic assumptions about maternal roles.

Ethical Implications of Research

• Harlow's work revealed severe psychological issues in monkeys subjected to social deprivation, emphasizing the critical need for physical contact in infant development.

• Despite ethical concerns surrounding his methods, Harlow’s findings led to improved treatment policies for infants in orphanages and hospitals.

Impact on Modern Research Ethics

• The historical context illustrates how research can lead to beneficial changes despite initial harm; it raises questions about moral responsibilities in scientific inquiry.
