Explanation:

Around the turn of the twentieth century, graduates of psychology at Cornell University in Upstate New York were asked to swallow a rubber tube to perform psychological research.

Through providing data on the experience to research the responsiveness of their internal organs, Professor Edward Bradford Titchener had his students conduct a process of introspection.

At the time, the study became well known around Cornell, bringing a reputation as an unethical location to the psychology laboratory.
