Researchers may study the effects of privilege upgrades awarded by the prison.
Explanation:
The researchers can conduct the research with prisoners in a certain rule circle and this research is governed by the federal regulations that classify inmates as susceptible populations because their capacity to make an informed and self-decision to become a part in research is negotiated.
Some forms of research with prisoners are allowed, but often require recheck and approval from multiple agencies. The IRB should be contacted during the design of any research norms expected to associated inmates.
