In any research study on the mind, or on behaviors, one has to be wary of such ethic and moral codes. These moral codes can often times be within the jurisdiction of the city, the state or even the federal law. Be aware of these rules, and resolve the issue with local committees. You also have to remember that who you are working on is a problem. For instance, if you were researching, "How does a human react when his arm is cut off" that would be highly immoral.
The APA codes i reference are; Principle A and 1.02
