A Psychologist’s Work with a Resident of the Jail

Discuss the research methods of a psychologist working with a resident of the local jail.

Maxim is working with Joaquin in a counseling situation. Joaquin is a resident of the local jail, having been found stealing pastries from a bake shop. When caught, Joaquin claimed that the devil told him to do it and that he had done far worse things in the past. Maxim visits him and makes notes about what he learns about Joaquin each time they are together. Which research method was used? What ethical guidelines would need to be followed to conduct this study? Which basic ideas behind early approaches in psychology most closely align with this method?
