Final answer:
Amy is most likely a clinical psychologist, as her role involves research into therapeutic techniques for psychological disorders, aligning with the functions of someone holding a PhD or PsyD in psychology.
Step-by-step explanation:
Amy, who holds a doctorate in psychology and has been hired by a teaching hospital to conduct research into effective therapeutic techniques for patients with acute psychotic disorders like schizophrenia, is most likely a clinical psychologist. Clinical psychologists have either a PhD or a PsyD and their work involves the diagnosis and treatment of psychological disorders as well as the development of therapeutic methods.
Unlike psychiatrists who have a medical degree (MD) and can prescribe medication, clinical psychologists focus more on therapy and counseling, and can administer and interpret psychological tests. Given Amy's research-focused role connected with a teaching hospital, her position aligns with the responsibilities of a clinical psychologist who not only contributes to academic literature but also to clinical practice innovations.
