Final answer:
The guest speaker with 'PsyD' next to her name indicates that she is most likely a clinical or counseling psychologist, focused on therapy rather than research.
Step-by-step explanation:
The guest speaker with 'PsyD' written next to her name is most likely a clinical or counseling psychologist. The PsyD, or Doctor of Psychology, is a professional doctoral degree intended for psychologists who wish to work in clinical settings, focusing more on providing therapy and treatment than on research. This degree prepares individuals to engage in the practice of psychology and administration of various psychological assessments, rather than emphasizing the creation of research like a PhD might. Both clinical psychologists and psychiatrists can provide therapy, but their training and roles differ significantly, with psychiatrists having a medical degree and the ability to prescribe medication.
