Final answer:
The DSM has a biological perspective, cognitive psychology studies human thinking, and a researcher focused on job suitability is likely a personality psychologist.
Step-by-step explanation:
The Diagnostic and Statistical Manual of Mental Disorders (DSM) is best described as having a biological perspective. This manual serves as a guide for clinicians in the diagnosis of mental disorders and emphasizes the biological underpinnings of these conditions, including genetic, brain structure, and biochemical factors.
The field of cognitive psychology focuses on the study of human thinking, specifically looking at how we process, store, and use information.
A researcher interested in what factors make an employee best suited for a given job would most likely identify as a(n) personality psychologist, as they would study personality traits and how they influence job performance and suitability.
