As a ___ the psychologist studies learning so that he can know more and more about it. (a) Historian (b) Geographer (c) Scientist (d) Sociologist ✅ Correct Option: (c) Scientist Explanation: A psychologist approaches the study of learning as a scientist, using systematic, empirical, and experimental methods to understand human behavior and mental processes. Unlike a historian who studies the past, a geographer who studies land and environment, or a sociologist who studies society, a psychologist applies scientific investigation to observe, measure, and analyze learning processes. This scientific approach allows for reproducibility, reliability, and validity in research, distinguishing psychology from philosophy or general speculation. Modern educational psychology relies heavily on scientific methods to optimize teaching strategies, learning environments, and student outcomes, making this concept central for PPSC exams. 10 PPSC-Relevant Facts: 1.
