Which term is the science of behavior and human thought processes?

• A. Psychology
• B. Documentation
• C. Integrity
• D. Grammar

Answer: (A)

The main idea being tested is which field is the scientific study of how people behave and what they think. Psychology is that field. It’s defined as the scientific study of behavior and mental processes—things like thoughts, memories, emotions, perceptions, and the ways these interior experiences influence actions. Psychologists use careful observation, experiments, and systematic methods to understand why people act the way they do and how their minds work, across areas from learning and memory to mood and social interaction. The other terms point to different domains: documentation is simply recording information, integrity refers to moral principles and consistency, and grammar deals with the rules of language. While those areas can involve people, they aren’t described as the science of behavior and thought processes in the same way psychology is.
