What does psycholinguistics study?

• A. Language with experiments
• B. Animal signaling
• C. Numerical cognition
• D. Artificial languages

Answer: (A)

Psycholinguistics investigates how people understand, produce, acquire, and process language—the mental operations that support speaking, listening, and reading. It examines how words and grammar are stored in memory, how we plan sentences, and how we parse language in real time, often by using experiments that measure reaction times, accuracy, eye movements, or brain activity to reveal the underlying processes. Because of this emphasis on language and empirical study of human behavior, it aligns with examining language through experiments. The other topics target different areas: animal signaling explores communication in nonhuman species, numerical cognition focuses on thinking about numbers, and artificial languages deals with constructed languages rather than natural human language processing.
