Mental representations are internal cognitive symbols that stand for external reality. They help individuals process and understand information by creating a mental image or concept of objects, events, or ideas. For example, when thinking about a dog, a person may visualize its appearance, behavior, and characteristics, allowing them to recognize and categorize it. These representations can take various forms, including visual images, sounds, or abstract concepts. They play a crucial role in memory, problem-solving, and decision-making, enabling people to navigate their environment and interact with the world effectively. Understanding mental representations is essential in fields like psychology and cognitive science.
