What is the main function of long-term memory?

  1. To store immediate, sensory information

  2. To help recall information quickly

  3. To retain information for extended periods

  4. To facilitate short-term decision making

The correct answer is: To retain information for extended periods

The primary function of long-term memory is to retain information for extended periods. This memory system allows individuals to store and access vast amounts of information beyond the immediate present. Long-term memory is essential for learning, as it enables the retention of facts, experiences, skills, and knowledge that can be called upon when needed. It contrasts with short-term memory, which is more focused on temporary storage for immediate tasks. This long-lasting nature of long-term memory is crucial for developing a coherent understanding of the world and supports various cognitive functions, including problem-solving and decision-making over time.
