What describes long-term memory?

• A. Capacity: 3-7 chunks, Duration: 0.5-3 seconds
• B. Capacity: Infinite, Duration: Permanentish
• C. Capacity: 4-7 chunks, Duration: 5-15 seconds
• D. Capacity: 5-9 items, Duration: Temporary

Answer: (B)

Long-term memory is characterized by its capacity and duration. It is known for having a virtually limitless capacity, allowing individuals to store an extensive amount of information over time. This is in stark contrast to short-term memory, which has much more limited capacity, typically involving only a few chunks of information and a brief duration of retention.

The duration of long-term memory is often described as "permanentish" because, while memories can theoretically last a lifetime, they can also be forgotten or become less accessible over time. This ability to retain information for extended periods is crucial for learning and personal development.

The other options reflect characteristics more closely associated with short-term or working memory, which has significantly reduced capacity and duration compared to long-term memory. Thus, the defining features of long-term memory—its expansive capacity and lasting duration—make the selected answer the most accurate representation of this concept.
