What is a key feature of long-term memory capacity?

Long-term memory is characterized by its vast storage capacity, which is often described as being very large without obvious limits. This feature allows individuals to retain an immense amount of information over extended periods, ranging from facts, experiences, skills, and more, across a lifetime. Unlike short-term memory, which has more restricted capacity—such as the often-cited limit of around seven items in active memory—long-term memory can store an indefinite amount of information.

The content can include everything from historical events to personal memories, and while the retrieval of information may sometimes be challenging, the actual capacity for storage in long-term memory is considered to be nearly limitless. This property is crucial for learning and memory retention, making the concept of a large, undefined capacity foundational within cognitive psychology.
