What is the long-term memory definition in terms of information retrieval?

The definition of long-term memory in terms of information retrieval emphasizes the encoding and storing of information for future retrieval. This process involves taking information from short-term memory and organizing it so that it can be easily accessed later. In long-term memory, information is stored durably and can be retrieved when needed, often influencing behavior and knowledge over extended periods. This characteristic is crucial for the formation of memories and allows individuals to use previously learned information in various contexts.

The other options focus on specific aspects of memory that do not encompass the overall process of long-term memory. For instance, the ability to recall information based on rehearsal highlights a specific method of strengthening memory but does not capture the broader definition. Similarly, knowledge retention without active recall refers to passive storage, which is limited and doesn't represent the structured nature of long-term memory. Lastly, the decay of memories pertains to forgetting rather than the active process of storing information, which is central to the definition of long-term memory.
