Memory Test

The document discusses the concept of chunking as it relates to memory. It explains that George Miller proposed that humans can only retain about 7 items in short-term memory but can boost retention by grouping items into larger categories or chunks. This process of chunking information into a hierarchical schema allows the brain to efficiently store and retrieve large datasets. The document then provides an example where a string of random numbers is harder to memorize than when they are grouped into meaningful date ranges, demonstrating how chunking aids long-term memory.
