Elaborative rehearsal involves making information more meaningful by connecting it with existing knowledge or creating associations. This process enhances memory retention and recall by adding depth to the information.
145
What is chunking?
Chunking is a memory technique where information is grouped into smaller, more manageable units or "chunks." This method helps increase the capacity of short-term memory and makes it easier to recall larger amounts of information.
