Final answer:
You are using the memory technique known as chunking when combining separate items of information into larger, more manageable units. This technique helps facilitate memory retention by breaking down complex information into simpler groups or 'chunks.'
Step-by-step explanation:
If you combine separate items of information into large units and then remember these larger units rather than individual items, you are using chunking. Chunking is a technique where you organize information into manageable bits or chunks, making it easier to remember. An example of this could be memorizing a phone number by dividing it into smaller groups of numbers rather than trying to remember one long string of digits.
Other techniques mentioned, such as elaboration and rehearsal strategies like maintenance rehearsal and distributed practice, play different roles in memory. Maintenance rehearsal involves repeating information over and over to keep it in short-term memory, potentially moving it to long-term memory, while distributed practice refers to spreading study sessions over time to help with memory consolidation. Elaboration includes connecting new information to existing knowledge to make it more memorable.
