Final answer:
Uma is using the method of loci to remember her shopping list, which is a mnemonic device that associates items with locations to help transfer them to long-term memory.
Step-by-step explanation:
The technique Uma is using to remember a list of items by creating visual images of the items in various spots in her dorm room is called the method of loci. This is a powerful mnemonic device that enhances the memory by associating information with physical locations. It is part of a group of memory strategies useful for moving information from short-term memory to long-term memory. For example, picturing a loaf of bread on her desk to remember to buy bread helps Uma create a vivid and memorable mental image.
Other mnemonic devices include acronyms, acrostics, and jingles. Using acronyms, such as HOMES for the Great Lakes, or acrostics like "Please Excuse My Dear Aunt Sally" for the order of operations in math, can also enhance memory. Chunking, which involves organizing information into manageable bits, is beneficial for remembering sequences like phone numbers by grouping digits together into smaller units.
