What are strategies that enhance memory through methods like categorization and acronym creation called?

The correct answer is mnemonic techniques, as these are specific strategies designed to enhance memory retention and retrieval through the use of various aids. Mnemonic techniques encompass a variety of methods, such as categorization, which involves grouping information into related categories to make it easier to remember, and acronym creation, where the first letters of a series of words are combined to form a memorable word or phrase. These techniques leverage the brain's natural inclination to remember structured information or recognizable patterns, thereby improving recall.

In contrast, constructivist approaches focus on how learners actively engage with and build their own understanding of information, rather than on memory strategies tailored explicitly for recall. Maintenance rehearsal refers to the cognitive process of repeatedly verbalizing or thinking about information to maintain it in short-term memory, but it doesn't include the creative methods involved in mnemonic devices. Interference theory relates to the impact of other information on memory retrieval, which is not directly tied to the use of memory-enhancing techniques like categorization and acronyms.
