A memory aid using word association is referred to as?

A memory aid that uses word association is referred to as a mnemonic device. Mnemonics are techniques designed to help remember information through the use of patterns, letters, or associations, leveraging the brain's natural ability to remember vivid images or connections. This technique can be particularly useful in situations where information is complex or requires memorization of lists, such as terms related to barbering or beauty industry standards.

By employing a mnemonic device, an individual may create an acronym or a phrase that represents the initial letters of the items they wish to remember, making recall easier. For example, in the context of barbering, a mnemonic could help students remember the steps in a particular haircut or the names of tools used.

The other options do not represent this specific technique. A synonym refers to a word that has the same or similar meaning as another word but does not serve as a memory aid. A formula typically involves a mathematical or systematic method for solving problems, while a glossary is a list of terms with definitions, which is more of a reference tool rather than a device for memory enhancement.
