What technique best describes using a memorable physical characteristic to recall a name?

The technique that best describes using a memorable physical characteristic to recall a name is association. This method leverages the process of linking new information, such as a person's name, with something familiar or easily memorable, which in this case is a distinctive physical trait. By creating a mental connection between the name and the characteristic, it becomes easier to retrieve the name later. This associative memory technique enhances recall because it taps into existing knowledge or cues to facilitate memory retrieval.

In cognitive psychology, associations are crucial for enhancing memory, as they allow us to create networks of information that can trigger recall through interconnected ideas or experiences. This approach is effective in everyday scenarios, where visual or sensory details can aid in remembering names or other information by establishing a mental "hook."
