This document provides a word of caution for a memory and learning course. It explains that the course requires participants to use their imagination to form vivid mental images to remember words. While imagery can be creative, the human mind also naturally thinks of things that are violent, gross or offensive. The document warns participants that some words could unintentionally prompt inappropriate images and advises maturity and discretion when choosing images. It also reassures that no inappropriate content will actually be shown and encourages discussing any issues that come up.
