Researchers often use the Vividness of Visual Imagery Questionnaire (VVIQ) to assess mental imagery. This 16-item test asks respondents to think of a scene or a person and, in each case, rate the vividness of what they see. The lower the final score, the weaker a person’s mental imagery. In the quiz below, you can complete one example from the questionnaire and find out how your mental imagery stacks up. Try to imagine each scene and then rank how vivid the image is.
