I have relied on the Marketing Scales Handbooks over several years in academic and industry roles and look forward to using the newest edition. A seven on a seven-point satisfaction scale!
Imagery Vividness (Visual)
Sixteen, five-point Likert-type items are used to measure the clarity of mental images a person evokes. The scale measures a person's general visual imagery ability rather than the clarity of a particular stimulus under investigation. The scale has been referred to by several users as the Vividness of Visual Imagery Questionnaire (e.g., Childers 1985; Marks 1973).
