The use of latent image printing in problem solving and self-assessment exercises

Abstract

Latent image printing is a technique whereby information is printed which is invisible until treated by the reader in some way, for example by rubbing a special pen over the area. This technique has applications in medical education, particularly in self-assessment and patient-management problem exercises. It is superior to other methods of providing feedback in so far as feedback can be selective and in a form that discourages the reader from looking at the answer before attempting the question.
