Forums IMPORTANT: PLEASE READ PhotoReading, Memory Optimizer Perceptual Defenses and Repression Mechanisms

On Page 39 of the PhotoReading (PR) course manual there's an illustration which illustrates the PR process, including Input, Process and Output. The illustration also mentions Perceptual Defenses (PD) and Repression Mechanisms (RM.) Do any of you know more about these two areas - PD + RM, and can you recommend any books which will explain these concepts and the other concepts on the illustration further?

Thanks,

Gary
