The Logo Reading System is a teaching method for all ages. It was developed by Marcia Braden, PhD, a leading expert in FXS and ASD. It has proven to be especially effective with individuals who have Spectrum Disorders such as Autism and FXS. This method uses high strength stimuli to hold attention while teaching reading. The Logo Reading System method works because it capitalizes on "incidentally acquired knowledge" and does not require direct instruction. This create an innate interest that promotes engagement and fun while learning to read.
