What is the 'ortho effect'?
- This phenomenon is termed the ‘ortho effect’, and is well- documented [17-28]. Interactions of vicinal groups in the M+. of various derivatives of substituted benzoic acids initiate various types of hydrogen and skeletal rearrangements, and generate multiple fragmentation processes. As a result, for

What are the effects of orthographic processing?
- However, the most obvious impact is on the writing, the speed of writing, and the spelling of words. Those with orthographic processing issues have difficulty remembering sight words; they tend to guess words incorrectly. Orthographic processing issues are the brain's inability to retain simple words and sight words to recall when reading.
