Dr. Samuel T. Orton coined the term "strephosymbolia" to describe a condition that affects one's ability to read due to difficulties with recognizing and interpreting symbols, particularly letters, in a specific arrangement. This concept highlights how the brain processes written language and how it may confuse the arrangement of symbols, leading to challenges in reading. The term directly addresses the visual and cognitive aspects of processing letters and words, which is foundational to understanding dyslexia and other reading challenges.

The other terms, while related to reading difficulties, do not specifically capture the unique implications of symbol arrangement that Orton was addressing. "Word blindness" generally refers to an inability to recognize words but does not encompass the broader conceptualization of symbol confusion and arrangement. "Dyslexia" is a more modern term that is widely used today to describe language processing difficulties but did not originate with Orton. "Acquired blindness" is not specifically related to the symbolic processing of letters and words, which is central to Orton's concept of strephosymbolia.
