Final answer:
A person with deep dyslexia would most likely read 'couch' instead of 'chair' due to semantic paralexia, which is a characteristic error where a word is replaced with another of similar meaning.
Step-by-step explanation:
A person who has been diagnosed with deep dyslexia is most likely to exhibit a reading pattern that involves semantic errors.
For example, they might read a word that has a similar meaning to the intended word but is incorrect in the specific context.
Therefore, the correct answer from the provided options is that a person with deep dyslexia would be most likely to read "couch" instead of "chair."
This is because both words are related in meaning; both are types of furniture you can sit on, and this reflects the characteristic semantic paralexia observed in deep dyslexia.
Unlike some types of dyslexia which primarily involve difficulties with phonological processing leading to letter reversals or word jumbles, deep dyslexia is associated with the production of semantic paralexias, where the person reads a word with a related meaning but not the correct word.
Other symptoms may include difficulty reading non-words, phonological dyslexia, and other language deficits that can extend to writing and speech.
