Final answer:
Deep dyslexia is the form of acquired dyslexia where a patient reads a word as another semantically-related word. It involves difficulties in processing phonemes and often leads to the substitution of words with similar meanings.
Step-by-step explanation:
Deep dyslexia is a form of acquired dyslexia in which the patient incorrectly reads a word as another semantically-related word. Despite being called 'deep', this form does not imply a more severe level of dyslexia, but rather refers to the fact that the error made is related to the meaning of the word the patient intended to read. Patients with deep dyslexia have difficulty processing phonemes, the smallest units of sound that can change the meaning of a word, and thus often substitute the intended word with another that has a related meaning.
Dyslexia is a common learning disability characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language and are unexpected in relation to other cognitive abilities. In the context of the given question, 'deep dyslexia' is the answer.
