The child who does not talk.
The majority of normal children will have developed some speech by the age of two years. Significant delay in speech development may be the result of (1) deafness, (2) mental retardation, (3) faulty innervation of the speech organs, (4) aphasia, (5) autism, (6) a family trait, (7) hospitalism, (8) parental neurosis, or (9) some combination of these factors. Each nonspeaking child needs an individually planned study for precise diagnosis and recommendation for treatment.
