Learning Disorder Symptoms - Expressive Language Disorder
Expressive Language Disorder
The scores obtained from standardized individually administered measures of expressive language development are substantially below those obtained from standardized measures of both nonverbal intellectual capacity and receptive language development. The disturbance may be manifest clinically by symptoms that include having a markedly limited vocabulary, making errors in tense, or having difficulty recalling words or producing sentences with developmentally appropriate length or complexity.
The difficulties with expressive language interfere with academic or occupational achievement or with social communication.
Criteria are not met for Mixed Receptive-Expressive Language Disorder or a Pervasive Developmental Disorder.
If Mental Retardation, a speech-motor or sensory deficit, or environmental deprivation is present, the language difficulties are in excess of those usually associated with these problems.
