Differences Between Language Disorders
Language Characteristics of Speech Language Impairment (SLI):
- Difficulty learning language rules – extracting regularities from language
- Formation of morphological and phonological rules in language (word endings and sound combinations)
- Decreased vocabulary development
- Difficulty understanding different contexts for language and constructing word associations for vocabulary growth.
Language Characteristics of Children with Language Learning Disability (LLD)
- Understanding and utilizing language rules is particularly difficult – interferes with the development of complexity of sentences and language.
- Problems with morphological markers such as omission of necessary word endings – in both spoken and written modality
- Word-finding and retrieval problems in both conversations and narratives – leads to frequent communicative breakdowns.
- Overall oral language development may be deficient compared to peers.
