"The acquisition of grammar is... intimately intertwined with lexical acquisition, supporting a model of language growth in which the different levels of language develop synergistically, bootstrapping learning interactively." - de la Cruz-Pavía et. al, 2021
As children develop language, emerging mastery of underlying grammatical structures becomes apparent through intentional use of morphemes, modifiers, contractions, and word order to demarcate relationships between semantic concepts. For some children, these syntactic markers may develop at a slower rate, impacting the child's expressive language competence. In these cases, simple grammatical concepts, such as subjects of a sentence preceding verbs and verbs preceding objects, may require support in order to be internalized and habituated to functional communication contexts.
The impacts of poor syntax can become more apparent as language experiences begin to involve more complex grammatical constructions (compound and complex sentences, embedded clauses, etc.) within books and conversations. Children with poor understanding of syntax are likely to experience cascading impacts across other language domains, as they have a reduced ability to understand and infer information. This may lead to considerable receptive language deficits.
Additionally, poor syntax usually manifests in expressive communication skills, with children demonstrating poor narrative/tell abilities, incorrect word order, omission of words in sentences, fewer complex sentences, and low MLU. This underlying constraint may significantly limit the extent to which children are able to accurately and effectively share their ideas.
INTERVENTION APPROACHES
Play-Based Modeling Intervention: Particularly for young children, providing language models of desired syntactic structures can be an effective and functionally relevant approach to intervention. In a play context, this is often performed through expansions, recasts, and extensions, (whereby clinicians model restructured versions of children's utterances), by providing numerous models of the target structure(s), and by structuring activities so that specific language structures may be naturalistically compelled. For example, a clinician trying to build a child's use of relative clauses might introduce a play experience featuring similar human figurines that require the child to use distinguishing characteristics to specify particular figurines ("the girl who has the ponytail" "The lady with the classes"). These strategies may be easily modeled to parents for home facilitation, supporting continued carryover.
Structured Intervention Experiences: Clinician-directed experiences focus the intervention time on specific sentence structures. Through repeated trials or use of visual prompts, these experiences can help children to better conceptualize the target structure and utilize it more intentionally. Such experiences might include narrative retells, sequencing activities, or practice using key phrases or conjunctions (and, but, and then, because).
Alternative/Societal/Access-Based Approach: Children who have difficulties with word order may struggle to understand multi-step directions delivered within elaborate sentences. While modeling diverse linguisitic structures helps children to build their syntactic skills, these children are better able to cooperate with instructions that are delivered in shorter steps. Furthermore, the word order of instructions given should match the intended chronology of the steps (e.g. "put that in the trash and go wash your hands" rather than "wash your hands after you put that in the trash"). Checking for understanding can also support children with syntactic difficulties to benefit from language experiences.
ASSESSMENTS
Comprehensive Assessment of Spoken Language, Second Edition, is a comprehensive language assessment for measuring language processing skills for ages 3 to 21 years across four structural categories: Lexical/Semantic, Syntactic, Supralinguistic and Pragmatic Language.
CELF-5 provides clinicians with a streamlined, flexible battery to assess semantics, morphology, syntax, and pragmatics for students ages 5-21. CELF-5 features structured and authentic tests of language ability (including observational and interactive measures) for a complete picture of students' language skills.
