language sample analysis
Also written as: LSA — Language Sample Analysis
Systematic examination of spontaneous speech to assess various aspects of language development and use.
Full Definition
Language sample analysis (LSA) involves collecting and analyzing samples of natural, connected speech to evaluate linguistic competence across multiple domains including morphology, syntax, semantics, and pragmatics. This assessment method provides ecologically valid information about how individuals use language in functional contexts, complementing standardized testing. Analysis may examine mean length of utterance, grammatical complexity, vocabulary diversity, narrative structure, and pragmatic appropriateness. LSA is particularly valuable for assessing individuals from diverse linguistic backgrounds and those who may not perform well on standardized measures.
Usage
