The Test of Semantic Reasoning (TOSR) is a new, standardized vocabulary assessment for children and adolescents ages 7 through 17. Semantic reasoning is the process by which new words are learned and retrieved from ones lexicon through analysis of multiple images that convey various contexts of the words meaning.
The TOSR assesses breadth (the number of lexical entries one has) and depth (the extent of semantic representation for each known word) of vocabulary knowledge without taxing expressive language skills, providing an important new resource for individuals assessing children with possible language and literacy deficits. Breadth and depth are both important for literacy. Breadth is related to early decoding, and depth to later comprehension.
