What is the NAVS?


The Northwestern Assessment of Verbs and Sentences (NAVS) was designed to examine comprehension and production of action verbs, production of verb argument structure in sentence contexts, and comprehension and production of canonical and non-canonical sentences in individuals with language disorders resulting from neurological disease. Therefore, it provides a comprehensive assessment of production and comprehension of verbs and sentences.

The NAVS consists of five subtests: the Verb Naming Test (VNT), the Verb Comprehension Test (VCT), the Argument Structure Production Test (ASPT), the Sentence Production Priming Test (SPPT), and the Sentence Comprehension Test (SCT).  The VNT and VCT examine production and comprehension of isolated verbs that differ with respect to their argument structure. The ASPT evaluates production of these verbs together with their arguments in a sentence production task. Verb argument structure and optionality effects are examined using verb types (i.e., one-, two-, and three-argument verbs) as singletons (i.e., in the VNT and VCT) and in a sentence context (i.e., in the ASPT). Production and comprehension of sentences by canonicity and sentence type are examined in the SPPT and the SCT , respectively, using six sentence types (i.e., three canonical forms: active, subject extracted wh-question (SWQ), and subject relative clause (SR); three noncanonical forms: passive, object extracted wh-question (OWQ), and object relative clause (OR)).
