Northwestern Naming Battery (NNB)


Project TitleNorthwestern Naming Battery (NNB)
Track Code2012-108
Short Description

The Northwestern Naming Battery (NNB) examines noun and verb comprehension and naming, as well as auditory discrimination, lexical decisions, semantic associates, non-word and word repetition in individuals with language disorders resulting from neurological disease. Results provide a cognitive neuropsychological profile of lexical semantic processing.

What is NNB?

The NNB was designed to examine comprehension and production of several categories of objects and actions, while ruling out other deficits that could be related to naming or word comprehension impairments. Therefore, it provides a comprehensive assessment of production and comprehension of nouns and verbs as well as assessments of peripheral auditory processing and object recognition ability. Subtests also are included to evaluate the integrity of semantic and word form access/selection systems.

The NNB consists of seven subtests: (1) Auditory Discrimination, (2) Auditory Lexical Decision, (3) Confrontation Naming, (4) Auditory Comprehension, (5) Semantic Associates, (6) Non-word Repetition, and (7) Word Repetition. The first two subtests, Auditory Discrimination and Auditory Lexical Decision, examine auditory processing ability for words and non-words. In the Confrontation Naming and Auditory Comprehension subtests, noun category effects are testing using items from two non-living things (artifacts) (i.e., tools and clothing) and two categoriesof living things (i.e., animals and fruits/vegetables). A fifth set of object nouns includes only low frequency items from several semantic categories. In addition, naming of body parts and colors are tested in both the Confrontation Naming and Auditory Comprehension subtests. The action verbs tested consist of both transitive and intransitive forms. The Semantic Associates subtest examines semantic processing by asking participants to select pairs of pictured objects according to how related they are in meaning. Finally, the Word and Non-word Repetition subtests examine the ability to repeat both real and non-words.



The Northwestern Naming Battery (NNB) is available via a license from Northwestern University for research and clinical use.
