Application

Assesses verbal fluency. This is the ability to find words with particular characteristics in one’s mental lexicon and verbalize them. There are two subdimensions of verbal fluency: semantic and lexical (also called phonemic) word fluency. A certain degree of verbal fluency is essential in order to be able to function in social and work-related situations. Assessment of verbal fluency is particularly important in clinical neuropsychology, because verbal fluency is impaired in many different neurological and psychiatric disorders.

Administration
