Someone with<unk>  may exhibit the following behaviors: * intermixing real words and nonsensical words while speaking or writing * failing to recognize mistakes being made while speaking or writing * using real words in incorrect situations * frequent, repetitive uttering of low-frequency words * the inability to say or write a specific word or phrase Some of the specific types of language errors that occur are: ; lexical (real word) :; semantic :: Real word that was semantically related to target. ("dog" instead of "cat") :; formal :: Real word that shared either the initial phoneme or at least 50% of phonemes with target. ("dog" instead of "desk" or "dog" instead of "frog") :; mixed :: Real word that was both semantically and phonologically related to target. ("bicycle" instead of "motorcycle") :; visual :: Real word of an item similar in visual form to the target. ("ball" instead of "orange") :; unrelated :: Real word that was not related to the target in any obvious way. ("dog" instead of "apple") ; non-lexical (nonword) :; phonological :: Nonword that shared either the initial phoneme or at least 50% of phonemes with target. ("deg" instead of "dog") :; neologistic :: Nonword not reaching the criterion for phonological relatedness (i.e., sharing less than 50% of phonemes with the target and with a different initial phoneme). Nonwords that are pseudo-compound words. ("kib" instead of "dog") ; other errors :; Don't know :: Indication that response was unknown or item was not responded to at all. ("I don’t know" or silence) :; description :: Attempts to describe as opposed to name item. (Multiple word responses)<unk>  must be diagnosed through a series of tests. Since the number of individuals that have aphasia after suffering a stroke is high, a test is usually carried out soon after the stroke occurs. There is a list of basic exercises to help assess a person's language skills, such as: * naming objects that begin with a certain letter * reading or writing * holding a conversation * understanding directions and commands There is also a common test used, called the Boston Diagnostic Aphasia Examination test, which incorporates exercises that extensively review the person's language skills.
