Also known as literal paraphasia, it is when a sound substitution or rearrangement is made, but the stated word still resembles the intended word. Examples include saying “dat” instead of “hat” or “tephelone” instead of “telephone.” At least half the word must be said correctly to be considered a phonemic paraphasia.
Does Wernicke’s aphasia have Paraphasic errors?
In Wernicke’s aphasia language output is fluent with a normal rate and intonation. However, the content is often difficult to understand because of paraphrastic errors.
Does Broca’s aphasia have Paraphasic errors?
L Broca’s Aphasia. Broca’s aphasia is one of the most commonly known syndromes of frontal language disorder. The core features of this syndrome include nonfluent, effortful speech production, semantic and phonemic paraphasias, articulatory errors, agrammatism, and relatively preserved comprehension.
What is a semantic Paraphasia?
Paraphasia refers to the substitution of an unexpected word for an intended target. Semantic paraphasias often have a clear semantic relationship to the desired word and represent the same part of speech (Goodglass, 1993).
What is a semantic error in aphasia?
Semantic paraphasias were defined as all incorrect real word responses related to the target in meaning. Phonological paraphasias were defined as real word attempts with phonological similarities as well as non-word attempts with incorrect phonemes that preserved more than 50% of the target word.
What’s a Paraphasia?
Paraphasias are defined as unintended utterances. In essence, there is a failure of selection at the phonemic level, producing a phonemic (literal) paraphasia (e.g., “I drove home in my lar”) or at a word (lexical) level (e.g., “I drove home in my wagon”), producing a verbal paraphasia (Table 3-3).

A comparison between targets and formal paraphasias indicated a high agreement. both in word class, number of syllables, stress pattern, and in basic (stressed) vowels. The agreement in consonants (including word-initial consonants), how-
What causes Wernicke’s aphasia?
Wernicke aphasia is characterized by impaired language comprehension. Despite this impaired comprehension, speech may have a normal rate, rhythm, and grammar. The most common cause of Wernicke’s aphasia is an ischemic stroke affecting the posterior temporal lobe of the dominant hemisphere.
What is a Paraphasia?
What causes phonemic paraphasia in the temporal lobe?
These types of errors are associated with Wernicke’s aphasia, among others. Phonemic paraphasias are often caused by lesions to the external capsule, extending to the posterior part of the temporal lobe or internal capsule. This type of paraphasia also occurs in other languages as well.
How are phonemic paraphasias related to anomia?
It is the product of a breakdown at a stage of word-retrieval process and is a dominant symptoms within the more general category of anomia. Phonemic paraphasias also called literal paraphasias, involve the substitution, addition, or rearrangement of speech sounds so that the error can be identified as sounding like the target.
How are verbal paraphasias related to nonfluent aphasias?
Verbal paraphasias are the only type of paraphasias that can also be linked to nonfluent aphasias, and they are mainly caused by lesions to the posterior temporal region of the brain, the head of the caudate nucleus, or both.
Can a low frequency paraphasia occur in normal speech?
While low-frequency paraphasic errors can occur in normal speech, paraphasias (particularly phonological paraphasias) are considerably more common in Wernicke’s aphasia and in Sensory Transcortical Aphasia. Phonemic paraphasia, also literal paraphasia – Mispronunciation, syllables out of sequence.
