Examples These errors can be semantic, in which the meaning of the word is related to that of the intended word (car for van, for example). [16] Semantic paraphasias can be further subdivided into six different types. [12] Coordinate semantic paraphasias replace the target word with one that is from the same category, such as tiger for lion.
Transcortical sensory aphasia is characterized as a fluent aphasia. Fluency is determined by direct qualitative observation of the patient’s speech to determine the length of spoken phrases, and is usually characterized by a normal or rapid rate; normal phrase length, rhythm, melody, and articulatory agility; and normal or paragrammatic speech.

The primary evidence for this role of the MTG-TP is that patients with damage to this region (e.g., patients with semantic dementia or herpes simplex virus encephalitis) are reported [90] [91] with an impaired ability to describe visual and auditory objects and a tendency to commit semantic errors when naming objects (i.e., semantic paraphasia ...
The more phonemic paraphasias in a word, the harder it is to understand, to the extent at which may become unidentifiable. Often, these unidentifiable words are known as neologisms. Semantic (verbal) paraphasia: Failure to select the proper words with which to convey their ideas. The word used is always a real word, however it may not always be ...
Patient's naming ability is contaminated by paraphasia. [6] Modality-specific anomia is caused by damage to the sensory cortex, pathways to the dominant angular gyrus, or both. In these patients, word-finding is worst in one sensory modality, for example visual or tactile. [6]
In neurology, semantic dementia (SD), also known as semantic variant primary progressive aphasia (svPPA), is a progressive neurodegenerative disorder characterized by loss of semantic memory in both the verbal and non-verbal domains. However, the most common presenting symptoms are in the verbal domain (with loss of word meaning).
In psychology and cognitive neuroscience, pattern recognition is a cognitive process that matches information from a stimulus with information retrieved from memory. [1]Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory.
Jargon aphasia is a type of fluent aphasia in which an individual's speech is incomprehensible, but appears to make sense to the individual. Persons experiencing this condition will either replace a desired word with another that sounds or looks like the original one, or has some other connection to it, or they will replace it with random sounds.
