Anomic aphasia, also known as dysnomia, nominal aphasia, and amnesic aphasia, is a mild, fluent type of aphasia where individuals have word retrieval failures and cannot express the words they want to say (particularly nouns and verbs). [1]
William James was the first psychologist to describe the tip of the tongue phenomenon, although he did not label it as such. The term "tip of the tongue" is borrowed from colloquial usage, [2] and possibly a calque from the French phrase avoir le mot sur le bout de la langue ("having the word on the tip of the tongue").
Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in the Global North. [3]
Although the connection of the words may be appropriate, the words they are using may not belong together or make sense (Jargon). [11] Some patients with Wernicke's Aphasia experience logorrhea, which is also known as over fluency. These patients use an excessive amount of words when speaking or writing. [12]
Expressive aphasia (also known as Broca's aphasia) is a type of aphasia characterized by partial loss of the ability to produce language (spoken, manual, [1] or written), although comprehension generally remains intact. [2]
During each check-in, participants reported their activity over the past few hours and also played a few virtual "brain games" to measure their cognitive functioning.
Cluttering is sometimes confused with stuttering. Both communication disorders break the normal flow of speech, but they are distinct. A stutterer has a coherent pattern of thoughts, but may have a difficult time vocally expressing those thoughts; in contrast, a clutterer has no problem putting thoughts into words, but those thoughts become disorganized during speaking.
Articulatory suppression is the process of inhibiting memory performance by speaking while being presented with an item to remember. Most research demonstrates articulatory suppression by requiring an individual to repeatedly say an irrelevant speech sound out loud while being presented with a list of words to recall shortly after.
