What type of aphasia is characterized by a higher frequency of paraphasic errors?

Fluent aphasia is marked by the ability to produce speech that flows well, but the content of the speech often includes a significant number of paraphasic errors. Paraphasias are instances where words are substituted incorrectly, which can manifest as phonemic errors (sound substitutions) or semantic errors (substituting a word with another that is related in meaning).

In fluent aphasia, individuals may string together a series of words that have a normal rhythm and prosody, but the overall message can be confusing due to these errors. This is often observed in conditions like Wernicke’s aphasia, where comprehension is also impaired, leading to less meaningful output despite normal speech patterns.

Other options do not align as closely with the characteristics of fluent aphasia. Expressive aphasia typically results in notable difficulties in word retrieval and forming sentences, leading to more telegraphic speech rather than fluent output. Non-fluent aphasia focuses on reduced speech output with effortful production, while global aphasia presents with severe impairments across all language modalities, resulting in very limited speech and significant difficulty in both expressing and understanding language.
