Editing Chinese characters (section)

=== Neurolinguistics ===
Using [[functional magnetic resonance imaging]] (fMRI), [[neurolinguist]]s have studied the brain activity associated with literacy. Compared to phonetic systems, reading and writing with characters involves additional areas of the brain—including those associated with visual processing.{{sfn|Demattè|2022|p=9}} While the level of memorization required for character literacy is significant, identification of the phonetic and semantic components in compounds—which constitute the vast majority of characters—also plays a key role in reading comprehension. The ease of recognition for a given character is impacted by how regular the positioning of its components is, as well as how reliable its phonetic component is in indicating a specific pronunciation.{{sfn|Lee|2015b}} Moreover, due to the high level of homophony in Chinese languages and the more irregular correspondences between writing and the sounds of speech, it has been suggested that knowledge of orthography plays a greater role in speech recognition for literate Chinese speakers.{{sfn|Lee|2015a|loc=The Brain Network for Chinese Language Processing}}

[[Developmental dyslexia]] in readers of character-based languages appears to involve independent visuospatial and phonological disorders co-occurring. This seems to be a distinct phenomenon from dyslexia as experienced with phonetic orthographies, which can result from only one of the aforementioned disorders.{{sfnm|1a1=McBride|1a2=Tong|1a3=Mo|1y=2015|1pp=688–690|2a1=Ho|2y=2015|3a1=Taylor|3a2=Taylor|3y=2014|3pp=150–151, 346–349, 393—394}}
