Though the word may be the same , for your mental capacity , reading a sentence aloud is nothing like write it down . Some people who have brain price from strokes or combat injury might be able-bodied to write the watchword “ Take the dog to the common , ” but not say the sentence out loud , and frailty versa .
This is because , as connected as writing and speaking seem ( at least with ABC’s like English , as oppose to Chineselogograms ) , the brain treats the two process as fairly independent , a raw cogitation in the journalPsychological Scienceconcludes .
researcher in cognitive scientific discipline and psychology from Johns Hopkins University , Rice University , and Columbia University studied five hoi polloi with stroke - relatedaphasia , or difficulty communicate because of brain damage . Four exhibit difficulty publish but not address , and one had trouble speak but not writing . The participant looked at images and were necessitate to drop a line and speak unproblematic descriptions of what was happening .

The participants all exhibited issues with prosody — correctly say , for instance , “ the boy is walk , ” but writing “ the male child is walked ” instead , or say “ two shirt ” instead of “ two shirt . ” The subject field authors conclude that these errors in morphemes ( the smallest grammatical unit of measurement of nomenclature , like “ -ed ” and “ -ing ” ) reflect differences in the way the mentality mental process speak versus write language , so that while brain damage may touch on one process , it does n’t impact the other .
" We found that the mentality is not just a ' dumb ' political machine that knows about letters and their order of magnitude , but that it is ' impudent ' and advanced and bed about watchword parts and how they fit together , " Brenda Rapp , one of the study ’s generator and a cognitive scientist , explained in apress program line .
While five multitude is n’t typically enough for any sort of substantive research finding , this does bolsterprevious researchabout the dissimilar ways the brain processes speaking and authorship , and how that can explainfluency in one areabut not the other in aphasia patient .
