What Is A Rhyme To A Deaf Person?
My answer to the question is probably nothing. Watch us get our neuroscience on.
In an aim to see if sign languages, like oral languages, organize elementary, meaningless units into meaningful semantic units, there was a comparison, at behavioral and neurophysiological levels, the processing of the location parameter in French Belgian sign language to that of the rhyme in oral French. Ten hearing and ten profoundly deaf adults performed a rhyme judgment task in oral language and a similarity judgment on location in sign language. The stimuli were pairs of pictures.
Deaf subjects’ performances, although above chance level, were significantly lower than that of hearing subjects regarding oral languages, suggesting that a metaphonological (ability to manipulate speech sounds auditorily) analysis is possible for deaf people but rests on phonological (speech sounds) representations that are less precise than in hearing people. Deaf subjects scores indicated that a metaphonological judgment may be performed on location regarding sign language.
The contingent negative variation (In a chronometric paradigm, the first stimulus is called the warning stimulus and the second stimulus, often one that directs the subject to make a behavioral response, is called the imperative stimulus. The foreperiod is the time between the warning and imperative stimuli. The time between the imperative stimulus and the behavioral response is called the reaction time. The CNV, then, is seen in the foreperiod, between the warning and imperative stimulus.) evoked by the first picture of a pair was similar in hearing subjects in oral language and in deaf subjects in oral language and sign language.
However, an N400 (brain response to words and other meaningful or potentially meaningful stimuli, including visual and auditory words, sign language signs, pictures, faces, environmental sounds, and smells) evoked by the second picture of the non-rhyming pairs was evidenced only in hearing subjects in oral languages. The absence of N400 in deaf subjects may be interpreted as the failure to associate two words according to their rhyme in oral language or to their location in sign language.
Although deaf participants can perform metaphonological judgments in oral language, they differ from hearing participants both behaviorally and in event related potential (measured brain response that is the direct result of a specific sensory, cognitive, or motor event). Judgment of location in sign language is possible for deaf signers, but, contrary to rhyme judgment in hearing participants, does not elicit any N400.
The dude in the video was definitely going hard at somebody, but he probably wasn’t rhyming.
