The use of an idiosyncratic gesture system, called homesign within the Deaf community, almost certainly puts an adolescent first-language learner at an advantage relative to someone like Genie, who was punished for trying to communicate.
Maria used no speech and communicated with her family in homesign.
According to parental report, Marcus could say three words: "What," "Papa," and "Mama," and depended primarily upon homesign to communicate with his family.
Type of predicate was determined by whether the action was encoded in a homesign gesture, an uninflected sign, an inflected verb, or a classifier predicate.
In her earliest descriptions of events of climbing and falling, she depended almost exclusively on homesign gestures, in which she used her body or her hand to depict movement, as in (2), which she produced by tracing a path on the picture of the frog climbing out of the jar to escape his captors (see Figure 6).
Compare this with Maria's homesign strategy of tracing the path of the frog's movement on the picture book (cf.
Marcus again shows a more prolonged use of homesign than Maria but also begins using verb agreement earlier than Maria.
When children and adolescents first came together at the school (the Melania Morales School for Special Education) in the late 1970s, they brought with them their homesign systems," said the researchers.
Other studies on this 'homesigning' have usually stopped at the point the children go to school, but I have been able to follow children in Nicaragua who are not near a special education school and accordingly continue developing their homesigns independently," said Marie Coppola, a Research Associate at the University of Chicago.
Washington, Feb 08 (ANI): A new study has concluded that people who communicate using self-developed gestures, called homesigns, were unable to comprehend the value of numbers greater than three because they had not learned a language containing symbols used for counting.
They then asked the deaf individuals to retell the video to a friend or relative using homesigns.
