Studies have shown that iconicity can provide a benefit to non-signers during the learning of single signs, but other aspects of signed messages that might also be beneficial have received less attention. In particular, do other features of signed languages help support comprehension of a message during the process of language learning? The…

This dissertation explores the hypothesis that language processing proceeds in "windows" that correspond to representational units, where sensory signals are integrated according to time-scales that correspond to the rate of the input. To investigate universal mechanisms, a comparison of signed and spoken languages is necessary. Underlying the…

Sentence processing in American Sign Language (ASL) was investigated as a function of age of first language acquisition with a timed grammatical judgement task. Participants were 30 adults who were born deaf and first exposed to a fully perceptible language between the ages of birth and 13 years. Stimuli were grammatical and ungrammatical examples…

We report the results of an experiment investigating the ramifications of using space to express coreference in American Sign Language (ASL). Nominals in ASL can be associated with locations in signing space, and pronouns are directed toward those locations to convey coreference. A probe recognition technique was used to investigate the case of…

We introduce a new method of sign language subtitling aimed at young deaf children who have not acquired reading skills yet, and can communicate only via signs. The method is based on: 1) the recently developed concept of "semantroid[TM]" (an animated 3D avatar limited to head and hands); 2) the design, development, and psychophysical evaluation…

This discussion is based on the results of an earlier experiment in which four groups of deaf subjects, ranging in age of first exposure to signing from birth to over eighteen, were given lists of sentences in American Sign Language to shadow and recall immediately after presentation. It was found that in terms of overall accuracy, early learners…

Metalinguistic abilities of 20 hearing-impaired children, aged 4-10, were assessed by asking them to judge synonymy of sentence pairs presented in Signed English, Pidgin Sign English, and American Sign Language. None of the children had developed metalinguistic abilities in any of the sign language systems. (Author/JDD)
