Children with autism spectrum disorder (ASD) who have native exposure to a sign language such as American Sign Language (ASL) have received almost no scientific attention. This paper reports the first studies on a sample of five native-signing children (four deaf children of deaf parents and one hearing child of deaf parents; ages 4;6 to 7;5)…

Learning to read is a major obstacle for children who are deaf. The otherwise significant role of phonology is often limited as a result of hearing loss. However, semantic knowledge may facilitate reading comprehension. One important aspect of semantic knowledge concerns semantic categorization. In the present study, the quality of the semantic…

The learning of a list of 20 Blissymbols and comparable American Sign Language signs by 121 nonhandicapped undergraduate psychology students was compared. Blissymbols were learned significantly faster than manual signs, particularly in early learning trials. Results are discussed in terms of the memory requirements of the two systems. (Author/JDD)

Differential acquisition of American Sign Language and Amerind signs was compared among moderately to severely mentally handicapped adolescents (n=10) in a residential training facility. Results showing both quicker acquisition and stronger retention of Amerind signs were thought to result from the more concrete and less complex nature of Amerind…
