This paper presents findings from a study on the use of sign supported Norwegian (SSN) in two individuals with Cri du chat syndrome (CCS). The study gives a first account of some selected aspects of production and intelligibility of SSN in CCS. Possible deviance in manual parameters, in particular inter- and/or intra-subject variation in the use…

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…

Novel word learning in three conditions (signed only, spoken only, signed and spoken combined) was compared for young children (N=10) with Down syndrome and mental-age matched controls. No group differences in frequency of imitations or productions were obtained. The frequency of imitations was highest in the combined condition. In the combined…

The effectiveness of verbal, sign, and simultaneous systems for the acquisition of receptive language by an autistic boy was investigated. Results suggest nonsignificant differences among the three methods. (Author/SEW)

This study of four moderately to severely aphasic subjects found that success in manual sign training programs is related to severity of aphasia, that aphasic subjects' propositional use of manual signs rarely follows simple acquisition, and that generalization to untrained stimuli or environments does not occur without additional training.…

Acquisition of the location aspect of American Sign Language signs was examined in nine young hearing infants and toddlers of deaf parents. Sign locations, overall, were produced with 83.5% accuracy. Highly contrasting locations were acquired first. Location played a central role in young children's early sign language acquisition. (Author/DB)
