Acquisition and cross modal generalization of receptive and expressive signing skills in a retarded deaf girl.
A transfer of stimulus control procedure was used to teach a retarded deaf girl manual signing skills. Eight manual signs were trained in the receptive modality; eight others in the expressive modality. Acquisition of receptive and expressive signing skills occurred for most signs after they had been trained in multiple baseline order. There was a marked difference in cross modal generalisation between each of the trained signing modalities. With some exception training of receptive sign discrimination had little effect on the expressive usage of these signs. In contrast, training in the expressive usage resulted in a near perfect acquisition of receptive sign discrimination.
