Language and Cognitive Development of Deaf and Hearing Twin Sisters.
Schirmer, Barbara R.
In this case study, the language and cognitive development of a 4-year 5-month old profoundly deaf girl and her normally hearing identical twin sister were investigated by videotaping the twins in their home interacting with each other, the investigator, and family members. Materials used with the children were designed to elicit spontaneous, representative, expressive language and encourage imaginative play. A language sample of 100 utterances from each child was analyzed along dimensions of syntax, semantics and use. Interaction patterns were analyzed using a description of five dialogue patterns observed between twins and a behavioral observation plan for interpreting these dialogues. Imaginative play was analyzed as a measure of cognitive development. The pattern of differences in their language and imaginative play levels provide limited evidence that language and imaginative play are interrelated reflections of one developing cognitive system.
