Small-set segmental identification experiments were conducted with three deaf-blind subjects who were highly experienced users of the Tadoma method. Systematic variations in the positioning of the hand on the speaker's face for Tadoma produced systematic effects on percent-correct scores, information transfer, and perception of individual…

The study examined the ability of five deaf-blind subjects to receive fingerspelled materials through the tactual sense, and of six deaf subjects to receive fingerspelling through the visual sense. Results found highly accurate tactual reception at normal rates and suggested that rates for visual reception are limited by the rate of manual…

This article uses a case study of a deaf-blind infant to examine issues in the early cognitive development of such infants. The study used an ecological approach involving naturalistic observation, videotaping, anecdotal accounts, and the use of four global developmental scales. (DB)

This qualitative study identified 4 major themes during interviews with 28 families whose children have dual sensory impairments. Concerns clustered around parental perceptions of a "good life" for their children, and their experiences with fear, frustration, and change. (Author/DB)

This study evaluated the relationship between the play behaviors of 18 deaf blind children (aged 3-12) and their communication skills using the Play Assessment Scale and several multidomain developmental checklists. Results revealed that behaviors observed during play assessment were highly related to ratings of receptive, expressive, and…

Experienced deaf-blind users (N=10) of sign language tested their ability to receive signed messages including isolated signs and sentences. A set of 122 isolated signs was received with an average accuracy of 87%. Signed sentence reception accuracy ranged from 60-85%, with errors accounted for primarily by deletions and phonological or…

The Communication Observation Schedule (COS) records systematically the pragmatics of communication with children who have deaf-blindness and are functioning from the prelanguage to true words level. The COS provides the opportunity to record the purpose of an interaction, who initiates and who responds to it, the mode of response, and whether the…

This article reports the results of policy research survey examining U.S. government strategies to obtain data on counts of children who are deaf-blind and the issues related to this effort and its outcomes. Problems frequently cited were varying definitions of deaf-blindness among states and lack of accurate data on etiology and severity. (JDD)

Two studies (with 78 experts in deaf blindness and multiple disabilities and 44 parents of children with deaf blindness) explored the content and social validity of an educational planning tool--COACH (Choosing Options and Accommodations for Children). Combined results provide initial validation that COACH is congruent with exemplary practice.…

Most children who are congenitally deafblind are severely delayed in their communication development and many will not achieve symbolic understanding and expression. This article discusses developmental markers cited in the research literature as predictive of or facilitative of the development of symbolism. These markers include the growth toward…

This paper describes the planning of a qualitative research methodology to develop strategies to improve and expand social interaction skills of deaf-blind students in supported employment settings. Characteristics of qualitative research are delineated and include: definition of the domain of the research; an evolving study design; behavior…
