Cognitive intervention through virtual environments among deaf and hard-of-hearing children

The lack of the auditory sense in the hearing-impaired raises the question as to the extent to which this deficiency affects their cognitive and intellectual skills. Studies have pointed out, that with regard to reasoning, particularly when the process of induction is required, hearing-impaired children usually have difficulties. They experience similar difficulties with their ability to think in a flexible way. Generally, a large body of literature suggests that hearing-impaired children tend to be more concrete and rigid in their thought processes. This study aimed at using Virtual Reality as a tool for improving structural inductive processes and the flexible thinking with hearing-impaired children. Three groups were involved in this study: an experimental group, which included 21 deaf and hard-of-hearing children, who played a VR 3D game; a control group, which included 23 deaf and hard-of-hearing children, who played a similar 2D (not VR game); and a second control group of 16 hearing children for whom no intervention was introduced. The results clearly indicate that practising with VR 3D spatial rotations significantly improved inductive thinking and flexible thinking of the hearing-impaired.     

Transition for Deaf and Hard-of-Hearing Students: A Blueprint for Change

The large and growing number of deaf and hard-of-hearing adults who are "low-functioning deaf" (LFD), the unmet needs of many young people who are deaf or hard of hearing, and the continuing high rates of dropping out argue for a change in secondary programming for multiply disabled deaf and hard-of-hearing students and for others who are at risk of becoming LFD as adults. The LFD designation refers to youth and adults who read at very low levels, whether or not they have a second disability in addition to hearing impairment. This article reviews research related to transition for adolescents with disabilities as well as those who are deaf or hard of hearing. It then offers a case for change, one that, for the United States, represents a poignant return to a time past.     

Deaf/hearing cultural identity paradigms: modification of the deaf identity development scale

The Deaf Identity Development Scale (Glickman, 1993) was modified to include hearing individuals and examine how hearing and deaf adults identify themselves. Statistical analysis based on 244 deaf, hard-of-hearing, and hearing respondents revealed a significant interaction between hearing status of self and parents on the hearing, marginal, and immersion scales of the modified version but not on the bicultural scale. Codas are more marginalized, less immersed, and similarly 'hearing' in comparison to deaf persons with deaf parents. Hard-of-hearing respondents with deaf parents endorse more hearing values and fewer deaf values in comparison to deaf counterparts and also appear to be more marginalized. There were no significant differences between deaf and hard-of-hearing individuals with hearing parents. Compared to hearing respondents with hearing parents, deaf counterparts were more marginalized, more 'hearing,' and equally 'deaf.' Strong professional affiliation with the deaf community resulted in scores that differed significantly from those for individuals not as strongly affiliated. We discuss implications for identity development.     

Deaf and hard-of-hearing adolescents’ experiences of inclusion and exclusion in mainstream and special schools in Sweden

This study examines the question of which school environment – special or mainstream school – is more favourable for deaf and hard-of-hearing students in Sweden, when it comes to their well-being, and their social and academic inclusion. The aim is threefold: first to compare the well-being of adolescents who are deaf or hard-of-hearing, who are deaf or hard-of-hearing and have additional disabilities, and who have no disabilities; second to compare the adolescents from the two deaf and hard-of-hearing groups and their experiences of inclusion and exclusion in school; and third to ascertain if any gender differences exist between the two groups of deaf and hard-of-hearing students concerning their experiences of inclusion and exclusion. A total of 7865 adolescents (13–18 years of age) answered a total survey about the life and health of young people in a county in Sweden. The results show that both boys and girls in the hard-of-hearing groups rated their well-being lower and were less satisfied with their lives than pupils without disabilities. They also show that the hard-of-hearing boys and girls attending special school were more satisfied with their lives and to a greater extent felt included both socially and academically than students in mainstream school.     

Career and workplace experiences of Australian university graduates who are deaf or hard of hearing

This article reports on the experiences of a group of deaf and hard-of-hearing alumni of Griffith University in south-east Queensland, Australia. Participants completed a survey answering questions about their communication patterns and preferences, working lives, career barriers or difficulties anticipated and encountered, and workplace accommodations used or sought. Results revealed a range of career barriers and workplace difficulties encountered by these participants, as well as solutions found and strategies used by them. Differences in employment sector, job-search activities, difficult workplace situations, and use of accommodations were noted between 2 groups: those who communicated primarily in Australian Sign Language and considered themselves to have a Deaf or bicultural identity and those who communicated primarily in spoken English and considered themselves to have a hearing identity. Implications for university services supporting deaf and hard-of-hearing students are outlined, and suggestions for further research are made.     

When parents are deaf versus hard of hearing: patterns of sign use and school placement of deaf and hard-of-hearing children

This paper investigates the importance of knowing whether or not deaf and hard-of-hearing students have one or more deaf or hard-of-hearing parents. As noted by Mitchell and Karchmer (2004), deaf and hard-of-hearing school-age children and youth in the United States with at least one parent identified as "hearing impaired" are nearly evenly split between having at least one deaf parent and having at least one hard-of-hearing parent. However, there is no literature on the importance, if any, of this distinction. Findings from the investigation reported herein suggest that the distinction between having a deaf versus a hard-of-hearing parent is quite substantial, particularly as it pertains to the use of signing in the home. Further, signing in the home, which is reliably predicted by parental hearing status, is a significant predictor of the school setting in which the student is currently placed and the instructional use of signing in the classroom. Limitations related to the available measure of parental hearing status are discussed.     

Inclusive education and personal development

Open-ended questionnaires covering mainstream educational experiences and personal development of deaf and hard-of-hearing adults were analyzed. Half of the 34 deaf and hard-of-hearing respondents altered self-labels based on changes in personal definitions rather than audiological changes. Supportive school environments and coping skills contributed to positive perceptions; nonsupportive school environments and being treated as 'different' were viewed negatively. Everyone valued contact with hearing peers. Contact with deaf peers depended on finding those with similar values. Identification with Deaf culture was nonexistent. Most noteworthy, 24 of 34 participants felt caught between the deaf and hearing worlds, indicating the need for niches in both. Implications for educators are that development of self-confidence and comfort with identity may be enhanced by validating the deafness dimension through opportunities for contact with deaf adults and positive relationships with both deaf and hearing peers.     

A national profile of school-based transition programs for deaf adolescents.

In this study, the transition programs of 326 secondary educational programs for deaf and severely hearing-impaired adolescents were surveyed. Three types of programs were surveyed: residential, mainstream, and "other" (a combination of the first two programs). Sixty-four items depicting desirable transition characteristics were included in the survey, and each item was rated by the programs on a value scale and an implementation scale. Analyses of variance were calculated to determine if there were statistically significant differences among the three program types for each individual survey item on the two rating scales. Based on the data, it appears that the residential schools had higher implementation rates than the mainstream and other programs. All three respondent groups valued the transition items more than they had implemented them (i.e., the value scores were higher than the implementation scores). The data point out the need for researchers and educators to develop and implement more effective transition programs for deaf and severely hearing-impaired students.     

The relative difficulty of signed arithmetic story problems for primary level deaf and hard-of-hearing students

This study determines the relative difficulty and associated strategy use of arithmetic (addition and subtraction) story problems when presented in American Sign Language to primary level (K-3) deaf and hard-of-hearing students. Results showed that deaf and hard-of-hearing students may consider and respond to arithmetic story problems differently than their hearing peers, with the critical dimension in problem difficulty being based on the operation typically used to solve the problem, not the story within the problem. The types of strategies used by the students supported the order of problem difficulty. The visual-spatial nature of the problem presentation appeared not to assist the deaf and hard-of-hearing students in solving the problems. Factors that may have contributed to this pattern of problem difficulty are discussed so that educators can better align mathematics instruction to the thinking of the deaf child.     

The Use of Visual-Tactile Communication Strategies by Deaf and Hearing Fathers and Mothers of Deaf Infants

This article presents the results of a study comparing deaf and hearing parents in the use of visual-tactile communication strategies during interaction with their hearing-impaired children between 18 and 24 months of age. The study includes 17 deaf and hard-of-hearing children and 33 parents, covering hearing mothers (n = 12), hearing fathers (n = 11), deaf mothers (n = 5), and deaf fathers (n = 5). The four groups of parents are compared in the use of visual-tactile communication strategies during free play with their children. Overall results show that deaf mothers and deaf fathers differ significantly from hearing parents in the use of a visual communication style adapted to the developmental communication needs and abilities related to the 18- to 24-month age period. The study pays special attention to differences in visual-tactile communication strategies according to hearing status, gender, use of languages, and communication modes.     

Hand/wrist disorders among sign language communicators

The study assessed the frequency of self-reported hand/wrist problems among sign language communicators, including interpreters, deaf or hard-of-hearing individuals, and educators. Comparisons were also made between sign language communicators and the general population regarding the frequency of medically diagnosed carpal tunnel syndrome. A survey was mailed to attendees of a national conference that focused on the quality of postsecondary educational opportunities for students with hearing deficits. Fifty-nine percent of 184 respondents reported experiencing hand/wrist problems. Twenty-six percent reported experiencing hand/wrist problems severe enough to limit the ability to work, and 18% reported a medical diagnosis of wrist tendinitis, carpal tunnel syndrome, or both. The frequency of self-reported, medically diagnosed carpal tunnel syndrome for the surveyed sign language communicators was five times the rate experienced by working Americans between ages 18 and 60 years (Tanaka, Wild, Seigman, Halperin, Behrens, & Putz-Anderson, 1995). The study supports increased emphasis on and availability of hand/wrist disorder risk reduction programs for sign language users.     

The Characteristics and Extent of Participation of Deaf and Hard-of-Hearing Students in Regular Classes in Australian Schools

A national randomly selected survey of a sample of deaf and hard-of-hearing students included in regular classes from kindergarten to high school in Australian preschools and schools was conducted via a questionnaire to itinerant teachers working with such students. This article reports the analysis of a questionnaire that surveyed the demographic characteristics of such students and a set of characteristics of their behavior in their placement in terms of "participation" in aspects of regular class activities. These aspects were level of integration, academic participation, level of independence, and social participation. Data are reported and analyzed in terms of the above demographic and participatory characteristics of the students. We consider comparisons with comparable reports from the United States and Great Britain and discuss implications for deaf and hard-of-hearing students included in regular classes.     

Enhancing the Induction Skill of Deaf and Hard-of-Hearing Children with Virtual Reality Technology

Many researchers have found that for reasoning and reaching a reasoned conclusion, particularly when the process of induction is required, deaf and hard-of-hearing children have unusual difficulty. The purpose of this study was to investigate whether the practice of rotating virtual reality (VR) three-dimensional (3D) objects will have a positive effect on the ability of deaf and hard-of-hearing children to use inductive processes when dealing with shapes. Three groups were involved in the study: (1) experimental group, which included 21 deaf and hard-of-hearing children, who played a VR 3D game; (2) control group I, which included 23 deaf and hard-of-hearing children, who played a similar two-dimensional (2D) game (not VR game); and (3) control group II of 16 hearing children for whom no intervention was introduced. The results clearly indicate that practicing with VR 3D spatial rotations significantly improved inductive thinking used by the experimental group for shapes as compared with the first control group, who did not significantly improve their performance. Also, prior to the VR 3D experience, the deaf and hard-of-hearing children attained lower scores in inductive abilities than the children with normal hearing, (control group II). The results for the experimental group, after the VR 3D experience, improved to the extent that there was no noticeable difference between them and the children with normal hearing.     

An investigation of two-way text messaging use with deaf students at the secondary level

Deaf and hard-of-hearing students are often delayed in developing their independent living skills because of parental restrictions on activities outside the home due to worries about their child's inability to communicate, their whereabouts, and their general safety. Recent accounts of the use of two-way text messagers suggests that, like electronic mail, distance communication problems that have long plagued deaf people may be ameliorated--by the use of such technology (M. R. Power & D. Power, 2004; S. S. Rhone & Cox News Service, 2002). This project was designed as an initial foray into investigating the use of two-way text messaging technology as a way of increasing the independence of deaf adolescents and reducing their parents' anxiety about their safety and responsibility. All the deaf and hard-of-hearing students in the deaf and hard-of-hearing programs at two urban high schools (ages 13-19), the staff of the deaf departments at these two schools, and the parents/guardians of the students participated in this study. Preuse surveys, postuse surveys, and monthly statistics on the number of times each pager was used enabled us to chart how often the participants used the technology. The data were used to identify concerns that parents have about student independence and safety, the extent to which deaf students engage in independent activities, and expectations surrounding how two-way text messaging use might increase independence and literacy skills. The data collected on this project to date confirm that two-way text messaging technology is indeed useful for deaf adolescents and helps alleviate some of the concerns that have kept them from developing independence as quickly or readily as their hearing peers. The potential policy implications for this research are discussed.     

Participation of deaf and hard-of-hearing students in classes with hearing students

This project identified key issues concerning participation of deaf and hard-of-hearing (D/HH) students in regular (mainstream) classes. In one study, qualitative data were collected from 40 participants in focus groups consisting of interpreters, teachers of the deaf, and notetakers. In a second study, repeated field observations were made of four elementary-level D/HH students who were participating in small-group learning activities with hearing classmates. Focus group comments indicated that regular classroom teachers, interpreters, teachers of the deaf, hearing classmates, and D/HH students contribute to active participation by the D/HH student. Focus groups identified specific barriers that interfered with participation of each of these groups of individuals, and they also identified specific strategies to facilitate participation. Qualitative analyses of field observation data yielded results consistent with the comments collected from the focus groups participants. The observations identified accommodations that regular classroom teachers, teachers of the deaf, and interpreters can make to promote integration of the D/HH student. A summary synthesis of the data presents 16 specific strategies for overcoming barriers to participation.     

Hearing, deaf, and hard-of-hearing Israeli adolescents' evaluations of deaf men and deaf women's occupational competence

This study examined 74 deaf and hard-of-hearing (D/HH) and 91 hearing high school students regarding their own occupational aspirations and their evaluations of occupational competence (EOCs) for deaf adults. In the EOC, participants rated the suitability of 25 occupations (varying according to prestige and required level of communication) for deaf men and women. The results showed that occupations requiring intensive communication levels, regardless of their prestige, were evaluated as much less suitable for deaf individuals than were those requiring less communication. D/HH adolescents did not find highly prestigious occupations as suitable for deaf adults even when communication barriers were irrelevant. Both D/HH and hearing participants expressed biased evaluations of deaf women's competence, but no further evidence emerged for stereotypic attitudes. Higher educational aspirations among hearing adolescents, especially hearing males, correlated with a higher EOC of deaf adults. No such associations emerged for D/HH participants. No gender effects emerged. Implications of these outcomes for career development, especially for females, were discussed.     

The impact of a dialogic reading program on deaf and hard-of-hearing kindergarten and early primary school-aged students in Hong Kong

The present study investigated the effects of a special interactive dialogic reading method developed by Whitehurst et al. (1988) on deaf and hard-of-hearing children in Hong Kong. Twenty-eight deaf and hard-of-hearing children in kindergarten, first, or second grade were pretested on a receptive vocabulary test and assigned to one of three conditions, dialogic reading, typical reading, and control, with age and degree of hearing loss matched. After an 8-week intervention, the children were re-tested. The dialogic reading group had a significantly greater improvement in vocabulary scores than did the other two groups. Parent-child interactions of high quality and the use of pictorial materials are likely the key successful factors in the program. The educational value of this intervention is discussed.     

Unique issues faced by deaf individuals entering substance abuse treatment and following discharge

Several barriers can frustrate a deaf individual's intention to enter a substance abuse treatment program. Because few specialized programs work with the Deaf, it is difficult to determine the factors that influence a deaf individual's desire to maintain sobriety following completion of a residential treatment program. A sample of 100 individuals was drawn from the Minnesota Chemical Dependency Program for Deaf and Hard of Hearing Individuals, a model hospital-based inpatient treatment program. The study participants were asked to complete pretreatment and posttreatment surveys upon admission and discharge, respectively, in addition to a follow-up survey, to help determine which background factors might be associated with different treatment outcomes for deaf and hard of hearing persons who completed treatment in the program. Results are presented for the pretreatment and posttreatment assessments, and for the follow-up survey. Study limitations are discussed and recommendations are given for future treatment programs serving deaf and hard of hearing individuals.
