Attachment and individuation of deaf/hard-of-hearing and hearing young adults

This study examined differences between deaf/hard-of-hearing (D/HH) and hearing persons with regard to two interrelated and continuous developmental processes: attachment (Bowlby, 1969) and individuation (Mahler, 1963). The study also examined intergroup differences in two personal variables assumed to be influenced by these processes: self-esteem and well-being. Participants comprised 38 D/HH and 42 hearing persons aged 18 to 35 years from middle and upper-middle socioeconomic classes. All the D/HH participants had graduated from mainstreamed educational programs. Findings showed that D/HH participants expressed more fear of attachment and more fear of individuation than did hearing participants. D/HH participants also revealed a lower self-esteem and lower level of well-being compared to hearing participants. Higher fear of attachment correlated with lower levels of self-esteem and well-being. Results supported the theorized relationships between attachment and individuation processes and between these two processes and personality characteristics such as self-esteem and well-being.     

Attachment in deaf mothers and their children

In attachment research, there has been a growing interest in how adults conceptualize their relationships with their own parents as well as in the transmission of attachment status from parent to child and the variables that influence that transmission. The primary goal of the present study was to examine the transmission of attachment from deaf mother to child. Adult Attachment Interviews were collected on 32 deaf women and Strange Situation Procedure data were obtained from their children. While the distribution of deaf mother attachment classifications was similar to that found with hearing samples, the concordance between mother and child in terms of attachment status was lower than in hearing samples. Having a deaf parent did not affect a deaf adult's attachment status. Post hoc analyses suggested a trend towards a dismissing stance in attachment relationships. Results are discussed in terms of variables affecting attachment status as well as the transmission of attachment.     

Perceived stress among deaf adults

THE PRESENT ARTICLE describes the effectiveness of stress management classes in decreasing perceived stress among Deaf adults. Deaf adults may experience unique stressors, in addition to circumstances associated with increased stress in the general population. The Perceived Stress Scale (S. Cohen, Kamarck, and Mermelstein, 1983) was used as a pretest and posttest measure for participants in a study of the Deaf Heart Health Intervention. Results indicated that (a) some Deaf adults may have higher levels of perceived stress than the general population, and (b) culturally appropriate stress management interventions are promising as a means of assisting Deaf adults to decrease levels of perceived stress, and hence decrease risk for stress-related illnesses. Future research will focus on obtaining a larger, more diverse sample of Deaf adults and refining the intervention for maximum effectiveness.     

The hands have it: number representations in adult deaf signers

This study examines a wide range of numerical representations (i.e., quantity, knowledge of multiplication facts, and use of parity information) in adult deaf signers. We introduce a modified version of the number bisection task, with sequential stimulus presentation, which allows for a systematic examination of mathematical skills in deaf individuals in different modalities (number signs in streaming video vs. Arabic digit displays). Reaction times and accuracy measures indicated that deaf signers make use of several representations simultaneously when bisecting number triplets, paralleling earlier findings in hearing individuals. Furthermore, some differences were obtained between the 2 display modalities, with effects being less prominent in the Arabic digit mode, suggesting that mathematical abilities in deaf signers should be assessed in their native sign language.     

Mental health in deaf adults: symptoms of anxiety and depression among hearing and deaf individuals

Individuals with disabilities encounter practical and social problems beyond those experienced by nondisabled individuals. This extra burden may in turn increase the risk of developing mental health problems. The objective of this article is to disclose the mental health situation among deaf individuals compared to a control sample of hearing individuals. The analyses are based on two separate Norwegian postal surveys, one among the general population (1995-1997) and one among the deaf population (2001). A shortened version of the Hopkins Symptom Checklist was used to disclose the degree of mental distress among the respondents. Three questions common to the studies were analyzed to determine differences between the two groups. Analyses revealed that the deaf respondents showed significantly more symptoms of mental health problems than the hearing respondents. The results point to the need for focussing more attention on the mental health of deaf children and adults. Society must be made aware of the special risks that deaf children and adults encounter with respect to mental health.     

Parent bonding in clinically depressed deaf and hard-of-hearing adults

This study assessed the relationships between parent communication variables and the parent bonding factors of care and overprotection using a sample of 38 deaf and hard-of-hearing individuals connected with mental health services who had DSM-III-R or DSM-IV diagnoses of depression-related disorders. The 22 therapists working with these individuals also contributed to data collection. Results based on revised depression (BDI-R) and parent bonding (PBI-R) questionnaires, together with background data from both clients and therapists, indicate that higher ratings of depression are associated with less perceived care by mother and greater perceived overprotection by both mother and father. Paternal care and overprotection were negatively correlated, as were maternal care and overprotection. In comparison to hard-of-hearing counterparts, deaf participants were less depressed and had more positive ratings of communication with their parents. The BDI-R scores positively and significantly correlated with coded severity of diagnosis. Due to the small sample size, findings are suggestive. Further study is warranted.     

Language development in deaf children's interactions with deaf and hearing adults: a Dutch longitudinal study

The language development of two deaf girls and four deaf boys in Sign Language of the Netherlands (SLN) and spoken Dutch was investigated longitudinally. At the start, the mean age of the children was 3;5. All data were collected in video-recorded semistructured conversations between individual children and deaf and hearing adults. We investigated the lexical richness and syntactic complexity of the children's utterances in SLN and spoken Dutch, as well as language dominance and interactional participation. Richness and complexity increase over time, as well as children's participation. An important outcome is that syntactic complexity is higher in utterances with both sign and speech. SLN does not have higher outcomes on richness or complexity, but is dominant in terms of frequency of use.     

Incidental word learning in a hearing child of deaf adults

It is unclear how children develop the ability to learn words incidentally (i.e., without direct instruction or numerous exposures). This investigation examined the early achievement of this skill by longitudinally tracking the expressive vocabulary and incidental word-learning capacities of a hearing child of Deaf adults who was natively learning American Sign Language (ASL) and spoken English. Despite receiving only 20% of language input in spoken English, the child's expressive vocabularies at 16 and 20 months of age, in each language, were similar to those of monolingual age-matched peers. At 16 months of age, the child showed signs of greater proficiency in the incidental learning of novel ASL signs than she did for spoken English words. At 20 months of age, the child was skilled at incidental word learning in both languages. These results support the methodology as it applies to examining theoretical models of incidental word learning. They also suggest that bilingual children can achieve typical vocabulary levels (even with minimal input in one of the languages) and that the development of incidental word learning follows a similar trajectory in ASL and spoken English.     

Phonological representations in deaf children: rethinking the "functional equivalence" hypothesis

The sources of knowledge that individuals use to make similarity judgments between words are thought to tap underlying phonological representations. We examined the effects of perceptual similarity between stimuli on deaf children's ability to make judgments about the phonological similarity between words at 3 levels of linguistic structure (syllable, rhyme, and phoneme). Manipulation of stimulus contrasts (acoustic, visual/orthographic, tactile/motoric) allowed a finer-grained estimate of the sources of knowledge that deaf individuals use to make similarity judgments between words. The results showed that the ability to make syllable-, rhyme-, and phoneme-level judgments was not tied to "phonological" facilitation when these conditions are contrasted. These findings are inconsistent with long-held assumptions of "functional" equivalence between "heard" and "seen" speech in the development of phonological representations in deaf learners. We argue that previous studies reporting evidence for phonological effects in similarity judgments have failed to sufficiently control for alternative sources of sensory information, namely, visual and tactile/motoric.     

The use of graphic representations of sign language in leveled texts to support deaf readers

The study considered whether adding sign language graphics to the books being used for reading instruction in a first-grade classroom would promote the literacy development of students who are deaf or hard of hearing. The researchers also sought to discover whether materials existed to put the process of modifying leveled texts within the reach of the typical classroom teacher, in terms of cost and procedure. Students' reading behaviors seemed to indicate that the presence of sign graphics supported their development as readers. The materials needed to create sign support for the English print in the leveled books were commercially available.     

Multigenerational perceptions of mental health services among deaf adults in Florida

The objective of the study was to better understand the perceptions and needs of multigenerational Deaf adults related to mental health services. A survey sampled participants who were between 20 and 85 years old and Deaf. Questions were developed to identify the perspectives of Deaf adults related to the availability of mental health services, preferences for these services, and current utilization of services. Participants were grouped into age (years) categories: young adult (18-34), middle adult (35-54), older adult (55-65), and oldest (66-). Category response trends were examined using chi-square analysis. The analysis showed significant differences in the preferences and utilization of mental health care. These data also suggested preferences for service delivery. These data indicate areas of importance related to the development of programs and services for Deaf adults and to indicate where funding for services would be best utilized.     

Developing a standardized comprehensive health survey for use with deaf adults

THERE IS LIMITED INFORMATION on how communication barriers impact on the health of deaf individuals. The present article describes the development of a standardized interview tool to collect health-related information from deaf adults via face-to-face interviews in American Sign Language (ASL). Questions were selected largely from existing standardized questionnaires. Key steps in standardizing the instrument included the creation of an ASL gloss version of the survey and extensive interviewer training. The instrument was pilot-tested and revised prior to implementation. There were 139 questions on the final instrument. A total of 203 interviews were conducted between November 2002 and March 2003. A standardized interview survey administered in ASL proved an effective and well-accepted means of collecting health-related information from a diverse sample of deaf individuals. Several challenges were encountered throughout the process, and the resulting lessons will be useful to future research efforts.     

Differences in arithmetic subtraction of nonsymbolic numerosities by deaf and hearing adults

Previous research has demonstrated that both hearing adults and hearing children with no training in arithmetic successfully performed approximate arithmetic on large sets of elements. Here, the possibility is explored that the same phenomenon can be confirmed in deaf adults who have acquired a signed language as their first language. Results reveal that they can perform simple arithmetic subtraction on nonsymbolic numerosities. Their performance levels were even higher than those of hearing adults who participated in the experiment as a control group. On the other hand, the performance levels of subtraction of the deaf adults in the formal mathematics were lower than those of the hearing adults. The findings are argued in terms of the characteristics of cognitive capabilities the deaf adults acquired through their development.     

Smoking and deaf adults: associations with age at onset of deafness

Smoking is a major health problem whose prevalence in different populations is thought to be influenced by sociocultural and linguistic factors. Although smoking and hearing loss are positively correlated, little is known about the smoking habits of deaf populations. Using national survey data, this study determined the smoking prevalence in two socioculturally distinct deaf populations, based on age at onset of deafness. The smoking prevalence in each deaf population was compared to the smoking prevalence in the hearing population in multivariate analyses that adjusted for sociodemographics and health status. The smoking prevalence among postlingually deafened adults was not significantly different from that among hearing adults. Prelingually deafened adults were found to be less likely to smoke than hearing adults, even though they have less education and lower income, factors both associated with higher smoking prevalence in other populations. The lower smoking prevalence among prelingually deafened adults may be due to cultural differences or to limited access to English-language tobacco advertising.     

Theory of mind in deaf adults and the organization of verbs of knowing

Naive theories of mind provide an organizing scheme for concept formation and categorization. Additionally, they highlight what is important within a domain. This study investigated how deaf adults with hearing parents orgaize 17 cognitive verbs of knowing as a way of describing their naive theory of mind. Deaf adults rated on 1 to 7 scale the similarity of pairs of cognitive verbs in terms of whether 'the words are alike or different based on how you would use your mind when you do that mental activity'. We directly compared the similarity of cognitive verbs in these deaf adults with data collected in earlier research describing the organisation of cognitive verbs in hearing adults. We conducted multidimensional scaling, additive similarity tree, and Pathfinder analyses to assess global, categorical, and local relations in the domain. Deaf adults' theory of mind revealed distinction among mental verbs in terms of information-processing components and constructive certainty components. In all analyses, the deaf group showed a very similar organization to that of hearing adults examined in previous research. We conclude that, although deaf adults might be expected to view congnitive processes differently than hearing adults, they nonetheless exhibit a theory of mind that is highly similar to that of hearing adults.
