RESUMEN

BACKGROUND: People who are d/Deaf face challenges when communicating with pharmacists, especially during medication counseling. AIM: This study aimed to explore and understand the perceptions and experiences of d/Deaf people regarding medication counseling by hospital pharmacists. METHOD: Five sets of semi-structured in-depth interviews (44 total) and one focus group were conducted among d/Deaf people, hospital pharmacists, and Thai sign language (TSL) interpreters. Data from d/Deaf people's perspectives were triangulated with data from pharmacists and TSL interpreters. RESULTS: Five themes emerged from the interview: (1) d/Deaf people believe that deafness is stigmatized, (2) d/Deaf people's needs during medication counseling, (3) skills for d/Deaf people to communicate with pharmacists, (4) values identified in d/Deaf people, 5) emotions related to medication counseling with pharmacists. Effort, trust, confidentiality, and privacy were values associated with counseling. d/Deaf people preferred communicating with pharmacists in TSL to communicating with pharmacists via TSL interpreters because of trust and confidentiality. They also preferred pharmacists with d/Deaf knowledge and skills. Moreover, d/Deaf people believed that deafness was stigmatized, so signing in nonprivate areas was embarrassing. When TSL was not used in communication, language, lipreading, and technology skills became important. With these non-TSL communications, d/Deaf people may not have understood the conversation. However, they may not have asked pharmacists because they felt Krengjai (the hesitancy to bother). CONCLUSION: Thai d/Deaf people have negative experiences during medication counseling. Skills and emotions can act as barriers to communication with pharmacists. TSL should be used to improve d/Deaf people's experiences during medication counseling.

RESUMEN

INTRODUCTION: Healthcare information resources are extremely limited currently in Irish Sign Language and studies of the preferred methods of gaining information in the Deaf and hard of hearing (DHH) community are scarce. This study aims to explore the opinions of DHH people on an information portal designed for a radiology department, taking account of their preferred methods of gaining information and past experiences of participants that may be addressed by a portal of this kind. These opinions inform the overall objective of creating a template for further improvements to the portal. METHODS: An information portal containing what to expect before, during and after a chest x-ray examination was created. Ethical approval was granted to interview 11 DHH adults via zoom and in person to explore their opinions of an information portal's value prior to chest x-ray examinations. The preferred media type for obtaining information prior to x-ray examinations was also explored. Interview methods reflected the heterogeneity of DHH people's communication methods. Transcripts of the study were analysed using qualitative thematic analysis. RESULTS: The resultant themes from the study were; positives of the information portal as it stands, feelings, pitfalls of the information portal, accessibility considerations, d/Deaf awareness, previous issues that may be helped by the information portal, improvement suggestions and further developments. The majority of participants preferred the subtitled video over other media types. Participants felt they would have been better prepared for their x-ray if they had used the information portal prior, and it would have increased their ability to give informed consent. Participants highlighted experiences of audism in radiology departments and cited the need for healthcare worker's deaf awareness to be improved. Improvements to the information portal were provided by participants. CONCLUSION: The idea of this information portal was supported by the participants. Increased deaf awareness particularly in healthcare workers will improve this resource and improve patient experiences in radiology. IMPLICATIONS FOR PRACTICE: A national policy is needed to implement accessible information in radiology departments to improve the provision of medical autonomy. This policy should be supported by ISL interpreters.

RESUMEN

Evidence is lacking on the impact of bilingualism on the speech skills of children with cochlear implants (CIs). This study described the speech production of children with CIs acquiring French and one or more additional spoken languages. Four groups of children aged 4-11 were included: bilinguals (n = 15) and monolinguals (n = 14) with CIs and bilinguals (n = 14) and monolinguals (n = 20) with typical hearing. Data were collected about the percentage of consonant correct (PCC) and vowel correct (PVC) produced in French and intelligibility in all languages they spoke. Bilingual and monolingual children with CIs had comparable speech accuracy in French, but the pattern differed, impacting PCC for bilinguals and PVC for monolinguals. Most children with CIs had accurate and intelligible speech in French, but few bilingual children with CIs were highly intelligible in their home language. Therefore, bilingualism did not impede the speech production outcomes of bilingual children with CIs in the language of the wider community.

RESUMEN

Recent studies suggest that benefiting early from both a cochlear implant (CI) and exposure to cued speech (CS, support system for the perception of oral language) positively impacts deaf children's speech perception, speech intelligibility, and reading. This study aims to show how: 1/CS-based speech perception ("cue reading"), and speech intelligibility might also constitute precise measures for determining the impact of CI and CS on deaf students' literary performance; 2/print exposure might also be a predictive factor in this equation. We conducted regression analyses to examine the impact of these three variables in two experiments conducted on Grade 2-3 deaf children and Grade 6-9 deaf adolescents. Results indicate print exposure significantly contributes to literacy skills across experiments, with additional contributions from cue reading and speech intelligibility in older students. The predictive aspect of the print exposure, cue reading, and speech intelligibility variables will be discussed, as will the consequences for educational and pedagogical practices.

RESUMEN

Some species have evolved the ability to use the sense of hearing to modify existing vocalizations, or even create new ones, which enlarges their repertoires and results in complex communication systems.1 This ability corresponds to various forms of vocal production learning that are all possessed by humans and independently displayed by distantly related vertebrates.1,2,3,4,5,6,7 Among mammals, a few species, including the Egyptian fruit bat,8,9,10 would possess such vocal production learning abilities.7 Yet the necessity of an intact auditory system for the development of the Egyptian fruit bat typical vocal repertoire has not been tested. Furthermore, a systematic causal examination of learned and innate aspects of the entire repertoire has never been performed in any vocal learner. Here we addressed these gaps by eliminating pups' sense of hearing at birth and assessing its effects on vocal production in adulthood. The deafening treatment enabled us to both causally test these bats' vocal learning ability and discern learned from innate aspects of their vocalizations. Leveraging wireless individual audio recordings from freely interacting adults, we show that a subset of the Egyptian fruit bat vocal repertoire necessitates auditory feedback. Intriguingly, these affected vocalizations belong to different acoustic groups in the vocal repertoire of males and females. These findings open the possibilities for targeted studies of the mammalian neural circuits that enable sexually dimorphic forms of vocal learning.

RESUMEN

PURPOSE: This study aimed to investigate antenatal depression and drug use among deaf and hard-of-hearing (DHH) birthing parents who use American Sign Language (ASL), spoken English, or bilingually both ASL and English. METHODS: DHH participants in the United States responded to the Survey on Pregnancy Experiences of Deaf and Hard-of-Hearing Women. Respondents self-reported their antenatal depression diagnoses and drug use (i.e., pain relievers, cannabis, or illicit drugs) during their last pregnancy. Poisson regression models were used to estimate prevalence ratios, adjusting for age, race/ethnicity, education, marital status, and parity. RESULTS: The average age of respondents (n = 587) was 35 years. Respondents were predominantly non-Hispanic white (80%), college educated (60%), and married (74%). Relative to DHH English-speakers, DHH ASL-users had lower prevalence of reporting antenatal depression diagnosis (aPR = 0.40, 95% CI: 0.23 to 0.72). DHH people who reported antenatal depression diagnosis had higher prevalence of reporting antenatal drug use (PR = 2.34, 95% CI: 1.65 to 3.33). There were no significant associations between preferred language and antenatal drug use. CONCLUSIONS: DHH ASL-users are less likely to report receiving an antenatal depression diagnosis compared to DHH English-speakers. Given well-documented patient-provider communication barriers among DHH ASL-users, it is unclear if the lower prevalence observed in this study is the result of inadequate or inaccessible screening during pregnancy. Future work should consider universal use of linguistically appropriate screening tools for DHH birthing parents in both clinical and research settings.

RESUMEN

INTRODUCTION: Vocabulary knowledge is an essential element in language development. There is evidence of significant differences in vocabulary knowledge between deaf children and hearing peers of the same age. These differences put deaf students at a disadvantage when compared to their hearing counterparts. The aim of this study was to investigate whether certain types of words characterise the lexical difficulties of deaf students. Our starting point is that this knowledge is needed to design interventions that are adapted to the particular needs of these students for their lexical development. METHODS: We evaluated the lexical comprehension of 90 Spanish students. The sample comprised 45 hearing students and 45 students with severe or profound hearing loss. Both groups were attending the later years of primary school (8 to -12-year-olds). They were tested using the Spanish Peabody Picture Vocabulary Test-III. The performance of both groups was statistically compared using percentiles and standard scores as well as a selected set of words from the test. RESULTS: No significant differences between hearing and deaf groups were found by age, sex, and sociocultural level. Significant differences were found between groups in their percentile and standard scores. There were no significant differences in performance between the two groups on only five of the 25 words with the highest error rate in the deaf group. The qualitative analysis of the remaining 20 words that were especially challenging for deaf students reveals results of interest which could help guide interventions. CONCLUSIONS: The results indicate the need for lexical intervention for deaf students in the final years of primary school. The specialised support service for deaf learners should approach the intervention by targeting a specific type of vocabulary, making the semantic relationships between these words more transparent and promoting a deeper understanding of them.

RESUMEN

This study explores the narrative skills of deaf and hearing children within the context of Arabic diglossia, a linguistic environment characterised by significant differences between spoken dialects and formal written language. Using Stein and Glenn's (1979) and Bruner's (1991) frameworks, the research analyses the narrative constructions of 13 hearing and 13 deaf children in Kuwait. The findings reveal that hearing children, benefiting from consistent exposure to spoken and formal Arabic, produced more coherent and detailed narratives compared to deaf children. Hearing participants also demonstrated greater vocabulary diversity. Age-related improvements in narrative skills were more pronounced among hearing children, while the impact of sign language exposure on narrative abilities was significant among deaf children. The study underscores the critical role of early language exposure and educational support in fostering narrative development, particularly in a diglossic context. These findings highlight the need for specialised educational strategies to support the unique narrative development needs of deaf children.

RESUMEN

To better understand the individual differences in fairness, we used event-related potentials (ERPs) to explore the fairness characteristics of deaf college students through the ultimatum game task. Behaviorally, the significant main effect of the proposal type was found, which meant both deaf and hearing college students showed a lower acceptance rate for the more unfair proposal. Interestingly, we found a significant interaction between group and proposal type in the early stage (N1). Moreover, in the deaf college group, N1 (induced by moderately and very unfair proposals) was significantly larger than that of fair proposals. However, we found that deaf college students had smaller amplitudes on P2 and P3 than hearing college students. These results suggested that deaf college students might pursue more equity strongly so they are more sensitive to unfair information in the early stage. In a word, we should provide more fair allocations for deaf college students in our harmonious society.

RESUMEN

The face inversion effect is an important indicator of holistic face perception and reflects the developmental level of face processing. This study examined the face inversion effect in deaf or hard of hearing (DHH) children aged 7-17 using the face dimensions task. This task uses photographic images of a face, in which configural and featural information in the eye and mouth regions have been parametrically and independently manipulated. The study aimed to discuss the effect of face inversion on facial processing in DHH children, including two aspects of information processing types (configural versus featural) and processing regions (eyes versus mouth) and compared the results with hearing children. The results revealed that DHH children aged 7-17 years exhibit significant face inversion effect, with disruptions observed in both the featural and configural processing of eyes and mouths when faces were inverted. Configural processing was more affected by inversion than featural processing in all children, with larger differences observed in DHH children than in hearing children. This supports the dual-mode hypothesis of holistic face processing. Age correlations were observed in the sensitivity of DHH children to face inversion effect but not among hearing children. The inversion effect of configural mouth processing decreases with age in DHH children.

RESUMEN

Difficulties in monitoring reading comprehension result in poor comprehension. One key aspect of monitoring is metacomprehension, which refers to one's awareness of one's own reading comprehension. Previous studies have observed difficulties in metacomprehension among the deaf or hard-of-hearing (DHH) population. This study aims to determine whether the metacomprehension of DHH students corresponds to their reading score and whether they are truly capable of adjusting their metacomprehension to the difficulty of the text. We evaluated 25 Spanish-speaking DHH students with reading scores approximately equivalent to Grades 5 or 6 of Primary School. Participants were asked to read a text and answer questions. The texts corresponded to three levels of difficulty (explicit, inferable, and noninferable). The results revealed that the metacomprehension of DHH students corresponded to their reading score. The DHH population may have better reading metacomprehension than is typically assumed, although the manifestation of this skill may depend on the type of task demanded of them (comprehension judgment or knowledge judgment).

RESUMEN

OBJECTIVES: The purpose of this study was to investigate the reading outcomes of a Canadian cohort of school-aged deaf learners with cochlear implants (CIs). The goal was to investigate whether achievement approached that of hearing age peers and identify demographic factors influencing performance. METHODS: Participants represent a subset of 13 students with CIs from a larger sample of 70 deaf students in grades four through 12 educated in inclusive settings within a large school board in central Canada. Data sources included demographic information, teachers' ratings on the Categories of Auditory Performance (CAP), and scores from the Woodcock-Johnson III Diagnostic Reading Battery [WJ III-DRB].Results/Discussion: Participants performed within the low average range in all areas except for Phonological Awareness, which was in the low range; however, there was wide variability in scores across participants. None of the demographic variables (e.g. home language, additional disabilities) had a statistically significant association with performance, although older students had higher mean scores on the Phonological Awareness cluster. CONCLUSION: These findings add to the body of research on literacy achievement and cochlear implantation, providing evidence that this technology has a significant positive effect on outcomes for a population that has heretofore underperformed in this area.

RESUMEN

Neurodevelopmental disorders and sleep disturbances share genetic risk factors. DEAF1 genetic variants are associated with rare syndromes in which sleep disturbances are commonly reported, yet the specific sleep disorders in these patients, and the molecular mechanisms underlying this association, are unknown. We aimed to pinpoint specific biological processes that may be disrupted by pathogenic variants in this gene, comparing a list of DEAF1 regulatory target genes with a list of insomnia-associated genes, and using the intersect gene list as the input for pathway enrichment analysis. Thirty-nine DEAF1 regulatory targets were also identified as insomnia-associated genes, and the intersecting gene list was found to be strongly associated with immune processes, ubiquitin-mediated proteolysis pathways and regulation of the cell cycle. This preliminary study highlights pathways that may be disrupted by DEAF1 pathogenic mutations and might be putative factors underlying the manifestation of insomnia in patients harboring such variants.

RESUMEN

STEM education for deaf students aims to engage and include intellectual and experiential learning other than normal classrooms. These programs improve students' critical thinking, problem-solving, creativity, and complex decision-making, which are essential for academic and life success. This study aims to explore several aspects of a STEM based workshop including problem solving skills, STEM skills, subject knowledge, and effectiveness of the workshop for a group of 27 deaf students. The workshop spanned five consecutive days and focused on problem-solving principles within the context of global warming. Moreover, in this study, the Creative Problem-solving approach developed by Osborn and Parnes was implemented to measure improvement of the constructs above, through a post questionnaire. Cronbach's alpha and McDonald's Omega coefficient exceeded .7 for each construct. The data obtained from the questionnaire demonstrated a random distribution of data according to the Shapiro-Wilk test performed (p < 0.05), leading to the use of non-parametric analysis tools. The results based on the non-parametric test analysis (Kruskal Wallis test) show that high school students' problem-solving abilities improved despite the data's randomness (Mean rank = 16.72). The workshop was enhanced for the Preparatory students, who tended to gain more STEM skills and problem-solving abilities from it (Mean rank = 14.75). It also improved the knowledge and STEM skills of Primary-stage students (Mean rank = 18.13 and 18.06, respectively). This study contributes to the existing body of literature by examining how addressing challenges of global warming can enhance various abilities among deaf students.

RESUMEN

Many children with profound hearing loss have received cochlear implants (CI) to help restore some sense of hearing. There is, however, limited research on long-term neurocognitive outcomes in young adults who have grown up hearing through a CI. This study compared the cognitive outcomes of early-implanted (n = 20) and late-implanted (n = 21) young adult CI users, and typically hearing (TH) controls (n=56), all of whom were enrolled in college. Cognitive fluidity, nonverbal intelligence, and American Sign Language (ASL) comprehension were assessed, revealing no significant differences in cognition and nonverbal intelligence between the early and late-implanted groups. However, there was a difference in ASL comprehension, with the late-implanted group having significantly higher ASL comprehension. Although young adult CI users showed significantly lower scores in a working memory and processing speed task than TH age-matched controls, there were no significant differences in tasks involving executive function shifting, inhibitory control, and episodic memory between young adult CI and young adult TH participants. In an exploratory analysis of a subset of CI participants (n = 17) in whom we were able to examine crossmodal plasticity, we saw greater evidence of crossmodal recruitment from the visual system in late-implanted compared with early-implanted CI young adults. However, cortical visual evoked potential latency biomarkers of crossmodal plasticity were not correlated with cognitive measures or ASL comprehension. The results suggest that in the late-implanted CI users, early access to sign language may have served as a scaffold for appropriate cognitive development, while in the early-implanted group early access to oral language benefited cognitive development. Furthermore, our results suggest that the persistence of crossmodal neuroplasticity into adulthood does not necessarily impact cognitive development. In conclusion, early access to language - spoken or signed - may be important for cognitive development, with no observable effect of crossmodal plasticity on cognitive outcomes.

RESUMEN

This meta-analysis summarizes evidence from 44 neuroimaging experiments and characterizes the general linguistic network in early deaf individuals. Meta-analytic comparisons with hearing individuals found that a specific set of regions (in particular the left inferior frontal gyrus and posterior middle temporal gyrus) participates in supramodal language processing. In addition to previously described modality-specific differences, the present study showed that the left calcarine gyrus and the right caudate were additionally recruited in deaf compared with hearing individuals. In addition, this study showed that the bilateral posterior superior temporal gyrus is shaped by cross-modal plasticity, whereas the left frontotemporal areas are shaped by early language experience. Although an overall left-lateralized pattern for language processing was observed in the early deaf individuals, regional lateralization was altered in the inferior frontal gyrus and anterior temporal lobe. These findings indicate that the core language network functions in a modality-independent manner, and provide a foundation for determining the contributions of sensory and linguistic experiences in shaping the neural bases of language processing.

RESUMEN

OBJECTIVES: Communication breakdowns and their repair by deaf and hard-of-hearing (DHH) and hearing adolescents were examined in conversation with an unfamiliar communication partner. METHOD: This study compared the number and type of clarification requests and responses to those requests of 16 DHH and 16 normal-hearing adolescents aged 11-16 years, in a 10-minute conversation with an unfamiliar adult. It also analyzed the relationship between speech intelligibility, communication breakdowns, and clarification requests by an unfamiliar adult. the Children's Communication Checklist (CCC) was completed by parents. RESULTS: DHH adolescents demonstrated significantly higher usage of nonverbal clarification requests and verbal and nonverbal responses to clarification requests compared to normal-hearing adolescents in conversations with an unfamiliar adult. Furthermore, the subscale scores of the CCC and the speech intelligibility of DHH adolescents were significantly lower than those of normal-hearing adolescents. There were correlations between speech intelligibility and the speech subscale score of the CCC, as well as correlations between the pragmatic composite score of the CCC, the number of communication breakdowns, and the number of clarification requests by an unfamiliar adult. DISCUSSION: The adolescents with DHH experienced more communication breakdowns in conversation with an unfamiliar adult and the number of clarification requests made by adults was higher.

RESUMEN

The matter of raising and educating deaf children has been caught up in percepts of development that are persistently inaccurate and at odds with scientific research. These percepts have negatively impacted the health and quality of life of deaf children and deaf people in general. The all too prevalent advice is to raise the child strictly orally and wait to see what happens. Only when the child is seriously behind is a completely accessible language - a sign language - introduced, and that is far too late for protecting cognitive health. The medical profession, along with others, needs to offer parents better advice and better supports so that neither the children nor their parents wait and watch as the oral-only method fails. All must take responsible action to assure an approach that succeeds.

RESUMEN

This study investigated Cantonese and Hong Kong Sign Language (HKSL) phonological activation patterns in Hong Kong deaf readers using the ERP technique. Two experiments employing the error disruption paradigm were conducted while recording participants' EEGs. Experiment 1 focused on orthographic and speech-based phonological processing, while Experiment 2 examined sign-phonological processing. ERP analyses focused on the P200 (180-220 ms) and N400 (300-500 ms) components. The results of Experiment 1 showed that hearing readers exhibited both orthographic and phonological effects in the P200 and N400 windows, consistent with previous studies on Chinese reading. In deaf readers, significant speech-based phonological effects were observed in the P200 window, and orthographic effects spanned both the P200 and N400 windows. Comparative analysis between the two groups revealed distinct spatial distributions for orthographic and speech-based phonological ERP effects, which may indicate the engagement of different neural networks during early processing stages. Experiment 2 found evidence of sign-phonological activation in both the P200 and N400 windows among deaf readers, which may reflect the involvement of sign-phonological representations in early lexical access and later semantic integration. Furthermore, exploratory analysis revealed that higher reading fluency in deaf readers correlated with stronger orthographic effects in the P200 window and diminished effects in the N400 window, indicating that efficient orthographic processing during early lexical access is a distinguishing feature of proficient deaf readers.
