Executive functioning and nonverbal cognitive factors associated with response to technology-assisted language intervention

ObjectiveTo explore potential differences in the relationship between executive function (EF) skills and language development when integrating augmentative and alternative communication technology into speech-language therapy for deaf/hard of hearing (DHH) children. MethodRandomized trial data were analysed to investigate this relationship among children who participated in a Technology-Assisted Language Intervention (TALI) compared to treatment as usual (TAU). Language samples were assessed for pre-post-intervention changes, including mean length of utterance in morphemes (MLU), mean turn length (MTL), and number of different words spoken (NDW). EF skills were measured with standardized parent-report assessment. ResultsThirty-seven DHH children were included (TALI n = 19 and TAU n = 18). Results of regression models indicated that higher EF skills were significantly (p < 0.05) associated with improvements in MLU, MTL, and NDW among children who received TAU. No significant associations between EF skills and any of the measures (MLU, MTL, NDW) were seen in children who received TALI. ConclusionThese results suggest that TALI may offer language learning support, particularly for DHH children with EF difficulties. Future research should investigate the direct relationship between EF measurements and language outcomes in TALI recipients. Establishing baseline EF measurements in DHH children could inform personalized strategies within language interventions and therapy.

Exploring the SoundVizVR Plugin in the Development of Sound-Accessible Virtual Reality Games: Insights from Game Developers and Players

Based on a virtual reality (VR) sound visualization indicator system named “SoundVizVR” proposed and evaluated in previous research, we developed a plugin for the Unity platform, enabling developers to adopt the SoundVizVR system in their VR applications and games. Next, we worked with two VR game developers to explore the usability of the plugin and how it impacted the view on accessibility from the game developers’ perspectives. The developers used the plugin for one week to integrate it into their current projects or design new games with the plugin. Then, we recruited ten Deaf or Hard-of-Hearing (DHH) participants and five hearing participants to play the two developed VR games to evaluate the user experience and effectiveness of the SoundVizVR system in advancing audio accessibility in VR games. According to the findings of the study process, we provide game design practices for making sounds in VR games accessible and suggestions on optimizing the developers’ and players’ experiences of a sound accessibility plugin for the Unity platform.

Does Childhood Cochlear Implantation Spill Over to Carers' Employment Status?

Carers of children with disabilities, especially primary carers, tend to have poorer labor market outcomes than carers of typically developing children. However, the extant literature has been largely silent on whether interventions for children's disabilities spill over to carers' employment outcomes, if at all. We aimed to fill this gap. We analyzed data from the Longitudinal Outcomes of Children with Hearing Impairment study, which is a unique panel dataset of Australian children who are deaf or hard-of-hearing (DHH). The Longitudinal Outcomes of Children with Hearing Impairment dataset includes information about 449 DHH children. We used 3 waves covering the same children at ages 0 to 3, 5 to 7, and 8 to 10 years during 2005 and 2018. We used a panel random-effects model, the use of which was supported by the Hausman specification test to control for time-invariant individual heterogeneity. We found that primary carers (typically mothers) of DHH children with cochlear implants (CI) were more likely to be employed relative to DHH children without a CI. The positive association was stronger among carers from a lower socioeconomic background. The association between childhood CI and carer employment may potentially be due to relaxed primary carers' time constraints to care for the child, increased self-efficacy, and reduced carer stress, enabling them to engage in other activities, including employment. Further research through large-scale, longitudinal studies is warranted to solidify the findings of this research.

Applied Research in Clinical Audiology with Spanish Speakers in the United States: A Scoping Review.

The Hispanic population is growing, and Spanish is the second most spoken language in the United States. When individuals experience a hearing problem, culturally and linguistically responsive services represent an important part of person-centered care, contributing to wellbeing and intervention outcomes. The purpose was to identify research in clinical audiology conducted with Spanish speakers to illuminate gaps and inform future research. A scoping literature review. A database search was completed in January 2022. Included research was conducted in clinical audiology, had Spanish-speaking deaf or hard-of-hearing (DHH) adults/parents of a DHH child in the United States, Spanish language data collection, and published in English in a peer-reviewed journal. Studies were categorized by the area of audiology and a narrative description provided. The search identified 655 articles. Following screening, 11 studies met the inclusion criteria and 1 article was identified from the reference lists of included articles for a total 12 articles. The articles were published between 1997 and 2021. Most studies were conducted with adults and a few were with parents of DHH children. Research was conducted in four areas: hearing loss experiences, hearing aid experiences, hearing screening, and communication. There is limited research with Spanish-speaking DHH individuals and parents of DHH children. There is an urgent need for future research to inform culturally and linguistically responsive clinical practice, and to provide evidence-based interventions for effective hearing health care management.

An investigation on the face inversion effect in deaf children.

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 7-17years 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.

Reading metacomprehension of Spanish deaf and hard-of-hearing students.

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).

Teletherapy to address language disparities in deaf and hard-of-hearing children: study protocol for an inclusive multicentre clinical trial

IntroductionChildren who are deaf or hard-of-hearing (DHH) are at risk for speech and language delay. Language outcomes are worse in DHH children from lower socioeconomic backgrounds, due in part to...

Comparing Deaf/Hard-of-Hearing Children's Oral Narratives Using Movies and Static Books.

Clinicians utilize various methods for narrative sampling, including oral assessments like story generation and retelling, often aided by visual aids. Assessing language skills in deaf/hard of hearing (DHH) children requires careful narrative technique selection. This comparative observational study investigates the narrative outcomes of story generation and retelling tasks in 21 DHH children, using both book and movie contexts. Most microstructural elements (except for the mean length of utterance) were similar across the book and movie conditions. Differences in word choice, such as the use of action verbs, were evident. Macrostructural differences between book and movie conditions were insignificant regarding story grammar elements. However, movies, being visually engaging, potentially enhance the inclusion of characters, settings, plot, and actions. This research illuminates narrative assessment considerations, emphasizing technology's role in enhancing options for assessment for DHH children.

The role of grit in thinking styles and academic major satisfaction.

Satisfaction with one's academic major is critical to a university student's development. This study explores the interrelationships among thinking styles, grit, and academic major satisfaction in both deaf or hard-of-hearing (DHH) and hearing students, employing independent samples t-tests to compare the two groups, Pearson's correlation analysis to explore relationships among the variables, and mediation analysis to understand the mediating effect of grit on the relationship between thinking styles and academic major satisfaction. The results indicated significantly higher levels of grit and consistency of interest in DHH students than hearing students, with no significant differences in perseverance of effort. A strong correlation was found between thinking styles and both grit and academic major satisfaction, particularly in DHH students. Mediation analysis revealed that grit significantly mediated the relationship between thinking styles and academic major satisfaction, underscoring its role in enhancing students' academic experience. These findings contribute to the limited literature on DHH students' psychological attributes and the complex interplay of psychological constructs in academic major satisfaction, offering valuable insights for tailored educational strategies.

Cross-modal digit span and vocabulary proficiency in deaf or hard-of-hearing children.

This study aims to examine the relationship between vocabulary proficiency and short-term memory capacity in deaf or hard-of-hearing (DHH) children. We test the hypothesis that the relationship between vocabulary skills and digit span performance could be strengthened when the digit span task encompasses cross-modal integration processes. A group of DHH children performed two types of auditory digit span tasks. Furthermore, they participated in a standardized vocabulary proficiency test, comprising two subtests: Receptive Vocabulary and Expressive Vocabulary. The verbal digit span served as a significant predictor of Expressive Vocabulary among the DHH children. Simultaneously, the auditory-pointing digit span accounted for a substantial portion of performance variation in both Receptive and Expressive Vocabulary. After considering the impact of the duration of auditory-verbal intervention through regression models, likelihood ratio tests demonstrated that the auditory-pointing digit span persisted as a significant determinant of both receptive and expressive vocabulary skills. A positive influence of the intervention was also confirmed by the present results. This study provides evidence that memory span and the ability to integrate cross-modal information could serve as significant cognitive correlates of vocabulary proficiency in DHH children.

Geographic, Sociodemographic, and Clinical Factors Associated With Parental Self-Efficacy in Pediatric Patients With Hearing Loss.

To identify geographic, sociodemographic, and clinical factors associated with parental self-efficacy in a diverse cohort of deaf or hard-of-hearing (DHH) children. Cross-sectional study. Tertiary children's hospital. Four hundred forty parents of DHH children aged 0 to 17 completed the 25-item Scale of Parental Involvement and Self-Efficacy (SPISE) survey from 2014 to 2022. Residential addresses were geocoded and assigned Area Deprivation Index and Social Vulnerability Index rankings, and univariable and multivariable analyses were conducted using sociodemographic and clinical variables, including sex, race/ethnicity, insurance type, survey language, age at the survey, comorbidities, newborn hearing screening results, and hearing loss laterality and severity. Compared to English and Spanish-speaking parents, Chinese-speaking parents were associated with overall lower parental self-efficacy and involvement (regression coefficient = -0.518, [-0.929, -0.106]), Cohen's d = 0.606) and lower scores on items related to their ability to affect multiple aspects of their child's development and expression of thoughts as well as competency in checking and putting on their child's sensory device. Across univariable and multivariable analyses, besides Chinese language, all other sociodemographic, clinical, and geographic variables were not associated with SPISE score. To achieve the best patient outcomes, care teams can use the SPISE to evaluate parental self-efficacy and provide targeted support to parents at risk for having lower knowledge and confidence scores about critical skills necessary to facilitate their child's auditory access and language development. Notably, this study found similar reports of parental efficacy across various sociodemographic, clinical, and geographic variables but significantly lower SPISE scores in Chinese-speaking families.

Two are better than one: Differences in cortical EEG patterns during auditory and visual verbal working memory processing between Unilateral and Bilateral Cochlear Implanted children

Despite the proven effectiveness of cochlear implant (CI) in the hearing restoration of deaf or hard-of-hearing (DHH) children, to date, extreme variability in verbal working memory (VWM) abilities is observed in both unilateral and bilateral CI user children (CIs). Although clinical experience has long observed deficits in this fundamental executive function in CIs, the cause to date is still unknown. Here, we have set out to investigate differences in brain functioning regarding the impact of monaural and binaural listening in CIs compared with normal hearing (NH) peers during a three-level difficulty n-back task undertaken in two sensory modalities (auditory and visual). The objective of this pioneering study was to identify electroencephalographic (EEG) marker pattern differences in visual and auditory VWM performances in CIs compared to NH peers and possible differences between unilateral cochlear implant (UCI) and bilateral cochlear implant (BCI) users. The main results revealed differences in theta and gamma EEG bands. Compared with hearing controls and BCIs, UCIs showed hypoactivation of theta in the frontal area during the most complex condition of the auditory task and a correlation of the same activation with VWM performance. Hypoactivation in theta was also observed, again for UCIs, in the left hemisphere when compared to BCIs and in the gamma band in UCIs compared to both BCIs and NHs. For the latter two, a correlation was found between left hemispheric gamma oscillation and performance in the audio task. These findings, discussed in the light of recent research, suggest that unilateral CI is deficient in supporting auditory VWM in DHH. At the same time, bilateral CI would allow the DHH child to approach the VWM benchmark for NH children. The present study suggests the possible effectiveness of EEG in supporting, through a targeted approach, the diagnosis and rehabilitation of VWM in DHH children.

How to Improve Grit Among Deaf or Hard of Hearing Students: The Effect of Thinking Style.

The researchers examined the associations between thinking styles and grit. A cross-sectional design was adopted, with two weeks of data collection. The Thinking Styles Inventory-Revised II and the Grit Scale were administered to 365 signing deaf or hard-of-hearing (DHH) Arts and Design students and 443 hearing university students in mainland China. CFA, MANOVA, hierarchical multiple regression analyses, and a multi-group analysis were executed for data analysis. DHH and hearing students with Type I styles (i.e., more creativity-generating, less structured, and cognitively more complex) had higher grit levels, with large effect sizes for the identified relationships. There were no differences in the relations for either group. The associations between thinking styles and grit may protect against psychological pressure and rehabilitation problems and enable university/school administrators, counselors, social workers, teachers, parents, and students to enhance the grit of students who are deaf or hard of hearing.

Family-Centered Early Intervention Deaf/Hard of Hearing (FCEI-DHH): Call to Action.

This Call to Action is the eighth and final article in this special issue on Family-Centered Early Intervention (FCEI) for children who are deaf or hard of hearing (DHH) and their families, or FCEI-DHH. Collectively, these articles highlight evidence-informed actions to enhance family well-being and to optimize developmental outcomes among children who are DHH. This Call to Action outlines actionable steps to advance FCEI-DHH supports provided to children who are DHH and their families. It also urges specific actions to strengthen FCEI-DHH programs/services and systems across the globe, whether newly emerging or long-established. Internationally, supports for children who are DHH are often siloed, provided within various independent sectors such as health/medicine, education, early childhood, and social and disability services. With this Call to Action, we urge invested parties from across relevant sectors to join together to implement and improve FCEI-DHH programs/services and systems, build the capacity of early intervention (EI) Providers and other professionals, extend research regarding FCEI-DHH, and fund EI supports, systems, and research, all with the aim of advancing outcomes for families and their children who are DHH.

This article is the sixth in a series of eight articles that comprise a special issue on Family-Centered Early Intervention (FCEI) for children who are deaf or hard of hearing (DHH) and their families, or FCEI-DHH. The Support Principles article is the second of three articles that describe the 10 Principles of FCEI-DHH, preceded by the Foundation Principles, and followed by the Structure Principles, all in this special issue. The Support Principles are composed of four Principles (Principles 3, 4, 5, and 6) that highlight (a) the importance of a variety of supports for families raising children who are DHH; (b) the need to attend to and ensure the well-being of all children who are DHH; (c) the necessity of building the language and communication abilities of children who are DHH and their family members; and (d) the importance of considering the family's strengths, needs, and values in decision-making.

Family-Centered Early Intervention Deaf/Hard of Hearing (FCEI-DHH): Foundation Principles.

This article is the fifth in a series of eight articles that comprise a special issue on Family-Centered Early Intervention (FCEI) for children who are deaf or hard of hearing (DHH) and their families, or FCEI-DHH. The 10 FCEI-DHH Principles are organized conceptually into three sections (a) Foundation Principles, (b) Support Principles, and (c) Structure Principles. Collectively, they describe the essential Principles that guide FCEI for children who are DHH and their families. This article describes the Foundation Principles (Principles 1 and Principle 2). The Foundation Principles emphasize the essential elements of ensuring that families with children who are DHH can access early intervention (EI) and other appropriate supports, as well as highlight the need for provision of EI that is family-centered. Implementation of these FCEI-DHH Principles is intended to improve the lives and the outcomes of children who are DHH and their families around the globe.

Family-Centered Early Intervention Deaf/Hard of Hearing (FCEI-DHH): Guiding Values.

This article is the second of eight articles in this special issue on Family-Centered Early Intervention (FCEI) for children who are deaf or hard of hearing (DHH) and their families, or FCEI-DHH. Five foundational values that guide FCEI-DHH are described, providing an evidence-informed, conceptual context for the 10 FCEI-DHH Principles and other articles presented in this issue. These values are applicable for Early Intervention (EI) Providers and other professionals on FCEI teams, as well as for FCEI-DHH programs/services and systems. The five key values include (1) being family-centered, (2) responding to diversity, (3) involving invested parties, especially families and individuals who are DHH, (4) supporting holistic child development, and (5) ensuring fundamental human rights. These evidence-informed values are considered essential to the effective provision of FCEI-DHH supports.

Family-Centered Early Intervention Deaf/Hard of Hearing (FCEI-DHH): Introduction.

This article is the first of eight articles in this special issue on Family-Centered Early Intervention (FCEI) for children who are deaf or hard of hearing (DHH), or FCEI-DHH. In 2013, a diverse panel of experts published an international consensus statement on evidence-based Principles guiding FCEI-DHH. Those original Principles have been revised through a coproduction process involving multidisciplinary collaborators and an international consensus panel, utilizing the best available evidence and current understanding of how to optimally support children who are DHH and their families. This revision (referred to as expanded Principles) was motivated by the need to incorporate (a) input from family leaders and DHH leaders, (b) broader international and cultural perspectives, (c) new empirical evidence, and (d) research in human development. This Introduction provides an overview of the rationale, purposes, and main content areas to be addressed throughout the special issue.

Family-Centered Early Intervention Deaf/Hard of Hearing (FCEI-DHH): Methods.

This is the fourth article in a series of eight that comprise a special issue on family-centered early intervention (FCEI) for children who are deaf or hard of hearing (DHH) and their families, FCEI-DHH. This article describes the co-production team and the consensus review method used to direct the creation of the 10 Principles described in this special issue. Co-production is increasingly being used to produce evidence that is useful, usable, and used. A draft set of 10 Principles for FCEI-DHH and associated Tables of recommended behaviors were developed using the knowledge creation process. Principles were refined through two rounds of eDelphi review. Results for each round were analyzed using measures of overall group agreement and measures that indicated the extent to which the group members agreed with each other. After Round 2, with strong agreement and low to moderate variation in extent of agreement, consensus was obtained for the 10 Principles for FCEI-DHH presented in this special issue. This work can be used to enhance evolution of FCEI-DHH program/services and systems world-wide and adds to knowledge in improvement science.

Augmentative and alternative communication and deaf children with disabilities

ABSTRACT With recent data reporting approximately 40–50% of Deaf or hard of hearing (DHH) individuals as having a diability, complex communication needs are not uncommon within this population and can present unique communicative challenges. Implementing augmentative and alternative communication (AAC) systems can provide this population with an effective means of communication, assist them in developing specific language skills, and support them in effectively accessing their social environment. The purpose of this scoping review was to (a) identify the facilitators and barriers to AAC provision for this group of individuals, (b) discuss observable trends throughout studies, and (c) highlight areas for further research in AAC for this group of learners. This review compiles the results from seven studies within the last 10 years and focuses on the facilitators and barriers when implementing AAC systems for DHH individuals with a disability (DWD) and complex communication needs. The facilitators and barriers are categorised as interpersonal, intervention and assessment related. The trends that were identified included (a) the overall success of AAC, (b) the prevalence of speech-generating devices (SGD) use, (c) the lack of communication within interdisciplinary teams, (d) the lack of DHH-specific research, and (e) the lack of standardised methods for AAC selection.
