Beginning with an introduction to teaching and learning of both deaf and hearing students, Knoors and Marschark take an ecological approach to deaf education, emphasizing the need to take into account characteristics of learners and of the educational context. Building on the evidence base with respect to developmental and psychological factors in teaching and learning, they describe characteristics of deaf learners which indicate that teaching deaf learners is not, or should not, be the same as teaching hearing learners. In this volume, Knoors and Marschark explore factors that influence the teaching of deaf learners, including their language proficiencies, literacy and numeracy skills, cognitive abilities, and social-emotional factors. These issues are addressed in separate chapters, with a focus on the importance to all of them of communication and language. Separate chapters are devoted to the promise of multimedia enhanced education and the possible influences of contextual aspects of the classroom and the school on learning by deaf students. The book concludes by pointing out the importance of appropriate education of teachers of deaf learners, given the increasing diversity of those students and the contexts in which they are educated. It bridges the gap between research and practice in teaching and outlines ways to improve teacher education.

This article looked at the differences in type, frequency, and duration of stereotyped behaviours between individuals with and without ASD in this population. The study included 59 individuals with intellectual disabilities and sensory impairments. The presence of ASD was assessed using Observation of Autism in people with Sensory and Intellectual Disabilities (OASID). Separate from these assessments, video recordings were scored by observers naive to the ASD status of participants for stereotyped and repetitive behaviours. Stereotyped and repetitive behaviours were more prevalent in participants with ASD, though a large proportion of participants without ASD showed them too. Participants with ASD showed, on average, more frequent and in duration longer stereotyped and repetitive behaviours, especially self-inj...

Method Nine- to 11-year-old children with DLD ( n = 40) and TD children ( n = 26) participated in a word learning experiment. Half of the spoken pseudowords were taught with a pseudosign with learning outcomes being assessed in accuracy and speed. To investigate whether sign effects would hold for children with varying linguistic and cognitive abilities, we measured children's linguistic (vocabulary, syntax) and cognitive (divided attention, working memory [WM], lexical access) skills. Results The children with DLD showed a positive sign effect in both accuracy and speed. For the TD children, there was no effect of signs on word learning. Principal component analyses of the linguistic and cognitive m...

Further, it explored to what extent language at ages 7–8 years could be predicted by measures of language and/or WM at ages 4–5 years. Method Thirty children with SLI and 33 TD children who were previously examined on measures of WM and language at ages 4–5 years (T1) were reexamined at ages 7–8 years (T2). Results The developmental course of WM was mostly similar for the two groups; only the development of the verbal storage component differed. At T1, children with SLI performed significantly below their TD peers on all components of WM (verbal storage, verbal central executive [CE], visuospatial storage, and visuospatial CE), whereas at T2, the differences for the visuospatial components were no longer significant when age and intelligence were taken into account. Hierarchical regression show...

The results showed that, in general, the children mastered such tactile tasks, but some items posed special problems.

We measured N400 responses to semantically congruent and incongruent spoken sentences (e.g., "My father is eating an apple/*blanket") in a group of 37 Dutch preschoolers with SLI and in a group of 25 typically developing (TD) peers. We compared the time course and amplitude of the N400 effect between the two groups. The TD group showed a strong posterior N400 effect in time windows 300-500 ms and 500-800 ms. In contrast, the SLI group demonstrated only a reliable N400 effect in the later time window, 500-800 ms, and did not show a stronger presence at posterior electrodes. The findings suggest that the neuronal processing of semantic information at sentence level is atypical in preschoolers with SLI compared with...

In the present study, we examined the extent of delay in lexical and morphosyntactic spoken language levels of children with CIs as compared to those of a normative sample of age-matched children with normal hearing. Furthermore, the predictive value of auditory and verbal memory factors in the spoken language performance of implanted children was analyzed. Thirty-nine profoundly deaf children with CIs were assessed using a test battery including measures of lexical, grammatical, auditory and verbal memory tests. Furthermore, child-related demographic characteristics were taken into account. The majority of the children with CIs did not reach age-equivalent lexical and morphosyntactic language skills. Multiple linear regression analyses revealed that lexical spoken language performance in children ...

To our knowledge, it is the first study on hypertext comprehension in D/HH students and students with SLI, and it also considers the role of working memory. We compared hypertext versus linear text comprehension in D/HH students and students with SLI versus younger students without language problems who had a similar level of decoding and vocabulary. The results demonstrated no difference in text comprehension between the hierarchically structured hypertext and the linear text. Text comprehension of D/HH students and students with SLI was comparable to that of the students without language problems. In addition, there was a similar positive predictive value of visuospatial and not verbal working memory on hypertext comprehension for all three groups. The findings implicate that educational settings can make use of hierarchically structured hy...

Despite the fact that augmentative signs may aid second language learning in populations with a typical language development, empirical evidence in favor of this claim is lacking. We aim to investigate whether augmentative signs facilitate word learning for DHH children, children with SLI, and typically developing (TD) children. Whereas previous studies taught children new labels for familiar objects, the present study taught new labels for new objects. In our word learning experiment children were presented with pictures of imaginary creatures and pseudo words. Half of the words were accompanied by an augmentative pseudo sign. The children were tested for their receptive word knowledge. The DHH children benefitted significantly from augmentative signs, but the children with SLI and TD age-matched peers did not score significantly different on words from either the sign or no-sign condition. These results suggest that using Sign-Supported speech in classrooms of bimodal bilingual DHH children may support their spoken language development. The difference between earlier research findings and the present results may be caused by a difference in methodology.

The volume examines each issue with regard to language acquisition, language functioning, social-emotional functioning, and academic outcomes. It considers bilingualism and bilingual deaf education within the contexts of mainstream education of deaf and hard-of-hearing students in regular schools, placement in special schools and programs for the deaf, and co-enrollment programs, which are designed to give deaf students the best of both educational worlds. The volume offers both literature reviews and new findings across disciplines from neuropsychology to child development and from linguistics to cognitive psychology. With a focus on evidence-based practice, contributors consider recent investigations into bilingualism and bilingual programming in different educational contexts and in different countries that may have different models of using spoken and signed languages as well as different cultural expectations. The 18 chapters establish shared understandings of what are meant by "bilingualism," "bilingual education," and "co-enrollment programming," examine their foundations and outcomes, and chart directions for future research in this multidisciplinary area. Chapters are divided into three sections: Linguistic, Cognitive, and Social Foundations; Education and Bilingual Education; and Co-Enrollment Settings. Chapters in each section pay particular attention to causal and outcome factors related to the acquisition and use of these two languages by deaf learners of different ages. The impact of bilingualism and bilingual deaf education in these domains is considered through quantitative and qualitative investigations, bringing into focus not only common educational, psychological, and linguistic variables, but also expectations and reactions of the stakeholders in bilingual programming: parents, teachers, schools, and the deaf and hearing students themselves.

Hundreds of research and intervention studies have been aimed at improving the situation, but they have resulted in only limited progress. This paper examines cognitive functioning among deaf learners, describing and integrating research that indicates them to differ significantly from hearing learners in ways likely to affect learning. Findings demonstrating that deaf and hearing children differ in domains such as visual-spatial processing, memory, and executive functioning provide directions for both future research and practice. First, however, teachers and other professionals need to recognize that deaf children are not simply hearing children who cannot hear. Only then can teaching methods and materials fully accommodate their strengths and needs.

First, because they do not account for equifinality, the possibility that different conditions may lead to the same outcome. Second, because they do not have appropriate norms for this target population. The current study reviewed 20 instruments commonly used in the assessment of screening for and diagnosing ASD. Reviewed were: purpose, number of items, psychometric properties (norms, reliability, and validity), test availability, and item applicability for people with sensory and intellectual disabilities. Most instruments did not have norms for the target population and all instruments consisted of a quarter or more of invalid items. When using current instruments, caution is required in interpreting test results. For proper assessment of ASD in people with sensory and intellectual disabilities, more instruments are needed that are adapted to the sensory and intellectual disabilities of this population.

However, degraded or filtered auditory input as evidenced in children with cochlear implants (CIs) may result in less efficient or slower language processing as well. To provide insight into the underlying nature of the spoken language difficulties in children with CIs, linguistic profiles of children with CIs are compared with those of hard-of-hearing (HoH) children with conventional hearing aids and children with specific language impairment (SLI). To examine differences in linguistic abilities and profiles of children with CIs as compared with HoH children and children with SLI, and whether the spoken language difficulties of children with CIs mainly lie in limited auditory perception or in language processing problems.

In this review, a neuropsychological perspective on language impairments in SLI is taken, focusing specifically on executive functioning (EF) in preschoolers (age range: 2.6-6.1 years) with SLI. Based on the studies described in this review, it can be concluded that similar to school-aged children with SLI, preschoolers with SLI show difficulties in working memory, inhibition and shifting, as revealed by both performance based measures and behavioral ratings. It seems plausible that a complex, reciprocal relationship exists between language and EF throughout development. Future research is needed to examine if, and if yes how, language and EF interact in SLI. Broad neuropsychological assessment in which both language and EF are taken into account may contribute to early detection of SLI. This in turn can lead to early and tailored treatment of children with (suspected) SLI aimed not onl...
