Inferencing Abilities of Deaf College Students: Foundations and Implications for Metaphor Comprehension and Theory of Mind
Understanding nonliteral language requires inferencing ability and is an important but complex aspect of social interaction, involving cognitive (e.g., theory of mind, executive function) as well as language skill, areas in which many deaf individuals struggle. This study examined comprehension of metaphor and sarcasm, assessing the contributions of hearing status, inferencing ability, executive function (verbal short-term/working memory capacity), and deaf individuals’ communication skills (spoken versus signed language, cochlear implant use). Deaf and hearing college students completed a multiple-choice metaphor comprehension task and inferencing tasks that included both social-emotional (i.e., theory of mind) and neutral inferences, as well as short-term memory span and working memory tasks. Results indicated the hearing students to have better comprehension of nonliteral language and the ability to make social-emotional inferences, as well as greater memory capacity. Deaf students evidenced strong relationships among inferential comprehension, communication skills, and memory capacity, with substantial proportions of the variance in understanding of metaphor and sarcasm accounted for by these variables. The results of this study enhance understanding of the language and cognitive skills underlying figurative language comprehension and theory of mind and have implications for the social functioning of deaf individuals.

Effects of Age at Cochlear Implantation on Vocabulary and Grammar: A Review of the Evidence
Purpose The increasing prevalence of pediatric cochlear implantation over the past 25 years has left little doubt that resulting improvements in hearing offer significant benefits to language development for many deaf children. Furthermore, given the documented importance of access to language from birth, there has been strong support for providing congenitally deaf children with implants as early as possible. Earliest implantation, in many ways, has become the \"gold standard\" in pediatric cochlear implantation, on the assumption that it is the key to language development similar to that of hearing children. Empirical evidence to support this assumption, however, appears more equivocal than generally is believed. This article reviews recent research aimed at assessing the impact of age at implantation on vocabulary and grammatical development among young implant users. Method Articles published between 2003 and 2018 that included age at implantation as a variable of interest and in which it was subjected to statistical analysis were considered. Effect sizes were calculated whenever possible; we conducted a multivariate meta-analysis to compare outcomes in different language domains. Results Taken together, findings from 49 studies suggest that age at implantation is just one of a host of variables that influence vocabulary and grammatical development, its impact varying with several factors including whether age at implantation is treated as a dichotomous or continuous variable. Results from a meta-analysis showed significant differences across language domains. Conclusion The pattern of results obtained indicates the importance of considering various child, family, and environmental characteristics in future research aimed at determining how early \"early implantation\" needs to be and the extent to which age at implantation, duration of implant use, and other factors influence language and language-related outcomes.

Finding Friends Online: Online Activities by Deaf Students and Their Well-Being
Generally, deaf and hard of hearing (D/HH) children have fewer friends than hearing peers and their friendships are of a lower quality. The research hypothesis was that using the computer to communicate with new online friends through social network sites or playing games with offline friends is associated with D/HH friendship qualities, because it removes certain communication barriers D/HH face in offline communication settings. With online questionnaires the relation between computer use and online, mixed (offline friend who you also speak in online settings), and offline friendship quality of D/HH and hearing students (18-25 years) was compared in both the Netherlands (n = 100) and the United States (n = 122). In addition, the study examined whether the different friendship qualities were related to the participants' well-being. Results showed that, in general, D/HH students' friendship qualities and levels of well-being were similar to their hearing peers. The quality of the mixed friendships was positively related to well-being. Furthermore, the frequency of pc use with both online and offline friends was positively related to friendships qualities in both hearing and D/HH students. A combination of the online and offline friendship seems to be the most important friendship type for both hearing and D/HH students and it is worthwhile to encourage this friendship type.

Deaf education beyond the western world : context, challenges, and prospects
\" If teachers want to educate deaf learners effectively, they have to apply evidence-informed methods and didactics with the needs of individual deaf students in mind. Education in general -- and education for deaf learners in particular -- is situated in broader societal contexts, where what works within the Western world may be quite different from what works beyond the Western world. By exploring practice-based and research-based evidence about deaf education in countries that largely have been left out of the international discussion thus far, this volume encourages more researchers in more countries to continue investigating the learning environment of deaf learners, based on the premise of leaving no one behind. Featuring chapters centering on 19 countries, from Africa, Asia, Latin America, and Central and Eastern Europe, the volume offers a picture of deaf education from the perspectives of local scholars and teachers who demonstrate best practices and challenges within their respective regional contexts. This volume addresses the notion of learning through the exchange of knowledge; outlines the commonalities and differences between practices and policies in educating deaf and hard-of-hearing learners; and looks ahead to the prospects for the future development of deaf education research in the context of recently adopted international legal frameworks. Stimulating academic exchange regionally and globally among scholars and teachers who are fascinated by and invested in deaf education, this volume strengthens the foundation for further improvement of education for deaf children all around the world. \"-- Provided by publisher.

Are Deaf Students’ Reading Challenges Really About Reading?
READING ACHIEVEMENT among deaf students typically lags significantly behind hearing peers, a situation that has changed little despite decades of research. This lack of progress and recent findings indicating that deaf students face many of the same challenges in comprehending sign language as they do in comprehending text suggest that difficulties frequently observed in their learning from text may involve more than just reading. Two experiments examined college students’ learning of material from science texts. Passages were presented to deaf (signing) students in print or American Sign Language and to hearing students in print or auditorially. Several measures of learning indicated that the deaf students learned as much or more from print as they did from sign language, but less than hearing students in both cases. These and other results suggest that challenges to deaf students’ reading comprehension may be more complex than is generally assumed.

Co-enrollment in deaf education
\"Co-enrollment programming in deaf education refers to classrooms in which a critical mass of deaf and hard-of-hearing (DHH) students is included in a classroom containing mainly hearing students and which is taught by both a mainstream teacher and a teacher of the deaf. It thus offers full access to both DHH and hearing students in the classroom through \"co-teaching\" and avoids both academic segregation of DHH students and their integration into classes with hearing students without appropriate support services or modification of instructional methods and materials. Co-enrollment thus seeks to give DHH learners the best of both (mainstream and separate) educational worlds. Co-enrollment programming has been described as a \"bright light on the educational horizon\" for DHH learners, giving them unique educational opportunities and educational access comparable to that of hearing peers. Co-enrollment programming shows great promise, but research concerning co-enrollment programming for DHH learners is still in its infancy. This volume provides descriptions of 14 co-enrollment programs from around the world, explaining their origins, functioning, and available outcomes. Set in the larger context of what we know and what we don't know about educating DHH learners, the volume offers readers a vision of a brighter future in deaf education for DHH children, their parents, and their communities\"-- Provided by publisher.

Are French Fries a Vegetable? Lexical Typicality Judgement Differences in Deaf and Hearing Learners
Deaf and hard-of-hearing (DHH) learners are known to have vocabulary knowledge and language outcomes more heterogeneous than their hearing peers, with a greater incidence of difficulties presumably related (both as cause and effect) to documented challenges in academic domains. In particular, there is increasing evidence that differences may exist in the ways that semantic networks are structured and accessed in DHH and hearing learners. Individuals’ judgments of word typicality offers a window into their semantic networks, revealing internal relationships in the mental lexicon. In the present study, 90 DHH and hearing college-aged learners provided typicality ratings at two points in time for 120 words common words considered to be central, borderline, or non-members of six categories. DHH and hearing participants differed in terms of their word knowledge, rating consistency, and rating magnitudes. Relative to hearing peers, DHH participants reported not knowing more of the words, but rated all words as being more typical than did hearing participants and rated the typicality of items more consistently over time. Implications of these findings for understanding mental lexicon structure for DHH and hearing learners, interpreting previous research, and constructing stimuli for future research are discussed.
