Typical and atypical sign language learners
Abstract
Instructors of foreign languages in secondary and higher education often encounter diversity in learning abilities among their learners. Setting aside motivation and other academic factors, what makes one learner better at L1 or L2/Ln learning over another? Might some learners have a stronger aptitude for a signed language over a spoken language? And, how do we know how an atypical L1 or L2/Ln learner will fare in the classroom? These are interesting issues for the L1 and L2/Ln instructors as they consider adapting their instruction or activities for the range of skills and capacities within their class.
In this chapter, we focus on adolescent and adult learners of signed language, exploring situations of learner diversity or atypicality and how those differences impact signed language learning in both the L1 and L2/Ln contexts...
Language is the means of human access to the world. Languages have the virtue of opening up alternative ways of thinking and understanding the place people inhabit, relating to it, expanding it and modifying it. As a possibility of communication, languages open up opportunities to relate to other people, to get closer to them and to develop a broader understanding of the social and the human elements [1]. This research presents a visual tool designed to allow the learning of multiple words that are part of Spanish Sign Language (SSL) through an anthropomorphic model that is completely manipulable and programmable.
The present study aimed to identify predictors of one aspect of sign language acquisition, sign learning, in hearing nonsigners. Candidate predictors were selected based on the theory that the observed relationship between phonological short-term memory and L2 lexical learning is due in part to common perceptual-motor processes. Hearing nonsigning adults completed a sign learning task, three assessments of short-term memory for movements (movement STM; two of which used sign-like stimuli), and two visuospatial STM tasks. The final sample included 103 adults, ranging between 18 and 33 years of age. All predictors were moderately to strongly correlated with the sign learning task and to each other. A series of regression analyses revealed that both movement and visuospatial STM uniquely contributed to the prediction of sign learning. These results suggest that perceptual-motor processes play a significant role in sign learning and raise questions about the role of phonological processing.
A recent project entitled CATALISE used the Delphi method to reach a consensus on terminology for unexplained language problems in children. 'Developmental language disorder' (DLD) was the term agreed by a panel of 57 experts. Here I reflect on points of difficulty that arose when attempting to reach a consensus, using qualitative information from comments made by panel members to illustrate the kinds of argument used. One issue of debate was the use of labels, in particular the term 'disorder', which was seen as having both pros and cons. The potential for labels to stigmatize or create low expectations was a particular concern. However, labels could also ensure language problems were not trivialized and could help avoid stigma by providing an explanation for behaviours that might otherwise meet with disapproval. Further debate surrounded issues of how best to identify cases of disorder. Although it was agreed there should be a focus on cases with a poor prognosis, it was recognized that our knowledge of factors related to prognosis was still incomplete. Furthermore, there was a tension between use of standardized tests, which allow for a relatively objective and reliable assessment of language, and more qualitative observations, which can capture functional aspects of communication that are not always picked up on formal assessment. Debate also surrounded the issue of the relationship between DLD and other conditions. Some favoured drawing a distinction between DLD and language disorders associated with other conditions, and others regarded such distinctions as unnecessary. We concluded that it was misleading to assume co-occurring conditions were causes of language disorder, but it was helpful to distinguish DLD from cases of language disorder associated with 'differentiating conditions' that had a known or likely biomedical origin, including brain injury, sensorineural hearing loss, genetic syndromes, intellectual disability and autism spectrum disorder. Furthermore, DLD could co-occur with milder neurodevelopmental disorders that did not have a clear biomedical aetiology. Normal-range non-verbal IQ has traditionally been incorporated in the diagnosis of DLD, but this was rejected as unsupported by evidence. DLD is a category that has utility in identifying children who would benefit from speech-language therapy services, but it should not be thought of as a well-defined condition. DLD has a multifactorial aetiology, is heterogeneous in terms of language features and overlaps with other neurodevelopmental disorders. Our notions of DLD are likely to be refined by further research into aetiology, associated characteristics and intervention effectiveness.
This paper discusses the process of undertaking an exploratory longitudinal study of language learning and interpreter aptitude. It discusses the context of aptitude testing, the test selection for a test battery, the recruitment of subjects within the small-scale study (n=22) and the administration of that battery within the context of whether longitudinal studies are feasible with small cohorts of sign language interpreters. Sign languages continue to be languages of limited diffusion in Europe. Even with gradually increasing numbers of 'hearing' sign language users, typically those wishing to become sign language interpreters do not have high levels of sign language fluency prior to enrolling in sign language interpreter training. As such, these students need to gain fluency in sign language, whilst also beginning to engage in interpreter education and interpreting-skills development. To date there is little understanding of how best to screen sign language interpreter program applicants to ensure the effective use of resources, i.e. to educate those who will both learn sign language to C1 fluency (Pro-signs, 2016) during the BA and also be able to learn how to interpret. Longitudinal studies enable us to take a longer view of learning and the professionalisation of skills and knowledge. They do, however, require significant time and this in itself can prove to be an obstacle when university researchers are required to produce tangible research outputs for career goals such as promotion or tenure.
Foreign language (FL) aptitude generally refers to a specific talent for learning a foreign or second language (L2). After experiencing a long period of marginalized interest, FL aptitude research in recent years has witnessed renewed enthusiasm across the disciplines of educational psychology, second language acquisition (SLA) and cognitive neuroscience. This paper sets out to offer a historical and an updated account of this recent progress in FL aptitude theory development and research. As its subtitle indicates, the paper centres on three major issues: following the introduction and clarification of basic concepts, Section 1 traces the early conceptions of FL aptitude dominated by John Carroll's pioneering work. Section 2 summarizes and examines more recent theoretical perspectives and FL aptitude models proposed by researchers from multiple disciplines that have significantly broadened the conventional research traditions associated with Carroll's original conception. Based on the research synthesis of current FL aptitude models, Section 3 suggests the directions FL aptitude theory and research might take in coming years. We conclude that a working memory perspective on FL aptitude presents one promising avenue for advance, as does the development of new aptitude tests to predict speed of automatization, implicit learning and greater control over an emerging language system. In addition, it is argued that issues of domain-specificity versus domain-generality for aptitude tests may lead to aptitude theory and research becoming more central in applied linguistics.
Working memory capacity and fluid intelligence have been demonstrated to be strongly correlated traits. Typically, high working memory capacity is believed to facilitate reasoning through accurate maintenance of relevant information. In this article, we present a proposal reframing this issue, such that tests of working memory capacity and fluid intelligence are seen as measuring complementary processes that facilitate complex cognition. Respectively, these are the ability to maintain access to critical information and the ability to disengage from or block outdated information. In the realm of problem solving, high working memory capacity allows a person to represent and maintain a problem accurately and stably, so that hypothesis testing can be conducted. However, as hypotheses are disproven or become untenable, disengaging from outdated problem solving attempts becomes important so that new hypotheses can be generated and tested. From this perspective, the strong correlation between working memory capacity and fluid intelligence is due not to one ability having a causal influence on the other but to separate attention-demanding mental functions that can be contrary to one another but are organized around top-down processing goals.
A meta-analysis was conducted to examine the construct validity of language aptitude by synthesizing the existing research that has been accumulated over the past five decades. The study aimed to provide a thorough understanding of the construct by aggregating the data reported in the primary research on its correlations with other individual difference variables and with second language (L2) achievement. A total of 66 studies were retrieved that contributed effect sizes based on 109 unique samples and 13,035 foreign language learners. The results revealed that (1) aptitude was independent of other cognitive and affective factors: it was distinct from motivation, had a negative correlation with anxiety, and overlapped with, but was distinguishable from, intelligence; (2) executive working memory was more strongly associated with aptitude and aptitude components than phonological short-term memory; (3) aptitude measured using full-length tests was a strong predictor of general L2 proficiency, but it had low predictive validity for vocabulary learning and L2 writing; and (4) different aptitude components demonstrated differential predictive validity for different aspects of learning. The findings are useful for tackling a number of conundrums surrounding language aptitude and shed light on how to reconceptualize the construct and reorient the research.
In the teaching of sign languages as foreign languages (FLs), teachers instruct learners in vocabulary and conversational grammar. In doing so they frequently notice that some learners are able to learn and produce vocabulary and use correct grammar, whereas others struggle. For a better understanding of learners' learning processes and their own pedagogical approaches, FL teachers turn to research studies on the teaching and learning of FLs. However, those studies are often largely inapplicable to their in-classroom practices. To resolve this problem, this article proposes and explicates teacher-as-researcher as a research paradigm for teachers' pedagogical development to bring about improved learner outcomes.
We report the first study on pronoun use by an under-studied research population, children with autism spectrum disorder (ASD) exposed to American Sign Language from birth by their deaf parents. Personal pronouns cause difficulties for hearing children with ASD, who sometimes reverse or avoid them. Unlike speech pronouns, sign pronouns are indexical points to self and other. Despite this transparency, we find evidence from an elicitation task and parental report that signing children with ASD avoid sign pronouns in favor of names. An analysis of spontaneous usage showed that all children demonstrated the ability to point, but only children with better-developed sign language produced pronouns. Differences in language abilities and self-representation may explain these phenomena in sign and speech.
Children with specific language impairment (SLI) perform poorly on sentence repetition tasks across different spoken languages, but until now, this methodology has not been investigated in children who have SLI in a signed language. Users of a natural sign language encode different sentence meanings through their choice of signs and by altering the sequence and inflections of these signs. Grammatical information is expressed through movement and configurational changes of the hands and face. The visual modality thus influences how grammatical morphology and syntax are instantiated. How would language impairment impact on the acquisition of these types of linguistic devices in child signers? We investigated sentence repetition skills in a group of 11 deaf children who display SLI in British Sign Language (BSL) and 11 deaf controls with no language impairment who were matched for age and years of BSL exposure. The SLI group was significantly less accurate on an overall accuracy score, and they repeated lexical items, overall sentence meaning, sign order, facial expressions, and verb morphological structures significantly less accurately than controls. This pattern of language deficits is consistent with the characterization of SLI in spoken languages even though expression is in a different modality. We conclude that explanations of SLI, and of poor sentence repetition by children with this disorder, must be able to account for both the spoken and signed modalities.
Parents of small deaf children need guidance on constructing home and school environments that affect normal language acquisition. They often turn to physicians and spiritual leaders and, increasingly, the internet. These sources can be underinformed about crucial issues, such as matters of brain plasticity connected to the risk of linguistic deprivation, and delay or disruption in the development of cognitive skills interwoven with linguistic ability. We have formed a team of specialists in education, linguistics, pediatric medicine, and psychology, and at times specialists in theology and in law have joined our group. We argue that deaf children should be taught a sign language in the early years. This does not preclude oral-aural training and assistive technology. With a strong first language (a sign language), the child can become bilingual (with the written form of the ambient spoken language and, perhaps, the spoken form), accruing the benefits of bilingualism. We have published in medical journals, addressing primary care physicians, in a journal with a spiritual-leader readership, and in a health-law journal. Articles in progress address medical educators and practitioners. Team members present findings at conferences, work on lobbying and legislative efforts with the National Association of the Deaf, and spread the word at conferences of target audiences. We share our work in Word format, so that anyone can easily appropriate it for our common interests. One of our articles has been downloaded over 27,000 times (as of April 2014), and we are asked to consult with committees in other countries as they draft national policies.
Facial expressions in sign language carry a variety of communicative features. While emotion can modulate a spoken utterance through changes in intonation, duration and intensity, in sign language specific facial expressions presented concurrently with a manual sign perform this function. When deaf adult signers cannot see facial features, their ability to judge emotion in a signed utterance is impaired (Reilly et al. in Sign Lang Stud 75:113-118, 1992). We examined the role of the face in the comprehension of emotion in sign language in a group of typically developing (TD) deaf children and in a group of deaf children with autism spectrum disorder (ASD). We replicated Reilly et al.'s (Sign Lang Stud 75:113-118, 1992) adult results in the TD deaf signing children, confirming the importance of the face in understanding emotion in sign language. The ASD group performed more poorly on the emotion recognition task than the TD children. The deaf children with ASD showed a deficit in emotion recognition during sign language processing analogous to the deficit in vocal emotion recognition that has been observed in hearing children with ASD.
Although working memory (WM) figures centrally in many theories of second language (L2) proficiency development and processing, some have argued that the importance of WM is overstated (e.g., Juffs, Transactions of the Philological Society, 102, 199-225, 2004). Despite many studies over the past two decades, the literature lacks a quantitative synthesis of the extant results. In this article, we report a meta-analysis of data from 79 samples involving 3,707 participants providing 748 effect sizes. The results indicate that WM is positively associated with both L2 processing and proficiency outcomes, with an estimated population effect size (ρ) of .255. In additional analyses, we assessed whether the WM-criterion relationship was modulated by potential covariates identified in the literature search (i.e., participant characteristics, WM measure features, criterion measure factors, and publication status). The results of the covariate analyses indicated larger effect sizes for the executive control (vs. storage) component of WM, and for verbal (vs. nonverbal) measures of WM. Minimal publication bias was detected, suggesting that WM has a robust, positive relationship with L2 outcomes. We discuss the implications of these results for models of WM and theories of L2 processing and L2 proficiency development.
Various theories of developmental language impairments have sought to explain these impairments in modality-specific ways – for example, that the language deficits in SLI or Down syndrome arise from impairments in auditory processing. Studies of signers with language impairments, especially those who are bilingual in a spoken language as well as a sign language, provide a unique opportunity to contrast abilities across language in two modalities (cross-modal bilingualism). The aim of the article is to examine what developmental sign language impairments can tell us about the relationship between language impairments and modality. A series of individual and small group studies are presented here illustrating language impairments in sign language users and cross-modal bilinguals, comprising Landau-Kleffner syndrome, Williams syndrome, Down syndrome, Autism and SLI. We conclude by suggesting how studies of sign language impairments can assist researchers to explore how different language impairments originate from different parts of the cognitive, linguistic and perceptual systems.
The last 2 decades witnessed a growth in American Sign Language (ASL) as a foreign language in U.S. secondary schools. This overview of the current state of ASL as a foreign language in the schools consists of a history and a survey. The information on history was drawn from a study conducted by Rosen (2006). This history is followed by a national survey compiled by Rosen (2005) on U.S. secondary schools offering ASL for foreign language credit. The survey provided information on the number and distribution of schools, teachers, classes, students, departments, and the process for program implementation. The information is used to ascertain the current breadth and scope of, and to discern trends in, ASL as a foreign language in public high schools nationwide.
There is controversy over the specificity of Specific Language Impairment (SLI), and whether it is caused by a deficit general to cognition or in mechanisms specific to language itself. We argue that evidence to resolve these conflicting positions could come from the study of children who are acquiring sign language and have SLI. Whereas speech is characterized by rapid temporal changes, the phonology of sign languages relies on the integration of visual information that is often produced simultaneously. These differences in the way linguistic information is processed can allow us to investigate whether SLI is caused by a sensory processing deficit, by a deficit specific to language, or by a deficit in phonological short term memory. One marker for SLI in spoken languages is difficulty repeating non-words, particularly those with complex phonological structures. We report on the development of a non-sign repetition task for BSL users, piloted on deaf children, which is sensitive to age. Non-sign items were graded in terms of phonological complexity, and reveal systematic error patterns as a function of that complexity. We conclude by discussing how this test can be used to probe the underlying nature of language impairments.
This article reviews and discusses existing sign language assessment instruments and those that are still under development. There are three groupings of sign language assessments: (1) instruments to assess and monitor the process of sign language acquisition in deaf children, (2) assessments for educational purposes, and (3) instruments for linguistic research. These will be discussed individually with regard to a range of issues, such as target age group, linguistic content of the assessment instrument, background of the instrument and development, usability and availability, and strengths and weaknesses. The article concludes with an evaluation of the reviewed instruments.
This article describes the case of a deaf native signer of American Sign Language (ASL) with a specific language impairment (SLI). School records documented normal cognitive development but atypical language development. Data include school records; interviews with the child, his mother, and school professionals; ASL and English evaluations; and a comprehensive neuropsychological and psychoeducational evaluation, and they span an approximate period of 7.5 years (11;10-19;6) including scores from school records (11;10-16;5) and a 3.5-year period (15;10-19;6) during which we collected linguistic and neuropsychological data. Results revealed that this student has average intelligence, intact visual perceptual skills, visuospatial skills, and motor skills but demonstrates challenges with some memory and sequential processing tasks. Scores from ASL testing signaled language impairment and marked difficulty with fingerspelling. The student also had significant deficits in English vocabulary, spelling, reading comprehension, reading fluency, and writing. Accepted SLI diagnostic criteria exclude deaf individuals from an SLI diagnosis, but the authors propose modified criteria in this work. The results of this study have practical implications for professionals including school psychologists, speech language pathologists, and ASL specialists. The results also support the theoretical argument that SLI can be evident regardless of the modality in which it is communicated.
This study is an examination of the relationship between phonological short-term memory, or simply phonological memory (PM), language learning aptitude, and second language (L2) proficiency in advanced adult L2 learners (French native speakers, N = 40) with relatively homogeneous previous and current L2 experience. PM was measured by two different measures: a nonword repetition (NWR) task and a serial recognition (SR) task. Correlational analyses revealed that PM, as measured by each of the tasks, was significantly related to L2 proficiency. Aptitude (measured by the TALV, Test d'aptitude aux langues vivantes) also correlated significantly with L2 proficiency and with PM (NWR). The two PM tasks were significantly correlated. An exploratory factor analysis revealed three main factors: memory, L2 proficiency (reading and vocabulary) and aptitude (Spelling Clues and Words in Sentences). Overall, results reveal continuing links between phonological memory, aptitude, and L2 proficiency in advanced learners.
Conventional wisdom in education has suggested that students who are classified as learning disabled (LD) will exhibit inordinate difficulties learning a foreign language (FL). Even when not explicitly stated, the notion that those classified as LD have a disability for FL learning is implied. However, while beliefs about this purported disability have been supported by anecdotes, personal opinions, and case studies, the beliefs themselves have not been supported by empirical evidence. Advocates of a disability for FL learning have ignored the empirical evidence, which substantiates that there is, in fact, not a special relationship between FL learning and LDs, nor is there a unique disability for FL learning. This article cites several myths about LDs and FLs and examines the evidence that falsifies each of the myths. © 2016 by American Council on the Teaching of Foreign Languages
Two populations have been found to exhibit delays in theory of mind (ToM): deaf children of hearing parents and children with autism spectrum disorder (ASD). Deaf children exposed to sign from birth by their deaf parents, however, show no such delay, suggesting that early language exposure is key to ToM development. Sign languages also present frequent opportunities with visual perspective-taking (VPT), leading to the question of whether sign exposure could benefit children with ASD. We present the first study of children with ASD exposed to sign from birth by their deaf parents. Seventeen native-signing children with a confirmed ASD diagnosis and a chronological- and mental age-matched control group of 18 typically developing (TD) native-signing deaf children were tested on American Sign Language (ASL) comprehension, two minimally verbal social cognition tasks (ToM and VPT), and one spatial cognition task (mental rotation). The TD children outperformed the children with ASD on ASL comprehension (p < 0.0001), ToM (p = 0.02), and VPT (p < 0.01), but not mental rotation (p = 0.12). Language strongly correlated with ToM (p < 0.01) and VPT (p < 0.001), but not mental rotation (p = ns). Native exposure to sign is thus insufficient to overcome the language and social impairments implicated in ASD. Contrary to the hypothesis that sign could provide a scaffold for ToM skills, we find that signing children with ASD are unable to access language so as to gain any potential benefit sign might confer. Our results support a strong link between the development of social cognition and language, regardless of modality, for TD and ASD children.

Reflecting the exponential growth of college courses offering American Sign Language (ASL) as a foreign language, high schools have followed suit with significant increases in ASL classes during the past two decades. Despite this trend, high school ASL teachers and program administrators possess no concrete information on why students take ASL for foreign language credit, how they learn new signs and grammar, and how different learning techniques determines their achievement in ASL. This new book addresses these issues to better prepare high schools in their recruitment and education of new ASL students. Author Russell S. Rosen begins with the history of ASL as a foreign language in high schools, including debates about the foreign language status of ASL, the situation of deaf and hard of hearing students in classes, and governmental recognition of ASL as a language. Based on his study of five high school ASL programs, he defines the factors that motivate students, including community and culture, and analyzes strategies for promoting language processing and learning. Learning American Sign Language in High School provides strategies for teaching ASL as a second language to students with learning disabilities as well. Its thorough approach ensures the best opportunity for high school students high levels of achievement in learning ASL.
It has become fashionable to equate constructs of working memory (WM) and general intelligence (g). Few investigations have provided direct evidence that WM and g measures yield similar ordering of individuals. Correlational investigations have yielded mixed results. The authors assess the construct space for WM and g and demonstrate that WM shares substantial variance with perceptual speed (PS) constructs. Thirty-six ability tests representing verbal, numerical, spatial, and PS abilities; the Raven Advanced Progressive Matrices; and 7 WM tests were administered to 135 adults. A nomological representation for WM is provided through a series of cognitive and PS ability models. Construct overlap between PS and WM is further investigated with attention to complexity, processing differences, and practice effects.
LEARNERS WITH MULTIPLE DISABILITIES present such significant challenges to educators that-at first glance-the prospect of designing curriculum for them could appear overwhelming. The task need not be daunting, however. Knowledge in four broad areas can guide the development of valid, cohesive, and effective curricula for students with multiple disabilities: • a positive understanding of the challenges involved, • valid assumptions about the students' abilities and instructional variables, • inclusive approaches to curriculum design, and • the scope and sequence of relevant curricular areas.
Previous studies show that verbal short-term memory (VSTM) is related to vocabulary learning, whereas verbal working memory (VWM) is related to grammar learning in children learning a second language (L2) in the classroom. In this study, we investigated whether the same relationships apply to children learning an L2 in a naturalistic setting and to monolingual children. We also investigated whether relationships with verbal memory differ depending on the type of grammar skill investigated (i.e., morphology vs. syntax). Participants were 63 Turkish children who learned Dutch as an L2 and 45 Dutch monolingual children (mean age=5years). Children completed a series of VSTM and VWM tasks, a Dutch vocabulary task, and a Dutch grammar task. A confirmatory factor analysis showed that VSTM and VWM represented two separate latent factors in both groups. Structural equation modeling showed that VSTM, treated as a latent factor, significantly predicted vocabulary and grammar. VWM, treated as a latent factor, predicted only grammar. Both memory factors were significantly related to the acquisition of morphology and syntax. There were no differences between the two groups. These results show that (a) VSTM and VWM are differentially associated with language learning and (b) the same memory mechanisms are employed for learning vocabulary and grammar in L1 children and in L2 children who learn their L2 naturalistically.

This examination of the literature on foreign, or second, language learning by native English–speaking students with disabilities addresses the benefits of language learning, the practices and policies of language exemption, the perceptions of students and educators regarding those practices, and available resources for supporting students with special needs. It aims to question the policy of granting foreign language exemptions while additionally providing insights for educators into the development of inclusive foreign language learning environments.
This chapter reviews published or known assessments of children's language proficiency across a number of the world's signed languages, including American Sign Language, British Sign Language, Australian Sign Language, Sign Language of the Netherlands, and German Sign Language. Critical issues in sign language assessment are also discussed, with special attention to possible threats to test reliability and validity. For example, test examiners may doubt the authenticity of the elicited language sample from a deaf, signing child, or test developers may question whether an adaptation of a spoken-language test is appropriate for use with deaf, signing children. The authors conclude that there remains a critical need in many countries for commercially available, and easy to administer, signed language proficiency assessments for use in research and education settings with deaf and hearing individuals.
This study analyzed phonological short-term memory (PSTM) and working memory (WM) and their relationship with vocabulary and grammar learning in an artificial foreign language. Nonword repetition, nonword recognition, and listening span were used as memory measures. Participants learned the singular forms of vocabulary for an artificial foreign language before being exposed to plural forms in sentence contexts. Participants were tested on their ability to induce the grammatical forms and to generalize the forms to novel utterances. Individual differences in final abilities in vocabulary and grammar correlated between 0.44 and 0.76, depending on the measure. Despite these strong associations, the results demonstrated significant independent effects of PSTM and WM on L2 vocabulary learning and on L2 grammar learning, some of which were mediated by vocabulary and some of which were direct effects.
In signed languages, the articulatory space in front of the signer is used grammatically, topographically, and to depict a real or imagined space around a signer and thus is an important consideration in signed language acquisition. It has been suggested that children who acquire signed languages rely on concomitant visual-spatial development to support their linguistic development. We consider the case of a native-signing deaf adolescent female with average intelligence who had been reported to struggle with spatial aspects of American Sign Language (ASL) as a child. Results of a battery of linguistic and nonlinguistic tests suggest that she has relatively good ASL skills with the exception of some specific difficulties on spatial tasks that require attention to ASL and nonlinguistic topographic space or changes in visual perspective (e.g., classifiers and referential shift). This child has some difficulties with visual-spatial abilities, and we suggest that this has affected her acquisition of those aspects of ASL that are heavily dependent on visual-spatial processing.
As increasing numbers of colleges and universities require a foreign language for graduation in at least one of their degree programs, reports of students with difficulties in learning a second language are multiplying. Until recently, little research has been conducted to identify the nature of this problem. Recent attempts by the authors have focused upon subtle but ongoing language difficulties in these individuals as the source of their struggle to learn a foreign language. The present paper attempts to expand upon this concept by outlining a theoretical framework based upon a linguistic coding model that hypothesizes deficits in the processing of phonological, syntactic, and/or semantic information. Traditional psychoeducational assessment batteries of standardized intelligence and achievement tests generally are not sensitive to these linguistic coding deficits unless closely analyzed or, more often, used in conjunction with a more comprehensive language assessment battery. Students who have been waived from a foreign language requirement and their proposed type(s) of linguistic coding deficits are profiled. Tentative conclusions about the nature of these foreign language learning deficits are presented along with specific suggestions for tests to be used in psychoeducational evaluations.
Many deaf children have multiple disabilities. In this chapter the concept '"multiple disabilities' disabilities" is explained. Subsequently etiology is discussed, followed by information about deafblindness, deafness and autism, and deafness and intellectual disabilities. Educational accommodations, including assessment, access to communication and language (including cochlear implantation), and curricula for deafblind children, are the subject of the remainder of this chapter.

We explore the predictors of early mastery versus error in children's acquisition of American Sign Language. We hypothesize that the most frequent values for a particular parameter in prelinguistic gesture will be the most frequent in early signs and the most likely sources of substitution when signing children make errors. Analyses of data from a longitudinal study of the prelinguistic gestures of five Deaf and five hearing children and a longitudinal study of four Deaf children's early signs have revealed evidence of significant commonalities between prelinguistic gesture and early sign. This apparent continuity between prelinguistic gesture and early sign reflects constraints operating on the infant - in all likelihood, motoric constraints - that seem to persist into the first-word period in both major language modalities. In sign, as in speech, the production of first signs uses building blocks that are available to the prelinguistic child.
Experimental second language acquisition research typically investigates the effectiveness of instruction in terms of overall group gains. A particular instructional method may not, however, benefit all learners uniformly. This study, conducted in a New Zealand secondary school, establishes whether there is any relationship between the effectiveness of three instructional methods, and learner aptitude. Students (n = 60) were assigned to one of three groups (deductive instruction group, inductive instruction group, structured input instruction group) and received instruction that targeted direct object pronouns in L2 French. All students were assessed on the following three measures of language aptitude: (a) language analytic ability, (b) phonemic coding ability and (c) working memory.
Results indicate that deductive instruction that gives students opportunities to produce language output may neutralize individual differences in language aptitude.
Performance on measures of working memory (WM) capacity predicts performance on a wide range of real-world cognitive tasks. I review the idea that WM capacity (a) is separable from short-term memory, (b) is an important component of general fluid intelligence, and (c) represents a domain-free limitation in ability to control attention. Studies show that individual differences in WM capacity are reflected in performance on antisaccade, Stroop, and dichotic-listening tasks. WM capacity, or executive attention, is most important under conditions in which interference leads to retrieval of response tendencies that conflict with the current task.
This article reviews current epidemiological studies estimating the prevalence and incidence of permanent hearing loss in children. In particular, it addresses trends in ages of onset of hearing loss and causes. Studies estimating the number of children with hearing loss and additional special needs in various countries are presented, as well as some of the well-known causes of hearing loss which have co-occurring associated disabilities. The case of linguistically diverse children is presented as a new group of children with hearing loss who may function with multiple disabilities.
After a review of the problem of predicting foreign language success, this booklet describes the development, refinement, and validation of a battery of psychological tests, some involving tape-recorded auditory stimuli, for predicting rate of progress in learning a foreign language. Although the battery was developed for more general application in high schools and colleges, this article focuses on the results obtained in a variety of "intensive" or semi-intensive foreign language courses in a variety of Western and non-Western languages, mainly under governmental auspices, as in the Air Force or at the Foreign Service Institute. Validity coefficients for the tests often reached high levels, with multiple correlations as high as .84. Results suggest there are at least four main components of foreign language aptitude: phonetic coding ability, grammatical sensitivity, rote memory for foreign language materials, and inductive language learning ability. Aptitude is general over different languages, and the tests offer diagnostic possibilities. Results are interpreted in terms of a model that depicts relations among aptitude, ability to understand instruction, motivation, time allowed for learning, and quality of instruction. An appendix of test descriptions and a list of references accompany the text. (Author)
Studies the developmental stages deaf children pass through in acquiring the adult forms of pronominal classifiers in American Sign Language. Data were obtained on production, comprehension, and imitation from nine children aged 3 to 11. Complexities of classifier usage influence the learning strategies used. (PJM)
Reviews the state of knowledge in 4 categories of individual differences in aptitude for learning—cognitive abilities, achievement motivation, vocational and academic interests, and creativity. Specific topics addressed include the taxonomy of intelligence, need for achievement, evaluation anxiety, and information-processing analyses. Ways are examined in which research on individual differences has led or can lead to improvements in various educational functions, including guidance counseling, student selection and advanced placement, design of adaptive instructional systems and teaching strategies, evaluation of educational practices, and the tracking of national human resources.

This report on 2 studies of factors involved in learning French is based on 23 tests administered to 208 students in college French, and on 22 tests administered to 202 additional students a year later. The factors extracted and rotated in each study included: Verbal, Reasoning, Speed of Articulation, Pitch Discrimination, Timbre Discrimination, Interest, and Biographic. Multiple correlation test selection analyses resulted in (a) R=.65, using 6 tests to predict Cooperative French Test scores; and (b) R=.41, using 5 tests to predict aural comprehension; and (c) R=.41, using 5 tests to predict speaking proficiency. Verbal IQ and Interest (motivation) appear to be the most important factors in college foreign language learning; Reasoning, Word Fluency, and Pitch Discrimination also contribute.

American Sign Language (ASL) has become a very popular language in high schools, colleges, and universities throughout the U.S., due, in part, to the growing number of schools that allow students to take the language in order to fulfill a foreign or general language requirement. Within the past couple decades, the number of students enrolled in ASL classes has increased dramatically, and there are likely more instructors of ASL at the present time than ever before. ASL and spoken language instruction are similar in some aspects; however, there are also differences between the two (e.g., modality differences involving visual rather than auditory perception and processing, no commonly used writing system in ASL, and the socio-cultural history of deaf-hearing relations). In spite of these differences, minimal research has been done on ASL learning and classroom pedagogy—especially in recent years. This article reports on studies that have been performed recently and it also suggests various themes for future research. In particular, three main areas of research are proposed: the possible role of the socio-political history of the Deaf community in which ASL teaching is situated, linguistic differences between signed and spoken languages, and the use of video and computer-based technologies.
An unusual facet of American Sign Language (ASL) is its use of grammaticized facial expression. In this study, we examine the acquisition of conditional sentences in ASL by 14 deaf children (ages 3;3–8;4) of deaf parents. Conditional sentences were chosen because they entail the use of both manual signs and grammaticized non-manual facial expressions. The results indicate that the children first acquire manual conditional signs, e.g., SUPPOSE, before they use the obligatory grammaticized conditional facial expression. Moreover, the children acquire the constellation of obligatory non-manual behaviors component by component, rather than holistically.
