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.

It is hypothesized that strategies and techniques employed by “expert” language learners differ from those of “novice” learners. In this study, the performance of multilingual subjects was contrasted to that of bilingual and monolingual subjects on two tasks that involved learning a miniature linguistic system. Under “implicit” learning conditions, multilingual subjects showed superior performance to that of the other two groups, but under “explicit” conditions, there were no differences. The results were interpreted in information processing terms as indicating that multilingual subjects have strategies that help them allocate processing resources more efficiently than our other subjects in formulating informal rules of limited scope under implicit conditions.

This study tested the hypothesis that factors that shape children’s production of their native language (L1) will also influence adults’ pronunciation of sounds in a foreign language (L2). The final stops in CVC English words produced by 12 adult native speakers each of English, Polish, Spanish, and Chinese were phonetically transcribed. The frequency with which these stops were devoiced, deleted, or fricativized was tabulated. The Spanish subjects (unlike the Chinese or Poles) showed the effect of a transfer process, producing word-final /b, d, g/as fricatives. Subjects in all three non-native groups (but not the native English subjects) resembled English-learning children in devoicing word-final /b, d, g/. Subjects whose L1 does not have word-final stops (i.e., the native speakers of Chinese and Spanish) showed another process commonly observed in English L1 acquisition: final stop deletion. A number of language background variables (e.g., age of arrival in the United States) were found not to be significantly correlated with the accuracy of final stop production. These findings suggest that, in addition to transfer processes arising from L1/L2 phonetic and phonological differences, developmental processes similar to those affecting child L1 speech production also influence adult L2 speech production.

The goal of the present investigation was to identify the reading processes that are impaired in children whose digit naming speeds are slow. Continuous digit naming speed was assumed to measure the automaticity with which character codes may be accessed in memory, and the automaticity of this process was assumed to be a prerequisite for the accurate performance of higher level reading processes. In Study I it was found, for children in grades 1 through 3, that digit naming speed was reliably correlated with reading of both irregularly spelled words and pronounceable nonsense words, and that most of the variance shared by irregular-word and nonsense-word reading was accounted for by digit naming speed. These results were interpreted as evidence that character-identification automaticity is equally important to the direct-access and speech-recoding routes of word recognition. Models of how character-identification automaticity might affect each of these routes are discussed. In Study 2 it was found, for children in grades 4 through 10, that the correlation of digit naming speed with reading comprehension was significantly smaller than its correlation with word recognition, and that the former correlation was completely accounted for when either WISC-R verbal IQ or word-recognition accuracy was controlled. These results are contrasted with comparable results reported by other investigators, and methodological differences are noted.

The study of bilingualism has a history that extends from deciphering ancient multilingual texts to mapping the structure of the multilingual brain. The language experiences of individual bilinguals are equally diverse and characterized by unique contexts of acquisition and use that can shape not only sociocultural identity but also cognitive and neural function. Perhaps unsurprisingly, this variability in scholarly perspectives and language experiences has given rise to a range of methods for defining bilingualism. The goal of this article is to initiate a conversation about the utility of a more unified approach to how we think about, study, and measure bilingualism. Using concrete case studies, we illustrate the value of enhancing communication and streamlining terminology across researchers with different methodologies within questions, different questions within domains, and different domains within scientific inquiry. We specifically consider the utility and feasibility of a bilingualism quotient (BQ) construct, discuss the idea of a BQ relative to the well-established intelligence quotient, and include recommendations for next steps. We conclude that though the variability in language backgrounds and approaches to defining bilingualism presents significant challenges, concerted efforts to systematize and synthesize research across the field may enable the construction of a valid and generalizable index of multilingual experience.

Second-language “Immersion” school programs that have been developed in Canada and the United States during the last two decades are described and the results of evaluative research pertaining to them are reviewed. Major Immersion program alternatives (i.e., Early, Delayed, and Late variants) along with their theoretical bases and pedagogical characteristics are described first. Research findings are then discussed with respect to the impact of participation in an Immersion program on the students' native-language development, academic achievement, second-language proficiency, and on their attitudes and second-language use. Also, the suitability of Immersion in different geographical/social settings and for students with distinctive, potentially handicapping characteristics is considered. It is concluded that second-language Immersion programs are feasible and effective forms of education for majority-language children with diverse characteristics.

Adult second-language (L2) learners’ perception of L2 phonetic segments is influenced by first-language phonological and phonetic properties. It was recently proposed that L2 vocabulary size in adult learners is related to changes in L2 perception (perceptual assimilation model), analogous to the emergence of first-language phonological function (i.e., attunement to the phonological identity of words) associated with the “vocabulary explosion” at 18 months. In a preliminary investigation of the relationship between L2 perception and vocabulary size, Japanese learners of Australian English identified Australian English vowels, provided goodness of fit ratings, and completed a vocabulary size questionnaire. We adopted a “whole-system” approach, allowing learners to apply all native vowel system possibilities to the full L2 vowel system. Learners with a larger L2 vocabulary were more consistent in their vowel assimilation patterns, compatible with the L2 perceptual assimilation model.

The various descriptions of schizophrenic language have concentrated on a structural treatment of the schizophrenic's spoken or written language or an elucidation of the relationship between linguistic and cognitive disturbances. The structural treatments in fact often focus on the content of schizophrenic discourse, e.g. circumstantiality, flight of ideas, etc., rather than on grammatical structure. In this paper, the linguistic performance of a chronic schizophrenic, paranoid type (DSM-II:295.3) is examined via a large corpus of continuous spoken and written narrative texts collected over a three-year period. A striking agreement was noted in the oral and written language of this subject in features such as the types of agrammatic errors which occur and extreme perseveration. The data reveal important differences with the six characteristics of schizophrenic language noted by Chaika (1974). A brief comparison is made with aphasic and similar neurolinguistic disturbances suggesting organicity in the present case.

A group of 54 children with specific language impairment was compared with a control group on a referential communication task in which the child was asked to describe a picture from an array of eight similar items so that the listener could identify it. The language-impaired children performed more poorly than age-matched controls. However, there was no relationship between referential communication performance and conversational ability. Children who provided excessive and irrelevant information in conversation did not show the same characteristics in the experimental setting. Formal task requirements, such as the need to scan an array, appeared to be a major determinant of performance on structured referential communication tasks. These tasks are not sensitive to the types of pragmatic difficulty that some children have in open-ended conversation.

The Communicative Intention Inventory, an observational system for describing children's early gestural, vocal, and verbal communicative behaviors, is presented in this paper. The Inventory is comprised of eight intentional categories which are included because of their content and construct validity, their likelihood of occurrence in a clinical setting, and their high observerscorer reliability. The rank order of frequency of occurrence of the eight intentional categories is compared across 16 subjects resulting in a reliability coefficient of .66. The value of using the Inventory as a criterion-referenced measure of communicative intentions is explored.

The longitudinal predictive power of four important reading-related skills (phonological skills, rapid naming, orthographic skills, and morphological awareness) to Chinese word reading and writing to dictation (i.e., spelling) was examined in a 3-year longitudinal study among 251 Chinese elementary students. Rapid naming, orthographic skills, and morphological awareness assessed in Grade 1 were significant longitudinal predictors of Chinese word reading in Grades 1 to 4. As for word spelling, rapid naming was the only significant predictor across grades. Morphological awareness was a robust predictor of word spelling in Grade 1 only. Phonological skills and orthographic skills significantly predicted word spelling in Grades 2 and 4. After controlling for autoregressive effects, morphological awareness and orthographic skills were the significant longitudinal predictors of Chinese word reading and word spelling, respectively. These findings reflected the impacts of the Chinese orthography on children's reading and spelling development.

In this article, I present a selective review of research on speech perception development and its relation to reference, word learning, and other aspects of language acquisition, focusing on the empirical and theoretical contributions that have come from my laboratory over the years. Discussed are the biases infants have at birth for processing speech, the mechanisms by which universal speech perception becomes attuned to the properties of the native language, and the extent to which changing speech perception sensitivities contribute to language learning. These issues are reviewed from the perspective of both monolingual and bilingual learning infants. Two foci will distinguish this from my previous reviews: first and foremost is the extent to which contrastive meaning and referential intent are not just shaped by, but also shape, changing speech perception sensitivities, and second is the extent to which infant speech perception is multisensory and its implications for both theory and methodology.

We analyzed the three main types of English dative constructions – the double-object dative, the to dative, and the for dative – in the spontaneous speech of seven children from the age of 1;6 to 5;0. The main findings were as follows. First, the double-object dative was acquired by most of the children before either of the prepositional datives; this was attributed to the greater frequency with which children heard this construction with individual verbs. Second, the verbs children used with these constructions were not only the adult prototypical ones, but also a number of the less prototypical ones; again, this was very likely due to their frequency and saliency in the language children heard. Third, no support was found for Ninio's (1999) analysis of the emergence of constructions in terms of a single “pathbreaking” verb; rather, children began using the double-object dative with many different verbs and did not follow the trajectory proposed by Ninio (i.e., a single verb is used for some months before an “explosion” of new verbs is introduced in the construction). Finally, most of the verbs initially used in the three dative constructions were first used in other constructions (e.g., a simple transitive); this was even true for some obligatory datives, such as give and show. The current results provide a starting point for determining the underlying representations for the different kinds of dative constructions and for explicating how children understand the interrelations among these and other constructions.

This study examined relationships between oral language and literacy in a two-year, multivariate design. Through empirical cluster analysis of a sample of 88 kindergarten children, four oral language subtypes were identified based on measures of semantics, syntax, metalinguistics, and oral narration. Validation efforts included (a) concurrent and predictive analyses of subtype differences on reading, spelling, and listening comprehension measures based on a priori hypotheses and (b) a comparison of the teacher classification of the children with the empirical classification. The subtypes represented high average, low average, high narrative, and low overall patterns of oral language skill. The high average subtype received the most consistent evidence for validation. The pattern of validation results indicates that the relationship between oral language and literacy is not uniform and suggests a modification of the assumption that oral language skills have a direct role in reading acquisition.

The purpose of this article is to examine the language of girls and boys between 8 and 30 months of age, using the Quebec French version of The MacArthur Communicative Development Inventories. The findings from this parental report measure confirm those of earlier research, which showed the linguistic superiority of girls over boys at a young age. More specifically, the results show that girls produce significantly more words than boys; their utterances contain a greater number of grammatical forms, and are more complex syntactically. On the qualitative level, the data illustrate distinctive characteristics associated with gender in the acquisition of the first 100 words. These findings suggest that caution is necessary when assessing young children to interpret performance in light of factors that may contribute to it, including gender. These results are discussed in light of whether separate normative data are warranted for young boys and girls learning Canadian French.

Herein, we contextualize, problematize, and offer some insights for moving beyond the problem of monolingual comparative normativity in (psycho) linguistic research on bilingualism. We argue that, in the vast majority of cases, juxtaposing (functional) monolinguals to bilinguals fails to offer what the comparison is supposedly intended to do: meet the standards of empirical control in line with the scientific method. Instead, the default nature of monolingual comparative normativity has historically contributed to inequalities in many facets of bilingualism research and continues to impede progress on multiple levels. Beyond framing our views on the matter, we offer some epistemological considerations and methodological alternatives to this standard practice that improve empirical rigor while fostering increased diversity, inclusivity, and equity in our field.

American Sign Language (ASL) provides a unique opportunity to investigate the effects of late exposure to a primary language on adult linguistic processing. In Experiment 1, a video sign-monitoring task was used to investigate the grammatical sensitivity of 11 native signers (exposed to ASL from birth) and 10 late signers (exposed to ASL at a mean age of 12 years) to errors in ASL verb agreement. The results indicated that native signers, but not late signers, were sensitive to errors in verb agreement. Experiment 2 utilized both sign monitoring and off-line grammaticality judgments. Sentences which contained errors in either verb agreement or temporal aspect were presented to 10 native signers, 10 early signers (exposed to ASL between the ages of 2 and 7), and 10 late signers (exposed to ASL between the ages of 10 and 20). The results indicated that native signers were sensitive to errors in both verb agreement and aspect, and that early and late signers were only sensitive to errors in aspect morphology. In the off-line grammaticality test, all three groups were equally able consciously to detect the grammatical errors. These findings suggest that late exposure to a primary language affects the on-line integration of verb agreement information within a sentence, but does not affect sensitivity to semantic distinctions encoded by aspect morphology.

Samples of the communicative behavior of a group of higher-level mentally retarded adults engaged in conversation with peers were examined for indications of mature linguistic competence, specifically, grammatical morpheme and complex sentence use. The findings confirmed the expectation that the eventual level of mastery of these aspects of linguistic competence in higher-level retarded individuals is relatively high. Evidence for a normal developmental progression in the mastery of the grammatical morphemes was also forthcoming. In an analysis of individual complex sentence structures, no relationship was found between relative frequency of use of different types of complex sentences and presumed order of acquisition. However, subjects' ability to combine complex sentences did appear to be related to the presumed order of acquisition, although other factors may have also contributed to this relationship. Unexpectedly, a significant negative correlation was observed between relative frequency of complex sentence use and an estimate of conversational communicative competence. A possible reason for this finding was discussed.

This paper examines the voicing contrast for word-initial obstruents in a child whose functional misarticulation initially was characterized by a severe lack of contrasts normally used in the English language. Specifically, auditory analysis indicated that the child represented a large number of both voiced and voiceless obstruents with [d]. Acoustic analysis demonstrated, however, that the child was producing an obstruent voicing distinction, albeit one that was not generally perceptible to listeners. Following a therapy program, the child produced an acceptable voicing distinction, at least for stops. The importance of these findings is that 1) they seem to indicate that the child is attaining articulation skills in a delayed, and not deviant fashion, and 2) they illustrate the utility of acoustic analyses in refining phonological descriptions.

Emotional content of verbal material affects the speed of visual word recognition in various cognitive tasks, independently of lexicosemantic variables. However, little is known about how the dimensions of emotional arousal and valence interact with the lexicosemantic properties of words such as age of acquisition, familiarity, and imageability, that determine word recognition performance. This study aimed to examine these relationships using English ratings for affective and lexicosemantic features. Eighty-two native English speakers rated 300 words for emotional valence, arousal, familiarity, age of acquisition, and imageability. Although both dimensions of emotion were correlated with lexicosemantic variables, a unique emotion cluster produced the strongest quadratic relationship. This finding suggests that emotion should be included in models of word recognition as it is likely to make an independent contribution.
