The present experiments explored various measures of English and Spanish language ability and compared monolingual and bilingual subjects on tests of cognitive skill. Language ability was assessed in Experiment 1. These measures were found to be highly correlated with each other, with at least two factors needed to describe the associations among the tests in each language. In Experiment 2, subjects were given tests of cognitive skill. To be included in this study, all subjects were required to show adequate understanding of English and were divided into monolingual and bilingual groups on the basis of their Spanish abilities. Monolinguals scored higher than bilinguals on most of the measures of cognitive skill, but subsequent comparisons of the monolinguals with high and low bilingual subgroups suggested that the differences were attributable to those subjects characterized as low bilinguals.

This study investigated the ability of high-functioning verbal adolescents with autism or Down's syndrome to perform a referential communication task. It was predicted that autistic subjects would require more specific prompting to convey needed information to a listener than would subjects with Down's syndrome of the same verbal level. Subjects, 13 with autism and 14 with Down's syndrome, matched on verbal mental age, learned a simple board game, and were asked to teach it to a listener who used varying levels of prompting to elicit target information. Most subjects in the autistic group required specific prompting to produce the target information, whereas most subjects with Down's syndrome did not. Response adequacy was significantly higher in the Down's syndrome group than in the autistic group at the most general prompt level. Subjects with Down's syndrome used more gesture at the most general prompt level and when producing high adequacy responses, whereas subjects with autism used more gesture when producing low adequacy responses.

This study compared the skill in gender attribution of foreign learners and native speakers of French. Accuracy and fluency of gender attribution by the foreign learners were assessed in spontaneous written production. Both groups performed on-line gender assignment to real nouns whose gender was regular or exceptional, given their ending, and to invented nouns with nonword stems and real-word endings. The pattern of results indicated that the native speakers' gender attributions were primarily based on rapidly evoked lexical associations, with gender-ending correspondences playing a significant but subsidiary role. The foreign learners were less able to summon lexical associations, relying heavily on ending-based rules. Overall, none of the foreign learners attained the same level of performance as any of the native speakers. We conclude that instruction in which students learn nouns in the context of distinctive lexical associates could profitably be supplemented by explicit instruction in gender-ending regularities.

Children's heuristics for word learning have been the focus of much research, but little is known about bilinguals' and monolinguals' comparative use of them. In this study, 36 Serbian/ English bilinguals and 42 English monolinguals, who were between 5 and 8 years old and lived in the same neighborhoods in the United States, received a successive name training assessment of two heuristics: criterial use of highlighted features and preservation of mutual exclusivity. Older children employed both heuristics more often than younger ones. Monolinguals were more likely than bilinguals to interpret a highlighted feature as a necessary condition for applying a new English object name, but the groups did not differ in their tendency to maintain mutual exclusivity between the extensions of two novel English labels.

Accurate phenotypic description is critical for the success of studies of the genetic basis for developmental language disorders. An important purpose of such a phenotypic description is to differentiate the language and associated cognitive profiles of syndromes or other developmental language disorders with diverse genotypes. In this paper we consider six measurement issues relevant to genotype/phenotype research and profiling: (a) Who is the target population? (b) What is the “ideal” measure of a single component of language? (c) What is the “ideal” measure(s) for quantifying the language (or language and cognitive) profile for a particular syndrome or disorder? (d) What are the special measurement issues for infants and young children? (e) How do we develop a profile? (f) What are the unresolved issues?

The real-time lexical processing of children with specific language impairment (SLI) was examined, and the focus was to determine whether a temporal processing deficit or a general processing capacity deficit disrupts these children's lexical processing. A group of SLI children (mean age 8;3), a group of age-matched children (CA, mean age 8;1), and a group of receptive syntax-matched children (RS; mean age 6;7) completed a sentence processing task in which they monitored sentences for a target word appearing at the beginning, middle, or end of sentences. Sentences systematically varied with respect to containing either a high proportion of stop consonants (stop-loaded sentences) or a high proportion of nonstop consonants (nonstop-loaded sentences). Children also completed the Identification (ID) Speech Perception Task. On the sentence processing task, SLI children yielded significantly slower word recognition reaction time (RT) overall than both CA and RS controls. Sentence type had no effect on any subject group's RT. No Group × Sentence Type interaction was found. On the ID task, SLI children performed significantly worse than CA controls but similarly to RS children. No correlation was found between temporal processing and lexical processing (for either sentence type or sentences combined) for any group. The findings are interpreted to suggest that a general processing capacity limitation was responsible for the poor ID task performance and slower lexical processing of SLI children.

Previous models of agraphia have been descriptive and have emphasized the association of agraphia with other disorders such as aphasia and alexia. Such models have frequently led to inconsistent descriptions of specific agraphia types. These inconsistencies have made clinical-anatomical correlations difficult. Recent studies of agraphic patients with focal cerebral lesions have made it possible to develop a new model of writing based on specific neuropsychological mechanisms. In addition, results from computerized tomography have helped delineate probable anatomic substrates for many of these mechanisms. It is hoped this model provides a means for a better understanding of the mechanisms and anatomy underlying the agraphias as well as a better understanding of the relationships of the agraphias with aphasia and alexia.

In Experiment 1, 42 multilinguals were able to maintain native language writing quality and fluency in the presence of unattended irrelevant speech while maintaining a concurrent 6-digit memory load. In Experiment 2, 80 bilinguals reduced fluency during writing with the 6-digit load only. In previous research, over 100 monolinguals of comparable verbal and nonverbal skills in three experiments reduced quality and fluency under both secondary tasks (Ransdell, Levy, & Kellogg, 1996). The results are interpreted in terms of a bilingual skill advantage in suppressing irrelevant information. Possessing fluency in another language may confer long-term working memory benefits during dual-task language conditions for bilinguals and even more so for multilinguals.

Native speakers of Mandarin who learn English as a second language (L2) frequently misidentify unreleased tokens of /t/ and /d/ in the final position of English words. The purpose of this study was to evaluate two training methods that might be used to increase Mandarin adults’ accuracy in identifying such stops. Subjects were assigned to receive training using a two-alternative forced-choice procedure or a categorical same/different discrimination procedure. Small but significant increases in the percentage of correct identifications of /t/ and /d/ tokens were obtained for both groups of native Mandarin subjects, although their gains did not differ significantly. These gains were still evident for both groups 2 months after completing the training. The effect of training for both groups generalized to words that were not used in training. Contrary to the hypothesis that identification training promotes more robust long-term memory representations than same/different training, the magnitude of generalization observed for the two groups did not differ significantly. However, subjects seemed to maintain the effects of the same/different training better than the effects of the identification training. Taken together, the results obtained here challenge the view that identification training is superior to same/different training as a means for training novel phonetic contrasts.

The purpose of this study was to investigate word reading abilities in first and third grade Spanish-speaking children who were learning to read in Spanish; the performance of skilled and less skilled readers was compared across measures that assessed phonological recoding ability, knowledge of grapheme-phoneme correspondences, and phonemic awareness. The findings suggest that Spanish-speaking children relied on phonological recoding strategies in the process of becoming readers. First grade, less skilled readers seemed to depend on partial letter-sound knowledge. Furthermore, spelling-sound correspondences appeared to be the main source of information used by first grade, skilled readers and third grade, less skilled readers. The latter seemed to lag behind skilled readers in the use of word-specific information. The phonemic awareness tasks displayed moderate to low correlations with reading ability in the less skilled groups. It is argued that the simple phonological structure of Spanish and its shallow orthography lead to the phonological processing of letter strings during reading acquisition.

The production of passive sentences by children with specific language impairment (SLI) was studied in two languages, English and Cantonese. In both languages, the word order required for passive sentences differs from the word order used for active sentences. However, English and Cantonese passive sentences are quite different in other respects. We found that English-speaking children with SLI were less proficient than both same-age and younger typically developing peers in the use of passives, although difficulty could not be attributed to word order or a reliance on active sentences. Cantonese-speaking children with SLI proved less capable than same-age peers in their use of passive sentences but at least as proficient as younger peers. The implications of these cross-linguistic differences are discussed.

We investigate the production of relative clauses in Italian children aged 3 years, 4 months to 8 years, 10 months and in adults, focusing on object relatives (ORs). For both adults and older children, we test the production of passive ORs (PORs) as an alternative to the production of active ORs. We also test the comprehension of active ORs and PORs in older children, showing that the comprehension of the latter is significantly more accurate than the former. The persistent difficulty that children experience with ORs is interpreted as due to intervention, following Friedmann, Belletti, and Rizzi (2009). We assume Collins’ (2005) approach to passive and account for the increasing use and more accurate comprehension of PORs as a consequence of lack of intervention, as in Belletti (2009a).

Recent research has indicated that learners exposed to second language words’ orthographic forms of words can often use this information to make inferences about the words’ phonological forms. Here we asked, do learners benefit even when the orthography is unfamiliar? We taught native English speakers minimal nonword pairs differentiated by the Arabic velar–uvular contrast (e.g., [kubu], [qubu]) and manipulated the quality of orthographic input. We found that participants were consistently unable to associate the novel phonemes with novel words. Results are discussed in terms of (a) the role of orthographic input in second language word form learning, (b) the influence of orthographic familiarity in moderating the role of orthographic input, and (c) the issue of talker variability in word learning.

We have compared the verbal comprehension abilities of 34 right hemisphere damaged patients to 16 hospitalized control subjects of comparable age and educational attainment. The right hemisphere damaged patients performed as well as the control subjects on a vocabulary test, but were impaired in their ability to interpret proverbs and comprehend logico-grammatical sentences. Impairment on the proverbs test was the result of a decrease in the number of abstract interpretations, whereas impairment on the logico-grammatical sentence comprehension test was related to difficultes in grasping spatial and passive relationships. These comprehension impairments tended to correlate with visuospatial deficits and hemianopia, but not with the degree of hemiparesis or the presence of sensory extinction. Patients with anterior right hemisphere damage performed better on the logico-grammatical sentence conprehension test than patients with posterior damage. A variety of factors probably contribute to these verbal deficits including impaired intellect, inattention, an inability to grasp spatial relationships, and difficulties in manipulating the inner schemata of language.

This study examines the perception and processing of the Catalan /e/–/ɛ/ and /o/–/ɔ/ vowel contrasts by 60 Spanish–Catalan bilinguals in Majorca (Spain). Results from binary forced-choice identification, AX discrimination, and lexical decision tasks show that even though these early and highly proficient bilinguals demonstrate a high accuracy in perceptual identification and discrimination tasks, they have difficulties distinguishing between words and nonwords in a lexical decision task. Spanish dominants also exhibited higher error rates than Catalan dominants in the lexical decision task. These findings provide evidence that making explicit judgments regarding whether a certain sound belongs to a phonemic category (i.e., as accomplished via identification and discrimination tasks) does not entail that listeners have an appropriate representation at the lexical level.

In the context of 90 adult Japanese learners of English with diverse second language experience and 10 native speakers, this study examined the linguistic characteristics and learner profiles of low-, mid- and high-level fluency performance. The participants’ spontaneous speech samples were initially rated by 10 native listeners for global fluency on a 9-point scale (1 = dysfluent, 9 = very fluent), and then divided into four proficiency groups via cluster analyses: low (n = 29), mid (n = 30), high (n = 31), and native (n = 10). Next, the data set was analyzed for the number of pauses within/between clauses, articulation rate, and the frequency of repetitions/self-corrections. According to the results of a series of analyses of variance, the frequency of final-clause pauses differentiated low- and mid-level fluency performance; the number of mid-clause pauses differentiated mid- and high-level performance; and articulation rate differentiated high-level and nativelike performance. The analyses also found that the participants’ second language fluency was significantly associated with their length of residence profiles (0–18 years), but not with their age of arrival profiles (19–40 years).

Two studies explored the relation between listening comprehension of text and listening comprehension of sentences in preschoolers aged 4 to 5 years, 11 months. The first study analyzed this relationship taking into account the role of lower level components, namely, word knowledge and verbal working memory, as possible mediators. These components specifically accounted for listening text comprehension, whereas sentence comprehension did not. Given that sentences forming a text are not processed in isolation but in context, the second study explored the role of the ability to use linguistic context, a higher level component, in listening comprehension of text and sentences. Listening sentence comprehension was facilitated by the use of context, which accounted for individual differences in listening text comprehension. Overall, results showed that listening text comprehension is related to lower level as well as higher level components, whereas listening sentence comprehension does not play a specific role.

This study investigated the role of typological relatedness, language of the community, and age, in predicting similarities and differences between English–Italian, Spanish–Italian bilingual children and their monolingual child and adult counterparts in the acceptability of pre- and postverbal object pronouns in [±focus] contexts in Italian and in English. Cross-linguistic influence occurred in [−focus] contexts as a function of typological relatedness and language of the community. English–Italian bilinguals in the UK accepted pragmatically inappropriate postverbal pronouns in [−focus] contexts in Italian twice as often as all the other groups. Cross-linguistic influence was unidirectional from English to Italian as shown by the categorical rejection of preverbal pronouns in [−focus] contexts in English. In [+focus] contexts, in English no significant differences existed between the monolinguals and the bilinguals in the low accuracy with which they chose pragmatically appropriate stressed pronouns. Similarly, the choice of appropriate pronouns in [+focus] contexts in Italian was problematic for monolingual and bilingual children irrespective of the language of the community and of the bilinguals’ other language. Age was a factor only for the Italian children who approached adultlike performance in [+focus] contexts only by the age of 10. These findings point to the need for a multifaceted approach to account for similarities and differences between the linguistic behavior of bilingual and monolingual children.

This paper explores tense and agreement marking in the spontaneous production of verbs in Arabic-speaking children with specific language impairment (SLI) and two groups of typically developing children: one group matched for mean length of utterance, and the other group matched for age. The special characteristics of Arabic such as its rich bound morphology, intricate verb system, null subject properties, and lack of an infinitival form make it particularly valuable for determining universal versus language-specific aspects of SLI. The results indicate that the Arabic-speaking participants with SLI had obvious problems with verb morphology. They were significantly different from the two comparison groups of children on the percentage of correct use of tense and subject–verb agreement forms. Furthermore, when an error in verbal infection occurred, the substitute form was often an imperative form. The findings are examined in light of cross-linguistic research pertaining to the nature of the SLI deficit and its relationship with typical language learning.

This study examines if type of learner-modified output differentially demonstrates noticing and whether or not this relationship holds in both face-to-face (FTF) and synchronous computer-mediated chat (SCMC) environments. Twenty-four learners of Spanish as a foreign language interacted one-on-one with an interlocutor in the FTF and the SCMC modes, during which they received corrective feedback. After each interaction, learners participated in a mode-specific stimulated recall session to measure their noticing of feedback. Data were coded for (a) feedback episode, (b) type of modified output (none, partial, or full), and (c) accurate noticing. Binary logistic regressions indicated that after feedback, partial modified output was the greatest predictor of accurate noticing of feedback. This finding applied in both FTF and SCMC.
