English Prosodic Focus Marking by Cantonese Trilingual Children With and Without Autism Spectrum Disorder.

The current study investigated English prosodic focus marking by autistic and typically developing (TD) Cantonese trilingual children, and examined the potential differences in this regard compared to native English-speaking children. Forty-eight participants were recruited with 16 speakers for each of the three groups (Cantonese-speaking autistic [CASD], Cantonese-speaking TD [CTD], and English-speaking TD [ETD] children), and prompt questions were designed to elicit desired focus type (i.e., broad, narrow, and contrastive focus). Mean duration, mean fundamental frequency (F0), F0 range, mean intensity, and F0 curves were used as the acoustic correlates for linear mixed-effects model fitting and functional data analyses in relation to groups and focus conditions (i.e., broad, narrow, and contrastive pre-, on-, and post-focus). The CTD group had post-focus compression (PFC) patterns via reducing mean duration, narrowing F0 range, and lowering mean F0, F0 curve, and mean intensity for words under both narrow and contrastive post-focus conditions, while the CASD group only had shortened mean duration and lowered F0 curves. However, neither the CTD group nor CASD group showed much of on-focus expansion (OFE) patterns. The ETD group marked OFE by increasing mean duration, mean F0, mean intensity, and higher F0 curve for words under on-focus conditions. The CTD group utilized more acoustic cues than the CASD group when it comes to PFC. The ETD group differed from the CASD and CTD groups in the use of OFE. Furthermore, both the CASD and CTD groups showed positive first language transfer in the use of duration and intensity and, potentially, successful acquisition in the use of F0 for prosodic focus marking. Meanwhile, the differences in the use of OFE between the Cantonese-speaking and English-speaking groups, not PFC, might indicate that Cantonese-speaking children acquire PFC prior to OFE.

Orthographic Depth May Influence the Degree of Severity of Maze Learning Performance in Children at Risk for Reading Disorder

Reading disability (RD), which affects between 5 and 17% of the population worldwide, is the most prevalent form of learning disability, and is associated with underactivation of a universal reading network in children. However, recent research suggests there are differences in learning rates on cognitive predictors of reading performance, as well as differences in activation patterns within the reading neural network, based on orthographic depth (i.e., transparent/shallow vs. deep/opaque orthographies) in children with RD. Recently, we showed that native English-speaking children with RD exhibit impaired performance on a maze learning task that taps into the same neural networks that are activated during reading. In addition, we demonstrated that genetic risk for RD strengthens the relationship between reading impairment and maze learning performance. However, it is unclear whether the results from these studies can be broadly applied to children from other language orthographies. In this study, we examined whether low reading skill was associated with poor maze learning performance in native English-speaking and native German-speaking children, and the influence of genetic risk for RD on cognition and behavior. In addition, we investigated the link between genetic risk and performance on this task in an orthographically diverse sample of children attending an English-speaking international school in Germany. The results from our data suggest that children with low reading skill, or with a genetic risk for reading impairment, exhibit impaired performance on the maze learning task, regardless of orthographic depth. However, these data also suggest that orthographic depth influences the degree of impairment on this task. The maze learning task requires the involvement of various cognitive processes and neural networks that underlie reading, but is not influenced by potential differences in reading experience due to lack of text or oral reporting. As a fully automated tool, it does not require specialized training to administer, and current results suggest it may be a practicable screening tool for early identification of reading impairment across orthographies.

Immersion in dual-language programs does not impede children’s native language processing

Aims and Objectives: The benefits of dual-language immersion (DLI) versus English-only classrooms for minority-language speakers’ acquisition of English have been well documented. However, less is known about the effect(s) of DLI on majority-language speakers’ native English skills. Prior studies largely used accuracy-focused measures to index children’s language skills; it is possible that processing-based tasks are more sensitive to the effects of DLI experience. Methodology: Thirty-three monolingual native English-speaking children attending English-only classrooms and thirty-three English-speaking children attending English-Spanish DLI matched in age, gender, nonverbal IQ, and socio-economic status were tested twice, 1 year apart, on standardized and processing-based measures of English vocabulary and morphosyntax. Analysis: We ran linear mixed-effects models to examine the extent to which group and time would predict scores on knowledge-based measures of vocabulary and morphosyntactic knowledge, as well as accuracy and reaction times on processing-based measures of English vocabulary and morphosyntax. Findings: Results revealed comparable levels of growth in English for both groups. A subtle effect of DLI was observed on a lexical-decision task: bilinguals were slower in Year 1 but both groups were equally efficient in Year 2. These results indicate that DLI programs have minimal impact on majority-language speakers’ native-language skills in the age-range tested. Originality: This study is the first to longitudinally examine processing-based native language outcomes in bilingual children in DLI classrooms. Significance: We do not find evidence that DLI exposure carries a cost to native language development, even when indexed by processing measures. This should reassure parents, educators, and policymakers in that there are no downsides to DLI.

Automatic morpheme identification across development: Magnetoencephalography (MEG) evidence from fast periodic visual stimulation.

The present study combined magnetoencephalography (MEG) recordings with fast periodic visual stimulation (FPVS) to investigate automatic neural responses to morphemes in developing and skilled readers. Native English-speaking children (N = 17, grade 5–6) and adults (N = 28) were presented with rapid streams of base stimuli (6 Hz) interleaved periodically with oddballs (i.e., every fifth item, oddball stimulation frequency: 1.2 Hz). In a manipulation-check condition, tapping into word recognition, oddballs featured familiar words (e.g., roll) embedded in a stream of consonant strings (e.g., ktlq). In the experimental conditions, the contrast between oddball and base stimuli was manipulated in order to probe selective stem and suffix identification in morphologically structured pseudowords (e.g., stem + suffix pseudowords such as softity embedded in nonstem + suffix pseudowords such as trumess). Neural responses at the oddball frequency and harmonics were analyzed at the sensor level using non-parametric cluster-based permutation tests. As expected, results in the manipulation-check condition revealed a word-selective response reflected by a predominantly left-lateralized cluster that emerged over temporal, parietal, and occipital sensors in both children and adults. However, across the experimental conditions, results yielded a differential pattern of oddball responses in developing and skilled readers. Children displayed a significant response that emerged in a mostly central occipital cluster for the condition tracking stem identification in the presence of suffixes (e.g., softity vs. trumess). In contrast, adult participants showed a significant response that emerged in a cluster located in central and left occipital sensors for the condition tracking suffix identification in the presence of stems (e.g., softity vs. stopust). The present results suggest that while the morpheme identification system in Grade 5–6 children is not yet adult-like, it is sufficiently mature to automatically analyze the morphemic structure of novel letter strings. These findings are discussed in the context of theoretical accounts of morphological processing across reading development.

Higher access to screens is related to decreased functional connectivity between neural networks associated with basic attention skills and cognitive control in children

ABSTRACT Screen-based media has become a prevailing part of children’s lives. Different technologies provide limitless access to a wide range of content. This accessibility has immensely increased screen exposure among children, showing that this exposure is associated with decreased cognitive abilities. This study was designed to evaluate how the neurobiological correlates for different sub-components of screen exposure, such as level of access, content, and frequency, are related to different cognitive abilities. Resting-state functional MRI data were collected in 29 native English-speaking children (8–12 years old), in addition to cognitive-behavioral measures. Functional connectivity measures within and between several networks related to cognitive control and attention were calculated [fronto-parietal (FP), cingulo-opercular (CO), dorsal attention (DAN), ventral attention (VAN), salience, default mode (DMN), cerebellar networks]. Sub-components of screen exposure were measured using the Screen-Q questionnaire. Higher access to screens was related to lower functional connectivity between neural networks associated with basic attention skills and cognitive control (i.e., DAN and salience). In addition, higher levels of parent-child interaction during screen exposure were related to increased functional connectivity between networks related to cognitive control and learning (i.e., CO and cerebellar). These findings suggest that screen exposure may reduce the engagement of basic attention and modulation of cognitive control networks and that higher levels of parent-child interaction engage cognitive control networks. An enhanced understanding of these processes can provide an important scientific basis for future educational and medical approaches regarding screen exposure.

The role of accent and speaker certainty in children's selective trust

Native English-speaking children prefer native English speakers over foreign-accented English speakers (Girard & Goslin, 2008; Kinzler et al., 2009; Kinzler et al., 2011). Young children also tend to distrust speakers who use uncertain language (e.g., “I guess,” “I’m not sure”) relative to those who use certain language (e.g., “I know, I’m sure”; Jaswal & Malone, 2007; Kim et al., 2012; Koenig & Harris, 2005). The present study asks how information about the speaker’s certainty interacts with the speaker’s accent. In particular, we asked whether speakers who are perceived as less reliable (foreign-accented individuals) are perceived as more reliable when they provide linguistic cues to certainty. We showed 89 typically developing monolingual native English-speaking 3- to 6- year-olds from North America pairs of videos in which two possible functions for a novel toy were introduced. We manipulated three variables: (1) whether the speaker introducing each function was a native- or foreign-accented English speaker; (2) whether the speaker expressed certainty or uncertainty about the function of the object; and (3) whether the experimenter who interacted with the child was a native- or foreign-accented English speaker. We found a strong preference to learn from native speakers, and found that this preference was impacted by the use of certain vs. uncertain language. These data are important for what they tell us about how children weigh different sources of information when deciding who to learn from. They are also of practical importance: if children are less likely to want to learn from foreign-accented speakers, then this has large implications for caregivers and educators.

Sociopragmatic competence in American and Chinese children’s realization of apology and refusal

This study explores the cross-cultural difference in the change of sociopragmatic competence by collecting perception and production data from native English-speaking children and native Mandarin Chinese-speaking children. The study focused on the development of interlocutor sensitivity in the realization of speech acts of apology and refusal. The participants consisted of four groups: American 1st-grade, American 8th-grade, Chinese 1st-grade and Chinese 8th-grade students. The children’s interlocutor sensitivity was examined through the following aspects: (1) their perception of severity of the offense, (2) their perception of the “need to be more polite” when apologizing to or refusing a familiar interlocutor or an interlocutor with higher social status, and (3) the use of apology and refusal strategies. The results showed that cross-cultural differences exist in the change pattern of interlocutor variation.

Verb Variability and Morphosyntactic Priming With Typically Developing 2- and 3-Year-Olds.

This study was specifically designed to examine how verb variability and verb overlap in a morphosyntactic priming task affect typically developing children's use and generalization of auxiliary IS. Forty typically developing 2- to 3-year-old native English-speaking children with inconsistent auxiliary IS production were primed with 24 present progressive auxiliary IS sentences. Half of the children heard auxiliary IS primes with 24 unique verbs (high variability). The other half heard auxiliary IS primes with only 6 verbs, repeated 4 times each (low variability). In addition, half of the children heard prime-target pairs with overlapping verbs (lexical boost), whereas the other half heard prime-target pairs with nonoverlapping verbs (no lexical boost). To assess use and generalization of the targeted structure to untrained verbs, all children described probe items at baseline and 5 min and 24 hr after the priming task. Children in the high variability group demonstrated strong priming effects during the task and increased auxiliary IS production compared with baseline performance 5 min and 24 hr after the priming task, suggesting learning and generalization of the primed structure. Children in the low variability group showed no significant increases in auxiliary IS production and fell significantly below the high variability group in the 24-hr posttest. Verb overlap did not boost priming effects during the priming task or in posttest probes. Typically developing children do indeed make use of lexical variability in their linguistic input to help them extract and generalize abstract grammatical rules. They can do this quite quickly, with relatively stable, robust learning occurring after a single optimally variable input session. With reduced variability, learning does not occur.

Item response theory analyses of the Delis-Kaplan Executive Function System card sorting subtest

ABSTRACTIn the current study, we examined the dimensionality of the 16-item Card Sorting subtest of the Delis-Kaplan Executive Functioning System assessment in a sample of 264 native English-speaking children between the ages of 9 and 15 years. We also tested for measurement invariance for these items across age and gender groups using item response theory (IRT). Results of the exploratory factor analysis indicated that a two-factor model that distinguished between verbal and perceptual items provided the best fit to the data. Although the items demonstrated measurement invariance across age groups, measurement invariance was violated for gender groups, with two items demonstrating differential item functioning for males and females. Multigroup analysis using all 16 items indicated that the items were more effective for individuals whose IRT scale scores were relatively high. A single-group explanatory IRT model using 14 non-differential item functioning items showed that for perceptual ability, females scored higher than males and that scores increased with age for both males and females; for verbal ability, the observed increase in scores across age differed for males and females. The implications of these findings are discussed.

Young learners’ response processes when taking computerized tasks for speaking assessment

We investigated how young language learners process their responses on and perceive a computer-mediated, timed speaking test. Twenty 8-, 9-, and 10-year-old non-native English-speaking children (NNSs) and eight same-aged, native English-speaking children (NSs) completed seven computerized sample TOEFL®Primary™ speaking test tasks. We investigated the children’s attentional foci on different test components (e.g., prompts, pictures, and a countdown timer) by means of their eye movements. We associated the children’s eye-movement indices (visit counts and fixation durations) with spoken performance. The children provided qualitative data (interviews; picture-drawings) on their test experiences as well. Results indicated a clear contrast between NNSs and NSs in terms of speech production (large score differences) as expected. More interestingly, the groups’ eye-movement patterns differed. NNSs tended to fixate longer on and looked more frequently at the countdown timer than their NS peers, who were more likely to look at content features, that is, onscreen pictures meant to help with building up speech. Specifically, the NNSs’ fixations on timers were likely to co-occur with hesitation phenomena (e.g., hemming; pausing; silence). We discuss (a) the potential effects of test-specific features on children’s performance and (b) child-appropriate test accommodations and practices.

The representation and execution of articulatory timing in first and second language acquisition

The early acquisition of language-specific temporal patterns relative to the late development of speech motor control suggests a dissociation between the representation and execution of articulatory timing. The current study tested for such a dissociation in first and second language acquisition. American English-speaking children (5- and 8-year-olds) and Korean-speaking adult learners of English repeatedly produced real English words in a simple carrier sentence. The words were designed to elicit different language-specific vowel length contrasts. Measures of absolute duration and variability in single vowel productions were extracted to evaluate the realization of contrasts (representation) and to index speech motor abilities (execution). Results were mostly consistent with a dissociation. Native English-speaking children produced the same language-specific temporal patterns as native English-speaking adults, but their productions were more variable than the adults’. In contrast, Korean-speaking adult learners of English typically produced different temporal patterns than native English-speaking adults, but their productions were as stable as the native speakers’. Implications of the results are discussed with reference to different models of speech production.

Exploring minority language input sources as means of supporting the early development of second language vocabulary and grammar

ABSTRACTExposure to a minority language is largely limited in terms of frequency, and often delivered by nonnative speakers in certain domains. This study aimed to evaluate the effectiveness of two types of native-language input sources (story telling and minority language children's television) in providing 4- and 5-year-old native English-speaking children with beginning awareness of Welsh. Results revealed that exposure to Welsh via television programs was equally as beneficial, if not more so in some cases, as listening to Welsh stories in developing children's vocabulary, particularly within the context of social interaction. These results suggest a useful and potentially effective role for the use of native-language television within a carefully designed language curriculum to aid early second language development in minority language contexts.

The development of stress sensitivity and its contribution to word reading in school-aged children.

This study examined the development of stress sensitivity and its relationship with word reading. Previous research has rarely measured phoneme and stress sensitivity in the same task, making a direct comparison of the contribution between the two in reading development difficult. Participants were native English-speaking adults and children at ages of 6, 8, and 10 years (N = 24, 22, 22, and 24, respectively). A lexical decision task was used to measure both stress and phoneme sensitivity. Oral vocabulary, phoneme awareness, and word reading were assessed. Stress sensitivity accounted for unique variance in reading over and above vocabulary and phoneme awareness in 6-year-olds. Both adults and children had better phoneme sensitivity than stress sensitivity. These findings highlight the unique contribution of stress sensitivity in reading development. The current study made a novel contribution to studying the relationship between prosody and literacy by utilising a task that is able to assess children's stress and phoneme sensitivity simultaneously.

Assessing successive bilinguals in two languages: A longitudinal look at English-speaking children in France

This study examines longitudinal standardized test scores in both languages of a group of successive bilinguals with L1 English acquiring L2 French. Participants included 22 native English-speaking children living in France. French was evaluated using a standardized receptive vocabulary test, as well as tests of phonology and morphosyntax. English was evaluated using the Core Language Score subtests from the CELF-4-UK. The children varied in age (6;9–12;7) and length of exposure (0;11–3;9) to French and were tested twice at 12-month intervals. At T1, 7 children scored below norms in both languages, while only 3 did so at T2. Two out of these 3 were arguably not typically developing children. Length of exposure to French emerged as an important factor only at T1, when a number of children were in early stages of acquisition (≤18months of exposure). English scores varied by age and weekly use of English. In successive bilingual children, language performance on L2 standardized tests can be expected to be (well) below norms during the first 18 months of exposure. English scores revealed that weak L1 performance is part of typical development in this bilingual context, but that L1 retention is also a possibility. Learning outcomesThe reader will be able to: (1) describe challenges associated with language assessment of successive bilingual children, (2) describe the impact that age and length of exposure can have on language performance in bilinguals, and (3) understand how assessing successive bilinguals using monolingual norms can lead to underestimation of language abilities.

Bilingualism and phonological awareness: Re-examining theories of cross-language transfer and structural sensitivity

The purpose of this study was to examine the relationship between bilingualism and phonological awareness by re-evaluating structural sensitivity theory and expanding cross-language transfer theory. The study was conducted with three groups of 1st and 2nd graders matched in age, SES and nonverbal IQ: a) monolingual English-speaking children from a general education program, b) native Japanese-speaking children from a Japanese–English two-way immersion bilingual program and c) native English-speaking children from the same bilingual program. An odd-man-out task that took into account the phonological and orthographical contrasts between English and Japanese was developed to assess onset awareness. The results showed that the bilingual children outperformed their monolingual peers in processing onsets that are shared between the two languages, which provided empirical support for the first hypothesis derived from structural sensitivity theory and highlighted the importance of contextual variability in bilingual metalinguistic processing. The second hypothesis derived from structural sensitivity theory, which predicated that bilingual advantage would be more evident in processing novel stimuli, was not confirmed in the present study. The absence of the predicted group difference may be attributed to the disparity in the extent of novelty of the stimuli and the difference in the comparability of participants' degrees of bilingualism between the present study and previous research. Finally, expanding existing research, results from this study showed that cross-language transfer can occur at a phonetic featural level. Future research and theoretical implications were discussed.

Up or down? Reading direction influences vertical counting direction in the horizontal plane - a cross-cultural comparison.

Most adults and children in cultures where reading text progresses from left to right also count objects from the left to the right side of space. The reverse is found in cultures with a right-to-left reading direction. The current set of experiments investigated whether vertical counting in the horizontal plane is also influenced by reading direction. Participants were either from a left-to-right reading culture (UK) or from a mixed (left-to-right and top-to-bottom) reading culture (Hong Kong). In Experiment 1, native English-speaking children and adults and native Cantonese-speaking children and adults performed three object counting tasks. Objects were presented flat on a table in a horizontal, vertical, and square display. Independent of culture, the horizontal array was mostly counted from left to right. While the majority of English-speaking children counted the vertical display from bottom to top, the majority of the Cantonese-speaking children as well as both Cantonese- and English-speaking adults counted the vertical display from top to bottom. This pattern was replicated in the counting pattern for squares: all groups except the English-speaking children started counting with the top left coin. In Experiment 2, Cantonese-speaking adults counted a square array of objects after they read a text presented to them either in left-to-right or in top-to-bottom reading direction. Most Cantonese-speaking adults started counting the array by moving horizontally from left to right. However, significantly more Cantonese-speaking adults started counting with a top-to-bottom movement after reading the text presented in a top-to-bottom reading direction than in a left-to-right reading direction. Our results show clearly that vertical counting in the horizontal plane is influenced by longstanding as well as more recent experience of reading direction.

Fluence et prononciation de phonèmes en L1 et L2

Learning how to read is an important step in a child’s education. Our longitudinal study focuses on four native English-speaking children going to a French immersion school in the United States, as well as their families. These children learn to read in French, which is a foreign language to them. We aimed at finding out whether their home environment could explain good results in reading in the two languages: English, their mother tongue, and French, the foreign language, as Cummins (1981) suggests. To this end, we measured their performance in reading through their pronunciation and their reading fluency, and we had their family complete a questionnaire about their reading habits at home. The results show that the home environment does seem to play a role in the children’s performance but more generalizations must await further research.

Self-concept and native language background: A study of measurement invariance and cross-group comparisons in third grade.

This study examined the measurement and interpretation of self-concept among the growing population of children who are English Language Learners (ELLs). More specifically, a 3-group analysis was conducted comparing native English-speaking children, Spanish-speaking ELLs, and ELLs from Asian language backgrounds. Data were drawn from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (Pollack, Atkins-Burnett, Rock, & Weiss, 2005), in which an adapted version of the Self-Description Questionnaire–I (SDQ-I; Marsh, 1990b) was used to measure children's self-concept in 3rd grade. Participants were 11,020 native English-speaking children, 1,277 Spanish-speaking ELLs, and 546 ELLs from Asian language backgrounds. Multigroup confirmatory factor analyses showed that the SDQ-I measured self-concept similarly across children from all 3 language groups. Cross-group comparisons of latent means indicated significant differences in academic self-concept, with Spanish-speaking ELLs reporting higher academic self-concept in reading, mathematics, and all school subjects compared to native English-speaking children. Asian language ELLs reported higher academic self-concept than native English-speakers only in the subject of mathematics. Regarding social-emotional self-concept, Spanish-speaking ELLs reported significantly more internalizing and externalizing problems compared to native English-speaking children, whereas Asian language ELLs reported fewer externalizing problems. ELLs from Asian language backgrounds also rated themselves significantly lower on peer relationships. The authors discuss implications for researchers and educators and offer suggestions for future areas of study.

Room acoustic effects on speech comprehension by English-as-a-second-language versus native English-speaking listeners

English-as-a-second-language (ESL) listeners are generally more impaired than native English-speaking listeners on speech intelligibility tasks under reverberation and noise; however, more study is needed to ascertain these groups’ performances on speech comprehension tasks, rather than intelligibility. A recent study (Valente et al, 2012) showed that speech comprehension by both native English-speaking adults and children was more negatively affected by adverse acoustic environments than sentence recognition. The current project investigates the speech comprehension of both ESL and native English-speaking adult listeners under combinations of reverberation and noise. Sets of 15-minute long listening comprehension tests based on the format of the Test of English for International Communication (TOEIC) were developed, anechoically recorded, convolved with binaural room impulse responses (BRIRs) to produce five mid-frequency reverberation times (0.4 to 1.1 seconds), and presented over loudspeakers in the Nebraska acoustics chamber. Background noise was also varied at three levels (RC-30, 40 and 50) through an Armstrong i-Ceiling system. In total then, subjects were individually exposed to 15 acoustic combinations of reverberation and background noise. Preliminary results will be presented and compared between ESL and native English listeners. [Work supported by a UNL Durham School Seed Grant and the Paul S. Veneklasen Research Foundation.]

Predicting literacy achievement in young English language learners: A question of language proficiency or of learning difficulty?

In this article empirical research regarding the best predictors of literacy achievement for English language learning students (ELLs) in English-only classrooms is reviewed. These students comprise an ever-increasing population in these settings, but there is considerable confusion in differentiating between ELLs who are low-achievement readers because of limited language proficiency and those who may have learning difficulties. Much research has highlighted the importance of phonological processes, particularly phonological awareness, on reading achievement for native English-speaking children and it seems that researchers have relatively recently begun to examine whether or not the same might hold for ELL children. The findings regarding this under-researched population are discussed and implications and recommendations for future research and practice are proposed.
