Language Group Differences Research Articles

“I Readed the Book Last Week.” The Role of Dominant Language, Receptive Vocabulary and Language Structure on Morphosyntactic Awareness in Monolingual and Heritage Language Children

In this research, 5- and 6-year-old monolingual (English) and heritage language (English–Spanish, English–Urdu) children completed a grammaticality judgment test to assess their awareness of grammatically correct and incorrect morphosyntactic structures in English. Results demonstrated that language group differences were minimized when heritage language children exhibited average receptive vocabulary proficiency for the sample, and when more difficult morphosyntactic structures were assessed. In this middle range, only two group differences were found. Our findings highlight the need to consider factors such as receptive vocabulary when assessing morphosyntactic awareness and language group differences.

Early Literacy and Numeracy Skills in Bilingual Minority Children: Toward a Relative Independence of Linguistic and Numerical Processing.

Many studies have suggested that the concept of “number” is relatively independent from linguistic skills, although an increasing number of studies suggest that language abilities may play a pivotal role in the development of arithmetic skills. The condition of bilingualism can offer a unique perspective into the role of linguistic competence in numerical development. The present study was aimed at evaluating the relationship between language skills and early numeracy through a multilevel investigation in monolingual and bilingual minority children attending preschool. The sample included 156 preschool children. Of these, 77 were bilingual minority children (mean age = 58.27 ± 5.90), and 79 were monolinguals (mean age = 58.45 ± 6.03). The study focused on three levels of analysis: group differences in language and number skills, concurrent linguistic predictors of early numeracy and, finally, profile analysis of linguistic skills in children with impaired vs. adequate numeracy skills. The results showed that, apart from the expected differences in linguistic measures, bilinguals differed from monolinguals in numerical skills with a verbal component, such as semantic knowledge of digits, but they did not differ in a pure non-verbal component such as quantity comparison. The multigroup structural equation model indicated that letter knowledge was a significant predictor of the verbal component of numeracy for both groups. Phonological awareness was a significant predictor of numeracy skills only in the monolingual group. Profile analysis showed that children with a selective weakness in the non-verbal component of numeracy had fully adequate verbal skills. Results from the present study suggest that only some specific components of language competence predict numerical processing, although linguistic proficiency may not be a prerequisite for developing adequate early numeracy skills.

Investigating the relationship between bilingualism, cognitive control, and mind wandering

ABSTRACTSome research has suggested that bilingualism produces cognitive control advantages, although it has recently been shown that reported advantages are influenced by a publication bias. If the bilingual (BL) advantage does exist, the specific causes and contexts for its appearance remain unclear. The purpose of the current study was twofold: one, to examine performance of BLs and monolinguals (MLs) on a variety of simple versus complex cognitive control tasks; and two, to determine whether there were language group differences in the tendency to mind wander, which has been heavily implicated in cognitive control tasks. Although we hypothesised that if BLs outperformed MLs on cognitive control tasks, this would be associated with less mind wandering for BLs, the results did not reveal any BL advantages or any differences in mind-wandering tendencies. These findings support calls to temper BL advantage claims and shows a need for future research to better specify which underlying factors of cognitive control may be optimised by multilingualism.

Maternal Obesity, Overweight and Gestational Diabetes Affect the Offspring Neurodevelopment at 6 and 18 Months of Age--A Follow Up from the PREOBE Cohort.

BackgroundBrain development in fetal life and early infancy is critical to determine lifelong performance in various neuropsychological domains. Metabolic pathologies such as overweight, obesity, and gestational diabetes in pregnant women are prevalent and increasing risk factors that may adversely affect long-term brain development in their offspring.ObjectiveThe objective of this research was to investigate the influence of maternal metabolic pathologies on the neurodevelopment of the offspring at 6 and 18 months of life.DesignThis was a prospective case-control study of 331 mother- and child pairs from Granada, Spain. The mothers were included during pregnancy into four groups according to their pre-gestational body mass index and their gestational diabetes status; overweight (n:56), obese (n:64), gestational diabetic (n:79), and healthy normal weight controls (n:132). At 6 months and 18 months we assessed the children with the Bayley III scales of neurodevelopment.ResultsAt 6 months (n=215), we found significant group differences in cognition composite language, and expressive language. Post hoc test revealed unexpectedly higher scores in the obese group compared to the normal weight group and a similar trend in overweight and diabetic group. The effects on language remained significant after adjusting for confounders with an adjusted odds ratio for a value above median in composite language score of 3.3 (95% CI: 1.1, 10.0; p=0.035) for children of obese mothers. At 18 month (n=197), the offspring born to obese mothers had lost five points in language composite scores and the previous differences in language and cognition was replaced by a suggestive trend of lower gross motor scores in the overweight, obese, and diabetic groups.ConclusionsInfants of obese mothers had a temporary accelerated development of cognition and language, followed by a rapid deceleration until 18 months of age, particularly of language scores. This novel observation prompts further confirmative studies to explore possible placental and neurodevelopmental mechanisms involved.

Morphology and Syntax in Late Talkers at Age 5

This study reports age 5 morphology and syntax skills in late talkers identified at age 2 (n=34) and typically developing comparison children (n=20). The late talkers manifested significant morphological delays at ages 3 and 4 relative to comparison peers. Based on the 14 morphemes analyzed at age 5, the only significant group difference was on the third person regular -s inflection. This was also the only significant difference when we compared late talkers with continuing delay, late bloomers (who scored within 1 standard deviation of the comparison group in mean length of utterance), and typically developing peers. The late talker and comparison children differed greatly in mean total scores on the Index of Productive Syntax (Scarborough, 1990), a measure of syntactic complexity. The group with continuing delay scored significantly lower on the IPSyn than the late bloomer and typically developing groups, which did not differ from each other. Findings are consistent with the higher order language group differences found through adolescence in these late talkers relative to comparison peers with similar socioeconomic status and similar nonverbal abilities, supporting the notion that late talkers have an ongoing weakness in language endowment that manifests differently over the course of development.

Beyond Panglossian Optimism: Larger N2 Amplitudes Probably Signal a Bilingual Disadvantage in Conflict Monitoring

In this special issue on the brain mechanisms that lead to cognitive benefits of bilingualism we discussed six reasons why it will be very difficult to discover those mechanisms. Many of these problems apply to the article by Fernandez, Acosta, Douglass, Doshi, and Tartar that also appears in the special issue. These concerns include the following: 1) an overly optimistic assessment of the replicability of bilingual advantages in behavioral studies, 2) reliance on risky small samples sizes, 3) failures to match the samples on demographic characteristics such as immigrant status, and 4) language group differences that occur in neural measures (i.e., N2 amplitude), but not in the behavioral data. Furthermore the N2 amplitude measure in general suffers from valence ambiguity: larger N2 amplitudes reported for bilinguals are more likely to reflect poorer conflict resolution rather than enhanced inhibitory control.

The dimensions of written expression: Language group and gender differences

This study compared the written expression of 159 English-speaking first (L1) and second language (L2) learners (Mage = 9; 7 years, SD = 3.63 months) in England The L1 learners outperformed their L2 peers on the four dimensions of written expression, namely holistic quality, written vocabulary, organisational quality, and compositional fluency. Girls also outperformed boys on all dimensions, except for organisation. The interaction between language group and gender was nonsignificant, but there was a trend for the language group differences to be larger for boys. Vocabulary, organisation, and compositional fluency made unique contributions to holistic quality in both language groups and the strength of these relations were relatively comparable across the L1 and L2 groups. Educational implications are discussed.

Effects of bilingualism on the age of onset and progression of MCI and AD: Evidence from executive function tests.

Previous articles have reported that bilingualism is associated with a substantial delay in the onset of both Alzheimer's disease (AD) and Mild Cognitive Impairment (MCI). The present study reports results from 74 MCI patients and 75 AD patients; approximately half of the patients in each group were bilingual. All patients were interviewed to obtain details of their language use, onset of their condition, and lifestyle habits. Patients performed three executive function (EF) tests from the D-KEFS battery (Trails, Color-Word Interference, Verbal Fluency) on 3 occasions over a period of approximately 1 year. Results replicated the finding that bilingual patients are several years older than comparable monolinguals at both age of symptom onset and date of first clinic visit. This result could not be attributed to language group differences in such lifestyle variables as diet, smoking, alcohol consumption, physical activity, or social activity. On the first testing occasion, performance on the EF tasks was generally comparable between the language groups, contesting arguments that bilinguals wait longer before attending the clinic. Finally, EF performance tended to decline over the 3 sessions, but no differences were found between monolinguals and bilinguals in the rate of decline.

Auditory scene analysis in school-aged children with developmental language disorders

Natural sound environments are dynamic, with overlapping acoustic input originating from simultaneously active sources. A key function of the auditory system is to integrate sensory inputs that belong together and segregate those that come from different sources. We hypothesized that this skill is impaired in individuals with phonological processing difficulties. There is considerable disagreement about whether phonological impairments observed in children with developmental language disorders can be attributed to specific linguistic deficits or to more general acoustic processing deficits. However, most tests of general auditory abilities have been conducted with a single set of sounds. We assessed the ability of school-aged children (7–15years) to parse complex auditory non-speech input, and determined whether the presence of phonological processing impairments was associated with stream perception performance. A key finding was that children with language impairments did not show the same developmental trajectory for stream perception as typically developing children. In addition, children with language impairments required larger frequency separations between sounds to hear distinct streams compared to age-matched peers. Furthermore, phonological processing ability was a significant predictor of stream perception measures, but only in the older age groups. No such association was found in the youngest children. These results indicate that children with language impairments have difficulty parsing speech streams, or identifying individual sound events when there are competing sound sources. We conclude that language group differences may in part reflect fundamental maturational disparities in the analysis of complex auditory scenes.

Executive function and bilingualism in young and older adults.

Research suggests that being bilingual results in advantages on executive control processes and disadvantages on language tasks relative to monolinguals. Furthermore, the executive function advantage is thought to be larger in older than younger adults, suggesting that bilingualism may buffer against age-related changes in executive function. However, there are potential confounds in some of the previous research, as well as inconsistencies in the literature. The goal of the current investigation was to examine the presence of a bilingual advantage in executive control and a bilingual disadvantage on language tasks in the same sample of young and older monolingual anglophones, monolingual francophones, and French/English bilinguals. Participants completed a series of executive function tasks, including a Stroop task, a Simon task, a sustained attention to response task (SART), the Wisconsin Card Sort Test (WCST), and the digit span subtest of the Wechsler Adult Intelligence Scale, and language tasks, including the Boston Naming Test (BNT), and category and letter fluency. The results do not demonstrate an unequivocal advantage for bilinguals on executive function tasks and raise questions about the reliability, robustness and/or specificity of previous findings. The results also did not demonstrate a disadvantage for bilinguals on language tasks. Rather, they suggest that there may be an influence of the language environment. It is concluded that additional research is required to fully characterize any language group differences in both executive function and language tasks.

Exploring pre-service student-teachers' commitment to community engagement in the second year of training

This preliminary study examines the utility of the Community Engagement Commitment Scale and reports on factors that predict student-teachers' commitment to community engagement in their second year of study at a South African university. Independent variables included Dalbert's personal belief in a just world, an adaptation of Rusbult et al.'s original predictors of Commitment level (Satisfaction, Quality of alternatives, Investment size) and a new factor, Meaningfulness. The latter factor is based theoretically on the work of Lieberman and Heine, Proulx and Vohs and was included to study the extent to which identity-expression could be related to Commitment level. We administered the Community Engagement Commitment Scale on a non-random sample of 414 student-teachers in their second year of study, who all participated in compulsory community engagement project. The results support a four-factor model of Commitment with Meaningfulness, Quality of alternatives and Investment as predictors of Commitment level. Surprisingly, all the Satisfaction items loaded with the Commitment level items on one factor. Together, Meaningfulness, Quality of alternatives and Investment accounted for approximately two-thirds of the variance in Commitment level. Significant (p < .01) language group differences were also observed on Meaningfulness and Commitment level. The results of the study suggest the importance of studying meaningfulness as an additional predictor of Commitment level in community engagement contexts.

Daily Function Impairment is Associated with Cognitive Deficit between Depressed and Remitted Elders

Introduction: Cognitive impairment is frequent in late-life depression (LLD), but its impact on ability to function in daily life has not been systematically evaluated. In the current study, we assessed cognitive and functional status in currently depressed versus remitted older adults. Methods: Participants were 60 older adults who currently met DSM-IV criteria for Major Depressive Disorder (MDD) and 23 remitted MDD patients between the ages of 55-81 years who were recruited from a Geriatric Mood Clinic. Clinical severity of depression was evaluated using the Hamilton Depression Rating Scale. Standard neuropsychological tests were used to assess information processing, verbal and nonverbal episodic memory, language, visuospatial ability and executive function. Functional status was determined using three categories from the Clinical Dementia Rating Scale (CDR): Community Affairs, Home and Hobbies, and Personal Care. Results: Compared to remitted patients, currently depressed older adults had decreased attention (p < .05), nonverbal memory (p < .05), and executive function (p < .05), but there were no group differences in language or visuospatial abilities. Depressed patients had poorer functional abilities in community affairs (p < .05) and household chores and hobbies (p < .01), but not in personal care. Across both groups, functional impairment was correlated with decreased verbal recall, executive function, and information processing speed. Conclusions: Our findings indicate a direct relationship between cognitive and functional impairment in depressed and remitted older adults. These results suggest the need for interventions designed to directly impact on ability to function in LLD, in addition to cognitive or pharmacological interventions.

Detecting native language group differences at the subskills level of reading: A differential skill functioning approach

Differential skill functioning (DSF) exists when examinees from different groups have different probabilities of successful performance in a certain subskill underlying the measured construct, given that they have the same ability on the overall construct. Using a DSF approach, this study examined the differences between two native language groups – a group with an East Asian language background and one with a Romance language background – in regard to reading subskills as represented in the Michigan English Language Assessment Battery (MELAB) reading test. Based on a combination of literature review and think-aloud reports from a sample of ESL students, hypotheses on reading subskill differences between the two groups were generated. These hypotheses were tested by first identifying the subskill profile of each examinee in a large MELAB database via the application of a previously determined item-skill Q-matrix to a Fusion Model of cognitive diagnostic modeling. The subskill profiles of the East Asian examinees were then compared against those of examinees with a Romance language background through logistic regression techniques. Some important DSFs were found between the two groups. Based on results of this study, instructional strategies were suggested to address some specific weaknesses in ESL learners’ reading subskills.

The role of oral language skills in reading and listening comprehension of text: a comparison of monolingual (L1) and bilingual (L2) speakers of English language

The study examined the role of oral language skills in reading comprehension and listening comprehension levels of 125 monolingual (L1) and bilingual (L2) English‐speaking learners (M = 121.5 months, SD = 4.65) in England. All testing was conducted in English. The L1 learners outperformed their L2 peers on the measures of oral language and text comprehension, but the two groups performed at comparable levels on word‐reading accuracy and speed. Oral language, indexed by vocabulary and morphosyntactic skills, emerged as the most powerful unique predictor of both reading and listening comprehension levels. Although there was a tendency of oral language to be more strongly related to L2 reading comprehension, its relationship with listening comprehension was comparable across the two language groups. Finally, individual differences in oral language skills emerged as the primary factor that explained the language group differences in text comprehension levels. Educational implications of these findings were discussed.

Conflict monitoring and resolution: Are two languages better than one? Evidence from reaction time and event-related brain potentials

An advantage for bilingual relative to monolingual young adults has been found for cognitive control tasks, although this finding is not consistent in the literature. The present investigation further examined this advantage using three tasks previously found to be sensitive to the effect. Furthermore, both behavioral and event-related brain potential (ERP) measures were included. Monolingual (n=25) and highly proficient bilingual (n=26) young adults completed a Stroop, Simon, and Eriksen flanker task while electrophysiological recording took place. Behaviorally there were no language group differences on any of the tasks. The ERP measures demonstrated differences between monolinguals and bilinguals with respect to conflict monitoring, resource allocation, stimulus categorization, and error-processing; however, these differences were not consistent across tasks. Given the similar behavioral performance across the groups the observed differences in brain responses may not represent an advantage for bilinguals. The results are discussed with respect to previous findings.

Unique Effects of a Family Literacy Program on the Early Reading Development of English Language Learners

Research Findings: The present study evaluated the effects of a Family Literacy program on the early English reading development of speakers of English as a first language (EL1s) and English language learners (ELLs). The study included a linguistically and culturally diverse sample of 132 kindergarten children and their parents. Families in the experimental group participated in a 9-week intervention program that was designed to promote early literacy in the home, whereas those in the control group did not receive the intervention. Both the experimental and control groups included EL1 and ELL children. Dependent variables included children's gains in alphabet knowledge, conventions of print, and meaning. Results indicated that ELL children in the experimental group made greater gains in their knowledge of the alphabet and their ability to infer meaning from print than EL1 children in the experimental group and both ELL and EL1 controls. There were no language group differences in children's gains in conventions of print. Practice or Policy: The results suggest that Family Literacy programs are associated with differential effects on the English reading development of EL1 and ELL children. Educational implications related to the development and implementation of effective Family Literacy programs for diverse communities are discussed.

Health-related quality of life outcomes among cervical cancer survivors: Examining ethnic and linguistic differences

Background: This study aims to investigate the utility of an explanatory health-related quality of life (HRQOL) model for cervical cancer survivors. Specifically, this study focuses on the different patterns in the structural model of HRQOL by ethnic and language groups. Methods: Secondary data derived from 560 European- and Latina-American cervical cancer survivors was used. The study methodology was guided by the Contextual Model of health-related quality of life. Results: Structural equation modeling demonstrated significant differences in the overall structural models for HRQOL by ethnicity. For example, European-Americans showed significant association between radiation therapy and HRQOL, while life burden was related to sexual impact for Latina-Americans only. The results showed the significant mediating effects of general health status and psychological well-being between patient–doctor relationship and HRQOL, and between life burden and HRQOL, respectively, for all ethnic and language groups. While language group differences (limited English vs. English proficient) among Latina-Americans emerged in bivariate analyses; these distinctions were not upheld in the overall structural models. Conclusion: The unique contribution of the individual- and systemic-level components in predicting overall HRQOL outcome seems to vary by ethnic group membership. Our findings advance our understanding of the predictors and the association among the predictors of HRQOL. This study may contribute to the evolution of culturally and linguistically responsive HRQOL conceptual frameworks and instrumentation for vulnerable populations.

Parent involvement in early childhood: a comparison of English language learners and English first language families

This study evaluated parents’ communication, involvement and knowledge of their children’s abilities in reading and mathematics among parents who spoke English as a first language (EL1) and those who were English language learners (ELL). Forty‐two kindergarten‐aged children, their parents and their teachers participated in the study. Results indicated that EL1 parents communicated more frequently with the teacher than ELL parents. However, there were no language group differences in parents’ involvement in their children’s education (as rated by the teacher). For both groups of parents (EL1 and ELL), parents’ ratings of their children’s abilities in reading did not predict children’s reading scores. However, parents’ ratings of their children’s abilities in mathematics did predict their children’s mathematics scores. Further analyses indicated that this relationship was not mediated by parents’ communication or involvement. It is concluded that parents’ accurate knowledge of their children’s abilities in mathematics may be the result of their involvement at home and particularly for ELL parents, their greater understanding of and emphasis on mathematics learning.

Language and Early Reading among Children with Orofacial Clefts

To test the hypothesis that children with orofacial clefts score lower than controls on measures of language and reading and to examine predictors of these outcomes. Longitudinal study tracking the development of children with and without orofacial clefts from infancy through age 7 years. Children with isolated cleft lip and palate (n = 29) and cleft palate only (n = 28) were recruited from the craniofacial program in an urban medical center. Seventy-seven demographically similar, unaffected controls were recruited via advertisements placed in area pediatric clinics and community centers. Infant measures assessed child development and mother-child interactions during feeding and teaching tasks. At ages 5 and 7 years, measures of language functioning and academic achievement were completed along with an interview to collect school placement data and information on speech services received. There were no significant group differences in language at ages 5 and 7 years. Children with clefts scored significantly higher than controls on measures of early reading at age 7 years. Outcomes were predicted by demographic factors, the quality of mother-child interactions during teaching and feeding tasks, and cognitive development scores at age 24 months. Findings do not support the hypothesis that children with clefts score lower than controls on neurocognitive and academic achievement measures. Predictive analyses revealed several dimensions that may be used in clinical practice to identify children at risk for learning and developmental concerns.
