아랍어 학습자의 수용적 및 생산적 어휘 지식 크기와 어휘학습전략의 관계 연구

This research explores the relationship between vocabulary learning strategy and receptive and productive vocabulary knowledge size to examine more effective Arabic learning methods. In order to ask research questions, a questionnaire survey was conducted on 30 Arabic learners (First Year, 2nd Semester) in Hankuk University of Foreign Studies on receptive and productive vocabulary knowledge tests and vocabulary learning strategies. The results are as follows.
 First, receptive knowledge size is bigger than productive knowledge size, and there is a positive relationship between the two. Second, receptive and productive knowledge size turned out to be related to the all subcategories of vocabulary learning strategies. Accordingly, the bigger the receptive and productive knowledge size, the more diverse vocabulary learning strategies were being used. Third, the students whose receptive vocabulary knowledge size was big used all available vocabulary learning strategies compared to those with low receptive vocabulary knowledge size. The students with big vocabulary knowledge size showed differences in five subcategories of vocabulary learning, excluding social strategy under meaning discovery. Fourth, the learning group with big differences in receptive and productive vocabulary knowledge size, showed differences in five vocabulary learning strategies compared to the group with big size except for social strategies in meaning discovery strategies.

Age at first exposure to antibiotics and neurodevelopmental outcomes in childhood

RationaleViral illnesses in children are common and are frequently treated with antibiotic medication. Antibiotics reduce the diversity and composition of the gut microbiota, leading to poor developmental outcomes.ObjectivesTo investigate the relationship between age at first exposure to antibiotics and cognitive and behavioural development at 4.5 years while controlling for multiple confounders, including otitis media.MethodsStudy participants were 5589 children enrolled in the broadly generalisable Growing Up in New Zealand cohort study, with antibiotic exposure data, maternal antenatal information, and age 4.5-year behaviour and cognitive outcome data. Children were categorised as first exposed to antibiotics according to the following mutually exclusive ages: 0–2 months; 3–5 months; 6–8 months; 9–11 months; 12–54 months or not exposed by 54 months. Developmental outcome measures included the Strengths and Difficulties Questionnaire, Luria hand clap task, and the Peabody Picture Vocabulary Test-III.ResultsIn univariate analysis, there was an evident dose–response relationship where earlier exposure to antibiotics in the first year of life was associated with behavioural difficulties, lower executive function scores, and lower receptive language ability. After adjusting for confounders, pairwise comparisons showed that first antibiotic exposure between birth and 3 months or between 6 and 9 months was associated with lower receptive vocabulary. Antibiotic exposure at any age prior to 12 months was associated with increases in behavioural difficulties scores at 4.5 years.ConclusionsFollowing adjustment for socioeconomic factors and otitis media, there is evidence that antibiotic exposure during potentially sensitive windows of development is associated with receptive language and behaviour later in childhood.

Influência do ambiente familiar, percepção parental e nível econômico no vocabulário receptivo de crianças

ABSTRACT Purpose: to examine the influence of familial environment, parental perception, and socioeconomic conditions on the receptive vocabulary of elementary school children. Methods: an analytical cross-sectional observational study. The students were selected by stratified proportional sampling, using the Receptive Vocabulary Test. Those responsible for the children answered the anamnesis and the inventory of family environmental resources. Initially, a bivariate analysis was performed using the chi-square test, considering p<0.20. In the multivariate analysis of binary logistic regression, p<0.05 was considered, and the quality of the model was evaluated through the Hosmer-Lemeshow method. Results: out of the 263 students, 131 were males, 142 were in the third grade and were on average 7.6 years old (±0.57), and 111 had a low receptive vocabulary. In the bivariate analysis, there was a relationship between parental perception about learning to read and write, school failure, and the outcome (p<0.05). The variables environment, resources, and stability of family life were also used for multivariate analysis (p<0.20). Conclusion: Parental perception of difficulty in reading and writing and a lack of family stability were factors associated with poor receptive vocabulary.

Variation in Auditory Experience Affects Language and Executive Function Skills in Children Who Are Hard of Hearing.

Children who are hard of hearing (CHH) experience delays in spoken language and executive function, but the mechanisms for these deficits remain unresolved. Differences in auditory experience and language skills have been examined as contributing factors to deficits in executive function, primarily with children who are deaf and children with cochlear implants. The theoretical model of cumulative auditory experience quantifies auditory dosage as how much speech is audible and how often children wear their hearing aids. CHH with higher auditory dosage have better language outcomes than peers with less auditory dosage. However, the effects of auditory experience on executive function have not been studied in CHH. The goal of this study was to examine the influences of auditory experience and language skills on the development of executive function in CHH. We collected measures of aided speech audibility, hearing aid use, executive function, and receptive vocabulary in 177 CHH and 86 children with typical hearing who were 5- to 10 years old and matched for socioeconomic status and nonverbal intelligence. Auditory dosage was calculated by combining each child's average hours of hearing aid use with their audibility for speech to create a variable that quantifies individual differences in auditory access. CHH had lower receptive vocabulary and deficits in executive function related to working memory and selective attention compared to peers with typical hearing. CHH with greater auditory dosage had higher receptive vocabulary than CHH with lower auditory dosage. Better receptive vocabulary was associated with better scores on executive function measures related to working memory and attention. Auditory dosage was also directly associated with measures of verbal working memory. CHH have deficits in language and some, but not all, areas of executive function related to working memory and attention. Auditory dosage was associated with language abilities and verbal working memory. Language was associated with individual differences in executive function skills related to attention and working memory. These results provide support for systems theories regarding the development of executive function in CHH. Interventions that improve auditory access and language may be effective for improving executive function related to working memory and attention in CHH.

Effects of Spanish vocabulary knowledge on the English word knowledge and listening comprehension of bilingual students

ABSTRACT The purpose of the current study was to examine the influence of L1 (i.e. Spanish) receptive vocabulary on both expressive and receptive knowledge of target vocabulary words taught through L2 (i.e. English) instruction and intervention. Participants were Bilingual US kindergarten students determined to be at-risk based on English receptive vocabulary. To determine student vocabulary level in Spanish, we administered a receptive Spanish vocabulary assessment. Students were grouped into matched clusters within classrooms. Clusters were randomly assigned to receive whole group vocabulary instruction only in L2 (i.e. the control group, n = 172) or whole group plus small group vocabulary instruction in L2 (i.e. the treatment group, n = 179). Findings indicated that bilingual students with high receptive vocabulary knowledge in Spanish significantly outperformed bilingual students with low receptive vocabulary knowledge in Spanish. Effects of Spanish vocabulary knowledge were maintained one year later, at the end of first grade, as measured by a researcher developed expressive vocabulary measure in English. We did not find an interaction effect between condition and student level of Spanish receptive vocabulary. Implications for research and practice are discussed.

Frequencies of Behavioral Problems Reported by Parents and Teachers of Hearing-Impaired Children With Cochlear Implants.

Background: Internalizing and externalizing behavioral problems were frequently reported in profoundly hearing-impaired (HI) children with hearing aids. Due to the positive effect of cochlear implants (CIs) on hearing and language development, a positive effect on behavioral problems was expected. However, there is no consensus about the frequency of behavioral problems in CI children, and studies are often based on one informant with the risk of missing behavioral problems in other contexts.Aims: The first aim of this study was to investigate the frequency of behavioral problems in children with CIs as compared to a hearing normative sample. The second aim was to measure the agreement between the parents’ and teachers’ rates on the behavioral problem scales. And the third aim was to investigate the relation between speech perception, language skills and the frequencies of reported behavioral problems.Methods: Of 71 CI children, 51% were girls and 49% were boys, and the mean age was 8.6 (SD = 3.3). Behavior was reported by parents using the Child Behavior Checklist (CBCL) and by teachers using the Teacher Report Form (TRF). Frequencies of behavioral problems of CI children (6–16 years) were compared to a normative sample with the chi square test. Parent-teacher agreement was measured with the intraclass correlation coefficient (ICC 2,1). Next CI children were divided into four ability level categories regarding speech perception and language skills. Frequencies of behavioral problems were compared between the categories with the chi square test.Results: Parents and teachers of CI children reported similar frequencies of behavioral problems to the normative sample. Fair to low parent-teacher agreements were found on the behavioral problem scales. A significantly higher frequency of behavioral problems was reported in children with low speech perception and receptive vocabulary at school.Conclusion: Parents and teachers report similar frequencies of behavioral problems children with CIs compared to a hearing normative sample. Children with lower speech perception and language levels are more at risk of developing behavioral problems at school. Adequate speech perception and language levels are found to be protective factors for the development of behavior.

Differences in the relation between temperament and vocabulary based on children’s stuttering trajectories

PurposeThe purpose of this study was to assess the relation between temperament and vocabulary development for children who stutter and persist, children who stutter and recover and children who do not stutter. MethodsParticipants, aged 3;0–4;11 at the start of the study, were followed for two years. They were classified as persisting (n = 10), recovered (n = 26), and non-stuttering (n = 24) based on multiple assessments of stuttering spaced across study participation. Groups were balanced for age and gender ratios. At each visit, participants completed the Peabody Picture Vocabulary Test, 4th edition, and the Expressive Vocabulary Test, 2nd edition; caregivers completed the Children’s Behavior Questionnaire. ResultsFor both persisting and recovered groups, higher negative emotionality was associated with lower receptive vocabulary. These associations were both significantly more negative than the non-stuttering group’s association. ConclusionThese findings suggest that receptive vocabulary development is differentially linked to temperament based on a child’s stuttering status. As others have speculated (Conture & Walden, 2012), it appears as though there are salient associations between temperament, speech-language development, and childhood stuttering.

Language abilities of Indigenous and non-Indigenous Australian children from low socioeconomic backgrounds in their first year of school

Purpose: Concern exists about the cross-cultural appropriateness of existing language assessments for non-mainstream populations, including Indigenous children who may speak a non-standard dialect of the mainstream language. This study therefore aims to investigate the language skills of Indigenous Australian children in comparison with non-Indigenous children, with a view to exploring the cultural appropriateness of language sampling assessment methods.Method: The performance of 51 typically developing Indigenous and non-Indigenous Australian children was compared on a standardised assessment and a spoken narrative protocol using language sample analysis measures. All children were in their first year of school and from the same regional city.Result: While the Indigenous children attained significantly lower receptive vocabulary scores than the non-Indigenous children, most language sampling measures from the spoken narrative protocol were similar across the two groups of children.Conclusion: Flexible, naturalistic language sampling approaches using a spoken narrative protocol are thus recommended for Indigenous children from the under-researched Australian context. However, normative data for language sampling are lacking, and further research is needed to explore the cultural validity of assessment and diagnostic procedures for Indigenous Australian children, as well as the influence of socioeconomic and family factors on language skills.

Home Language Will Not Take Care of Itself: Vocabulary Knowledge in Trilingual Children in the United Kingdom.

Language input is crucial for language acquisition and especially for children’s vocabulary size. Bilingual children receive reduced input in each of their languages, compared to monolinguals, and are reported to have smaller vocabularies, at least in one of their languages. Vocabulary acquisition in trilingual children has been largely understudied; only a few case studies have been published so far. Moreover, trilingual language acquisition in children has been rarely contrasted with language outcomes of bilingual and monolingual peers. We present a comparison of trilingual, bilingual, and monolingual children (total of 56 participants, aged 4;5–6;7, matched one-to-one for age, gender, and non-verbal IQ) in regard to their receptive and expressive vocabulary (measured by standardized tests), and relative frequency of input in each language (measured by parental report). The monolingual children were speakers of Polish or English, while the bilinguals and trilinguals were migrant children living in the United Kingdom, speaking English as a majority language and Polish as a home language. The trilinguals had another (third) language at home. For the majority language, English, no differences were found across the three groups, either in the receptive or productive vocabulary. The groups differed, however, in their performance in Polish, the home language. The trilinguals had lower receptive vocabulary than the monolinguals, and lower productive vocabulary compared to the monolinguals. The trilinguals showed similar lexical knowledge to the bilinguals. The bilinguals demonstrated lower scores than the monolinguals, but only in productive vocabulary. The data on reported language input show that input in English in bilingual and trilingual groups is similar, but the bilinguals outscore the trilinguals in relative frequency of Polish input. Overall, the results suggest that in the majority language, multilingual children may develop lexical skills similar to those of their monolingual peers. However, their minority language is weaker: the trilinguals scored lower than the Polish monolinguals on both receptive and expressive vocabulary tests, and the bilinguals showed reduced expressive knowledge but leveled out with the Polish monolinguals on receptive vocabulary. The results should encourage parents of migrant children to support home language(s), if the languages are to be retained in a longer perspective.

Baseline Performance and Psychometric Properties of the Child Sport Concussion Assessment Tool 3 (Child-SCAT3) in 5- to 13-year-old Athletes.

To determine the normative, baseline performance and psychometric properties of the Child Sport Concussion Assessment Tool 3 (Child-SCAT3) in 5- to 13-year-old athletes. Cross-sectional study. Practice fields. Contact sport athletes (N = 155) 5 to 13 years old. Age, gender, verbal intellectual functioning (receptive vocabulary). Child-SCAT3: self-reported and parent-reported symptoms, cognitive performance (child form of the Standardized Assessment of Concussion; SAC-C), and balance (modified Balance Error Scoring System, mBESS-C; tandem gait). A subset of the sample repeated the Child-SCAT3 at another date. Some subjects also completed the Adult-SCAT3 version of the symptom checklist and mBESS. Small-to-medium-sized effects of age were observed on all Child-SCAT3 components. Effects of gender and receptive vocabulary were observed on select components of the SCAT3. Younger age and lower receptive vocabulary were independently associated with greater symptom endorsement, yet parents rated higher symptom burden for older children. Internal consistency reliability and stability of symptom ratings was good to excellent. Stability was more modest for SAC-C and tandem gait scores and very poor for mBESS-C scores, perhaps due to restricted variance. Inter-rater reliability (self-rated vs parent-rated symptoms) was fair. The Child-SCAT3 self-report symptom checklist may be inappropriate to administer to younger school-aged children. Some of the age effects observed warrant use of demographically appropriate norms in Child-SCAT3 interpretation. The findings can provide guidance for clinicians assessing children of varying ages and point to directions for further development of refined approaches for pediatric concussion assessment.

Patterns of Multiple Risk Exposures for Low Receptive Vocabulary Growth 4-8 Years in the Longitudinal Study of Australian Children.

Risk exposures and predictions of child development outcomes typically estimate the independent effects of individual exposures. As a rule though, children are not exposed piecemeal to individual or single risks but, rather, they are exposed to clusters of risk. Many of these clusters of risks are better thought of as comprising a developmental “circumstance” with a substantial duration, over which period, additional risk exposures also accumulate. In this paper we examined the distribution of 16 single risk exposures for low language ability using latent class analysis across a sample of approximately 4000 children from the Longitudinal Study of Australian Children. The best fitting model identified six distinct classes. 46% of children were in a Developmentally Enabled group, 20% were in a group typified as Working Poor families, 10% of children were in group typified as Overwhelmed group, 9% of children were in a group defined by Child Developmental Delay, 8% of children were in a group defined by Low Human Capital, and 7% of children were in a group defined by Resource Poor non-English Speaking background families. These groups had quantitatively and qualitatively distinct patterns of risk factors and showed different onward trajectories of receptive vocabulary. Our results demonstrate a range of multiple risk profiles in a population-representative sample of Australian children and highlight the mix of risk factors faced by children. Children with distinct patterns of risk factors have different onward trajectories of receptive vocabulary development.

Peer acceptance and the development of emotional and behavioural problems

Difficulties in peer acceptance during elementary school have been associated with emotional and behavioural problems. This study used a randomized controlled intervention design to test whether improvements in peer acceptance mediated reduced rates of emotional and behavioural problems in intervention compared to control-group children. A total of 615 elementary school children in the Netherlands were followed annually from kindergarten through second grade. Intervention children showed reductions in emotional and behavioural problems, and improved peer acceptance compared to controls. Improved peer acceptance mediated reductions in emotional and behavioural problem development. However, this mediation pathway held only for boys with low receptive vocabulary skills. These results indicate poor peer acceptance as a common underlying factor in emotional and behavioural problem development, particularly for children who are at risk for developing problems.

Risk factors for low receptive vocabulary abilities in the preschool and early school years in the longitudinal study of Australian children.

Receptive vocabulary development is a component of the human language system that emerges in the first year of life and is characterised by onward expansion throughout life. Beginning in infancy, children's receptive vocabulary knowledge builds the foundation for oral language and reading skills. The foundations for success at school are built early, hence the public health policy focus on reducing developmental inequalities before children start formal school. The underlying assumption is that children's development is stable, and therefore predictable, over time. This study investigated this assumption in relation to children's receptive vocabulary ability. We investigated the extent to which low receptive vocabulary ability at 4 years was associated with low receptive vocabulary ability at 8 years, and the predictive utility of a multivariate model that included child, maternal and family risk factors measured at 4 years. The study sample comprised 3,847 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Multivariate logistic regression was used to investigate risks for low receptive vocabulary ability from 4–8 years and sensitivity-specificity analysis was used to examine the predictive utility of the multivariate model. In the multivariate model, substantial risk factors for receptive vocabulary delay from 4–8 years, in order of descending magnitude, were low receptive vocabulary ability at 4 years, low maternal education, and low school readiness. Moderate risk factors, in order of descending magnitude, were low maternal parenting consistency, socio-economic area disadvantage, low temperamental persistence, and NESB status. The following risk factors were not significant: One or more siblings, low family income, not reading to the child, high maternal work hours, and Aboriginal or Torres Strait Islander ethnicity. The results of the sensitivity-specificity analysis showed that a well-fitted multivariate model featuring risks of substantive magnitude does not do particularly well in predicting low receptive vocabulary ability from 4–8 years.

Risk factors for children's receptive vocabulary development from four to eight years in the longitudinal study of Australian children.

Receptive vocabulary develops rapidly in early childhood and builds the foundation for language acquisition and literacy. Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk factor for under-achievement at school. In this study, bivariate and multivariate growth curve modelling was used to estimate trajectories of receptive vocabulary development in relation to a wide range of candidate child, maternal and family level influences on receptive vocabulary development from 4–8 years. The study sample comprised 4332 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Predictors were modeled as risk variables with the lowest level of risk as the reference category. In the multivariate model, risks for receptive vocabulary delay at 4 years, in order of magnitude, were: Maternal Non- English Speaking Background (NESB), low school readiness, child not read to at home, four or more siblings, low family income, low birthweight, low maternal education, maternal mental health distress, low maternal parenting consistency, and high child temperament reactivity. None of these risks were associated with a lower rate of growth from 4–8 years. Instead, maternal NESB, low school readiness and maternal mental health distress were associated with a higher rate of growth, although not sufficient to close the receptive vocabulary gap for children with and without these risks at 8 years. Socio-economic area disadvantage, was not a risk for low receptive vocabulary ability at 4 years but was the only risk associated with a lower rate of growth in receptive vocabulary ability. At 8 years, the gap between children with and without socio-economic area disadvantage was equivalent to eight months of receptive vocabulary growth. These results are consistent with other studies that have shown that social gradients in children's developmental outcomes increase over time.

Maternal Depression, Family Functioning and Children's Longitudinal Development

Analysis of data from the Canadian National Longitudinal Survey of Children and Youth reveals that 6% of children are born to mothers who experienced symptoms of depression during their first 2 years of life. The prevalence rises steadily until children are 10 years of age when it reaches 9%, and thereafter remains relatively stable. Children of depressed mothers are at increased risk of having low receptive vocabulary and displaying inattention or physical aggression at ages 4 to 5 years, only partially attributable to family demographic factors, family functioning and parenting qualities. Maternal depression occurring when the child was 2 to 3 years of age, was a risk factor for anxiety in 10 and 11 year olds. Timing or duration of maternal depression had no effect on math achievement. The risk of poor child outcome was greatest for mothers who experienced depression continuously or when their child was 2 to 3 years or older. Nurses need to assess and intervene to reduce the impact of depression on mothers and their children's development, well beyond the postpartum period.

Risk and Protective Factors Associated With Speech and Language Impairment in a Nationally Representative Sample of 4- to 5-Year-Old Children

To determine risk and protective factors for speech and language impairment in early childhood. Data are presented for a nationally representative sample of 4,983 children participating in the Longitudinal Study of Australian Children (described in McLeod & Harrison, 2009). Thirty-one child, parent, family, and community factors previously reported as being predictors of speech and language impairment were tested as predictors of (a) parent-rated expressive speech/language concern and (b) receptive language concern, (c) use of speech-language pathology services, and (d) low receptive vocabulary. Bivariate logistic regression analyses confirmed 29 of the identified factors. However, when tested concurrently with other predictors in multivariate analyses, only 19 remained significant: 9 for 2-4 outcomes and 10 for 1 outcome. Consistent risk factors were being male, having ongoing hearing problems, and having a more reactive temperament. Protective factors were having a more persistent and sociable temperament and higher levels of maternal well-being. Results differed by outcome for having an older sibling, parents speaking a language other than English, and parental support for children's learning at home. Identification of children requiring speech and language assessment requires consideration of the context of family life as well as biological and psychosocial factors intrinsic to the child.

Language performance of stuttering and nonstuttering children

This study investigated the syntactic and semantic language performance of typically dysfluent nonstuttering children, stuttering children, and highly dysfluent nonstuttering children. The three groups of children did not differ on Developmental Sentence Analysis scores. The stuttering and highly dysfluent nonstuttering children obtained significantly lower receptive vocabulary scores, made significantly more grammatical errors, and obtained significantly higher incorrect response scores on the semantic tasks.
