Spelling well despite developmental language disorder: what makes it possible?

The goal of the study was to investigate the overlap between developmental language disorder (DLD) and developmental dyslexia, identified through spelling difficulties (SD), in Russian-speaking children. In particular, we studied the role of phoneme awareness (PA), rapid automatized naming (RAN), pseudoword repetition (PWR), morphological (MA), and orthographic awareness (OA) in differentiating between children with DLD who have SD from children with DLD who are average spellers by comparing the two groups to each other, to typically developing children as well as children with SD but without spoken language deficits. One hundred forty-nine children, aged 10.40 to 14.00 years, participated in the study. The results indicated that the SD, DLD, and DLD/SD groups did not differ from each other on PA and RAN Letters and underperformed in comparison to the control groups. However, whereas the children with written language deficits (SD and DLD/SD groups) underperformed on RAN Objects and Digits, PWR, OA, and MA, the children with DLD and no SD performed similarly to the children from the control groups on these measures. In contrast, the two groups with spoken language deficits (DLD and DLD/SD) underperformed on RAN Colors in comparison to the control groups and the group of children with SD only. The results support the notion that those children with DLD who have unimpaired PWR and RAN skills are able to overcome their weaknesses in spoken language and PA and acquire basic literacy on a par with their age peers with typical language. We also argue that our findings support a multifactorial model of DLD.     

Spelling Performance in Children with Developmental Language Disorder: A Meta-Analysis across European Languages

ABSTRACT

Spelling difficulties often occur in children with developmental language disorder (DLD), the extent and drivers of these difficulties are underspecified. Meta-analyses were conducted to address this gap. We identified child-based factors (age, language spoken, profile of difficulties) and task-based factors (text production or dictation) as potential moderators of the impact of DLD on spelling performance. Thirty-two studies were analyzed, including 984 children with DLD. Large differences between the spelling of children with DLD and their age-matched peers were found. The average mean effect size was ?1.42, 95% confidence interval [?1.60, ?1.24]. Heterogeneity was large. Effect size estimates were larger when participants had additional phonological or reading difficulties than when they did not. No differences were found between participants with DLD and their language-matched peers. The results are discussed with respect to the underlying processes that impact on spelling across languages. Specific recommendations for future studies are made.     

Psychometric approaches to the identification of LD: IQ and achievement scores are not sufficient

Simulated data were used to demonstrate that groups formed by imposing cut-points based on either discrepancy or low-achievement definitions of learning disabilities (LD) are unstable over time. Similar problems were demonstrated in longitudinal data from the Connecticut Longitudinal Study, where 39% of the children designated as having LD in Grade 3 changed group placement with repeated testing in Grade 5. These results show that the practice of subdividing a normal distribution with arbitrary cut-points leads to instability in group membership. Approaches to the identification of children as having LD based solely on individual test scores not linked to specific behavioral criteria lead to invalid decisions about individual children. Low-achievement definitions are not a viable alternative to IQ-discrepancy definitions in the absence of other criteria, such as the traditional exclusions and response to quality intervention. If we accept the premise of multiple classes of low achievers, then we must develop identification systems that are valid and abandon systems whose only merits are their historical precedence and convenience.     

Utility of kindergarten teacher judgments in identifying early learning problems

Most existing research on early identification of learning difficulties has examined the validity of methods for predicting future academic problems. The present study focused instead on the sensitivity of kindergarten teachers to learning problems in their students and on the continuity of teacher-identified problems over time. To identify early learning problems, kindergarten teachers in a suburban school district rated student progress toward six academic objectives as satisfactory or unsatisfactory. Twenty percent of the district's 303 kindergarten children received unsatisfactory ratings in at least one area. Thirty-eight of these children (identified group) were matched to 34 children with satisfactory ratings in all areas (nonidentified group). Results of testing conducted during kindergarten revealed poorer academic achievement in identified children than in nonidentified children. Children from the identified group also performed more poorly than children from the nonidentified group on tests of phonological processing and working memory/executive function and were rated by teachers as having more behavior and attention problems and lower social competence. Follow-up of the sample to first grade documented continued learning problems in the identified group. These findings support the use of teacher judgements in early detection of learning problems and argue against reliance on discrepancy criteria.     

Diagnosis and treatment of reading disabilities based on the component model of reading: an alternative to the discrepancy model of LD

Currently, learning disabilities (LD) are diagnosed on the basis of the discrepancy between students' IQ and reading achievement scores. Students diagnosed with LD often receive remedial instruction in resource rooms. The available evidence suggests that the educational policy based on this discrepancy model has not yielded satisfactory results. This has led researchers to try other paradigms, such as the component model and response to intervention, for dealing with children with reading disabilities. The component model of reading (CMR) described in the present article identifies the reading component that is the source of reading difficulty and targets instruction at that component. Study 1 describes the CMR and reports on its validity. Study 2 describes the successful outcome of a 7-year CMR-based reading instruction program. Compared to the discrepancy model, the CMR has demonstrated several advantages.     

Does Inattention and Hyperactivity Moderate the Relation Between Speed of Processing and Language Skills?

The causal role of speed of processing (SOP) in developmental language disorder (DLD) is unclear given that SOP has been implicated in other neurodevelopmental disorders such as attention-deficit/hyperactivity disorder. This study investigated associations between SOP, language, and inattention/hyperactivity in a U.K. epidemiological cohort (N = 528). Monolingual children from a range of socioeconomic backgrounds were assessed longitudinally; at ages 5–6 (2012/2013) and 7–8 years (2014/2015). Persistent weaknesses in SOP characterized children with DLD but did not predict language longitudinally. Ratings of inattention/hyperactivity moderated the association between SOP and language, indicating that SOP deficits are particularly detrimental for language when coupled with poor attention/hyperactivity. SOP may be a shared risk factor for DLD and inattention/hyperactivity or a general marker of neurodevelopmental disorder.     

Developmental Outcomes for Children at High Risk of Dyslexia and Children With Developmental Language Disorder

We followed children at family risk of dyslexia and children with preschool language difficulties from age 3½, comparing them with controls (N = 234). At age 8, children were classified as having dyslexia or Developmental Language Disorder (DLD) and compared at earlier time points with controls. Children with dyslexia have specific difficulties with phonology and emergent reading skills in the preschool period, whereas children with DLD, with or without dyslexia, show a wider range of impairments including significant problems with executive and motor tasks. For children with both dyslexia and DLD, difficulties with phonology are generally more severe than those observed in children with dyslexia or DLD alone. Findings confirm that poor phonology is the major cognitive risk factor for dyslexia.     

Social Networks of Children With Developmental Language Disorder in Inclusive Preschool Programs

This study takes an ecological approach to examine how children with developmental language disorder (DLD) interact with their classmates within early childhood special education (ECSE) inclusive classrooms. Participants were 124 children with DLD, 56 children with other disabilities, and 247 typically developing children (M_age = 52.42 months, SD = 6.27) from 56 ECSE inclusive classrooms. Results of social network analysis showed that children with DLD had significantly smaller peer social networks and were more likely to be isolated. Children tended to interact with peers with the same DLD status. These effects of children's DLD status were above and beyond the effects of children's social pragmatics skills.     

A Comparison of Aggressive-Rejected and Nonaggressive-Rejected Children's Interpretations of Self-Directed and Other-Directed Rejection

The hypothesis that aggressive-rejected children are unaware of their social status because they are self-protective when processing negative peer feedback was tested in 3 studies. In Study 1, fourth-grade girls and boys were asked to name peers they liked or disliked, as well as peers they thought liked or disliked them. Comparisons of aggressive-rejected, nonaggressive-rejected, and average status groups revealed that aggressive-rejected children were more unrealistic in their assessments of their social status than were nonaggressive-rejected children. In Study 2, rejected and average boys identified in Study 1 were asked to name who they thought liked or disliked other children from their classroom. Comparisons of perceived and actual nominations for peers revealed that aggressive-rejected children were able to assess the social status of others as well as did nonaggressive-rejected and average status children. Because the difficulties aggressive-rejected children demonstrated in Study 1 did not generalize to judging the status of others in Study 2, the self-protective hypothesis was supported. Study 3 provided a parallel test of this hypothesis under more controlled conditions. Subjects from Study 2 viewed other children receiving rejection feedback from peers in videotaped interactions and received similar feedback themselves from experimental confederates. While all subjects rated self-directed feedback somewhat more positively than other-directed feedback, aggressive-rejected subjects had the largest self-favoring discrepancy between their judgments of self- and other-directed feedback. These findings also suggest that aggressive-rejected children may make self-protective "errors" when judging other children's negative feelings about them. Ethnicity differences in evaluating peer feedback emerged in Studies 1 and 3, raising questions about the impact of minority status on children's evaluations of rejection feedback.     

The behavioral and linguistic interactions of specifically language-delayed and normal boys with their mothers

3 studies were based on subgroups selected from larger pools of either normal children or children with delays in the expression and/or comprehension of language but normal nonverbal abilities. In Study 1, younger (28-50 months) and older (51-68 months) normal (N = 27) and language-delayed (N = 33) boys were observed interacting with their mothers in free play and structured task situations. Although language-delayed children initiated fewer interactions, their responsiveness to maternal interactions, questions, and commands did not differ from that of normal children. Mothers questioned language-delayed children less frequently during tasks but did not differ from mothers of normal children on other measures of interaction, responsiveness, control, or reward strategies. In Study 2, the complexity of maternal speech directed to normal (N = 11) and expressively delayed (N = 11) boys who were matched on the basis of comprehensive skills did not differ. Maternal speech to boys with delays in both language expression and comprehension (N = 11) was significantly less complex. In Study 3, the discrepancy between the speech complexity of mothers and that of their language-delayed children (N = 47) was greatest in younger children with greater expression and comprehension delays, who initiated fewer interactions and proved less responsive to maternal interactions and questions.     

An operational definition of learning disabilities (cognitive domain) using WISC full scale IQ and peabody individual achievement test scores

An operational index of discrepancy to assist in identifying learning disabilities (LD) in the cognitive domain was derived using the Full Scale IQ, Wechsler Intelligence Scale for Children (Wechsler, 1949, and relevant subtest scores on the Peabody Individual Achievement Test (PIAT) (Dunn and Markwardt, 1970. The index was applied to all legally identified LD children (N = 60) of a Michigan county who were in the LD program (1% of the total elementary school population of 6000 children). Of the 50 males and 10 females (mean age: 9 years 2 months; mean IQ: 91), the index identified 74% and 30% respectively as may be LD in the cognitive domain. This comprised 67% of the 60 children, or 2/3 of 1 % of the total elementary school population. Of the 67% may be LD children, 93% had discrepancy low PIAT subtest scores in Reading Recognition, 88% in Reading Comprehension, 83% in Spelling, and 52% in Arithmetic. Considerable caution should be exercised when classifying children, especially females, as LD.     

Pilot study of online training modules to improve speech-language pathology students’ explicit syntax knowledge

Children with developmental language disorder (DLD) exhibit weaknesses in the syntactic aspects of language that affect their spoken language (i.e., speaking and listening) and written language (i.e., reading and writing). Speech-language pathologists (SLP) who work with children with DLD are the team member with the greatest expertise in syntax. However, emerging data suggest that speech-language pathology (SLP) students and SLPs have limitations in their explicit syntax knowledge that may affect how they assess and treat the language and literacy knowledge and skills of children with DLD. Additionally, there is a lack of data on the outcomes of professional development specific to syntax. This paper reports on the effects of self-paced, online learning modules on SLP graduate students’ explicit syntax knowledge. Thirty-six SLP graduate students completed online syntax learning modules that taught four pairs of syntactic structures. SLP graduate students experienced a treatment effect from two of the four online training modules. Treatment effects seemed to be influenced by the syntactic skill being treated, by prior knowledge of that particular syntactic structure, and by other environmental factors, including training program. Although future studies should explore these factors further, the outcomes of this pilot study are the first to report on a way to improve SLP graduate students’, and potentially SLPs’, explicit syntax knowledge.

     

Acquisition of the Novel Name–Nameless Category (N3C) Principle

Toddlers' acquisition of the Novel Name–Nameless Category (N3C) principle was examined to investigate the developmental lexical principles framework and the applicability of the specificity hypothesis to relations involving lexical principles. In Study 1, we assessed the ability of 32 children between the ages of 16 and 20 months to use the N3C principle (operationally defined as the ability to fast map). As predicted, only some of the children could fast map. This finding provided evidence for a crucial tenet of the developmental lexical principles framewor: Some lexical principles are not available at the start of language acquisition. Children who had acquired the N3C principle also had significantly larger vocabularies and were significantly more likely to demonstrate 2-category exhaustive sorting abilities than children who had not acquired the principle. The 2 groups of children did not differ in either age or object permanence abilities. The 16 children who could not fast map were followed longitudinally until they attained a vocabulary spurt; at that time, their ability to fast map was retested (Study 2). Results provided a longitudinal replication of the findings of Study 1. Implications of these findings for both the developmental lexical principles framework and the specificity hypothesis are discussed.     

The validity of discrepancy-based definitions of reading disabilities.

This study addressed the validity of distinguishing children with reading disabilities according to the presence or absence of discrepancies between intelligence test scores and academic achievement. Three definitions of reading disability were used to provide criteria for five groups of children who (a) met a discrepancy-based definition uncorrected for the correlation of IQ and achievement; (b) met a discrepancy-based definition correcting for the correlation of IQ and achievement; (c) met a low achievement definition with no IQ discrepancy; (d) met criteria a and b; and (e) met none of the criteria and had no reading disability. Comparison of these five groups on a set of 10 neuropsychological tests corrected for correlations with IQ showed that group differences were small and accounted for little of the variability among groups. These results question the validity of segregating children with reading deficiencies according to discrepancies with IQ scores.     

Accelerating chronically unresponsive children to tier 3 instruction: what level of data is necessary to ensure selection accuracy?

Response-to-intervention (RTI) approaches to disability identification are meant to put an end to the so-called wait-to-fail requirement associated with IQ discrepancy. However, in an unfortunate irony, there is a group of children who wait to fail in RTI frameworks. That is, they must fail both general classroom instruction (Tier 1) and small-group intervention (Tier 2) before becoming eligible for the most intensive intervention (Tier 3). The purpose of this article was to determine how to predict accurately which at-risk children will be unresponsive to Tiers 1 and 2, thereby allowing unresponsive children to move directly from Tier 1 to Tier 3. As part of an efficacy study of a multitier RTI approach to prevention and identification of reading disabilities (RD), 129 first-grade children who were unresponsive to classroom reading instruction were randomly assigned to 14 weeks of small-group, Tier 2 intervention. Nonresponders to this instruction (n = 33) were identified using local norms on first-grade word identification fluency growth linked to a distal outcome of RD at the end of second grade. Logistic regression models were used to predict membership in responder and nonresponder groups. Predictors were entered as blocks of data from least to most difficult to obtain: universal screening data, Tier 1 response data, norm referenced tests, and Tier 2 response data. Tier 2 response data were not necessary to classify students as responders and nonresponders to Tier 2 instruction, suggesting that some children can be accurately identified as eligible for Tier 3 intervention using only Tier 1 data, thereby avoiding prolonged periods of failure to instruction.     

Development and initial validation of a scale to measure emotional abuse among school children aged 13-15 years in Sri Lanka

OBJECTIVE: To develop a scale to measure emotional abuse among school children aged 13-15 years in Sri Lanka that can be used in field settings. METHOD: Emotional abuse was defined based on available literature. Review of literature and discussions with a panel identified 85 items indicating abusive behaviors. Content validity and social acceptability were achieved by getting the views of this same panel and parents, respectively. Item analysis and assessment of validity were carried out based on the responses to the draft instrument by 105 children aged 13-15 years attending a school in an urban slum area. The test-retest reliability of the scale was assessed using the responses from 144 students from a different school. Criterion validity was established by comparing the independent assessments of a psychiatrist for the presence or absence of emotional abuse with the respective scores of the children on the scale. RESULTS: The scale developed to assess emotional abuse included 46 items having a Cronbach alpha of .89. The test-retest reliability was .73. A cutoff score of 95 was identified at a sensitivity of 76.9% and a specificity of 51.4%. CONCLUSIONS: A scale that had a satisfactory level of reliability and validity was socially acceptable, which could be used in school settings in Sri Lanka was developed to enable identification of emotional abuse among school children aged 13-15.     

Language maintenance and loss in a population study of young Australian children

Information about children's cultural and linguistic diversity and language acquisition patterns is important for the development of sustainable educational practices. While there is some knowledge about language maintenance and loss in adults and older children, there is limited information about young children. The first three waves of data from the Longitudinal Study of Australian Children (LSAC), involving 4252 young children, were considered longitudinally over the first five years of life to identify patterns of language maintenance and loss among those who speak languages other than English. The most common languages other than English spoken by the children were Arabic, Vietnamese, Italian, Spanish, and Greek and 9.1% of all children were reported to use a language other than English at wave 1, 15.7% at wave 2, and 15.2% at wave 3. Overall, 91.5% of children maintained speaking a language other than English between wave 1 and wave 2, and 86.6% did so between wave 1 and wave 3. Children's patterns of language acquisition and loss over the first five years of life varied within and between language groups. For example, Arabic-speaking children tended to maintain Arabic throughout early childhood, whereas Italian-speaking children's use of Italian decreased over the first five years of life while use of English steadily increased. Environmental and personal factors such as parental language use, presence of a grandparent in the home, type of early childhood care, first- and second-generation immigrant status, and parental perception of support from the educational environment were related to language maintenance among non-English speaking children.     

The Dimensionality of Language Ability in Four-Year-Olds: Construct Validation of a Language Screening Tool

The Norwegian government recommends a systematic language assessment of all four-year-olds as part of the general health surveillance program for the purpose of identifying children at risk of language delay. This study aimed to investigate the construct validity of the recommended language screening tool called LANGUAGE4 [SPRÅK4] by first examining the dimensionality of the underlying construct of the tool, after which the concurrent convergent validity was established by regressing an external language factor, defined by four standardized language tests, on a single higher-order factor. The findings provide support for a higher-order model with one general language factor, suggesting that a large amount of the variance in LANGUAGE4 is attributable to a single common factor at the second-order level. Furthermore, this single factor explained a considerable amount of the variance in the external language factor. Our findings are interpreted as support for satisfactory construct validity of LANGUAGE4.     

Children's judgments of disloyal and immoral peer behavior: subjective group dynamics in minimal intergroup contexts

The developmental model of subjective group dynamics hypothesizes that peer exclusion during middle childhood involves inferences about group dynamics. To test the generality of this prediction, children judged, within minimal groups, peers whose behavior was loyal versus disloyal (Study 1: n = 46, mean age = 113 months) or morally acceptable versus unacceptable (Study 2: n = 121, mean age = 90 months). As hypothesized, in Study 1, children used their understanding of loyalty norms as a basis for evaluating peers. In both studies, higher commitment to the in-group increased use of group-based criteria for judging peers. In Study 2, children employed moral- and group-based criteria independently for judging peers. Multiple classification skill was associated with lower intergroup bias and greater use of morality-based judgment.     

Social contexts of learning literate language: The role of varied, familiar, and close peer relationships

Two prominent theories in evolutionary biology have stressed the role of social contexts in the evolution of primate cognition. One theory holds that cognition evolved in the context of individuals having to keep track of their interactions with a variety of conspecifics. In the other theory, cognition evolved in the contexts of familiar and close social relationships. In this paper, we present two experiments examining the effects of varied, familiar, and close social contacts on preschool children's literate language and story re-reading. We hypothesized, based on developmental evolutionary theory, that closeness, in the form of increased familiarity and friendship, would maximize children's expression of emotional terms, conflict/resolution cycles, collaborative responses, literate language, and story re-readings. In Study 1, children were exposed to one of two conditions. In the more familiar condition, initially unfamiliar children interacted with the same peer across four separate observations. In the less familiar, varied condition, a focal child interacted with a different unfamiliar peer on four separate occasions. Consistent with predictions, children in the more familiar condition increased their use of emotional terms and literate language and story re-reading with time. In Study 2, a familiar group (as defined in Study 1) was compared with children in bestfriend dyads. As predicted, friends outperformed familiar peers initially, but between-group differences decreased across time while children's performance in the familiar group increased across time. Results are discussed in terms of the role of familiarity in the evolution of cooperation and cognition.
