Is There a Cognate Effect in Bilingual Children With Developmental Language Disorder?

Expressive Vocabulary ◽

Test Items

Purpose: Cognates, words in two languages that share form and meaning, can be used to support vocabulary development in bilingual children. Typically developing bilinguals have shown better performance on cognates versus noncognates. Of key interest is whether bilinguals with developmental language disorder (DLD) also show a cognate effect and, if so, which factors are related to their cognate performance. Method: Thirty-five Spanish–English bilingual children (5–11 years old) with DLD completed the Expressive and Receptive One-Word Picture Vocabulary Tests, third edition, in English (EOW, ROW) to measure cognate performance. Test items were divided by difficulty level (easy, medium, and hard) and classified as cognates or noncognates using the Cross-Linguistic Overlap Scale for Phonology. Results: On average, children showed clear and robust cognate effects on EOW across difficulty levels with medium-to-large effect sizes. Results on the ROW showed minimal effects that varied by difficulty. Individually, 80% of participants (28 of 35) demonstrated a cognate effect in EOW, whereas only 31% (11 of 35) showed an effect in ROW. A cognate effect in ROW was positively correlated with age and English proficiency, whereas no factors correlated with the EOW cognate effect. Conclusions: Bilingual children with DLD show higher performance on cognates than noncognates, at least in expressive vocabulary. Participants who did show a receptive cognate effect tended to be older and have higher English proficiency. Further investigation is needed to identify factors underlying cognate performance in order to tailor intervention strategies that promote bilingual vocabulary development.

Hyperactivity Disorder

Purpose This study examined the influences of bilingualism and developmental language disorder (DLD) on nonverbal processing speed. DLD is associated with slower processing speed, but the extent to which slowing extends to bilingual populations is not established. The possible presence of bilingual cognitive effects could also lead to faster processing speed among bilingual children. Method Participants included 108 children of ages 6–8 years, including 56 Spanish–English bilinguals (29 with DLD and 27 with typical development) and 52 English-only monolinguals (25 with DLD and 27 with typical development). Language testing (in both languages for bilingual children) was combined with parent and school report to classify children as having DLD or typical language development. Children with attention-deficit/hyperactivity disorder were excluded from the sample. Reaction time from a choice visual detection task was used to index nonverbal processing speed. Results Children with DLD demonstrated slower processing speed than their typically developing peers, whereas bilingual children demonstrated faster processing speed than monolinguals. The effects of DLD and bilingualism did not interact. Conclusions This study replicates prior findings of slowed processing speed among children with DLD in both monolingual and bilingual children. Evidence of faster processing speed among bilingual children contributes to the complex literature surrounding the circumstances of bilingual cognitive effects.

Purpose Using a blocked cyclic picture-naming task, we compared accuracy and error patterns across languages for Spanish–English bilingual children with and without developmental language disorder (DLD). Method Pictured stimuli were manipulated for semantic similarity across two (Same and Mixed) category contexts. Children's productions were scored off-line for accuracy, error frequency, and error type. Results Typically developing children were more accurate and produced fewer errors than their peers with DLD; however, this was moderated by task language and semantic context. Children were generally more accurate when naming pictures in English compared to Spanish and in the Mixed-category context compared to the Same-category context. Analyses of error types further showed that children with less English language exposure specifically produced more nonresponses in English than in Spanish. Children with DLD produced more of each error type than their typically developing peers, particularly in Spanish. Conclusions Regardless of language ability, bilingual children demonstrated greater difficulty with lexical retrieval for pictured items in the semantically related context than in the unrelated context. However, bilingual children with DLD produced more errors of all types than is typical for children developing more than one language. Their greater error rates are not secondary to limited second language exposure but instead reflect deficits inherent to the nature of language impairment. Results from this study are discussed using a framework of semantic constraint, where we propose that because bilingual children with DLD have impoverished semantic networks, and this knowledge insufficiently constrains activation for lexical selection, thereby increasing error production.

Language Measures

Sentence repetition (SR) tasks have been shown to be excellent indicators of Developmental Language Disorder (DLD). However, there is still no consensus about which core ability they measure: language vs. Verbal Short-Term Memory (VSTM) and Verbal Working Memory (WM). Moreover, very few studies have investigated whether variables predicting SR performance differ in children with DLD compared to typically developing (TD) children, especially concerning bilingual children. This article reports on an SR study of 76 5- to 8-year-old bilingual children with ( n = 23) and without ( n = 53) DLD. The Bi-DLD group displayed significantly lower scores than the Bi-TD group on SR and on VSTM and WM measures. Regression analyses showed that SR was mainly linked to WM in the Bi-DLD group, but not in the TD group, where SR was mainly linked to (independent) language measures. This suggests that children with DLD, who have deficient linguistic knowledge, may rely more on their general processing ability (i.e. WM) in contrast to Bi-TD children, whose language skills are normal, and thus can be solicited for SR. Moreover, individual results suggested that performance on SR does not depend on minimal VSTM or WM spans.

Purpose This study examined the performance of Gulf Arabic–speaking children with developmental language disorder (DLD) on a Gulf Arabic nonword repetition (GA-NWR) test and compared it to their age- and language-matched groups. We also investigated the role of syllable length, wordlikeness, and phonological complexity in light of NWR theories. Method A new GA-NWR test was conducted with three groups of Gulf Arabic–speaking children: school-age children with DLD, language-matched controls (LCs), and age-matched controls (ACs). The test consisted of two- and three-syllable words that either had no clusters, medial clusters, final clusters, or medial + final clusters. Results The GA-NWR distinguished between the performance of children with DLD and the LC and AC groups. Results showed significant syllable length, wordlikeness, and phonological complexity effects. Differences between the DLD and typically developing groups were seen in two- and three-syllable nonwords; however, when compared on nonwords with no clusters, children with DLD were not significantly different from the LC group. Conclusions The GA-NWR test differentiated between children with DLD and their ACs and LCs. Findings, therefore, support its clinical utility in this variety of Arabic. Results showed that phonological processing factors, such as phonological complexity, may have stronger effects when compared to syllable length effects.

The Impact

Purpose Many children with developmental language disorder (DLD) have weaknesses in executive functioning (EF), specifically in tasks testing interference control and working memory. It is unknown how EF develops in children with DLD, if EF abilities are related to DLD severity and persistence, and if EF weaknesses expand to selective attention. This study aimed to address these gaps. Method Data from 78 children with DLD and 39 typically developing (TD) children were collected at three times with 1-year intervals. At Time 1, the children were 5 or 6 years old. Flanker, Dot Matrix, and Sky Search tasks tested interference control, visuospatial working memory, and selective attention, respectively. DLD severity was based on children's language ability. DLD persistence was based on stability of the DLD diagnosis. Results Performance on all tasks improved in both groups. TD children outperformed children with DLD on interference control. No differences were found for visuospatial working memory and selective attention. An interference control gap between the DLD and TD groups emerged between Time 1 and Time 2. Severity and persistence of DLD were related to interference control and working memory; the impact on working memory was stronger. Selective attention was unrelated to DLD severity and persistence. Conclusions Age and DLD severity and persistence determine whether or not children with DLD show EF weaknesses. Interference control is most clearly impaired in children with DLD who are 6 years and older. Visuospatial working memory is impaired in children with severe and persistent DLD. Selective attention is spared.

Purpose The aim of the study was to explore the potential of performance on a Danish sentence repetition (SR) task—including specific morphological and syntactic properties—to identify difficulties in children with developmental language disorder (DLD) relative to typically developing (TD) children. Furthermore, the potential of the task as a clinical marker for Danish DLD was explored. Method SR performance of children with DLD aged 5;10–14;1 (years;months; n = 27) and TD children aged 5;3–13;4 ( n = 87) was investigated. Results Compared to TD same-age peers, children with DLD were less likely to repeat the sentences accurately but more likely to make ungrammatical errors with respect to verb inflection and use of determiners and personal pronouns. Younger children with DLD also produced more word order errors that their TD peers. Furthermore, older children with DLD performed less accurately than younger TD peers, indicating that the SR task taps into morphosyntactic areas of particular difficulty for Danish children with DLD. The classification accuracy associated with SR performance showed high levels of sensitivity and specificity (> 90%) and likelihood ratios indicating good identification potential for clinical and future research purposes. Conclusion SR performance has a strong potential for identifying children with DLD, also in Danish, and with a carefully designed SR task, performance has potential for revealing morphosyntactic difficulties.

Developmental Conditions

Language and communication deficits characterize both autism spectrum disorder and developmental language disorder, and the possibility of there being a common profile of these is a matter of tireless debate in the research community. This experimental study addresses the relation of these two developmental conditions in the critical topic of language. Α total of 103 children (79 males, 24 females) participated in the present study. Specifically, the study’s sample consisted of 40 children with autism, 28 children with developmental language disorder, and 35 typically developing children between 6 and 12 years old. All children completed language and cognitive measures. The results showed that there is a subgroup inside the autism group of children who demonstrate language difficulties similar to children with developmental language disorder. Specifically, two different subgroups were derived from the autism group; those with language impairment and those without. Both autism and language-impaired groups scored lower than typically developing children on all language measures indicating a common pathology in language ability. The results of this study shed light on the relation between the two disorders, supporting the assumption of a subgroup with language impairment inside the autism spectrum disorder population. The common picture presented by the two developmental conditions highlights the need for further research in the field.

Positive Effect

Background. Language disorder is the most frequent developmental disorder in childhood and it has a significant negative impact on children’s development. The goal of the present review was to systematically analyze the effectiveness of interventions in children with developmental language disorder (DLD) from an evidence-based perspective. Methods. We considered systematic reviews, meta-analyses of randomized controlled trials (RCTs), control group cohort studies on any type of intervention aimed at improving children’s skills in the phono-articulatory, phonological, semantic-lexical, and morpho-syntactic fields in preschool and primary school children (up to eight years of age) that were diagnosed with DLD. We identified 27 full-length studies, 26 RCT and one review. Results. Early intensive intervention in three- and four-year-old children has a positive effect on phonological expressive and receptive skills and acquisitions are maintained in the medium term. Less evidence is available on the treatment of expressive vocabulary (and no evidence on receptive vocabulary). Intervention on morphological and syntactic skills has effective results on expressive (but not receptive) skills; however, a number of inconsistent results have also been reported. Only one study reports a positive effect of treatment on inferential narrative skills. Limited evidence is also available on the treatment of meta-phonological skills. More studies investigated the effectiveness of interventions on general language skills, which now appears as a promising area of investigation, even though results are not all consistent. Conclusions. The effectiveness of interventions over expressive and receptive phonological skills, morpho-syntactic skills, as well as inferential skills in narrative context underscores the importance that these trainings be implemented in children with DLD.

Short Term

Background and aims Children with developmental language disorder (DLD) often perform below their typically developing peers on verbal memory tasks. However, the picture is less clear on visual memory tasks. Research has generally shown that visual memory can be facilitated by verbal representations, but few studies have been conducted using visual materials that are not easy to verbalize. Therefore, we attempted to construct non-verbalizable stimuli to investigate the impact of working memory capacity. Method and results We manipulated verbalizability in visual span tasks and tested whether minimizing verbalizability could help reduce visual recall performance differences across children with and without developmental language disorder. Visuals that could be easily verbalized or not were selected based on a pretest with non-developmental language disorder young adults. We tested groups of children with developmental language disorder (N = 23) and their typically developing peers (N = 65) using these high and low verbalizable classes of visual stimuli. The memory span of the children with developmental language disorder varied across the different stimulus conditions, but critically, although their storage capacity for visual information was virtually unimpaired, the children with developmental language disorder still had difficulty in recalling verbalizable images with simple drawings. Also, recalling complex (galaxy) images with low verbalizability proved difficult in both groups of children. An item-based analysis on correctly recalled items showed that higher levels of verbalizability enhanced visual recall in the typically developing children to a greater extent than the children with developmental language disorder. Conclusions and clinical implication: We suggest that visual short-term memory in typically developing children might be mediated with verbal encoding to a larger extent than in children with developmental language disorder, thus leading to poorer performance on visual capacity tasks. Our findings cast doubts on the idea that short-term storage impairments are limited to the verbal domain, but they also challenge the idea that visual tasks are essentially visual. Therefore, our findings suggest to clinicians working with children experiencing developmental language difficulties that visual memory deficits may not necessarily be due to reduced non-verbal skills but may be due to the high amount of verbal cues in visual stimuli, from which they do not benefit in comparison to their peers.
