Overall Performance

There are not many studies dealing with a comparison of the eye movements of individuals with dyslexia and developmental language disorder (DLD). The aim of this study is to compare the eye movements in the two most common language disorders, dyslexia and DLD and to consider their contribution to diagnostics. In the research the oculomotor test was administered to 60 children with the clinical diagnosis of dyslexia or DLD and 58 typically developing children (controls). The test included a prosaccadic task, antisaccadic task and a nonverbal sequential task with self-regulation of the pace. Controls could be singled out from other two clinical groups by means of the oculomotor imaging. Both of the clinical groups in comparison with the controls were characterized by worse overall performance. Through the employment of the oculomotor it was possible to differentiate between both of the clinical groups. The dyslexics had an overall worse oculomotor performance than the DLD group. The results of the study show that the oculomotor test has the potential to contribute to diagnostics of dyslexia and DLD and the screening of these disorders at pre-school age.

Experimental Trials

Purpose This study examined whether college students with developmental language disorder (DLD) showed similar sensitivity to verb bias information during real-time sentence processing as typically developing (TD) peers. Method Seventeen college students with DLD and 16 TD college students participated in a mouse-tracking experiment that utilized the visual world paradigm to examine real-time sentence processing. In experimental trials, participants chose 1 of 2 pictured interpretations of a sentence. Measures of interest were the choice of interpretation and the amount of competition from the unchosen picture as measured by mouse curvature. Results Choice of interpretation and mouse movements by college students with DLD suggested less sensitivity to verb bias information than their TD peers. Conclusion College students with DLD showed less evidence of sensitivity to verb bias information than their TD peers in this task. Their performance may reflect the use of compensatory processing strategies and may be related to poor comprehension abilities often observed in this population.

Phonological Complexity

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 purpose of this article is to situate the recent language disorder label debate within a school's perspective. As described in two recent The ASHA Leader articles, there is international momentum to change specific language impairment to developmental language disorder . Proponents of this change cite increased public awareness and research funding as part of the rationale. However, it is unclear whether this label debate is worthwhile or even practical for the school-based speech-language pathologist (SLP). A discussion of the benefits and challenges to a shift in language disorder labels is provided. Conclusions Although there are important arguments for consistency in labeling childhood language disorder, the reality of a label change in U.S. schools is hard to imagine. School-based services are driven by eligibility through the Individuals with Disabilities Education Act, which has its own set of labels. There are myriad reasons why advocating for the developmental language disorder label may not be the best use of SLPs' time, perhaps the most important of which is that school SLPs have other urgent priorities.

Purpose We examined indices of narrative microstructure as metrics of language development and impairment in Arabic-speaking children. We examined their age sensitivity, correlations with standardized measures, and ability to differentiate children with average language and language impairment. Method We collected story narratives from 177 children (54.2% boys) between 3.08 and 10.92 years old ( M = 6.25, SD = 1.67) divided into six age bands. Each child also received standardized measures of spoken language (Receptive and Expressive Vocabulary, Sentence Imitation, and Pseudoword Repetition). Several narrative indices of microstructure were examined in each age band. Children were divided into (suspected) developmental language disorder and typical language groups using the standardized test scores and compared on the narrative indicators. Sensitivity and specificity of the narrative indicators that showed group differences were calculated. Results The measures that showed age sensitivity included subject omission error rate, number of object clitics, correct use of subject–verb agreement, and mean length of utterance in words. The developmental language disorder group scored higher on subject omission errors (Cohen's d = 0.55) and lower on correct use of subject–verb agreement (Cohen's d = 0.48) than the typical language group. The threshold for impaired performance with the highest combination of specificity and sensitivity was 35th percentile. Conclusions Several indices of narrative microstructure appear to be valid metrics for documenting language development in children acquiring Gulf Arabic. Subject omission errors and correct use of subject–verb agreement differentiate children with typical and atypical levels of language development.

Purpose This exploratory study describes the emergent literacy skills of children with developmental language disorder (DLD) who speak Spanish, a language with a simple phonological structure and transparent orthography. We examine differences between children with DLD and their typically developing (TD) peers on a battery of emergent literacy measures. Method Participants included 15 monolingual Spanish-speaking children with DLD (who did not present with cognitive difficulties) and 15 TD controls matched for age, gender, and socioeconomic status, ranging in age from 3;10 to 6;6 (years;months; M age = 4;11). All children completed a battery of comprehension-related emergent literacy tasks (narrative retell, print concept knowledge) and code-related emergent literacy tasks (beginning sound, rhyming awareness, alphabet knowledge, and name-writing ability). Results On average, children with DLD performed significantly worse than TD controls on a battery of comprehension- and code-related emergent literacy measures. On all code-related skills except rhyming, children with DLD were more likely than their TD peers to score “at risk.” Conclusions The results suggest some universality in the effect of DLD on reading development. Difficulties with emergent literacy that are widely documented in English-speaking children with DLD were similarly observed in Spanish-speaking children with DLD. Future research should explore long-term reading outcomes in Spanish for children with DLD.
