A Preliminary Comparison of Reading Subtypes in a Clinical Sample of Children With Specific Language Impairment

Speech-Language Pathologists' Perceptions of Language and Literacy Instruction for Pre-K Children With Developmental Language Disorder

PURPOSE

Speech-language pathologists (SLPs) have multiple roles and responsibilities related to language and literacy instruction in schools. The purpose of this exploratory, qualitative study was to analyze school-based SLPs' perceptions related to effective language and early literacy instruction for pre-K children with developmental language disorder (DLD). The goal of this study was to inform development of a new language and early literacy professional development program for inclusive pre-K teachers.

METHOD

Eight school-based SLPs participated in a 1-hr virtual focus group conducted via Zoom recording technology. The researchers used a conventional content analysis approach to analyze the focus group data and identify themes from the discussion.

RESULTS

The researchers developed two themes: (a) SLPs identified repeated exposure to books, peer interaction, and teaching vocabulary with visual supports and props as key elements of language and literacy instruction that can be integrated into a variety of contexts, and (b) SLPs want more time with parents and teachers to support their book reading and model specific language strategies.

CONCLUSIONS

SLPs identified several instructional practices inclusive pre-K teachers could be taught to use during professional development programs to support the emergent literacy development of children with DLD. They also discussed the need for ongoing collaboration between SLPs, caregivers, and teachers to maximize children's early language and literacy experiences. Future research should explore the impact of partnerships with caregivers and teachers on children's language and literacy outcomes.

Conceptions and Misconceptions: What Do School-Based Speech-Language Pathologists Think About Dyslexia?

PURPOSE

The purpose of this exploratory study was to evaluate speech-language pathologists' (SLPs') conceptions and misconceptions about dyslexia.

METHOD

Participants were 86 school-based SLPs. They completed an online survey on which they rated their agreement and disagreement with true and false statements related to the scientific evidence about the nature of dyslexia and interventions for dyslexia, as well as common misconceptions about dyslexia.

RESULTS

There was considerable variability among SLPs' agreement and disagreement with the statements. Critically, despite abundant contrary evidence in the literature, many SLPs believe that dyslexia involves a visual processing deficit.

CONCLUSIONS

These findings suggest that many school-based SLPs hold misconceptions about dyslexia, especially those related to dyslexia being a visual disorder. The identified misconceptions may contribute to some SLPs' reluctance to incorporate reading and prereading skills into speech-language assessment and intervention. SLPs need greater knowledge of dyslexia to provide more effective evaluations and intervention services.

Reading Strategies for Children with Developmental Language Disorder

Developmental language disorder (DLD) is considered a neurodevelopmental disorder that compromises language comprehension and/or expression and constitutes a risk factor for learning to read. The aim of the present study was to analyse the reading strategies used by students with DLD to read sentences. There is evidence in the literature that, when linguistic resources are insufficient, the keyword strategy (identifying some of the words in the sentence with their own semantic content, with barely no processing of the function words) is used to read sentences. A total of 31 primary and secondary school students diagnosed with DLD were evaluated using the PEALE battery. The results reveal that students with DLD present heterogeneous profiles that are below the established reading level for their age. In addition, children with DLD and better reading skills use the keyword strategy to read sentences. In conclusion, clinical and educational implications for reading intervention in individuals with DLD are discussed.

Efficacy of Online Learning Modules for Teaching Dialogic Reading Strategies and Phonemic Awareness

Purpose The purpose of this study was to create and evaluate online learning modules designed to teach speech-language pathologists (SLPs) dialogic reading strategies and phonemic awareness skills. Method School-based SLPs (n = 28) were assigned to complete one of two online learning modules. One module taught dialogic reading strategies, and the other taught phonemic awareness. Participants in the dialogic reading group served as controls for the phonemic awareness group and vice versa. Participants completed a pretest that assessed phonemic awareness skill and knowledge of dialogic reading strategies to control for prior knowledge and skill, completed their assigned module, and then completed a posttest that assessed phonemic awareness skill and knowledge of dialogic reading strategies. Results Data were analyzed using multiple regression. The independent variables were pretest score, group, and the pretest score by group interaction. The dependent variable in the first model was posttest score on the dialogic reading measure. The dependent variable in the second model was posttest score on the phonemic awareness measure. There was a statistically significant group by posttest score interaction in the dialogic reading model, indicating that the dialogic reading module was effective for improving knowledge of dialogic reading strategies. There was not a statistically significant group by posttest score interaction in the phonemic awareness module, indicating that the phonemic awareness module was not effective for improving phoneme segmentation skill and phoneme manipulation skill. Conclusions Online learning modules may be effective for establishing knowledge needed for evidence-based practice in speech-language pathology. Additional research is warranted to determine whether online learning modules can be used to change clinician intervention behavior.

Description and prediction of reading decoding skills in Swedish children with Developmental Language Disorder

AIM

Research is lacking in terms of reading decoding skills among clinical samples of Swedish-speaking children with Developmental Language Disorder (DLD).

METHOD

The present cross-sectional study included a sample of 61 children (8-12 years) with DLD attending school language units, years 1 to 5. Our purpose was to study reading decoding skills and predictors for decoding, such as a phonological processing skill (nonword repetition), working memory, and a family history of literacy problems.

RESULTS

The results on a combined measure of the word and nonword decoding indicated that only 18% of the children had age-adequate decoding skills. The proportion of age-adequate decoders did not change noticeably with the school year. The participants' decoding skills showed larger deviations to test norm means with higher school years. Hierarchical regression analysis showed that the best predictors of decoding skills were measures of working memory and nonword repetition, followed by school year. These factors significantly contributed to the variance in decoding among our sample of children with DLD. A family history of literacy problems made no contribution to the variance. Conclusions: The findings emphasize the necessity of assessing and following up on literacy development in children with DLD.

Diagnosis of Developmental Language Disorder in Research Studies

Purpose The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were identified as having a developmental language disorder or specific language impairment. From these articles, we identified the tests and measures used to identify participants and classify them as healthy or impaired. We then consulted the test manuals and the literature to find information on sensitivity and specificity of the test and the evidence-based cut score that maximized identification accuracy. Results Of the 90 articles examined, 38 (42%) were found to reflect validated diagnostic methods, and 51 (58%) did not. Conclusion Our results illustrate that validated methods are used less than half of the time even by those who should have a high level of expertise and despite calls for increasing scientific rigor in research practices.

Phonogram and word decoding patterns in children with developmental language disorders: Evidence for protracted periods of graphophonemic decoding

PURPOSE

Children with developmental language disorder (DLD) appear to be challenged with word reading problems in a number of ways, yet few investigations in this area are known. Of interest in this exploratory study was how children with DLD decode and recognize words and word parts (phonograms) with irregular (opaque) graphemic properties.

METHOD

Sixty children with DLD and typical language (TLD) in 2nd-5th grade, and 19 college-aged adults, were asked to decode individual phonograms, words and pseudowords, and to identify phonogram forms in a recognition task. Responses were categorized as either reflecting graphophonemic (i.e., a letter-to-sound serial decoding pattern), or target (i.e., irregular graphemic spellings typical of English), or unrelated or incorrect responses (i.e., no apparent adherence to grapheme-phoneme correspondences, or conventional English orthography).

RESULTS

According to logistic regression analyses, children with DLD at each grade level used higher levels of serial, letter-sound correspondences in their decoded productions of isolated phonograms, real and pseudowords relative to their grade-matched peers with TLD and to adults. DLD2 and TLD1 groups performed similarly across the three production tasks. Results on the phonogram recognition task reflected mixed patterns of responding across child and adult groups. Overall DLD participants made more LS only selections than did TLD participants, although DLD and TLD 4th-5th graders performed similarly to each other in their relative selections of target versus target + LS phonogram forms.

CONCLUSIONS

Children with DLD appear to demonstrate protracted stages of graphophonemic serial decoding. A gradual catching-up trend seems to occur over 2nd-5th grades on certain aspects of decoding. A number of developmental considerations and clinical implications for children with DLD are drawn from this study.

Linguistic Contributions to Word-Level Spelling Accuracy in Elementary School Children With and Without Specific Language Impairment

Purpose Children with specific language impairment (SLI) are more likely than children with typical language (TL) to exhibit difficulties in word-level spelling accuracy. More research is needed to elucidate the contribution of linguistic knowledge to word-level spelling accuracy in this population. The purpose of this study was to explore the contributions of linguistic knowledge to spelling accuracy in a group of 2nd- to 4th-grade children with SLI and a group of 2nd- to 4th-grade children with TL. Method Participants were 32 children with SLI and 32 children with TL in Grades 2 through 4. Five areas of linguistic knowledge were assessed: phonological awareness, morphological knowledge, orthographic pattern knowledge, mental grapheme representation knowledge, and vocabulary knowledge. Mixed-effects logistic regression models were utilized to address the research aim. Results Mental grapheme representation knowledge was selected as a significant predictor in both models; however, phonological awareness was the only additional significant predictor in the model for children with SLI, whereas morphological knowledge was the only other significant predictor in the model for children with TL. Orthographic pattern knowledge and vocabulary knowledge were not significant for either group. Conclusions The results suggest that spelling instruction and intervention for children with SLI should take linguistic knowledge into account and explicitly relate linguistic knowledge to spelling. Additionally, future research should consider if instructional targets for children with SLI should differ from targets for children with TL and if these findings represent a delay or a disorder in spelling acquisition for children with SLI.

Pull the Andon Rope on Working Memory Capacity Interventions Until We Know More

Purpose

The purpose of this article is to discuss the current state of interventions for improving working memory (WM) capacity language and academic skills and to provide suggestions for speech-language pathologists working with students who have WM capacity limitations.

Method

Meta-analyses, systematic reviews, randomized controlled trials, and nonrandomized comparison studies investigating the role of WM interventions for improving WM capacity language and academic skills are reviewed. Strategies for improving WM are discussed.

Results

The use of interventions designed to improve WM capacity and other cognitive skills is currently not supported by the research. Direct WM interventions should be considered to be experimental at this time. Such interventions require further investigation before they are used regularly for children with developmental language disorders.

Discussion

Clinicians and practitioners should look to already established interventions for improving how students with developmental language disorders utilize organizational strategies and other well-researched methods for improving their cognitive and academic functioning in functional contexts.

The Potential of Past Tense Marking in Oral Reading as a Clinical Marker of Specific Language Impairment in School-Age Children

Purpose

The purpose of this study was twofold. The first aim was to explore differences in profiles of past tense marking in oral reading of school-age children with specific language impairment (SLI). The second aim was to explore the potential of past tense marking in oral reading as a clinical marker of SLI in school-age children.

Method

This study examined oral readings of connected text to describe the frequency and type of reading errors on regular and irregular past tense verbs for 21 children with SLI as compared to 30 children with typical language in Grades 2 and 3. Each past tense verb token was categorized into 1 of 6 mutually exclusive response types: (a) correctly marked past tense, (b) overmarked past tense, (c) bare stem, (d) other verb inflection, (e) nonverb, or (f) no response. Performance across groups was compared. Additionally, classification statistics were calculated at several cutoffs for regular past tense accuracy and regular past tense finiteness marking.

Results

For regular past tense, there was a significant group difference on accuracy. Children with SLI were less accurate at marking past tense when in oral reading than typical language peers; other response types did not differ. For irregular past tense, there were no group differences. In addition, there was a significant group difference on finiteness marking; this difference was driven by regular but not irregular verbs. A cutoff of 90% for regular past tense accuracy yielded moderate sensitivity and specificity; no cutoff for regular past tense finiteness marking yielded sensitivity above 70%.

Conclusions

Regular past tense accuracy in oral reading provides promise as a clinical marker for diagnosing SLI in school-age children.
