Nonword Repetition Performance Differentiates Children Who Stutter With and Without Concomitant Speech Sound and Developmental Language Disorders

Purpose: The aim of this study was to examine how nonword repetition (NWR) performance may be impacted by the presence of concomitant speech and language disorders in young children who stutter (CWS). Method: One hundred forty-one children (88 CWS and 53 children who do not stutter [CWNS]) participated. CWS were divided into groups based on the presence of speech sound and/or language disorder or typical speech sound production and language abilities. NWR abilities were measured using stimuli composed of one- to four-syllable nonwords. Results: CWS with typical speech and language and CWNS had higher accuracy scores than CWS with concomitant speech and language disorders. We found no difference in accuracy scores between CWNS and CWS with typical speech and language abilities, nor did we find differences between CWS with speech sound disorder and CWS with both speech sound and language disorders. Accuracy decreased as nonword length increased for all groups. Conclusions: We found that the presence of a concomitant speech and language disorder was a driving factor behind poorer NWR performance in CWS. Accuracy scores differentiated CWS with concomitant disorders from CWS with typical speech and language but not CWS with typical speech and language from CWNS. Considering the speech and language abilities of CWS helped clarify poorer NWR performance and enhances generalizability to the population that exists clinically.

Poverty Effects on Oral Language Development

This chapter focuses on oral language development in children birth to third grade. Additionally, the effects of poverty on oral language development in children is explored. Subject matter includes typical language development, common language disorders, and current information regarding the interplay of language and technology. Particular attention is paid to the ways the home environment influences early language in infants and toddlers. Strategies to support language development in young children through the language experience approach, literacy, text sets, and technology are explained. Resources, materials, and suggested activities for parents, caregivers, and educators are embedded.

Clinical Features of Stroke

Stroke is a clinical condition that causes neurological dysfunction due to focal infarction or haemorrhage in the brain, spinal cord, or retina. These clinical features may take 24 hours or more and result in death. Stroke is one of the leading causes of disability and death. With the prolongation of life in societies, stroke and stroke-related risk factors become more and more important. Age, gender, race, heredity, ethnicity, hypertension, atrial fibrillation, diabetes, hyperlipidemia, smoking, transient ischemic attack, and physical inactivity are risk factors of stroke. Signs and symptoms of stroke vary according to occluded vessel. Mental dysfunction, speech and language disorders, motor and sensory impairment may occur as a result of stroke.

Special Needs Assessment in Bilingual School-Age Children in Germany

Educational and (psycho-)linguistic research on L1 and L2 acquisition in bilingual children sketches them as a group of language learners varying in many aspects. However, most studies to date have based evaluations of language proficiency or new assessment tools on data from heritage children, while studies on the appropriateness of assessment tools for school-age refugee children remain a notable exception. This study focuses on the standardized assessment tool BUEGA for primary school children, which is, among others, a widespread tool for the assessment of pedagogical support or special needs (SN) in Germany. We compare the performance of 12 typically developing monolinguals (Mo-TD: 7;3–12;1), 14 heritage-bilinguals (BiTD: 7;1–13;4, L1 Turkish and Arabic), 12 refugee- students (BiTD: 8;7–13;1, L1 Arabic), and 7 children with developmental language disorders (DLD: 7;7–13;9) on the subtests of grammar, word-reading, and spelling. Overall results show that refugee-BiTDs perform in the (monolingual) pathology range. No significant differences emerged between students with DLD and typically developing (TD) refugee students. Considering the assessment of school-related language performance, bilingual refugees are at risk of misdiagnosis, along with the well-known effects of educational disadvantage. This particularly applies to children with low socioeconomic status (SES). Looking beyond oral language competencies and using test combinations can help exclude language disorders in school-age children with limited L2 proficiency.

A new perspective on referentiality in elicited narratives: Introduction to the Special Issue

This special issue investigates the use of referential expressions in elicited picture-based narratives by children with and without developmental language disorders, across a range of languages and language combinations. All contributions use the Multilingual Assessment Instrument for Narratives (MAIN, Gagarina et al. 2012, 2019). The studies featured in this issue cover monolingual and bilingual children aged 4–11 years, but focus mainly on age 4–7, a period in a child’s life where great strides are made in the development of narrative skills. This collection of papers offers a new perspective on referentiality for several reasons: all studies use the same stimuli and by and large the same procedure for the elicitation of narratives. The stimuli, four picture-based stories, are controlled for comparability of protagonists, plot and story structure. They were designed as a ‘visual’ representation of a multidimensional model of story grammar. This methodological and theoretical base allows for a comparative investigation of referentiality (including reference introduction, maintenance and reintroduction) in narratives, across languages and populations. This introduction addresses theoretical aspects of referentiality in decontextualised discourse and reviews the literature regarding the impact of language-specific referential systems and the age and path of acquisition in typically developing children and children with developmental language disorders. We also discuss methodological aspects of eliciting referentiality in narratives in detail. This introduction thus seeks explanations for the diverse and sometimes contradictory empirical results regarding children’s mastery of referentiality. Finally, an overview of the contributions in the special issue is given.

The Early Prelinguistic Skills in Iranian Infants and Toddlers

Objectives: The prelinguistic skills which pave the way for language development have always been an area of research in the Speech Therapy field. Although studying these skills is important, there is a study gap among Persian children. Therefore, this study explored prelinguistic skills among a sample of Persian-speaking children aged 6 to 24 months and made a comparison between different age groups. We also studied the effects of gender and family history of speech-language disorders on children’s prelinguistic abilities. Methods: In the present study, 277 mothers of Iranian Persian-speaking children aged 6 to 24 months were asked to fill a research-made checklist that evaluated the prelinguistic skills of their children. This study was cross-sectional and was conducted in Tehran City, Iran, in 2021. Children’s abilities in different age groups were compared using the analysis of variance (ANOVA), Scheffe test, the Kruskal-Wallis test, and the post-hoc test. The differences between the total scores of the two genders were also determined using the Mann-Whitney U test. Results: Comparing the prelinguistic skills in different age groups indicated a statistically significant increase in the scores as children grow up. Children with a positive family history of speech-language disorders scored lower on the checklist than the others (91.03±17.37). Furthermore, there were statistically significant differences between the two genders in developing gesture, vocalization, first words, social interaction, imitation, and play; girls had higher scores. Conclusion: Based on the studies conducted in different countries, prelinguistic skills develop as children grow up; these skills facilitate language acquisition and other social skills. The present study also demonstrated the development of these skills alongside children’s development. This similarity between Persian-speaking children and other children from different cultures and languages, as well as better performance in children with a negative family history of speech-language impairments, confirm the role of genetic factors in children’s development. Moreover, the differences in the development of some prelinguistic skills between girls and boys reveal the impact of various factors, such as social factors, on prelinguistic skills development.

What Language Disorders Reveal About the Mechanisms of Morphological Processing

We addressed an understudied topic in the literature of language disorders, that is, processing of derivational morphology, a domain which requires integration of semantic and syntactic knowledge. Current psycholinguistic literature suggests that word processing involves morpheme recognition, which occurs immediately upon encountering a complex word. Subsequent processes take place in order to interpret the combination of stem and affix. We investigated the abilities of individuals with agrammatic (PPA-G) and logopenic (PPA-L) variants of primary progressive aphasia (PPA) and individuals with stroke-induced agrammatic aphasia (StrAg) to process pseudowords which violate either the syntactic (word class) rules (*reheavy) or the semantic compatibility (argument structure specifications of the base form) rules (*reswim). To this end, we quantified aspects of word knowledge and explored how the distinct deficits of the populations under investigation affect their performance. Thirty brain-damaged individuals and 10 healthy controls participated in a lexical decision task. We hypothesized that the two agrammatic groups (PPA-G and StrAg) would have difficulties detecting syntactic violations, while no difficulties were expected for PPA-L. Accuracy and Reaction Time (RT) patterns indicated: the PPA-L group made fewer errors but yielded slower RTs compared to the two agrammatic groups which did not differ from one another. Accuracy rates suggest that individuals with PPA-L distinguish *reheavy from *reswim, reflecting access to and differential processing of syntactic vs. semantic violations. In contrast, the two agrammatic groups do not distinguish between *reheavy and *reswim. The lack of difference stems from a particularly impaired performance in detecting syntactic violations, as they were equally unsuccessful at detecting *reheavy and *reswim. Reduced grammatical abilities assessed through language measures are a significant predictor for this performance, suggesting that the “hardware” to process syntactic information is impaired. Therefore, they can only judge violations semantically where both *reheavy and *reswim fail to pass as semantically ill-formed. This finding further suggests that impaired grammatical knowledge can affect word level processing as well. Results are in line with the psycholinguistic literature which postulates the existence of various stages in accessing complex pseudowords, highlighting the contribution of syntactic/grammatical knowledge. Further, it points to the worth of studying impaired language performance for informing normal language processes.
