This study examines the production of morphosyntax in Swedish-speaking children diagnosed with Developmental Language Disorder (DLD). Data from a Sentence Repetition Task was used to investigate if there is an implicational order according to Processability Theory (PT) in grammatical structures produced by school-age children with DLD. PT is a cognitive theory of language development that assumes five implicational stages of morphosyntactic development. The analysis was based on a selection of sentences representing the different PT stages. The participants (n = 49; 6;5-11;5 years of age) were recruited from school language units for children with DLD. The results confirm an implicational order: the participants produced structures from a higher stage only if they also produced structures from lower stages. It is suggested that the developmental hierarchy can be used in the intervention of children with DLD by focusing on the next stage. Also, only 26.5% of the participants achieved PT stage 4, and one child (2%) reached the highest PT stage 5. This is discussed in relation to what is known regarding PT stages in typically developing children, as well as associations with language, memory, and non-verbal measures.

This article examines multilingual language use in two groups of children, one group at a state school, and one at a private IB school. The IB school has earlier been assumed to reflect an 'elite' multilingualism. Three research questions are posed: to what extent is the children's language use multilingual, what are their typological profiles, and are there any differences between the two groups in the language use patterns. The agency of the speaker is captured by self-reporting questionnaires. We use a method of circles in which the participant fills in the names and domains of the languages in use. The answers are registered according to three main dimensions: family, social interaction and media use. The study is exploratory and descriptive, and the results demonstrate that a large majority of the children at both schools used more than one language. The study is innovative in combining a sociolinguistic approach with language typology. Our results shed light on children's dynamic and flexible language use, using languages from all of the world's language families. We found similarities in the multilingualism of the two groups, and there was little to indicate that the IB pupils could be characterised as having an 'elite' multilingualism.

This study explores to what extent there is a difference in input in L1 and L2 Swedish regarding word order. Swedish is a V2 language with only one constituent preceding the tensed verb. This phenomenon is acquired in different ways by L1 and L2 learners. L1 learners produce V2 without errors around the age of two years whereas L2 learners experience long-lasting problems with the postverbal placement of the subject. The reason for this difference is not fully understood. This study set out to investigate the characteristics of the ambient language in the two acquisition conditions. The results reveal a lot of variation but also differences in the input which suggest that 'input simplification' is not always helpful.

Little is known about the productive morphosyntax of Norwegian children with developmental language disorder (DLD). The current study examined morphosyntax in Norwegian-speaking children with DLD (n =19) and a control group that was pairwise matched for age, gender, and intelligence quotient (IQ; n = 19). The children's sentence repetitions were studied through the lens of Processability Theory. The group differences were largest for grammatical structures at the latest developmental stage of the processability hierarchy. The Norwegian subordinate clause word order, belonging to the latest stage of the processability hierarchy, stood out as particularly challenging for children with DLD. Only 2 children with DLD but 16 children in the control group produced a subordinate clause with subordinate clause word order. Categorization of children's errors revealed that children with DLD made more errors of all types (addition, omission, substitution, inflection and word order) but especially errors of omission and inflection.

The present study examines the outcome of teaching second language English (L2 English) third-person singular present tense -s for declarative knowledge in two different settings, namely Sweden and Vietnam. Third person -s is one of the most studied grammatical structures in second language acquisition research. Data are collected in two classroom contexts with different teaching traditions. Participants are 76 young learners, 11–12 years old, 32 with Swedish as L1 and 44 with L1 Vietnamese. The results demonstrate differences in learner outcomes in these two groups. The Vietnamese learners outperformed the Swedish learners on the tests of declarative knowledge. The analyses of learner explanations of third-person singular present tense -s reveal that learners tend to decompose this complex rule into several features, which sometimes lead them into misconceptions. This has pedagogical implications about EFL teaching and learning for young learners.

Purpose: There is mounting evidence that the agrammatism that defines Broca's aphasia can be explained in processing terms. However, the extant approach simply describes agrammatism as disparate deficits in a static, mature system. This tutorial aims to motivate and outline a developmental alternative. This alternative is processability theory (PT), a root-to-apex theory of language development, with its origins in the field of second language acquisition, which can connect the findings of aphasia research.

Method: This tutorial critically reviews research on agrammatism as a language deficit, a representational deficit, and a processing phenomenon. Given evidence from research applying PT to language disorders, this tutorial outlines PT's multidimensional architecture of language processing. Using an emergence (onset) criterion, PT predicts fixed developmental stages in word order (syntax) and inflection (morphology) and individual differences in the timing of syntax and morphology. To link PT to agrammatism, this theory's applications to diagnosis and teaching are overviewed, and a case study of five individuals with moderate agrammatism is presented.

Results: Analysis showed that all individuals were positioned in the early PT stages and differed in their timing of syntax and morphology consistent with theoretical predictions.

Conclusions: Evidence from the case study suggests that, although agrammatism results from neural damage and associated language loss, the processing procedures necessary for relearning remain and can be exploited for recovery. A program of diagnosis and intervention is proposed, and future research directions are discussed.

The aim of the present study is twofold: to explore the assessment and intervention practices of Swedish practitioners (mainly Speech Language Therapists: SLTs) for multilingual children with Developmental Language Disorders (DLD) and to explore to which extent they perceive themselves as confident with respect to assessment and intervention. The data comes from the Swedish part of the survey by the European research network (COST1406), including data from 35 countries. In total, 101 practitioners in Sweden answered an online survey. Most of the respondents were female, had a master’s degree, Swedish as their first language (L1), and used only one language in their professional role. All the practitioners answered the first section, 45 of whom also answered questions regarding which languages they use in assessment and intervention with multilingual children. A majority of the participants reported that they encourage parents to use the minority language when communicating with their child at home. The results indicate a context specific DLD intervention approach in which Swedish practitioners tend to emphasize the importance of native language-usage at home. However, due to the amount of missing data, methodological issues need to be taken into consideration.

Our chapter engages with language transfer in SLA with particular focus on the area of grammar. We argue that transfer only plays a minor role in the acquisition of grammatical structures. In order to support our claim, we present data from studies with early and intermediate learners of English.

This paper reports on a case study of a quadrilingual child, Stefan, born and raised in Sweden and exposed to four languages before his first birthday: English, French, Russian and Swedish. We examine his vocabularies in these languages by the Cross-Linguistic Lexical Tasks (Haman, Łuniewska, & Pomiechowska, 2015), designed to measure vocabulary in monolingual and multilingual children. Stefan’s scores on comprehension and production reveal proficiency in all his languages, to varying degrees, and with comprehension exceeding production. While highlighting direct and indirect exposure as explanation for the variation in proficiency, we also discuss cognate vocabulary as an important factor for multilingual language development. In the production tasks, Stefan demonstrates not only vocabulary knowledge but also language-specific use of morphosyntax.
