It was not possible to identify ASD prevalence studies for Greenland. However, for the remaining countries descriptive increases in ASD prevalence figures were observed. Increases were evident both in relation to age and birth cohort. Studies varied regarding which age group and cohort prevalence figures were reported. The most reported age group was the 7– 12-year-olds. In this group, recent prevalence figures for Denmark ranged from 0.26% to 1.47%, in Norway 0.6%, in Sweden 0.23– 0.68%, in Finland 0.22– 0.86%, and in Iceland 2.40– 3.13%. Iceland stood out in terms of higher prevalence figures compared to the other Scandinavian and Nordic countries. Two studies from the Faroe Islands reported ASD prevalence rates between 0.50% and 0.94% for 7– 24-year-olds. These studies were based on nationwide figures, but not from national or official registers.Discussion and conclusion: This study documented increasing prevalence of ASD in Scandinavian and Nordic countries. Several explanations of aspects that may contribute to the increases were discussed, eg, heightened awareness of ASD and earlier diagnosis. The importance of considering differences in data sources was discussed, with an emphasis on the importance of using national registries when available as this source is the most reliable and valid. The absence of prevalence figures for Greenland may be attributed to structural as well as cultural aspects, eg, two parallel systems assessing ASD, cultural taboos as well as lack of awareness of ASD. Suggestions or how to gain knowledge on ASD prevalence in Greenland is presented.Keywords: autism spectrum disorder, prevalence, Scandinavia, Nordic

Nikki M Skjoldborg, Patrick K Bender, Kristine M Jensen de López Center for Developmental & Applied Psychological Science, Department of Communication and Psychology, Aalborg University, Aalborg, DenmarkCorrespondence: Kristine M Jensen de López, Email kristine@ikp.aau.dkAbstract: Challenges in life skills in individuals with autism spectrum disorders (ASD) are associated with dependency on others and increased isolation from peers. In recent years, interventions using virtual reality (VR) technology have been proposed to improve life skills in ASD populations. This systematic review seeks to evaluate the efficacy of employing VR interventions mediated via head-mounted displays (HMD) for the improvement of life skills in individuals with ASD. Several databases were searched and a narrative synthesis was conducted to examine the findings of the included studies. Eight studies including a total of 58 participants were deemed relevant for this systematic review. The methodological quality of the included studies was assessed via the use of critical appraisal tools. Results were generally positive, with one study reporting statistically significant results, and one study not reporting any change in abilities. The remaining six studies reported varying degrees of life skill improvement. The studies were characterized by methodological issues, such as very low sample sizes. The findings of this systematic review indicate some potential for HMD VR interventions in the improvement of life skills in individuals with ASD. However, this review also highlights the current lack of methodologically strong study designs, which prohibits any firm conclusions. Findings are discussed regarding methodological recommendations for further research as well as practical implications for life skills interventions for individuals with ASD.Keywords: virtual reality, autism spectrum disorder, life skills, social skills, head-mounted displays, intervention

Background: Research on the grammatical characteristics of children with developmental language disorder (DLD) across languages has challenged accounts about the nature of DLD. Studies of the characteristics of DLD in different languages can reveal which components of DLD emerge irrespective of language and which components are language specific., Aims: To examine the grammatical characteristics of children with DLD acquiring Danish (microstructure and error types) in order to contribute to research on language-general and language-specific characteristics of DLD., Methods & Procedures: Language samples from two telling narratives, one retelling narrative and one session of semi-spontaneous talk were collected from 39 Danish-speaking children aged 5;0-8;6, comprising one group of children with DLD (n = 15) and two control groups (age- and language-matched: n = 15 and = 9, respectively). The data were analysed with reference to microstructure and grammatical errors. The DLD children's performance was compared with that of their peers with typical language development (AM) and to that of a younger group matched on language comprehension (LM). Task effects were also analysed., Outcomes & Results: A significant group difference in microstructure was present in the results for mean length of utterance (MLU), where the AM group had significant higher MLU compared with the DLD group. Two variables clearly distinguished DLD children from both AM and LM children in terms of errors, namely word order errors and omission errors. The analysis of grammatical errors also revealed that the most salient challenges for Danish-speaking children with DLD were not clearly morphological in nature. Although the children with DLD, as expected, made more morphological errors compared with the AM group, they did not produce more errors compared with the LM group. Task effects were present for some but not all results., Conclusions & Implications: This research emphasizes the importance of cross-linguistic comparisons of the linguistic error profiles in the elicited language of children with DLD and the importance of considering the methodological context when analysing the grammatical language abilities of children with DLD. The results are relevant for clinicians and for developing screening tools., What This Paper Adds: What is already known on this subject DLD is characterized by challenges in producing and comprehending language. Ample research is available on English-speaking children with DLD, and which has reported on challenges acquiring morphology. Studies of children with DLD acquiring other languages than English show challenges related to specific grammatical features of the respective language. What this study adds to the existing knowledge This study is the first to investigate microstructure abilities and grammatical errors produced by Danish-speaking children with DLD and using different language samples (narrative telling, narrative retelling and spontaneous language). It enhances our knowledge about DLD in Scandinavian languages and cross-linguistically and reinforces cross-linguistic findings that grammatical and structural challenges in language acquisition for children with DLD might not be reducible exclusively to morphology. While some components of DLD children's language challenges may appear universal and be attributed to overarching factors other components seem more specific to the structure of the target language. Results from this study additionally draw attention to the importance of considering contextual constraints when investigating productive grammatical abilities in children with DLD. What are the practical and clinical implications of this work? More detailed analysis of grammatical error types seen in children with DLD acquiring languages other than English and of individual differences contribute to clinical advancement in the field. A better insight into grammatical difficulties of Danish-speaking children with DLD may contribute to improved assessment procedures and planning of therapy for children with DLD., (© 2024 The Author(s).

Objective: To provide an in-depth examination of whether pragmatic, expressive, receptive, and narrative language are associated with the social and academic functioning of children with ADHD., Method: Children with ADHD ( n  = 46) and neurotypical comparison (NC) children ( n  = 40) aged 7 to 11 years completed tasks measuring expressive, receptive, and narrative language, while parents rated pragmatic language and social- and academic functioning., Results: Children with ADHD differed significantly from NC children on pragmatic language, expressive language, receptive language, and narrative coherence. An examination of indirect effects revealed that a significant proportion of the association between ADHD and social functioning was shared with pragmatic language, while a significant proportion of the association between ADHD and academic difficulties was shared with pragmatic language as well as with expressive language., Conclusion: This preliminary study supports the clinical relevance of language in relation to the academic- and social functioning of children with ADHD., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

This article contributes as a commentary to Min's critical evaluation of the challenges and resistances that have presented themselves during the recent process of changing the pedagogical practices ofChinese preschools to more closely resemble those seen in Scandinavian. The focus is on how decisions of how to structure the particular environment in preschool settings have direct and indirect implications for children's learning and learning possibilities, and the importance of understanding these as mediated signifiers of the particular culture values. The discussions stress the importance of weighing cross-cultural pedagogical practices in terms of the functions they each serve in themselves, and in regard to the sociocultural history from which they have emerged and serve within. This means enculturation of new didactic practices should be understood as a gradual, smooth processes that allows itself to merge useful aspects of new educational models and practices with existing practices and cultural values.

Learners of most languages are faced with the task of acquiring words to talk about number and quantity. Much is known about the order of acquisition of number words as well as the cognitive and perceptual systems and cultural practices that shape it. Substantially less is known about the acquisition of quantifiers. Here, we consider the extent to which systems and practices that support number word acquisition can be applied to quantifier acquisition and conclude that the two domains are largely distinct in this respect. Consequently, we hypothesize that the acquisition of quantifiers is constrained by a set of factors related to each quantifier's specific meaning. We investigate competence with the expressions for "all," "none," "some," "some…not," and "most" in 31 languages, representing 11 language types, by testing 768 5-y-old children and 536 adults. We found a cross-linguistically similar order of acquisition of quantifiers, explicable in terms of four factors relating to their meaning and use. In addition, exploratory analyses reveal that language- and learner-specific factors, such as negative concord and gender, are significant predictors of variation., Competing Interests: The authors declare no conflict of interest.

This study examines the comprehension and production of subject and object relative clauses (SRCs, ORCs) by children with Specific Language Impairment (SLI) and their typically developing (TD) peers. The purpose is to investigate whether relative clauses are problematic for Danish children with SLI and to compare errors with those produced by TD children. Eighteen children with SLI, eighteen TD age-matched (AM) and nine TD language-matched (LM) Danish-speaking children participated in a comprehension and in a production task. All children performed better on the comprehension compared with the production task, as well as on SRCs compared to ORCs and produced various avoidance strategies. In the ORC context, children with SLI produced more reversal errors than the AM children, who opted for passive ORCs. These results are discussed within current theories of SLI and indicate a deficiency with the assignment of thematic roles rather than with the structural make-up of RCs.
