The Efficacy of Head-Mounted-Display Virtual Reality Intervention to Improve Life Skills of Individuals with Autism Spectrum Disorders: A Systematic Review.

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.

Efficacy, model of delivery, intensity and targets of pragmatic interventions for children with developmental language disorder: A systematic review.

BACKGROUND: It is widely acknowledged that children with developmental language disorder (DLD) predominantly have difficulties in the areas of grammar and vocabulary, with preserved pragmatic skills. Consequently, few studies focus on the pragmatic skills of children with DLD, and there is a distinct lack of studies examining the effectiveness of pragmatic interventions. AIMS: To carry out a systematic review of the literature on pragmatic interventions for children with DLD. METHODS & PROCEDURES: This systematic review was registered with PROSPERO (ID = CRD42017067239). A systematic search in seven databases yielded 1031 papers, of which 11 met our inclusion criteria. The included papers focused on interventions for children with DLD (mean = 3-18 years), enhancing oral language pragmatic skills, published between January 2006 and May 2020, and were based on a group-study design such as randomized control trial or pre-post-testing. Study participants were monolingual speakers. The quality of papers was appraised using the Cochrane Risk of bias tool for randomized controlled trials. OUTCOMES & RESULTS: There was a high degree of variability between the included intervention studies, especially regarding intensity, intervention targets and outcomes. The evidence suggested that pragmatic intervention is feasible for all models of delivery (individual, small and large group) and that interventions for pragmatic language are mostly focused on encouragement of conversation and narrative skills observed through parent-child interaction or shared book-reading activities. CONCLUSIONS & IMPLICATIONS: This study highlights the importance of promoting and explicitly teaching pragmatic skills to children with DLD in structured interventions. A narrative synthesis of the included studies revealed that in addition to direct intervention, indirect intervention can also contribute to improving oral pragmatic skills of children with DLD. WHAT THIS PAPER ADDS: What is already known on the subject? An increasing number of studies have shown that difficulties in acquiring pragmatic language is not only present in children with autism. What this study adds to existing knowledge? Interventions for pragmatic language in children with DLD are mostly focused on encouragement of conversation and narrative skills, very often through parent-child interaction or shared book-reading activities. Interventions that target language pragmatic are feasible for all models of delivery (individual, small and large group). What are the potential or actual clinical implications of this work? The efficacy of the existing studies varies, and it is difficult to give recommendations regarding the intensity and duration of the specific intervention. In addition to offering pragmatic intervention directly from a specialist, pragmatic interventions can also be carried out indirectly if the intervention is under the continuous supervision of a specialist.

Systematic Review: Investigating the Impact of COVID-19 on Mental Health Outcomes of Individuals With ADHD.

BACKGROUND: According to the WHO, the COVID-19 pandemic could have a negative impact on the mental health of individuals, such as an exacerbation of existing difficulties. Individuals with ADHD may be specifically challenged by the pandemic. AIMS: To provide a systematic review of evidence regarding the COVID-19's impact on mental health of individuals with ADHD during the COVID-19 lockdown. METHODS: This registered review (PROSPERO ID CRD42021238770) adhered to Prisma guidelines. Systematic searches in electronic databases PubMed and PsycINFO were carried out. A total of 12 studies covering 3,028 subjects were included. RESULTS: COVID-19 pandemic is associated with increased ADHD symptoms and psychological difficulties. Some studies reported that individuals experienced positive outcomes. The methodological quality of the studies was low to moderate. CONCLUSION: COVID-19 can affect the mental health of individuals with ADHD negatively, although methodological limitations should be considered. Further research should generate knowledge about long-term effects impact of the pandemic and about appropriate support.

"So, I told him to look for friends!" Barriers and protecting factors that may facilitate inclusion for children with Language Disorder in everyday social settings: Cross-cultural qualitative interviews with parents.

PURPOSE: Although researchers have explored parental perspectives on childhood speech and language disorders, this work has mostly been conducted in English-speaking countries. Little is known about parental experiences across countries. Participation in the COST Action IS1406 'Enhancing children's oral language skills across Europe and beyond' provided an opportunity to conduct cross-cultural qualitative interviews. The aims were to explore how parents construe inclusion and/or exclusion of their child and how parents involve themselves in order to facilitate inclusion. METHOD: Parents from nine countries and with a child who had received services for speech-language disorder participated in semi-structured qualitative interviews. We used thematic analysis to analyze the data. RESULTS: Two overarching themes were identified: 'Language disabilities led to social exclusion' and 'Promoting pathways to social inclusion'. Two subthemes were identified Interpersonal relationships are important and Deliberate proactiveness as stepping stones for social inclusion. CONCLUSIONS: Across countries, parents report that their children's hidden disability causes misunderstandings that can lead to social exclusion and that they are important advocates for their children. It is important that the voices and experiences of parents of children with developmental disabilities are understood and acknowledged. Parents' recommendations about how to support social inclusion need to be addressed at all levels of society.

Exploring Parental Perspectives of Childhood Speech and Language Disorders Across 10 Countries: A Pilot Qualitative Study.

Purpose Although researchers have explored parental perspectives of childhood speech and language disorders, most studies have been conducted in English-speaking countries. Little is known about parental experiences across countries, where procedures of language screening and services for language disorders differ. The authors participated in the COST 1 Action network IS1406, "Enhancing Children's Oral Language Skills Across Europe and Beyond," which provided an opportunity to conduct cross-country qualitative interviews with parents. The aim of this pilot study was to explore ways in which parents construed and described speech and language disorders across countries. Method Semistructured qualitative interviews were conducted with parents from 10 families in 10 different countries. The data were analyzed using thematic analysis. Findings The overall theme was "acknowledging parental expertise." The parents described, in detail, ways in which their children's speech and language (dis)abilities had an impact on the children's everyday life. Three subthemes were identified: impairment, disability, and changes over time. Conclusions The findings suggest that, across a range of countries, parents demonstrated contextualized understandings of their children's speech and language (dis)abilities, along with the everyday functional implications of the disorders. Hence, despite not holding professional knowledge about language disorders, the voices, views, understandings, and personal experiences of parents in relation to their child's disorder should be listened to when planning therapy services.

The role of severity and intentionality in the intensity of Schadenfreude attribution: A developmental study of Danish children.

Understanding envy and schadenfreude requires complex interpersonal social cognitive abilities, such as social comparison and evaluating the Self, but also understanding agency and intentionality. Previous studies of children's development of envy/schadenfreude addressed whether children understand and experience schadenfreude as opposed to compassion/sympathy or whether children's attribution of schadenfreude is a consequence of envy provoked by a disadvantageous social comparison. In this study, we take a step further and investigate the roles that agency and severity of the damage play in mediating children's attribution of schadenfreude. The participants were 144 Danish children aged 3-9 years divided into two age groups. Children were presented with eight stories supported by pictures showing intentional versus accidental and irreparable versus reparable damage to envied objects. The results show that the intensity of envy/schadenfreude, as well as the happy victimizer phenomenon, varies depending on the severity of damage, agency and intentionality. When damage is accidental, schadenfreude is expressed with less intensity compared to when damage is intentional (led by an agent). When damage is irreparable, children attribute less intense feelings of schadenfreude compared to when it is reparable. In addition, only the older children expressed reparable damage carrying more intense schadenfreude and only in the accidental condition. In general, children consider intentional and reparable damage more intense than accidental and irreparable damage, and this is mediated by age. The results are important for understanding the developmental trajectory of children's complex emotions and for educational programmes directed towards supporting this development.

Cross-linguistic patterns in the acquisition of quantifiers.

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.

Theory of Mind in Children With Specific Language Impairment: A Systematic Review and Meta-Analysis.

The relation between language and theory of mind (ToM) has been debated for more than two decades. In a similar vein, ToM has been examined in children with specific language impairment (SLI), albeit with inconsistent results. This meta-analysis of 17 studies with 745 children between the ages of 4 and 12 found that children with SLI had substantially lower ToM performance compared to age-matched typically developing children (d = .98). This effect size was not moderated by age and gender. By revealing that children with SLI have ToM impairments, this finding emphasizes the need for further investigation into the developmental interface between language and ToM as well as the extended consequences of atypical language development.

Ratings of age of acquisition of 299 words across 25 languages: Is there a cross-linguistic order of words?

We present a new set of subjective age-of-acquisition (AoA) ratings for 299 words (158 nouns, 141 verbs) in 25 languages from five language families (Afro-Asiatic: Semitic languages; Altaic: one Turkic language: Indo-European: Baltic, Celtic, Germanic, Hellenic, Slavic, and Romance languages; Niger-Congo: one Bantu language; Uralic: Finnic and Ugric languages). Adult native speakers reported the age at which they had learned each word. We present a comparison of the AoA ratings across all languages by contrasting them in pairs. This comparison shows a consistency in the orders of ratings across the 25 languages. The data were then analyzed (1) to ascertain how the demographic characteristics of the participants influenced AoA estimations and (2) to assess differences caused by the exact form of the target question (when did you learn vs. when do children learn this word); (3) to compare the ratings obtained in our study to those of previous studies; and (4) to assess the validity of our study by comparison with quasi-objective AoA norms derived from the MacArthur-Bates Communicative Development Inventories (MB-CDI). All 299 words were judged as being acquired early (mostly before the age of 6 years). AoA ratings were associated with the raters' social or language status, but not with the raters' age or education. Parents reported words as being learned earlier, and bilinguals reported learning them later. Estimations of the age at which children learn the words revealed significantly lower ratings of AoA. Finally, comparisons with previous AoA and MB-CDI norms support the validity of the present estimations. Our AoA ratings are available for research or other purposes.

Alterations in the rate of limb movement using a lower body positive pressure treadmill do not influence respiratory rate or phase III ventilation.

The purpose of this study was to determine the effect of alterations in rate of limb movement on Phase III ventilation during exercise, independent of metabolic rate, gait style, and treadmill incline. Subjects completed five submaximal exercise bouts on a lower body positive pressure treadmill (AlterG P 200). The percent body weight for the five exercise bouts was 100, 87, 75, 63, and 50% and each was matched for carbon dioxide production (V CO2 ). Naturally, to match the V CO2 while reducing the body weight up to 50% of normal required a significant increase in the treadmill speed from 3.0 ± 0.1 to 4.1 ± 0.2 mph, which resulted in a significant (P < 0.05) increase in the mean step frequency (steps per minute) from 118 ± 10 at 3 mph (i.e., 100% of body weight) to 133 ± 6 at 4.1 mph (i.e., 50% of body weight). The most important finding was that significant increases in step frequency did not significantly alter minute ventilation or respiratory rate. Such results do not support an important role for the rate of limb movement in Phase III ventilation during submaximal exercise, when metabolic rate, gait style, and treadmill incline are controlled.

Annoying Danish relatives: comprehension and production of relative clauses by Danish children with and without SLI.

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.

Ambulatory monitoring of arm movement using accelerometry: an objective measure of upper-extremity rehabilitation in persons with chronic stroke.

OBJECTIVE: To evaluate the reliability and validity of accelerometry for measuring upper-extremity rehabilitation outcome. DESIGN: Validation study. SETTING: Data recorded in the community. PARTICIPANTS: Consecutive Constraint-Induced Movement therapy (CIMT) patients (n = 10) and volunteer community residents with stroke (n = 10). All participants were more than 1 year poststroke and had mild to moderate motor impairment of the more affected arm. INTERVENTION: All study participants were asked to wear accelerometers outside the laboratory for 3 days immediately before and after treatment, or for an approximately equivalent no-treatment period (controls). MAIN OUTCOME MEASURES: Participants wore an accelerometer on each arm, the chest, and the more affected leg and completed the Motor Activity Log (MAL), which is a semistructured interview of real-world arm use. RESULTS: Test-retest reliability of transformed accelerometer recordings was greater than .86. There was also a large increase in the ratio of transformed more- to less-impaired arm recordings in CIMT therapy patients (d' = 0.9, P < .05), while there was no change for controls. The correlation between this parameter and the MAL was .74 (P < .001). CONCLUSIONS: Accelerometry provides an objective, real-world index of upper-extremity rehabilitation outcome and has good psychometric properties.
