Such investigations are important to identify key cognitive processes underlying eyewitness recall, and assess how predictive such measures are compared to intelligence, diagnostic group status (autism or typically developing) and age. Methods A total of 272 children (162 boys, 110 girls) of age 76 months to 142 months (M = 105 months) took part in this investigation: 71 children with autism and 201 children with typical development. The children saw a staged event involving a minor mock crime and were asked about what they had witnessed in an immediate Brief Interview. This focused on free recall, included a small number of open-ended questions, and was designed to resemble an initial evidence gathering statement taken by police officers arriving at a crime scene. Children were also given standardised tests of intelligence, memory, language, and attention. Results & conclusions Despite the autism group recalling significantly fewer items of correct information than the typically developing group at Brief Interview, both groups were equally accurate in their recall: 89% of details recalled by the typically developing group and 87% of the details recalled by the autism group were correct. To explore the relationship between Brief Interview performance and the cognitive variables, alongside age, diagnostic group status and non-verbal intelligence quotient, multiple hierarchical regression analyses were conducted, with Brief Interview performance as the dependant variable. Age and diagnostic group status were significant predictors of correct recall, whereas non-verbal intelligence was less important. After age, non-verbal intelligence, and diagnostic group status had been accounted for, the only cognitive variables that were significant predictors of Brief Interview performance were measures of memory (specifically, memory for faces and memory for stories). There was little evidence of there being differences between the autism and typically developing groups in the way the cognitive variables predicted the Brief Interview. Implications The findings provide reassurance that age – the most straightforward information to which all relevant criminal justice professionals have access – provides a helpful indication of eyewitness performance. The accuracy of prediction can be improved by knowing the child’s diagnostic status (i.e. whether the child is on the autism spectrum), and further still by using more specific assessments (namely memory for faces and memory for stories), possibly via the input of a trained professional. Importantly, the findings also confirm that whilst children with autism may recall less information than typically developing children, the information they do recall is just as acc","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941517722139","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42157947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Friedmann","doi":"10.1177/2396941517714945","DOIUrl":"https://doi.org/10.1177/2396941517714945","url":null,"abstract":"Background and aims On average, autistic individuals make more errors than control participants when reading aloud sentences containing heterophonic homographs—written words with multiple meanings and pronunciations. This finding is widely interpreted within the framework of “weak central coherence” as evidence for impaired sentence-level comprehension resulting in a failure to disambiguate the homograph meaning. However, consistent findings at the group level belie considerable individual variation. Our aim here was to determine whether that variation was reliable and whether it could be predicted. Methods We developed a Hebrew version of the homograph-reading test, containing many more items than is possible in English. The test was administered to 18 native-Hebrew speaking autistic children and adolescents, along with a battery of reading and language assessments. Results Participants with autism showed wide individual variation in performance on the homograph-reading task. Using a mixed random effects logistic regression analysis, we showed that measures of autism severity, single word reading, and single word comprehension all left reliable individual variation unaccounted for and none accounted for variation beyond that associated with the child’s age. Instead, homograph reading was best predicted by performance on a picture naming task, which accounted for unique variation beyond age and each of the other predictors. Conclusions Poor performance of autistic individuals on the English version of the homograph-reading task has until now been characterized as evidence for a comprehension deficit in autism. However, the results of the current study lead us to propose a new working hypothesis—that difficulties affecting some autistic individuals reflect impairment in the use of semantics to guide the selection of the appropriate phonological form during speech production. This hypothesis is consistent with the strong association between homograph reading and picture naming. It may also help explain the inconsistent pattern of results across studies using different measures of linguistic “central coherence.” Implications The results of this preliminary study should be replicated before firm conclusions are drawn. Nonetheless, the study serves to emphasize the importance of considering within-group as well as between-group variations in studies of autism. It also provides a worked example showing how mixed random effect analyses can be used to explore individual differences, distinguishing between genuine variation and psychometric noise.","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941517714945","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45934146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst it is unlawful to exclude children due to their needs, school exclusion is common amongst children with special educational needs, including autism. Currently, little is known about experiences of school exclusion from the perspectives of autistic students and/or their parents. This is particularly the case for girls on the autism spectrum. Methods Semi-structured interviews were conducted with eight autistic girls and their parents (seven mothers, one father). Interviews explored experiences of mainstream schooling; alternative educational provisions that were offered (if any); the school exclusion process; and the girls’ current educational provision. As well as asking the girls and their parents about positive and negative aspects of their past and current experiences, participants were asked to reflect on areas for potential improvements. Results Interviews were analysed using thematic analysis and three key themes emerged from the data: inappropriate school environments (including problems with the sensory environment, difficulties when placed with inappropriate peers and general pressures of mainstream classrooms), tensions in school relationships (including problems with staff and peers, alongside a general lack of communication), and problems with staff responses (including a perceived lack of understanding of the girls’ needs and a lack of appropriate support being provided, resulting in ‘battles’ between parents and schools). Conclusions The themes and subthemes that emerged from the interviews were not unique to autistic girls. Indeed, issues such as inappropriate school environments, a lack of staff understanding and breakdowns in relationships have been repeatedly raised by parents and young autistic people (mostly boys) in other studies, albeit in different environments. Nevertheless, the results highlight that more needs to be done to positively influence the direction of the girls’ educational journeys. Implications To improve the inclusion of autistic girls, it is recommended that educational establishments be proactive in developing inclusive environments, build positive relationships (both in and outside of the classroom) and, if exclusion is unavoidable, better support students both before and after the process.","PeriodicalId":36716,"journal":{"name":"Autism and Developmental Language Impairments","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2396941517706172","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42390746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although around 15% of cases are caused by specific genetic causes, most cases involve a complex and variable combination of genetic risk and environmental factors that are not yet identified. There is a paucity of studies on ASD in Qatar, mostly in the form of case reports and genetic causes. The current study was designed to describe the clinical characteristics of ASD and its correlates in Qatar. Individuals with ASD were recruited from the Shafallah Center for Children with Special Needs which is the largest special needs center in Qatar. Within the sample of 171 individuals with ASD, 47% were ethnic Qataris, while 53% were nonethnic Qataris (Arabs and other nationalities). The analysis included the following factors: nationality, age, gender, socioeconomic status, consanguinity, prenatal/postnatal complications, and comorbidities. Eighty percent of the identified cases were males, with a 4:1 male to female ratio. Additionally, 83% of the families had one proband, 9.9% with 2 probands, and 7.1% with more than two. Comorbid conditions included: intellectual disabilities (ID) in 83% and epilepsy in 18.8%. 76.6% of subjects were nonverbal. There were 3 (1.8%) children with Rett’s syndrome, 3 (1.8%) with Fragile X, and 1 (0.6%) with tuberous sclerosis. There are currently no publications that clarify the mean age of diagnosis in Qatar, however, the present study showed that more than half of the diagnosed cases were among the ages of 7–14 years (56%).

In contrast to this view, we recently demonstrated enhanced integration of visual motion signals in autistic children compared to typically developing children. Here, we aimed to investigate the robustness of our finding of increased motion integration in autism with a new sample of children and to determine whether increased integration in autistic children would extend to a static, orientation judgement. Methods We presented motion and orientation equivalent noise and coherence tasks to 46 autistic children aged 6 to 14 years and 45 typically developing children matched in age and non-verbal IQ. The equivalent noise tasks consisted of two interleaved conditions: a high-noise condition in which children judged the average direction or orientation of elements whose range of direction or orientations was manipulated, and a no-noise condition in which children judged the direction or orientation of elements sharing the same direction or orientation. Equivalent noise modelling provided estimates of internal noise (the precision with which children can estimate the orientation/direction of one element) and global sampling (how many elements children are effectively using to judge the overall orientation/direction). Children also completed coherence tasks in which the proportion of signal elements sharing the same direction or orientation amidst otherwise random noise elements was manipulated. We assessed group differences using a combination of frequentist and Bayesian statistical approaches. Results Analysis of the data in this new sample alone did not provide sufficient evidence either in favour or against the hypothesis of increased integration in autism. However, when combining motion data from this and the original experiment, autistic children exhibited superior integration of direction information in the high-noise condition compared to typically developing children, with similar no-noise and coherence thresholds. Equivalent noise modelling of these data revealed increased sampling in autistic children for motion information but no conclusive evidence for atypical levels of internal noise. There was no evidence of differences between autistic and typically developing children in the orientation equivalent noise and coherence tasks. Conclusions Overall, autistic children effectively integrated more direction information than typically developing children. However, the groups overlapped considerably and there was substantial individual variability, so that the effect may be difficult to detect in small groups. There was no indication of atypical integration of orientation in the current study, although larger samples will be required in order to provide conclusive evidence.

Many studies also find that grammar is affected. There are no studies exploring grammar in the Swedish population of children with cochlear implants. Documentation is also sparse regarding if and how language development in children with cochlear implants at the group level has changed over time with for example earlier implantation. The aim of the present study is to explore nonword repetition, grammatical production and sentence comprehension in an older generation of Swedish children with cochlear implants implanted during the 1990s and in a younger generation implanted after 2004. We also wanted to find out if and how nonword repetition is associated with grammatical production and comprehension in the two generations, taking the role of speech perception into consideration. Methods Thirteen adolescents with severe/profound hearing impairment and unilateral cochlear implants, aged 11;9 to 19;1 at the time of testing (age at implant 2;5 to 11;11) and 16 children with severe/profound hearing impairment and cochlear implants, aged 5;3 to 8;0 (age at implant 0;7 to 5;6, ten bilateral) participated. All participants used oral communication. They were tested with nonword repetition and sentence comprehension tasks. Language samples for grammatical analysis were collected during a referential communication task. Transcriptions were analysed with respect to mean length of utterance and grammatical accuracy. Results The two groups performed similar to each other and to reference data from much younger children with normal hearing and language development on nonword repetition. Both groups showed problems in grammatical accuracy. The majority of grammatical errors involved grammatical morphemes. All participants in the older group had significant problems with sentence comprehension, whereas variation was large in the younger group, some children performing at age level. In both groups, nonword repetition was associated with grammatical accuracy and in the younger group also with sentence comprehension. Conclusions Phonological processing skills are significantly hampered in children with cochlear implants, with consequences for language processing and development. Their grammatical problems involve the use of grammatical morphemes, similar to what is found for hearing children with specific language impairment. In spite of early implantation, the results from the younger group indicate that this is still a group at risk for problems with language learning.
