Alterations of tactile processing have long been identified in autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD). However, the extent to which these alterations are disorder-specific, rather than disorder-general, and how they relate to the core symptoms of each disorder, remains unclear. We measured and compared tactile detection, discrimination and order judgment thresholds between a large sample of children with ASD, ADHD, ASD + ADHD combined and typically developing controls. The pattern of results suggested that while difficulties with tactile detection and order judgement were more common in children with ADHD, difficulties with tactile discrimination were more common in children with ASD. Strikingly, subsequent correlation analyses found that the disorder-specific alterations suggested by the group comparisons were also exclusively related to the core symptoms of each respective disorder. These results suggest that disorder-specific alterations of lower-level sensory processes exist and are specifically related to higher-level clinical symptoms of each disorder.

AbstractAlterations of tactile processing have long been identified in autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD). However, the extent to which these alterations are disorder-specific, rather than disorder-general, and how they relate to the core symptoms of each disorder, remains unclear. We measured and compared tactile detection, discrimination, and order judgment thresholds between a large sample of children with ASD, ADHD, ASD + ADHD combined and typically developing controls. The pattern of results suggested that while difficulties with tactile detection and order judgement were more common in children with ADHD, difficulties with tactile discrimination were more common in children with ASD. Interestingly, in our subsequent correlation analyses between tactile perception and disorder-specific clinical symptoms, tactile detection and order judgment correlated exclusively with the core symptoms of ADHD, while tactile discrimination correlated exclusively with the symptoms of ASD. When taken together, these results suggest that disorder-specific alterations of lower-level sensory processes exist and are specifically related to higher-level clinical symptoms of each disorder.

Developmental Stuttering

This descriptive study evaluates the speech disfluencies of 8 verbal children between 3 and 5 years of age with autism spectrum disorders (ASD). Speech samples were collected for each child during standardized interactions. Percentage and types of disfluencies observed during speech samples are discussed. Although they did not have a clinical diagnosis of stuttering, all of the young children with ASD in this study produced disfluencies. In addition to stuttering-like disfluencies and other typical disfluencies, the children with ASD also produced atypical disfluencies, which usually are not observed in children with typically developing speech or developmental stuttering.

Abstract Children with autism spectrum disorders (ASDs), attention deficit hyperactivity disorder (ADHD) and disinhibited and reactive attachment disorders (RAD/DAD) often experience socioemotional problems. Elucidating a clear picture of these profiles is essential. Strengths and Difficulties Questionnaires (SDQs) were analysed from cohort of children with ASD (n = 1430), ADHD (n = 1193), and RAD/DAD (n = 39). Kruskal–Wallis Tests and network analytic techniques were used to investigate symptom profiles. Children with ASD experienced more emotional problems, peer problems and fewer prosocial behaviours. Children with ADHD and RAD/DAD had higher levels of hyperactivity and conduct problems. Overall, ASD and ADHD networks were highly correlated (rs = 0.82), and we did not observe a statistically significant difference in terms of global Strength.

Background: Research on aspects of neurodevelopment such as feeding and swallowing difficulties in children with Autism Spectrum Disorders (ASD) is limited in low and middle income countries such as South Africa. Method: A descriptive comparative group design was used to investigate feeding and swallowing difficulties of young children with ASD in comparison to typically developing peers. The Brief Autism Mealtime Behavioural Inventory (BAMBI) was used. Results: Findings indicated a significant difference in the severity of feeding and swallowing difficulties between the two groups. Difficulties such as food selectivity, sensory processing difficulties, oral-motor difficulties and symptoms of dysphagia were iden- tified. The findings added to the existing global literature on feeding and swallowing difficulties in young children with ASD but provide a unique first perspective on these difficulties in South African children with ASD. Conclusion: Findings also highlighted the use of the BAMBI as an adjunct clinical tool to encourage comprehensive parental report during feeding assessment in this population. Cultural adaptation of the BAMBI for future use in African countries should be considered. A better local understanding of the parental perspective on the multidimensional nature of the feeding and swallowing difficulties displayed by young children with ASD was obtained.

Core Symptoms

: Autism is a neurodevelopmental disorder belonging to the autism spectrum disorder (ASD). In ASDs, the individuals show substantial impairments in social communication, repetitive behaviours, and sensory behaviours deficits in the early stages of their life. Globally, the prevalence of autism is estimated to be less than 1%, especially in high-income countries. In recent decades, there has been a drastic increase in the incidence of ASD, which has put ASD into the category of epidemics. Presently, two US Food and Drug Administration-approved drugs, aripiprazole and risperidone are used to treat symptoms of agitation and irritability in autistic children. However, to date, no medication has been found to treat the core symptoms of ASD. The adverse side effects of conventional medicine and limited treatment options have led families and parents of autistic children to turn to complementary and alternative medicine (CAM) treatments, which are perceived as relatively safe compared to conventional medicine. Recently, N,N-dimethylglycine (DMG), a dietary supplement, has emerged as a useful supplement to improve the mental and physical state of children with ASD. The current review discusses ASD, the prevalence of ASD, CAM approach and efficacy of CAM treatment in children with ASD. Moreover, it highlights the chemistry, pharmacological effect, and clinical studies of DMG, highlighting its potential for improving the lifestyle of children with ASD.

The present study examined whether children with autism spectrum disorder (ASD) and typically developing (TD) children differed in visual perception of food stimuli at both sensorimotor and affective levels. A potential link between visual perception and food neophobia was also investigated. To these aims, 11 children with ASD and 11 TD children were tested. Visual pictures of food were used, and food neophobia was assessed by the parents. Results revealed that children with ASD explored visually longer food stimuli than TD children. Complementary analyses revealed that whereas TD children explored more multiple-item dishes (vs. simple-item dishes), children with ASD explored all the dishes in a similar way. In addition, children with ASD gave more negative appreciation in general. Moreover, hedonic rating was negatively correlated with food neophobia scores in children with ASD, but not in TD children. In sum, we show here that children with ASD have more difficulty than TD children in liking a food when presented visually. Our findings also suggest that a prominent factor that needs to be considered is time management during the food choice process. They also provide new ways of measuring and understanding food neophobia in children with ASD.

Autism spectrum disorders (ASD) include pervasive developmental disorders characterised by communication deficits, difficulty with social understanding, and repetitive behaviors. Few studies have compared the efficacy, affect, and coping strategies of siblings of typically developing children with siblings of children with ASD. Typically developing siblings are understood to be at an increased risk of externalising and internalising problems. The current study examined whether siblings of children with ASD differed in levels of efficacy, affect, and coping from siblings of typically developing children. Participants (156) included an Australia-wide sample involving 82 siblings of children with ASD, and 74 siblings of typically developing individuals. Participants completed The Self-Efficacy Scale for Children (assessing social, emotional, and academic efficacy), the Positive and Negative Affect Scales, the Brief COPE Scale, and other scales as part of the larger study. Results showed that ASD siblings reported lower scores on emotional efficacy, social efficacy, and positive affect, and higher negative affect, than did the comparison group siblings. However, no significant differences were found in coping strategies or academic efficacy between the ASD siblings and the typically developing siblings. Consistent with earlier research findings, there are perceived negative effects or risks from being a sibling of an individual with ASD, suggesting support interventions may assist the development of emotional and social efficacy and increased positive affect for these individuals.

Abstract Contradictory reports of play strengths and weaknesses for children with autism spectrum disorders (ASD) persist in the literature. We compared the play of 19 children with ASD to 19 typically developing (TD) children matched on language and cognitive skills. All children were verbal. Results revealed no differences in indiscriminate actions, functional play, and object interest. The children with ASD showed less symbolic play and a significantly fewer number of children met criteria for emerging or mastered symbolic play. A specific deficit was observed for “doll as agent” symbolic play. Outcomes suggest that compared to children without disabilities, children with ASD may have comparable functional play skills and struggle with the transition to some, but not all types of symbolic play.

ABSTRACTThis study examined two facets of the use of social cues for early word learning in parent–child dyads, where children had an Autism Spectrum Disorder (ASD) or were typically developing. In Experiment 1, we investigated word learning and generalization by children with ASD (age range: 3;01–6;02) and typically developing children (age range: 1;02–4;09) who were matched on language ability. In Experiment 2, we examined verbal and non-verbal parental labeling behaviors. First, we found that both groups were similarly able to learn a novel label using social cues alone, and to generalize this label to other representations of the object. Children who utilized social cues for word learning had higher language levels. Second, we found that parental cues used to introduce object labels were strikingly similar across groups. Moreover, parents in both groups adapted labeling behavior to their child's language level, though this surfaced in different ways across groups.

Object Pronouns

In several languages, including English and Dutch, children’s acquisition of the interpretation of object pronouns (e.g., him) is delayed compared to that of reflexives (e.g., himself). Various syntactic and pragmatic explanations have been proposed to account for this delay in children’s acquisition of pronoun interpretation. This study aims to provide more insight into this delay by investigating potential cognitive mechanisms underlying this delay. Dutch-speaking children between 6 and 12 years old with autism spectrum disorder (ASD; n = 47), attention-deficit/hyperactivity disorder (ADHD; n = 36) or typical development (TD; n = 38) were tested on their interpretation and production of object pronouns and reflexives and on theory of mind, working memory, and response inhibition. It was found that all three groups of children had difficulty with pronoun interpretation and that their performance on pronoun interpretation was associated with theory of mind and inhibition. These findings support an explanation of object pronoun interpretation in terms of perspective taking, according to which listeners need to consider the speaker’s perspective in order to block coreference between the object pronoun and the subject of the same sentence. Unlike what is predicted by alternative theoretical accounts, performance on pronoun interpretation was not associated with working memory, and the children made virtually no errors in their production of object pronouns. As the difficulties with pronoun interpretation were similar for children with ASD, children with ADHD and typically developing children, this suggests that certain types of perspective taking are unaffected in children with ASD and ADHD.
