Seeing the funny side of things: Humour processing in Autism Spectrum Disorders / Catarina SILVA in Research in Autism Spectrum Disorders, 43-44 (November 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 43-44 (November 2017) . - p.8-17 Titre : Seeing the funny side of things: Humour processing in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Catarina SILVA, Auteur ; David DA FONSECA, Auteur ; Francisco ESTEVES, Auteur ; Christine DERUELLE, Auteur Article en page(s) : p.8-17 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Humour processing  Humour appreciation  Social reward  Social motivation Index. décimale : PER Périodiques Résumé : AbstractBackground Humour is fundamentally a social phenomenon, occurring frequently in social and playful contexts. The positive affect resulting from an experience of enjoyed humour makes it socially rewarding. A lack of sense of humour has been associated with individuals with autism spectrum disorders (ASD), however, the existing literature is sparse and inconclusive. In this study, we investigated implicit and explicit humour understanding and appreciation in ASD. Method Specifically, an implicit item-item associative task was used, in which participants saw neutral-humorous and neutral-neutral sequences of two pictures in an encoding phase. Following a filler task, sequence recognition was measured in a yes/no test phase. At the end of the task, explicit measures of humour understanding and appreciation were completed by the participants, who rated the picture sequences for humour appreciation and funniness. Results Results revealed that, at an explicit level, participants with ASD were able to enjoy and understand the humorous stimuli as much as typically developing (TD) participants. At an implicit level, however, the results suggest that humour processing may be specially content-dependent in ASD. Fine-grained analysis on task performance indeed showed an altered humorous processing for social, but not for non-social humorous content in the ASD group, while that was not the case for the TD group. Conclusions These results suggest that participants with ASD may be distinctively motivated to attend to social reward cues such as social humorous stimuli. These findings are discussed within the social motivation hypothesis framework.

Mind-mindedness in mothers of children with autism spectrum disorder / Elizabeth KIRK in Research in Autism Spectrum Disorders, 43-44 (November 2017)

Previous research has shown that being mind-minded can limit the experience of parenting stress in typically developing samples. The current study explored mind-mindedness in mothers of children with autism spectrum disorder (ASD) and examined whether this related to the experience of parenting stress. Method Mind-mindedness was coded from mothers’ descriptions of their child obtained from an online survey (N = 55). A subsample of these mothers also provided data on a non-ASD sibling (n = 27). We compared mothers’ mind-mindedness when describing their child with ASD and a non-ASD sibling. Results Mothers predominantly described their child with ASD using mental and behavioral attributes. There were no overall differences in mothers’ use of mental state descriptors when referring to their child with ASD or a sibling, however, when considering the valence of descriptors, a significantly higher proportion of the mental attributes used to describe the child with ASD were negative. Associations between mind-mindedness and overall parenting stress failed to reach significance. Conclusions Parenting a child with ASD does not appear to limit the parent’s ability to tune-in to their child’s mind. Maternal mind-mindedness scores were similar for the ASD and non-ASD sibling, although there were differences in the valence of representations. Being mind-minded did not protect against parenting stress, however we suggest that the high levels of stress experienced by our sample were beyond the protective reach of mind-mindedness.

Difficulties with dialogue may reflect impairment in interpersonal engagement more than general language ability. Method We investigated conversational abilities among children and adolescents with and without autism (n = 18 per group) matched for language proficiency and productivity. Videotaped conversations from the Autism Diagnostic Observational Schedule (ADOS, Lord, Rutter, DiLavore, & Risi, 2001) were rated according to the Collaborative Competence in Dialogue (CCD) scale featuring six verbal and non-verbal ‘cues’ that conversational partners use to sustain dialogue. Results Participants with autism produced significantly fewer ‘typical’ communicative cues and more cues rated as intermittent or rote/stereotyped, even when non-verbal items (gaze) were removed from consideration. Within the autism group, competence in dialogue was not correlated with ‘general’ language ability, but was correlated with a measure of pragmatic ability. Conclusions Difficulties with collaboration in dialogue may mirror the intermittent or incomplete interpersonal engagement of children with autism. Implications Assessment of language ability in autism should include observation in unstructured social settings.

Evidence of hyper-plasticity in adults with Autism Spectrum Disorder / J. F. WILSON in Research in Autism Spectrum Disorders, 43-44 (November 2017)

HAMM, Auteur Article en page(s) : p.40-52 Langues : Anglais (eng) Mots-clés : Long-term potentiation  Autism spectrum disorder  Plasticity  Visual evoked potentials  EEG Index. décimale : PER Périodiques Résumé : AbstractBackground Long-term potentiation (LTP) is a form of synaptic plasticity involved in learning and memory. Abnormal levels of LTP have been suggested to contribute to symptoms in a number of disorders, and here we examined the extent to which LTP may be affected in autism spectrum disorders (ASD). While animal models of ASD have suggested LTP may be atypical, the results have been inconsistent in terms of the direction of abnormality. Method In the present study a paradigm for non-invasively eliciting LTP in humans was utilized to test a group of adults with ASD and matched controls. This paradigm uses high-frequency visual stimulation as the LTP-inducing stimulus, and the effect of LTP is reflected by an increase in amplitude of the visually-elicited N1b component of the visual evoked potential (VEP). Result Main effects for Hemisphere and Tetanus were found. While Group interactions were not found, a Group by Tetanus interaction was approaching significance and was determined to be weak evidence against the null ((pH0|D = 0.44) therefore, LTP effects were explored within groups for the N1 component. It was found that the ASD group had a greater N1 amplitude compared to controls. Conclusion Our results showed that the ASD group had greater N1 amplitude post-tetanus over the right hemisphere compared to controls and demonstrate elevated LTP. These results support the notion of enhanced perceptual functioning, as elevated LTP may be related to superior visual processing due to overspecialised neural networks in ASD.

Method Profiles were compared to a sample of children with non-ASD developmental delays. Cluster analyses were performed to determine whether differences in adaptive skills effectively distinguished children with ASD from other young children presenting for assessment due to behavioral or other concerns, but who received other non-ASD diagnoses. Results A profile of motor > daily living > socialization > communication skills was found in both children with ASD and children with non-spectrum diagnoses, showing that this profile is not unique to young children with ASD. A two-group cluster solution was found which differentiated children by developmental functioning level rather than by diagnosis. Discussion The results of this study provide support for two developmental profiles for adaptive functioning in children with ASD: an average to borderline delayed profile and a borderline to more severely delayed profile that may remain stable or worsen over time. They additionally highlight the importance of delivering early targeted interventions to children with ASD who have greater deficits in adaptive functioning due to their association with poorer long-term outcomes.

There are few studies considering its efficacy in adults and those that exist usually compare it to standard treatment, as opposed to controlling for non-specific improvements that may result from receiving an intervention. We conducted a pilot study to investigate whether social skills training is more effective than non-specific support for adults with ASD. Methods 19 adults with ASD were randomised to either social skills training or non-specific social interaction groups for 16 weeks. The Reading the Mind in the Eyes and Reading the Mind in the Voice Tasks were used to assess social cognition while the Social Responsiveness Scale (SRS-2) and the Weiss Functional Impairment Rating Scale (WFIRS-S) were used to measure real-life change pre- and post-treatment. Results Taken together, both groups improved across the course of the study on the ‘Eyes’ task (p = 0.049), SRS-2 (p = 0.03) and WFIRS-S (p = 0.053). However, there were no significant differences between the groups. There was some trend-level evidence that the social skills group improved more on the tests of social cognition (p ? 0.1 for group x time interaction). This was not the case for the SRS-2 (p = 0.25) and for the WFIRS-S there was a trend for the social interaction group to show greater improvements (p = 0.07). Conclusions This study did not show clear evidence of benefit from social skills training compared to facilitated social interaction, although larger studies are required to draw firm conclusions about efficacy.

Decreased interhemispheric time transfer of visual information in adults with Autistic spectrum disorder using the Poffenberger paradigm / Veema LODHIA in Research in Autism Spectrum Disorders, 43-44 (November 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 43-44 (November 2017) . - p.76-86 Titre : Decreased interhemispheric time transfer of visual information in adults with Autistic spectrum disorder using the Poffenberger paradigm Type de document : Texte imprimé et/ou numérique Auteurs : Veema LODHIA, Auteur ; Curie J. SUK, Auteur ; Vanessa LIM, Auteur ; Jeff P. HAMM, Auteur ; Ian J. KIRK, Auteur Article en page(s) : p.76-86 Langues : Anglais (eng) Mots-clés : Autistic spectrum disorders  Corpus callosum  Interhemispheric time transfer  Event-related potentials  Poffenberger  Electroencephalography Index. décimale : PER Périodiques Résumé : AbstractBackground The Poffenberger task is a useful paradigm that measures the interhemispheric transfer time (IHTT) across the corpus callosum. Past research has demonstrated that the right to left transfer is faster in typically developing individuals compared to a left to right transfer. Numerous studies have found that the corpus callosum is structurally smaller and atypical in individuals with Autistic spectrum disorder (ASD) but whether this is associated with changes in interhemispheric time transfer in adult individuals with ASD is relatively unknown. Method The current study used a Poffenberger paradigm in combination with electroencephalography (EEG) to measure IHTT between individuals with ASD and typically developing controls. The IHTT in each direction was estimated by comparing the latencies of P100 and N170 components in hemispheres contralateral and ipsilateral to lateralised visual stimulation. Results Both groups demonstrated faster right to left transfer of information compared to the left to right transmission. Individuals with ASD exhibited faster IHTT latencies overall for the P100 and N170 components compared to matched typically developing controls. More importantly, these results demonstrate that the ASD group exhibited faster transfer in both directions compared to matched typically developing controls. Conclusion These findings suggest hyper-connectivity of local networks in parietal and occipital regions of the corpus callosum in ASD and may have implications in how information is integrated between hemispheres in ASD.

Past research has demonstrated that the right to left transfer is faster in typically developing individuals compared to a left to right transfer. Numerous studies have found that the corpus callosum is structurally smaller and atypical in individuals with Autistic spectrum disorder (ASD) but whether this is associated with changes in interhemispheric time transfer in adult individuals with ASD is relatively unknown. Method The current study used a Poffenberger paradigm in combination with electroencephalography (EEG) to measure IHTT between individuals with ASD and typically developing controls. The IHTT in each direction was estimated by comparing the latencies of P100 and N170 components in hemispheres contralateral and ipsilateral to lateralised visual stimulation. Results Both groups demonstrated faster right to left transfer of information compared to the left to right transmission. Individuals with ASD exhibited faster IHTT latencies overall for the P100 and N170 components compared to matched typically developing controls. More importantly, these results demonstrate that the ASD group exhibited faster transfer in both directions compared to matched typically developing controls. Conclusion These findings suggest hyper-connectivity of local networks in parietal and occipital regions of the corpus callosum in ASD and may have implications in how information is integrated between hemispheres in ASD.
