Altered bodily self-consciousness and peripersonal space in autism / Cari-Lène MUL in Autism, 23-8 (November 2019)  

Public ISBD [article]  inAutism > 23-8 (November 2019) . - p.2055-2067 Titre : Altered bodily self-consciousness and peripersonal space in autism Type de document : texte imprimé Auteurs : Cari-Lène MUL, Auteur ; Flavia CARDINI, Auteur ; Steven D. STAGG, Auteur ; Shabnam SADEGHI ESFAHLANI, Auteur ; Dimitrios KIOURTSOGLOU, Auteur ; Pasquale CARDELLICCHIO, Auteur ; Jane E. ASPELL, Auteur Article en page(s) : p.2055-2067 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  bodily self-consciousness  full body illusion  multisensory integration  peripersonal space Index. décimale : PER Périodiques Résumé : There is some evidence that disordered self-processing in autism spectrum disorders is linked to the social impairments characteristic of the condition. To investigate whether bodily self-consciousness is altered in autism spectrum disorders as a result of multisensory processing differences, we tested responses to the full body illusion and measured peripersonal space in 22 adults with autism spectrum disorders and 29 neurotypical adults. In the full body illusion set-up, participants wore a head-mounted display showing a view of their 'virtual body' being stroked synchronously or asynchronously with respect to felt stroking on their back. After stroking, we measured the drift in perceived self-location and self-identification with the virtual body. To assess the peripersonal space boundary we employed an audiotactile reaction time task. The results showed that participants with autism spectrum disorders are markedly less susceptible to the full body illusion, not demonstrating the illusory self-identification and self-location drift. Strength of self-identification was negatively correlated with severity of autistic traits and contributed positively to empathy scores. The results also demonstrated a significantly smaller peripersonal space, with a sharper (steeper) boundary, in autism spectrum disorders participants. These results suggest that bodily self-consciousness is altered in participants with autism spectrum disorders due to differences in multisensory integration, and this may be linked to deficits in social functioning.

Episodic Future Thinking in Autism Spectrum Disorder and 22q11.2 Deletion Syndrome: Association with Anticipatory Pleasure and Social Functioning / Clémence FELLER in Journal of Autism and Developmental Disorders, 51-12 (December 2021)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 51-12 (December 2021) . - p.4587-4604 Titre : Episodic Future Thinking in Autism Spectrum Disorder and 22q11.2 Deletion Syndrome: Association with Anticipatory Pleasure and Social Functioning Type de document : texte imprimé Auteurs : Clémence FELLER, Auteur ; Charlotte DUBOIS, Auteur ; Stephan ELIEZ, Auteur ; Maude SCHNEIDER, Auteur Article en page(s) : p.4587-4604 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  DiGeorge Syndrome  Humans  Memory, Episodic  Mental Recall  Pleasure  Social Interaction  22q11.2 deletion syndrome  Anticipatory pleasure  Autism spectrum disorder  Autonoetic consciousness  Episodic future thinking  Social functioning Index. décimale : PER Périodiques Résumé : Episodic future thinking (EFT) has been suggested to underlie anticipatory pleasure (AP), itself known to play a crucial role in social functioning (SF). Both AP and SF are impaired in various clinical populations, including autism spectrum disorders (ASD) and 22q11.2 deletion syndrome (22q11DS). Therefore, the relationship between EFT, AP and SF was investigated, as well as the potential role of projecting oneself in a social vs. non-social context. Seventy-seven participants [24 with 22q11DS, 20 with ASD, 33 typically developing controls (TDs)] (aged 12-25) were included. They were assessed with a future thinking task in which they were asked to recall a memory and produce a likely event. Narratives were rated based of specificity, richness and imaginability. Participants completed questionnaires assessing AP and SF. Narratives from ASD and 22q11DS participants were rated as less vivid compared to TDs. However, the characteristics of the narratives differed between ASD and 22q11DS participants in terms of specificity and level of details, as well as in reaction to social condition. Moreover, correlations were found between AP and EFT in both ASD and 22q11DS participants, and between SF and EFT in ASD participants. These results point towards impairments in EFT in both ASD and 22q11DS participants but with a specific profile in each condition. The observed associations between EFT and AP suggest that decreased autonoetic consciousness might underlie AP impairments. In ASD individuals, the association between SF and EFT highlights the need to better characterize EFT since EFT could be another mechanism contributing to social difficulties.

Episodic memory and self-awareness in Asperger Syndrome: Analysis of memory narratives / Valérie CHAPUT in Research in Autism Spectrum Disorders, 7-9 (September 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-9 (September 2013) . - p.1062-1067 Titre : Episodic memory and self-awareness in Asperger Syndrome: Analysis of memory narratives Type de document : texte imprimé Auteurs : Valérie CHAPUT, Auteur ; Frédérique AMSELLEM, Auteur ; Isabel URDAPILLETA, Auteur ; Pauline CHASTE, Auteur ; Marion LEBOYER, Auteur ; Richard DELORME, Auteur ; Véronique GOUSSE, Auteur Article en page(s) : p.1062-1067 Langues : Anglais (eng) Mots-clés : Episodic memory  Asperger Syndrome  Self-awareness  Autonoetic consciousness  Theory of mind Index. décimale : PER Périodiques Résumé : Abstract Previous findings from researchers on individuals with Asperger Syndrome (AS) suggest peculiarities of autobiographical memory (AM). They have shown a personal episodic memory deficit in the absence of a personal semantic memory impairment. The primary aim of this study was to explore AM in individuals with AS, and more specifically to investigate the link between episodic memory, self-awareness, and autonoetic consciousness through language analysis. We asked fifteen adults with AS and fifteen age- and IQ-matched controls to recall autobiographical memories from three life periods. Recorded interviews were processed using Alceste software. We found that participants with AS recalled fewer and less-detailed episodic memories than did controls. A content analysis revealed that family-related vocabulary as well as possessive pronouns was significantly less frequent in AS interviews than in those of controls. In conclusion, our results support the hypothesis that a deficiency of episodic memory may be due to poor awareness of the self in social relationships. Reduced use of possessive pronouns may also indicate less self-investment in life experiences, which would in turn impact recall.

Imaginary companions and young children's responses to ambiguous auditory stimuli: implications for typical and atypical development / Charles FERNYHOUGH in Journal of Child Psychology and Psychiatry, 48-11 (November 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-11 (November 2007) . - p.1094–1101 Titre : Imaginary companions and young children's responses to ambiguous auditory stimuli: implications for typical and atypical development Type de document : texte imprimé Auteurs : Charles FERNYHOUGH, Auteur ; Kirsten BLAND, Auteur ; Elizabeth MEINS, Auteur ; Max COLTHEART, Auteur Année de publication : 2007 Article en page(s) : p.1094–1101 Langues : Anglais (eng) Mots-clés : Imaginary-companions hallucinations childhood theory-of-mind stream-of-consciousness Index. décimale : PER Périodiques Résumé : Previous research has reported a link between imaginary companions (ICs) in middle childhood and the perception of verbal material in ambiguous auditory stimuli. These findings have been interpreted in terms of commonalities in the cognitive processes underlying children's engagement with ICs and adults’ reporting of imaginary verbal experiences such as auditory verbal hallucinations. The aim of the present study was to examine these relations using improved methodology and a younger sample of children for whom engagement with ICs would be expected to be particularly salient. Method: Data on young children's (age range: 4–8 years) reporting of ICs were gathered in two studies (total N = 80). Responses to ambiguous auditory stimuli were investigated using the new Jumbled Speech task, which measures participants’ likelihood of perceiving words in meaningless but speech-like auditory stimuli. Results: Reporting hearing words in the Jumbled Speech task was associated with having a parentally corroborated IC. Hearing words on the task and having an IC were unrelated to age, gender, verbal ability, and understanding of the stream of consciousness. Conclusions: Findings are consistent with the hypothesis that engaging with ICs is one aspect of a general susceptibility to imaginary verbal experiences. We consider the implications for the assumption of continuity in psychopathological experiences between childhood and adulthood.

A lack of self-consciousness in Asperger's disorder but not in PDDNOS: Implication for the clinical importance of ASD subtypes / Sayaka YOSHIMURA in Research in Autism Spectrum Disorders, 8-3 (March 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-3 (March 2014) . - p.237-243 Titre : A lack of self-consciousness in Asperger's disorder but not in PDDNOS: Implication for the clinical importance of ASD subtypes Type de document : texte imprimé Auteurs : Sayaka YOSHIMURA, Auteur ; Motomi TOICHI, Auteur Article en page(s) : p.237-243 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD)  Subtyping  Self-consciousness  Self-information processing  Memory Index. décimale : PER Périodiques Résumé : Abstract Self-consciousness plays an important role in a person's social life. Assuming that self-consciousness is a key to understanding social impairments in high-functioning autism spectrum disorder (ASD), we examined self-consciousness in individuals with Asperger's disorder, pervasive developmental disorder not otherwise specified (PDDNOS) and their controls using an episodic memory task. The PDDNOS group consisted of individuals in a milder subgroup of PDDNOS, with less autistic features than Asperger's disorder. In the learning phase, one of three types of questions (phonological, semantic, self-referential) was asked about each following target word. The target words were all personality trait adjectives. Next, a recognition test was conducted. The PDDNOS group, like the control, showed the most superior performance in self-referential processing (i.e. the self-reference effect) while the Asperger's group did not; however, both the ASD groups revealed an atypical pattern of relationship between memory performance and IQ. Individuals with PDDNOS, unlike those with Asperger's disorder, may be self-conscious to the same degree as typically developing individuals, but the cognitive process leading them to self-consciousness seems atypical, causing social impairments similar to those seen in individuals with Asperger's disorder who lack self-consciousness.
