Evidence for a Cultural Influence on Field-Independence in Autism Spectrum Disorder / Hwan CUI KOH in Journal of Autism and Developmental Disorders, 42-2 (February 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-2 (February 2012) . - p.181-190 Titre : Evidence for a Cultural Influence on Field-Independence in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Hwan CUI KOH, Auteur ; Elizabeth MILNE, Auteur Année de publication : 2012 Article en page(s) : p.181-190 Langues : Anglais (eng) Mots-clés : Perceptual style  Weak central coherence  Culture  Autism spectrum disorders Index. décimale : PER Périodiques Résumé : Field-independence, or weak central coherence, is a recognised phenotype of autism spectrum disorder (ASD). There is also evidence of cultural variation in this perceptual style, as neurotypical individuals from Western nations are more field-independent than neurotypical individuals from East-Asian nations. The majority of research on perceptual style in those with ASD has been carried out in Western nations therefore it is unclear whether increased field-independence in ASD is a culturally universal phenotype. Here, we assessed perceptual style in children with and without ASD from England and Singapore using the Children’s Embedded Figures Test and the Framed-Line Test. We found increased field-independence in the English participants with ASD only, suggesting that weak central coherence in ASD is not culturally universal.

Linking the Puzzle Pieces of the Past: A Study of Relational Memory in Children with Autism Spectrum Disorder / Rasmine L. H. MOGENSEN in Autism Research, 13-11 (November 2020)  

Public ISBD [article]  inAutism Research > 13-11 (November 2020) . - p.1959-1969 Titre : Linking the Puzzle Pieces of the Past: A Study of Relational Memory in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Rasmine L. H. MOGENSEN, Auteur ; Maja B. HEDEGAARD, Auteur ; Ludvig R. OLSEN, Auteur ; Line GEBAUER, Auteur Article en page(s) : p.1959-1969 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  executive functions  memory  memory binding  perceptual style  relational memory Index. décimale : PER Périodiques Résumé : Our memories are made of detailed sensory information representing the puzzle pieces of our personal past. The type of memory integrating sensory features is referred to as relational memory. The main objective of this study was to investigate whether relational memory is affected in children with autism spectrum disorder (ASD) since altered relational memory may contribute to atypical episodic memory observed in ASD. We also examined the association between perceptual style and relational memory abilities. Children with ASD (n = 14) and typically developed (TD) children (n = 16, 9-15?years old) completed a memory task with three conditions: two single-feature conditions measuring memory for objects and locations, and one relational memory condition measuring memory for objects and their locations combined. The Children's embedded figures test was administered to measure perceptual style. The ASD group selected more incorrect stimuli (false alarms) than the TD group, resulting in a lower proportion of correctly recognized targets across all memory conditions. The ASD group did not display a more local perceptual style than the TD group. However, perceptual style was associated with improved memory abilities across conditions. Our findings indicate that the overall memory performance of children with ASD is less stable, leading them to more incorrect responses than TD children. This may be due to the executive demands of the memory tasks, rather than specific impairments in memory binding. Autism Res 2020, 13: 1959-1969. © 2020 International Society for Autism Research and Wiley Periodicals LLC LAY SUMMARY: The present study shows that children with autism have a less stable memory than typically developed children, which is reflected in a higher amount of incorrect memory responses. Overall, our results indicate that children with autism display difficulties in differentiating previously studied from novel information when solving both single-feature memory tasks and a relational memory task (requiring memory of combination of features). These difficulties may have implications for how children with autism remember episodes from their personal past.

Figure Disembedding: The Gottschaldt's Hidden Figure Test in Children with Typical Development and Autism / Massimiliano CONSON in Journal of Autism and Developmental Disorders, 52-9 (September 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-9 (September 2022) . - p.3790-3799 Titre : Figure Disembedding: The Gottschaldt's Hidden Figure Test in Children with Typical Development and Autism Type de document : Texte imprimé et/ou numérique Auteurs : Massimiliano CONSON, Auteur ; Mattia SICILIANO, Auteur ; Luigi TROJANO, Auteur ; Pierluigi ZOCCOLOTTI, Auteur ; Isa ZAPPULLO, Auteur ; Chiara BAIANO, Auteur ; Giovanni CAPUTO, Auteur ; Alessandro RUSSO, Auteur ; LABNPEE GROUP, Auteur ; Gabriella SANTANGELO, Auteur Article en page(s) : p.3790-3799 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/psychology  Autistic Disorder/diagnosis  Child  Humans  Figure disembedding  Hidden figures  Perception of details  Perceptual style Index. décimale : PER Périodiques Résumé : In two studies, we used the Gottschaldt's Hidden Figure Test (GHFT) for assessing figure disembedding ability in children aged 7-11. Study 1 demonstrated in a large sample of typically developing children that GHFT accuracy and time scores differed across age groups, without sex and socioeconomic differences. Thus, we provided normative data only taking into account children's age. In Study 2, GHFT normative values were used to assess children with autism, who were also compared with a closely age-matched group of typical controls. Children with autism achieved time scores at or above the 50th centile and significantly differed from the controls for time score. The GHFT seems a valuable tool for defining the cognitive profile of children with autism.
