Absence of sex differences in mental rotation performance in autism spectrum disorder / M. S. ROHDE in Autism, 22-7 (October 2018)
[article]
Titre : Absence of sex differences in mental rotation performance in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : M. S. ROHDE, Auteur ; Alexandra Livia GEORGESCU, Auteur ; Kai VOGELEY, Auteur ; R. FIMMERS, Auteur ; C. M. FALTER-WAGNER, Auteur Article en page(s) : p.855-865 Langues : Anglais (eng) Mots-clés : adults autism spectrum disorders extreme male brain mental rotation sex differences visuo-spatial Index. décimale : PER Périodiques Résumé : Mental rotation is one of the most investigated cognitive functions showing consistent sex differences. The 'Extreme Male Brain' hypothesis attributes the cognitive profile of individuals with autism spectrum disorder to an extreme version of the male cognitive profile. Previous investigations focused almost exclusively on males with autism spectrum disorder with only limited implications for affected females. This study is the first testing a sample of 12 female adults with high-functioning autism spectrum disorder compared to 14 males with autism spectrum disorder, 12 typically developing females and 14 typically developing males employing a computerised version of the mental rotation test. Reaction time and accuracy served as dependent variables. Their linear relationship with degree of rotation allows separation of rotational aspects of the task, indicated by slopes of the psychometric function, and non-rotational aspects, indicated by intercepts of the psychometric function. While the typical and expected sex difference for rotational task aspects was corroborated in typically developing individuals, no comparable sex difference was found in autism spectrum disorder individuals. Autism spectrum disorder and typically developing individuals did not differ in mental rotation performance. This finding does not support the extreme male brain hypothesis of autism.

[article]
Titre : Gender differences in mental rotation strategy depend on degree of autistic traits Type de document : Texte imprimé et/ou numérique Auteurs : J. L. STEVENSON, Auteur ; M. B. NONACK, Auteur Article en page(s) : p.1024-1037 Langues : Anglais (eng) Mots-clés : Autistic traits eye movements gender differences mental rotation visual spatial skills Index. décimale : PER Périodiques Résumé : Participants with low, medium, and high autistic traits completed a mental rotation task while their eye movements were recorded. Men were more accurate than women (F(1, 102) = 4.36, P = 0.04, eta(2)p = 0.04), but there were no group differences in reaction time. In terms of eye movements, all participants tended to rely on top corners of cube figures for most angles of rotation, and bottom corners of cube figures for 0 and 90 degree rotations (duration: F(8, 816) = 21.70, P < 0.001, eta(2)p = 0.18; count: F(8, 816) = 24.42, P < 0.001, eta(2)p = 0.19) suggesting a shift in strategy with rotation angle. Eye movements to corners of cube figures also varied by autistic traits group and gender (duration: F(4, 204) = 2.44, P = 0.05, eta(2)p = 0.05; count: F(4, 204) = 2.47, P = 0.05, eta(2)p = 0.05). Participants with low and medium autistic traits tended to rely more often on the top corners, whereas women with high autistic traits relied on both the top and bottom corners and men with high autistic traits relied on all corners equally. These results suggest mental rotation strategies may vary by both gender and autistic traits. Autism Res 2018, 11: 1024-1037. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The current study looked at eye movements to assess adults' strategies when mentally rotating three-dimensional cube figures. Adults with varying levels of autistic traits differ in their mental rotation strategies. In addition, gender differences in strategies are observed in adults with the highest level of autistic traits.

BOWLER, Auteur Article en page(s) : p.2101-2111 Langues : Anglais (eng) Mots-clés : Allocentric Autism spectrum disorder Egocentric Mental rotation Spatial navigation Task support hypothesis Visual short-term memory Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) present difficulties in forming relations among items and context. This capacity for relational binding is also involved in spatial navigation and research on this topic in ASD is scarce and inconclusive. Using a computerised version of the Morris Water Maze task, ASD participants showed particular difficulties in performing viewpoint independent (allocentric) navigation, leaving viewpoint dependent navigation (egocentric) intact. Further analyses showed that navigation deficits were not related to poor visual short-term memory or mental rotation in the ASD group. The results further confirm the need of autistic individuals for support at retrieval and have important implications for the design of signposts and maps.

Given the extensive evidence suggesting ASDs are characterized by abnormal neural connectivity, this study aimed to investigate network connectivity during visuospatial processing in ASD. Twenty-two males with ASD without intellectual disability and 22 individually matched controls performed a mental rotation task during functional magnetic resonance imaging (MRI) in which two rotated stimuli were judged to be same (“Same Trials”) or mirror-imaged (“Mirror Trials”). Behavioral results revealed a relative advantage of mental rotation in the ASD group—controls were slower responding to the more difficult Mirror Trials than Same Trials whereas the ASD group completed Mirror Trials and Same-trials at similar speeds. In the ASD group, brain activity was reduced in frontal, temporal, occipital, striatal, and cerebellar regions and, consistent with previous literature, functional connectivity between a number of brain regions was reduced. However, some connections appeared to be conserved and were recruited in a qualitatively different way by the two groups. As task difficulty increased (on Mirror Trials), controls tended to increase connections between certain brain regions, whereas the ASD group appeared to suppress connections between these regions. There was an interesting exception to this pattern in the visual cortex, a finding that may suggest an advantage in early visual perceptual processing in ASD. Overall, this study has identified a relative advantage in mental rotation in ASD that is associated with aberrant neural connectivity and that may stem from enhanced visual perceptual processing.

Titre : Cognitive Mechanisms underlying visual perspective taking in typical and ASC children Type de document : Texte imprimé et/ou numérique Auteurs : Amy PEARSON, Auteur ; Lauren MARSH, Auteur ; Danielle ROPAR, Auteur ; Antonia HAMILTON, Auteur Article en page(s) : p.121-130 Langues : Anglais (eng) Mots-clés : autism spectrum conditions visual perspective taking mental rotation embodied cognitive mechanisms Index. décimale : PER Périodiques Résumé : Previous research has suggested that people with Autism Spectrum Conditions (ASC) may have difficulty with visual perspective taking (VPT) but it is not clear how this relates to different strategies that can be used in perspective taking tasks. The current study examined VPT in 30 children with autism and 30 verbal mental age matched typical children, in comparison to mental rotation (MR) abilities and body representation abilities. Using a similar paradigm to Hamilton, Brindley, and Frith [2009] all children completed three tasks: a VPT task in which children decided what a toy on a table would look like from a different points of view; a MR task in which the child decided what a toy would look like after it had been rotated; and a body posture matching task, in which children matched pictures of a body shown from different viewpoints. Results showed that children with ASC performed better than the typically developing children on the MR task, and at a similar level on the VPT task and body matching task. Importantly, in the typical children VPT performance was predicted by performance on the body matching task, whereas in the ASC children VPT performance was predicted by MR ability. These findings suggest that differences in VPT in ASC may be explained by the use of a spatial rotation strategy rather than the embodied egocentric transformation strategy used by typical children.
