Topographic differences of slow event-related brain potentials in blind and sighted adult human subjects during haptic mental rotation / Frank ROSLER in Cognitive Brain Research, 1-3 (October 1993)

Public ISBD [article]  inCognitive Brain Research > 1-3 (October 1993) . - p.145-159 Titre : Topographic differences of slow event-related brain potentials in blind and sighted adult human subjects during haptic mental rotation Type de document : texte imprimé Auteurs : Frank ROSLER, Auteur ; Brigitte RODER, Auteur ; Martin HEIL, Auteur ; Erwin HENNIGHAUSEN, Auteur Année de publication : 1993 Article en page(s) : p.145-159 Langues : Anglais (eng) Mots-clés : Blindness Electroencephalogram Slow-wave Functional-organization-of-the-cortex Cortical-plasticity Haptic-mental-rotation Cognition Index. décimale : PER Périodiques Résumé : Twelve blindfolded sighted, nine congenitally blind, and seven adventitiously blind subjects were tested in a haptic mental rotation task while slow event-related potentials in the EEG were recorded from 17 scalp locations. The overall topography of the slow wave pattern which prevailed during the task differed for sighted and for blind, but not for congenitally and adventitiously blind subjects. While the tactile stimuli were encoded, the blind showed a pronounced occipital and the sighted a pronounced frontal activation. The task-specific amplitude increment of a negative slow wave which can be understood as a manifestation of the process of mental rotation proper, showed a different topography for sighted and for blind subjects too. It had its maximum over central to parietal cortical areas in both groups, but it extended more towards occipital regions in the blind. In both groups, the effects were very similar to those observed in former studies with visual versions of the mental rotation task, i.e. the slow wave amplitude over central to parietal areas increased monotonously with an increasing angular disparity of the two stimuli to be compared. These results are discussed with respect to the question of whether visual deprivation in the blind can cause a reorganization of cortical representational maps.

Absence of sex differences in mental rotation performance in autism spectrum disorder / Melanie S. ROHDE in Autism, 22-7 (October 2018)  

Public ISBD [article]  inAutism > 22-7 (October 2018) . - p.855-865 Titre : Absence of sex differences in mental rotation performance in autism spectrum disorder Type de document : texte imprimé Auteurs : Melanie S. ROHDE, Auteur ; Alexandra Livia GEORGESCU, Auteur ; Kai VOGELEY, Auteur ; Rolf FIMMERS, Auteur ; Christine 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.

Allocentric Versus Egocentric Spatial Memory in Adults with Autism Spectrum Disorder / Melanie RING in Journal of Autism and Developmental Disorders, 48-6 (June 2018)

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.

Atypical Visuospatial Processing in Autism: Insights from Functional Connectivity Analysis / Jane MCGRATH in Autism Research, 5-5 (October 2012)  

Public ISBD [article]  inAutism Research > 5-5 (October 2012) . - p.314-330 Titre : Atypical Visuospatial Processing in Autism: Insights from Functional Connectivity Analysis Type de document : texte imprimé Auteurs : Jane MCGRATH, Auteur ; Katherine A.

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.

Cognitive Mechanisms underlying visual perspective taking in typical and ASC children / Amy PEARSON in Autism Research, 9-1 (January 2016)  

Public ISBD [article]  inAutism Research > 9-1 (January 2016) . - p.121-130 Titre : Cognitive Mechanisms underlying visual perspective taking in typical and ASC children Type de document : texte imprimé 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.
