Digit Ratio 2D:4D in Relation to Autism Spectrum Disorders, Empathizing, and Systemizing: A Quantitative Review / Johannes HONEKOPP in Autism Research, 5-4 (August 2012)  

Public ISBD [article]  inAutism Research > 5-4 (August 2012) . - p.221-30 Titre : Digit Ratio 2D:4D in Relation to Autism Spectrum Disorders, Empathizing, and Systemizing: A Quantitative Review Type de document : Texte imprimé et/ou numérique Auteurs : Johannes HONEKOPP, Auteur Année de publication : 2012 Article en page(s) : p.221-30 Langues : Anglais (eng) Mots-clés : autism  digit ratio  prenatal testosterone  empathizing  systemizing  sex differences Index. décimale : PER Périodiques Résumé : Prenatal testosterone (PT) effects have been proposed to increase systemizing (the drive to understand lawful input–output relationships), to decrease empathizing (the drive to understand others), and to cause autism via hypermasculinization of the brain. Digit ratio 2D:4D is a putative marker of PT effects in humans. An online study (n = 1896) into the relationship between the Reading the Mind in the Eyes Test (a widely used measure of empathizing) and self-measured 2D:4D in a nonclinical sample is reported. No evidence for a link between empathizing and 2D:4D in either females or males emerged. Further, three meta-analyses are presented that look into the relationships of 2D:4D with autism spectrum disorder (ASD), systemizing, and empathizing. 2D:4D was substantially lower (more masculine) in ASD-affected individuals than in normal controls (d = −0.58, P < 0.001). However, 2D:4D was found to be virtually unrelated to systemizing and empathizing in normal adults. The results support the idea that high PT is a risk factor for autism, but they challenge the view that PT substantially contributes to sex differences in systemizing and empathizing. Possibly, this pattern reflects an interaction effect, whereby PT drives ASD characteristic changes only in brains with a specific damage.

Visuo-Spatial Performance in Autism: A Meta-analysis / Anne MUTH in Journal of Autism and Developmental Disorders, 44-12 (December 2014)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-12 (December 2014) . - p.3245-3263 Titre : Visuo-Spatial Performance in Autism: A Meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Anne MUTH, Auteur ; Johannes HONEKOPP, Auteur ; Christine M. FALTER, Auteur Article en page(s) : p.3245-3263 Langues : Anglais (eng) Mots-clés : Autism  Visuo-spatial  Figure Disembedding  Mental Rotation  Block Design  Navon Figures Index. décimale : PER Périodiques Résumé : Visuo-spatial skills are believed to be enhanced in autism spectrum disorders (ASDs). This meta-analysis tests the current state of evidence for Figure Disembedding, Block Design, Mental Rotation and Navon tasks in ASD and neurotypicals. Block Design (d = 0.32) and Figure Disembedding (d = 0.26) showed superior performance for ASD with large heterogeneity that is unaccounted for. No clear differences were found for Mental Rotation. ASD samples showed a stronger local processing preference for Navon tasks (d = 0.35); less clear evidence for performance differences of a similar magnitude emerged. We discuss the meta-analysis results together with other findings relating to visuo-spatial processing and three cognitive theories of ASD: Weak Central Coherence, Enhanced Perceptual Functioning and Extreme Male Brain theory.
