A Critical Review of the Research on the Extreme Male Brain Theory and Digit Ratio (2D:4D) / Missy L. TEATERO in Journal of Autism and Developmental Disorders, 43-11 (November 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-11 (November 2013) . - p.2664-2676 Titre : A Critical Review of the Research on the Extreme Male Brain Theory and Digit Ratio (2D:4D) Type de document : Texte imprimé et/ou numérique Auteurs : Missy L. TEATERO, Auteur ; Charles NETLEY, Auteur Article en page(s) : p.2664-2676 Langues : Anglais (eng) Mots-clés : Extreme male brain  Autism spectrum  Empathizing  Systemizing  Digit ratio  2D:4D Index. décimale : PER Périodiques Résumé : Boys are more likely than girls to be diagnosed with an autism spectrum disorder (ASD). The extreme male brain (EMB) theory of ASD suggests that fetal testosterone (FT) exposure may underlie sex differences in autistic traits. A link between the organizational effects of FT on the brain and ASD is often drawn based on research using digit ratio (2D:4D), a putative biomarker, without a full survey of the findings. This paper critically and quantitatively reviews the research on the relationship between 2D:4D and ASD as well as autism spectrum, empathizing, and systemizing measures in neurotypical populations. Overall, there is some support for the EMB theory in all four areas, particularly the 2D:4D–ASD relationship. Recommendations for future research are provided.
