Professor Simon Baron Cohen's research includes the theory of the extreme male brain: "Research on relatives of people with Asperger syndrome and autism has
found that their fathers and grandfathers are twice as likely to be
engineers as the general population. Natural science students have more
relatives with autism than humanities students. Asperger syndrome is
found more often in mathematicians and their siblings than in the
general population. Both mothers and fathers of children with Asperger
syndrome tend to score high on systemizing. Both mothers and fathers of
children with autism or Asperger syndrome often have father who worked
in systemizing occupations. Both mothers and fathers of children with
autism have a strongly masculine pattern of brain activity when doing
systemizing activity.*" The study below found otherwise.

In two experiments, we tested some of the central claims of the empathizing-systemizing (E-S) theory.
Experiment 1 showed that the systemizing quotient (SQ) was unrelated to performance on a mathematics test, although it was correlated with statistics-related attitudes, self-efficacy, and anxiety. In Experiment 2, systemizing skills, and gender differences in these skills, were more strongly related to spatial thinking styles than to SQ. In fact, when we partialled the effect of spatial thinking styles, SQ was no longer related to systemizing skills.
Additionally, there was no relationship between the Autism Spectrum Quotient (AQ) and the SQ, or skills and interest in mathematics and mechanical reasoning.
We discuss the implications of our findings for the E-S theory, and for understanding the autistic cognitive profile.
