People with autism exhibit extreme examples of the the typical male mind, where logic and rules are stronger than empathy, according to new research.

Professor Simon Baron-Cohen, who led the study at the ARC, said: “Our study provides strong evidence in support of the ‘extreme male brain’ theory of autism.”
