After being considered a mental disorder for years, then a neurodevelopmental handicap, autism is increasingly being considered a human variant that sometimes involves extreme adaptive advantages and disadvantages. This point of view partly emerges from the fact that autistics perform certain human tasks at the same level, and in some cases even better than neurotypical persons. Furthermore, they perform these tasks using cognitive strategies and cerebral allocations that are different from the majority of humans. We will present some empirical and theoretical cognitive neuroscience studies from our group that support this school of thought.
