A book to understand the Autism Spectrum Disorder.For parents and friends of people affected by it, a book to finally understand why they behave the way they do.For neurologists, a novel theory on the cause of the disorder, and for psychologists, a novel theory on the causes for the learning disabilities (and how they can be mitigated).For people on the Spectrum, a book to understand themselves and the weird world of Neurotypicals.Some of the topics covered inside:* The Magnifying Glass: a metaphor to understand perception under the Spectrum* Why people on the Spectrum are impaired in contextual fields (such as personal communication) and advantaged in mastering detailed fields (such as computer science).* Peripheral Functionality Blindness: the reason people on the Spectrum do not develop appropriate body language and facial expressivity.* Prioritization by Specificity: the reason literal meaning is the only thing which matters, for people on the Spectrum.* The High-Pass filter: a novel hypothesis for the Autism Spectrum Disorder, coherent with previous theories and experimental results.(Reading time is about 1h30)
