ngd- I wouldn’t make more out of this than it is, but there are some useful insights in this theory...
“Up until now there have been a lot of theories about the possible causes of autism but none of those theories account for the majority of autism cases,” McDonald said. “There are also a lot of theories as to why the prevalence of autism has been increasing in the population but, to date, there hasn’t been a theory that provides an explanatory model that accounts for all of those phenomena, including the genetics, social history, or characteristics of autism.”
The CDC estimates that 1-in-54 persons are on the autism spectrum.
McDonald’s theory, titled ‘The Broader Autism Phenotype Constellation-Disability Matrix Paradigm (BAPCO-DMAP) Theory,’ is consistent with the current science on the genetics of autism but shifts the focus to positive traits of autism and to historical events that changed the prevalence of autism in society.
“The BAPCO-DMAP theory describes how people are attracted to other people who are very similar. They are attracted to certain traits that are very common in the population, and this leads to offspring who are more likely to have certain traits, as well as a greater intensity of traits.” McDonald said.
“The (BAPCO) traits are not what people expect. They expect the traits to be about challenges or difficulties, but instead there are six main traits — increased attention, increased memory, a preference for the object world vs. the social world and their environment, increased nonconformity, increased differences in sensory and perception, as well as systemizing.”
