Humphreys quoting Grandin
The quote by Grandin in “What is orientation?” and “More about Central coherence” and other places was found in this article by Simon Humphreys: ‘Architecture: Taking autism into account or not?’ (2008). He doesn’t give a reference for this quote.
Humphreys’ article doesn’t give a publisher and is very hard to find on the Internet since the website of the Belgian ‘Universal Design – Design for Autism’ was cancelled.
Humphreys well illustrated article is part of what we consider ‘the core literature’.
