My book was inspired by an existing psycho-linguistic assessment with the same name. “The Pyramids and Palm Trees Test” is used to evaluate the ability to access semantic representations. It uses iconic images to determine the degree to which a subject can access meaning from pictures and words. The test was developed by David Howard and Karalyn Patterson in 1992. It is among the most widely used semantic assessments, and has been adapted into many languages, and for populations around the world.
