The following is an interview I had with my son Kyle, where I asked him questions about school and a book that he read recently. I wanted to demonstrate the difficulty that autistic children have with abstract thinking. Kyle is thirteen years old, and has autistic disorder.
Abstract vs. Concrete 
Remember that abstract thinking involves predicting, forming an opinion, understanding emotions and motivations, etc. What is interesting to note is that when I ask Kyle a concrete question where I’m looking for a specific fact, he is able to answer it quickly and correctly. But when I ask an abstract question, he struggles to come up with an answer. When he does answer, he often poses the response as a question to me, as though he’s not sure whether the answer is “right.” Sometimes there is no “right” answer, for example, when I ask him his favorite subject in school. But for Kyle, everything is either right or wrong.
With concrete subjects, such as mathematics and geography, Kyle is a super-wiz. But simple abstract questions often confound him. I have typed his answers, verbatim, and have put the abstract questions in italics.

Well, that’s a perfect way to end. Thank you, Kyle.
