Logic, reasoning, and explanation unfortunately results in the Asperger’s Disorder child becoming angry and more insistent on his viewpoint. It is better to let him have his viewpoint. When you catch yourself feeling frustrated that he simply won’t listen to reason, you need to recognize that he is stuck in black and white thinking and end the conversation.
At a later point in time, when he is calm, you can bring up the topic and together make a list of all the possible ways to view the situation or all the possible solutions. Write down all possible ideas regardless of how good they are and do not make negative comments, otherwise your child will become resistant. Write the pros and cons of each one and then discuss which idea looks the best. Through this technique, you are teaching your child how to look at situations from another perspective. He may still rigidly hold to his original idea, but at least you are teaching him how to consider other options.
You can also encourage him to think about what someone else would do if they were in his situation. He may also be responsive to a suggestion that he ask others what they would do.
