While most children have a favorite toy, area of interest, or object they like to collect, they also are very curious, interested, and excited about a wide variety of things. The Asperger’s Disorder child is not. He typically has one area that he is interested in, and the rest of the world holds little curiosity for him. Once the Asperger’s Disorder child develops an affinity for a particular subject or object, he becomes preoccupied, some parents would even say obsessed.
Dinosaurs, trains, and airplanes are common areas of interest. Many a child is fascinated with dinosaurs and learns their names and collects the toy figurines. The Asperger’s Disorder child, however, goes overboard and has a sole focus of gaining extensive, almost expert knowledge and vocabulary.
What separates the Asperger’s Disorder child from the other children who collect dinosaurs is his exclusive focus on dinosaurs. Every conversation becomes focused on his dinosaur knowledge, whether or not others want to hear about it. He talks literally nonstop, never pausing for a second and never giving the other person a chance to join in, change the subject, or even say he must leave.
