Which of the following characteristics was identified by Hans Asperger in his 1944 study?

The characteristic identified by Hans Asperger in his 1944 study that is most accurate is the intense focus on specific interests and clumsy movements. Asperger originally described children who had a strong, often obsessive interest in particular subjects and demonstrated a lack of coordination in their physical movements, which he referred to as "clumsiness." These traits were significant in the diagnosis and understanding of what came to be known as Asperger's syndrome, a condition on the autism spectrum. Individuals with these characteristics often display a deep knowledge in their areas of interest while struggling with social interactions and motor skills. This concept laid the foundation for the identification and support of individuals on the autism spectrum who experience similar traits.
