Which behavior is most commonly observed in a child with autism spectrum disorder?

Children with autism spectrum disorder (ASD) often exhibit unique preferences and behaviors that can set them apart from neurotypical children. One of the commonly observed behaviors in children with ASD is a heightened interest in specific areas, including music. This interest can manifest as an intense focus on certain songs, instruments, or rhythms, demonstrating a deep connection or affinity for musical elements.

Unlike the other behaviors listed, which typically involve social interactions and attachments that may be more challenging for children with ASD, an interest in music can provide a form of expression and engagement. Many children with autism find comfort and joy in music, which may serve as a therapeutic avenue that reflects their different ways of processing sensory information.

The other behaviors mentioned, such as outgoing behavior, attachment to friends, and high responsiveness to parents, are often less characteristic of children with autism. These social behaviors tend to be challenging for them, as they may struggle with initiating or maintaining interactions, forming friendships, or responding to parental cues in typical ways. Therefore, interest in music stands out as a more representative behavior commonly observed in children with autism spectrum disorder.
