Individuals with Autism Spectrum Disorder (ASD) often exhibit behaviors or interests that may appear unusual. These distinctive behaviors help to differentiate ASD from conditions that primarily involve difficulties with social communication and interaction.

· Examples of restricted or repetitive behaviors and interests associated with ASD include:
·
· - Lining up toys or other objects and becoming upset if the arrangement is changed.
· - Repeating words or phrases multiple times (a phenomenon known as echolalia).
· - Playing with toys in the same manner each time.
· - Focusing intently on specific parts of objects (for instance, wheels).
· - Becoming distressed by minor changes in their environment.
· - Having obsessive interests in particular topics or activities.
· - Adhering to specific routines that must be followed.
· - Engaging in repetitive physical movements, such as flapping hands, rocking the body, or spinning in circles.
· - Displaying unusual reactions to sensory experiences, such as how things sound, smell, taste, look, or feel.
