Which behavior is characterized by a pattern of persistent and repetitive actions?

The correct answer is characterized by a pattern of persistent and repetitive actions, which is identified as stereotypy. Stereotypy refers to repetitive movements, sounds, or expressions that are often seen in individuals with developmental disabilities, including autism spectrum disorders. This behavior can manifest as hand-flapping, rocking, or repeating phrases, and is typically consistent over time, serving either a self-soothing purpose or an expression of excitement or anxiety.

In contrast, options like autism spectrum screening and specific assessment tools, such as the Childhood Autism Rating Scale and the Social Communication Questionnaire, are designed to evaluate or identify symptoms related to autism but do not describe a specific behavior. They are focused on measurement and assessment rather than the behaviors themselves. Understanding stereotypy is crucial, as it helps educators and support staff develop appropriate interventions and support strategies for individuals exhibiting these behaviors.
