Rigid thinking patterns are closely associated with which behavior feature?

Rigid thinking patterns are closely associated with insistence on sameness. This behavior reflects a strong preference for routine and consistency, as individuals with rigid thinking often find comfort in familiar patterns and may become distressed when faced with changes in their environment or daily routines. Insistence on sameness can manifest in various ways, such as sticking to the same schedule, becoming anxious about changes, or having a strong resistance to new experiences. This characteristic is particularly prevalent in individuals with autism spectrum disorder, where maintaining predictable environments can help reduce anxiety and promote comfort.

The other options, while related to behavioral features, do not directly align with rigid thinking patterns in the same way. Stereotyped or repetitive behavior refers to repetitive actions or phrases rather than thought processes. Highly restricted interests focus on intense focus in particular areas rather than inflexibility in thinking or routines. Hyper or hyporeactivity pertains to sensory responses, which is also a different behavioral domain. Thus, insistence on sameness is the most fitting answer as it directly embodies the concept of rigid thinking.
