Which of the following is a sensory replacement behavior?

A sensory replacement behavior is typically a substitute for sensory experiences that may be overwhelming or non-regulated. Fidgets serve this purpose by providing a tactile and sensory outlet that can help individuals manage sensory input in a more controlled and beneficial way. They allow individuals to engage their sense of touch without causing disruption to themselves or others, thereby aiding in self-regulation and focus.

In contrast, yelling is often an expression of frustration or an uncontrolled emotional response that does not serve as a substitute or replacement for sensory input. Sitting still does not represent a sensory replacement; rather, it suggests a lack of movement that may not address the sensory needs of an individual who requires sensory input to thrive. Similarly, taking long breaks, while helpful in some contexts, generally does not provide immediate sensory engagement or fulfillment, which is critical for someone seeking to replace sensory experiences.
