What is an example of hyper or hyporeactivity to sensory input?

The example of excessive touching or smelling of objects effectively illustrates hyperreactivity to sensory input. Hyperreactivity occurs when an individual is overly responsive to sensory stimuli, such as tactile or olfactory sensations. In this case, excessive touching or smelling can indicate that an individual has a heightened sensitivity to these senses, engaging with objects in a way that may seem excessive or unusual to others.

Comparatively, being cautious around new social settings reflects an adaptive behavior rather than a direct response to sensory input. Having a strong attachment to other people can indicate emotional connections but does not relate to sensory processing. Ignoring changes in routine is more associated with rigidity or a need for predictability, which does not specifically correspond to either hyper or hyporeactivity to sensory stimuli. Therefore, excessive sensory interactions are the most relevant example of this phenomenon.
