understimulation
Too little input
Understimulation is insufficient sensory, mental, or social input—not enough happening to engage the brain.
Children may act out from understimulation; adults experience it as restlessness or boredom.
The concept appears in discussions of attention disorders, infant development, and workplace satisfaction: The job's understimulation was worse than stress would have been.
