Stimming is the family of repetitive movements, sounds, and sensory habits people use to regulate themselves; the word comes from the autism community, but the impulse is near-universal — we just call the quiet versions "fidgetingintrinsic fidgetingSmall, spontaneous repetitive movements — such as a swinging foot or a twirling pen — that a person generates on their own during a task.Glossary →." Acceptance is not noticing it, which is involuntary, nor merely tolerating it, which still carries the freight of permission. It is the absence of judgment: the stance that a self-regulating body needs no fix, comment, or managing. It is distinct from ignoring distress — a partner rocking through a crisis may still need comfort — and from endorsing genuinely self-injurious stimmingself-injurious stimmingRepetitive self-stimulating movement that physically harms the person doing it, such as head-banging or skin-picking that breaks the skin — distinct from…Glossary →, which is a real exception that calls for care.
The most direct evidence is autistic self-report. Kapp and colleagues found stimming functions as emotional self-regulation, is socially stigmatized, and is suppressed almost entirely for external reasons — fear of judgment, not dislike of the stimming itself 1; a 2025 replication across two samples reached the same conclusion 2, and the APA describes stimming as serving real calming purposes even when it looks purposeless 3.

Separately, ADHD research finds "intrinsic fidgeting" can aid attention rather than undermine it 67, undercutting the old assumption that visible movement should be stopped.
Why it matters
Why it matters. A partner is meant to be the one place the performance can stop. Acceptance removes a layer of self-vigilance, and it preserves stimming as an honest, readable signal of a person's inner weather.
How to cultivate it
How to cultivate it. Interrogate your own flinch — most stilling serves the stiller — practice the non-response, ask once what your partner wants and honor it, carry the acceptance into public, and treat genuinely self-injurious stimming as a separate matter of care.
The honest caveat
The honest caveat. The strongest evidence is qualitative self-report, and the masking-and-mental-health link is correlational and genuinely debated 5; the ADHD-fidgeting findings concern attention, not couples 67. That your acceptance helps your partner is a well-grounded inference plus a clear, direct request from the people who stim 1.
