Hyperfocus: what it is, and why a warning may not be enough

Hyperfocus is a state of absorption so complete that you lose track of time and stop noticing things around you. One research questionnaire describes it as not hearing your name or your phone, and putting off eating, sleeping or going to the toilet ¹. There is no agreed definition in the research literature ².

What the evidence says

People with more ADHD symptoms report hyperfocus more often, across school, hobbies and screen use ³. In a Japanese sample of 3,500 adults, hyperfocus scores correlated with both inattention and hyperactivity scores ⁴.

It is not unique to ADHD. One study found no difference between ADHD patients and a comparison group in how often or how long they hyperfocused ⁵. In a clinic sample of 170 women with depression or anxiety, hyperfocus scores rose with ADHD symptoms even in those without ADHD, and the authors concluded it is not diagnostic on its own ⁶.

It may also be less of a “superpower” than it sounds. People who are more distractible in general report more hyperfocus, which suggests it partly reflects difficulty directing attention ⁷.

Why stopping is hard. A meta-analysis of 13 adult studies found a moderate difference in switching between mental tasks in ADHD ⁸. A meta-analysis of experiments on difficult transitions describes two hypothesised reasons for them: not knowing a change is coming, and going from something rewarding to something less rewarding. Warnings and other signals target the first ⁹. In those experiments the overall differences were not statistically significant, but approaches that changed what happened after the switch were associated with larger reductions in problems than warnings and visual schedules alone ¹⁰. The studies involved people with intellectual and developmental disabilities, not adults with ADHD, so this is a lead and not a finding about hyperfocus.

What we don’t know

The authors of one review propose that hyperfocus and flow are the same phenomenon ². That has not been settled. We also found no trial testing ways for adults with ADHD to end a hyperfocus session.

Things to try

• Let a device end it. In a study of families with young children, screen time ended more smoothly when the technology, not the parent, was the one ending it ¹¹.
• Choose the sound. When 136 people doing an assembly task in noise were played a warning three times, 62% noticed it, and the type of sound mattered more than its volume ¹².
• Vary the alert. Seeing the same warning repeatedly reduces the brain’s response to it, and warnings that changed appearance were significantly more resistant to this ¹³.
• Soften the step down. A warning deals with not knowing a change is coming. If the hard part is the drop in reward ⁹, it may help to make what comes next less of a step down.
