Time blindness: when time cannot be felt
5 min read
Being twenty minutes late without noticing, or spending three hours on a task that felt like forty minutes: time blindness is a difficulty perceiving duration, common in ADHD and frequent in autism.
It is a perception difficulty, not a lack of will
Estimating how long something takes, feeling time pass and noticing that a deadline is approaching all rely on executive functions. When those work differently, the internal clock gives no signal — and no amount of good intentions supplies one.
Make time visible
A visual timer that shrinks as time passes, an analogue clock with the end of the activity marked, or a simple announcement of the duration before starting: the point is to move time from something felt to something seen.
Anchor tasks to events, not to hours
"After breakfast" is easier to catch than "at 8:15". Chaining a task to an event that already happens every day removes the need to monitor the clock at all.
