The idea of time blindness, or difficulty perceiving and managing time, has spread across social media. While there is no diagnosis for it, some people explain that, despite their best efforts, they frequently lose track of time, underestimate or overestimate how long tasks will take, show up late, and miss deadlines.
Time blindness is a psychological phenomenon that nearly everyone experiences from time to time, said Michael Manos, at the Cleveland Clinic.
“Who doesn’t get completely occupied with a hobby or a conversation they’re having with somebody, or some kind of activity that is so interesting that it occupies attention, and it takes attention away from other things that might be pressing?” he said.
Not all experts agree, but some suggest that it could be a limitation for some people.
Renae Beaumont, an associate professor of psychology in clinical psychiatry, said time blindness and flow, a state of intense focus in an activity that is engaging, enjoyable and temporarily distracts from the passage of time, are different phenomena.
“Flow is typically associated with positive emotions when you’re doing something you enjoy, and you are able to shift to a different task when you need to. Time blindness involves getting stuck, losing track of time and typically having trouble transitioning to a different task,” she said.
There is no clear consensus, but some researchers consider time blindness to be an impairment in temporal perception, or the way the brain experiences time.
Certain strategies may help people who struggle with time perception and management, experts said. Use digital reminders including alarms, timers and calendars to keep track of appointments, dates and deadlines. Washington Post.
