Your attention span is the length of time you can stay on one task before your mind or your hand moves somewhere else. You can increase it, and the methods that work are less about willpower than about changing what competes for your attention: where your phone sits, how you schedule breaks, how much you sleep, and whether you train focus on purpose.
If you have noticed that you read three paragraphs and reach for your phone, you are not imagining it. The research below explains why it happens, and the seven steps that follow turn that research into a routine you can start today.
What Attention Span Really Means
Psychologists do not treat attention as one thing. Sustained attention is the ability to stay on a single task over time, selective attention is the ability to ignore what does not matter, and both draw on the same limited pool of mental resources. When people talk about a short attention span, they usually mean sustained attention breaking down early.
The best real world data comes from Gloria Mark, a chancellor's professor of informatics at the University of California, Irvine, who has measured how people actually use screens for more than twenty years. In a SciLine interview, she described how the average time spent focused on one screen dropped from two and a half minutes, to 75 seconds, to just 47 seconds today.
The decline is real, but it describes how we use screens, not a fixed limit of the human brain. That distinction matters, because it means the number moves when the environment changes.
The Goldfish Attention Span Myth
You have probably heard that the average human attention span is eight seconds, one second shorter than a goldfish. The claim went viral after a 2015 Microsoft Canada advertising report, which credited the figures to a website called Statistic Brain rather than to a study.
When the BBC investigated the statistic, it found no evidence that goldfish, or fish in general, have particularly short attention spans or memories. Researchers have published hundreds of papers on goldfish learning and memory, going back as far as 1908.
So drop the goldfish comparison. The useful question is not how your attention compares to a fish, but what pulls it away and how to pull it back. That is what the steps below address.
What You'll Need
None of these steps require special equipment. You will get more out of them with a few simple things in place:
- A timer, either on a watch or a kitchen timer, so your phone does not have to be the clock
- A place to put your phone that is out of sight, such as a drawer, a bag, or another room
- A notebook or notes app for jotting down stray thoughts so they stop circling
- Ten minutes a day for the first two weeks to practise and track progress
Step 1: Take an Attention Span Test on Yourself
Before you change anything, measure where you are. Pick a task that needs real focus, such as reading a chapter or writing a report, start a timer, and note the moment you switch away for any reason: a phone check, a new tab, a snack. Do this three times across a normal day.
You are not looking for a score to compare with anyone else. Online attention span tests exist, but your own baseline on your own work is more useful, because it shows what actually interrupts you. Write down what triggered each switch.
After a few days, a pattern usually shows up. For some people it is notifications, for others it is the urge to look something up, and for many it is simply hitting a hard sentence and wanting relief. Each pattern points to a different step below.
Step 2: Move Your Phone Out of Sight
This is the step with the most direct evidence. A study by Cary Stothart and colleagues in the Journal of Experimental Psychology found that phone notifications alone significantly disrupted performance on an attention-demanding task, even when participants never touched their phones. The size of the distraction was comparable to actively making a call or sending a text.
A 2017 study by Adrian Ward and colleagues went further and suggested that the mere presence of your own smartphone on the desk reduces available cognitive capacity, with the largest cost for people most dependent on their phones. Later work has been less clear: a pre-registered replication found no difference between phone locations, so treat the "mere presence" effect as possible rather than proven.
The notification effect is the solid one, so silence notifications and put the phone where you cannot see it. Gloria Mark gives the same advice: phone out of sight, less clutter around you, and a quiet space to work.
Step 3: Work in Focus Blocks With Real Breaks
A common mistake is to treat focus as something you should hold all day and feel guilty about losing. Gloria Mark calls this a myth. On her website she compares sustained focus to lifting weights: you cannot do it nonstop, and you need rest between sets to replenish your resources.
In practice, that means working in blocks. Start with whatever your Step 1 baseline suggests you can manage, perhaps 15 or 20 minutes, then take a short break that genuinely rests you. A walk outside counts. Scrolling a feed does not, because it is just more screen switching.
Keep one task per block. Jumping between tasks feels productive, but each switch carries a cost, which is why task switching drains focus faster than the work itself. Extend the block by five minutes once the current length feels easy.
Step 4: Protect Your Sleep
If you want to know which mental ability suffers most when you are tired, the answer is attention. Julian Lim and David Dinges analysed 70 articles covering 147 cognitive tests in a sleep deprivation meta-analysis published in Psychological Bulletin.
The effects ranged from small and nonsignificant for reasoning accuracy to large for lapses in simple attention. Of all six cognitive areas they studied, simple attention and vigilance took the biggest hit from lost sleep. The authors describe vigilance as the fundamental process that sleep deprivation affects, and the one people can least compensate for.
That means no focus technique will fully make up for a short night. If your attention span test showed far more switches on some days than others, compare those days against how you slept before them.
Step 5: Move Before Demanding Work
Exercise helps attention, though less dramatically than fitness marketing suggests. A 2012 meta-analysis by Yu-Kai Chang and colleagues in Brain Research pooled 79 studies and found that a single bout of exercise has a small positive effect on cognitive performance afterwards.
For children the picture is stronger. A 2018 meta-analysis by de Greeff and colleagues found that acute physical activity had a positive effect on attention in preadolescent children, with an effect size of 0.43 across six studies.
The practical version is simple: a brisk walk or a few minutes of movement before a long study session or meeting costs little and may help. It also doubles as the kind of real break Step 3 recommends.
Step 6: Try Meditation for Attention Span
Mindfulness meditation is, at its core, attention training. You hold attention on one thing, usually your breath, notice when it drifts, and bring it back. Each return is a repetition of exactly the skill a short attention span lacks.
The evidence is encouraging but measured. A 2021 meta-analysis of 87 studies by David Sumantry and Kathleen Stewart in the journal Mindfulness concluded that meditation may improve some, but not all, attentional processes. It is a training tool, not a cure.
Start with five minutes a day of focused breathing. When your mind wanders, label it "thinking" and return to the breath without judging yourself. The wandering is not failure; noticing it is the exercise.
Step 7: Give Your Attention Something to Do
Passive input is the hardest thing to stay focused on. A long lecture, a dense reading, or a meeting where you just listen gives your mind plenty of room to drift. Active work holds attention better, because you have to produce something.
Turn listening into doing. Write questions in the margins, summarize each section in one sentence before moving on, or explain the idea out loud as if teaching it. With Primo Notes, you can record a lecture or meeting, get a structured note and transcript, and then generate a quiz from that note, so your review session is active retrieval rather than rereading.
Recording also removes a quiet source of anxiety. When you know the full content is captured, a lapse of attention in the middle of a lecture is not a disaster, and you can stay with the speaker instead of racing to write down every word.
Tips for Better Results
A few habits make the seven steps stick:
- Change one thing at a time for a week, so you can see which step made the difference
- Keep a "later" list beside you and write down every stray thought instead of acting on it
- Schedule your hardest work for the time of day your baseline showed the fewest switches
- Repeat your Step 1 test every two weeks to track whether your focus blocks are getting longer
For a deeper look at building long stretches of concentration into your week, the guide to deep work covers how to plan and protect them.
Troubleshooting Common Issues
I keep reaching for my phone even when it is in another room
That reach is a habit loop, and it fades with repetition. Note each urge on your later list, and expect the first week to feel uncomfortable. If your phone is also your study tool, put the material you need on paper or on a different device for the session.
My short attention span gets worse in the afternoon
Look at sleep first, then at breaks. An afternoon slump after a short night is the vigilance effect Lim and Dinges describe. If sleep is fine, shorten your focus blocks in the afternoon and add a walk between them.
I cannot focus during long lectures or meetings
Sitting still and listening for an hour is hard for almost everyone. Use Step 7: give yourself a job, such as writing one question per topic. Primo Notes can record the session with speaker labels, which lets you engage with the discussion and review the details afterwards.
Meditation makes me more restless
Shorten the session to two or three minutes, or try a walking meditation where you focus on each step. The aim is repetitions of returning your attention, not long sits.
Conclusion
Attention span on screens has fallen to an average of 47 seconds, but the goldfish comparison is a myth and the number is not fixed. It responds to your environment and habits.
The strongest levers are the ones with the clearest evidence: silence notifications and keep your phone out of sight, protect your sleep, and work in focused blocks with genuine rest between them. Exercise and meditation add smaller but real gains, and turning passive listening into active work gives your attention something to hold onto. Measure your baseline, change one thing at a time, and the minutes add up.
