How to Improve Processing Speed in Adults and Teens
If you're wondering how to improve processing speed in adults or teens, the most reliable route is plain practice: make the basic steps of a task so familiar that they run automatically. Add enough sleep, some exercise and fewer interruptions, and most people get noticeably quicker at the things they practise. What rarely works is hoping a generic brain game will make you faster at everything.
If you feel slow on reasoning questions and aren't sure whether it's speed, memory or rushing then freezing, IQ Tester checks seven weak spots and trains the ones you have: Find my weak spots.
What processing speed is
Processing speed is how quickly you take in information, make sense of it and respond. Reading a question, spotting that two shapes match, adding a column of numbers: each has a speed component.
A few things are worth knowing up front:
- It's task-specific more than people think. Someone can be lightning fast at mental arithmetic and slow at reading dense text.
- It's not the same as intelligence. Speed helps on timed tests, but slow and accurate thinking is still good thinking.
- "Processing speed index" is a test score. On some formal cognitive tests, like the Wechsler scales, it's one subscore among several. Those tests are given by trained professionals, not online quizzes.
Processing speed vs working memory
People often ask how to improve processing speed and working memory together. They're linked but different. Working memory is how much you can hold in mind at once. Processing speed is how fast you work with it. When basics are automatic, both feel better, because fast, automatic steps use up less of the space you hold things in.
If you think you have slow processing speed that affects school, work or daily life, talk to a doctor, school psychologist or counselor. This guide is about everyday practice, not diagnosis.
Speed comes from automatic basics
Here's the core idea. Think back to learning to ride a bike or type. At first, every step needed attention. Now it doesn't. That shift, from effortful to automatic, is where most real speed comes from.
The same thing happens with thinking tasks:
- A student who knows 7 × 8 = 56 by heart solves a long multiplication faster than one who counts up.
- A reader who knows common words instantly moves through a passage faster than one who sounds them out.
- A test taker who recognizes "this is an alternating series" skips several seconds of staring.
So the practical question isn't "how do I make my brain faster?" It's "which basic steps am I still doing slowly, and how do I make them automatic?"
Find your slow steps
Pick a task you want to be faster at, then time yourself on its parts. For a math test, you might check:
- How long you take to read and understand the question
- How long simple arithmetic takes
- How long you spend checking
Usually one part is much slower than the rest. That's your target.
Practise the same item types
To build automaticity, you need repetition of the same kind of thing, with feedback. Variety is fun, but too much of it spreads your practice thin.
Good processing speed exercises share three features:
- Narrow: one item type at a time, like number series or percentage questions.
- Short: 5 to 15 minutes, done often.
- Checked: you find out right away if you were right.
| Goal | What to practise | Example |
|---|---|---|
| Faster mental math | Estimates, times tables, splitting numbers | 10 two-digit multiplications a day |
| Faster pattern spotting | One puzzle family at a time | Number series only for a week |
| Faster reading of questions | Timed short passages | Summarize each in one sentence |
| Faster logic questions | Common rule types | "If... then" chains, 10 a day |

The catch with "practise the same item types" is picking the right type. Most people guess, and guess wrong, so they drill what they're already good at. IQ Tester's 16 questions sort out which of seven weak spots, from mental arithmetic to pattern spotting and working memory, is slowing you down, then weights your daily drill toward it.

Should speed or accuracy come first?
Accuracy first. Get the item type right slowly, then gently tighten the time. If you push speed before the steps are solid, you get fast and wrong, which is worse on any test.
Sleep and exercise
These sound boring, but they're the easiest wins most people ignore.
Sleep. The US National Heart, Lung, and Blood Institute notes that sleep deficiency can make it harder to make decisions and solve problems. Teens generally need more sleep than adults, and a tired brain is a slow brain. If you're studying late the night before a test, you're trading tomorrow's speed for tonight's review.
Exercise. Regular physical activity is widely recommended for overall health, and many people find they think more clearly after moving. You don't need anything intense. A brisk walk counts.
Simple habits that help:
- Keep a steady bedtime, even on weekends, as much as you can
- Put your phone out of reach at night
- Take a short walk before a long study session
Cut task switching
Every time you switch tasks, your brain pays a small restart cost. Checking a message mid-question means you have to reload the question when you come back. Do that twenty times in an hour and you're much slower than you need to be.
To improve cognitive speed on real work:
- Batch similar tasks. Do all your math practice, then all your reading.
- Phone in another room during focused practice. Not face down on the desk. Another room.
- One tab. Close everything you don't need.
- Set a short timer. Fifteen focused minutes beats forty distracted ones.
This is especially useful when working out how to improve processing speed in students, because homework time is often full of small interruptions.
What brain-training apps can and cannot do
Search "processing speed games" and you'll find plenty of apps promising a faster brain. It's worth being honest about what the research says.
A large 2016 review by Monica Melby-Lervåg and colleagues looked at working memory training studies and found that people got better at the trained tasks, but found no convincing evidence that the gains spread to broader skills. Researchers call that "far transfer," and it's the thing many ads imply.
So:
- What they can do: make you faster and more accurate at the tasks you practise, and give you a routine.
- What they can't reliably do: make you faster at unrelated things just because you played a game.
That's why the best approach is to practise tasks that look like the thing you care about. If you want to be quicker on reasoning tests, practise reasoning-test items, especially the types you're weakest at.
Can processing speed be improved in adults?
Yes, for the tasks you practise. Adults build automaticity the same way teens do, through short, repeated, checked practice. Gains are most noticeable on familiar item types, which is why targeted practice matters more than age.
Practise the steps that are actually slow
The fastest answer to how to improve processing speed in adults and teens is to find your slow step and practise it until it's automatic. IQ Tester's 16 questions take about two minutes and show which reasoning weak spots are costing you time, then give you one tip and one roughly 10-minute drill a day aimed at them, with a history so you can see progress. You pay once and there's nothing to cancel.
FAQ
How can I increase the processing speed of my brain?
Pick specific tasks you want to be faster at, and practise the same item types daily in short, checked sessions until the steps become automatic. Sleep well and reduce task switching while you work. Generic brain games mostly improve performance on those games.
Can you improve processing speed as an adult?
You can get faster at tasks you practise regularly, at any age. The key is repetition of the same kinds of items with quick feedback. Broad claims that a single app will speed up all your thinking aren't well supported.
How do I improve processing speed for school as a teen?
Find the slowest part of your schoolwork, such as mental math or reading questions, and practise just that for 10 minutes a day. Protect your sleep, especially before tests. Keep your phone in another room during homework to cut switching.
What does Reddit say about how to improve processing speed?
Common advice on forums matches the research: practise the specific skill, sleep more, and be skeptical of apps that promise general brain boosts. The most useful threads focus on concrete routines rather than quick fixes.
Is a processing speed test online the same as a real one?
No. Online quizzes can show which tasks feel slow for you, but the processing speed index on formal cognitive tests is given by trained professionals under set conditions. If you're worried about slow processing, talk to a doctor or school psychologist.
