How to Improve Processing Speed for Better Performance
Processing speed measures the rate at which the brain receives, interprets, and responds to information. For children and adults alike, slow processing can make everyday tasks feel frustratingly difficult, even when intelligence and motivation are high.
Therefore, how to improve processing speed? Is it possible? The short answer is yes, processing speed can be supported, strengthened, and improved. This article explores what processing speed really is, how it is used across different ages, what causes slow processing speed, and what you can do about it.
Key Takeaways
-
Slow processing speed is not the same as low intelligence. Many bright individuals simply need more time to interpret and act on information, but that doesn’t reflect their ability to think deeply or solve complex problems. However, slow processing speed can affect learning.
-
Processing speed can improve with the right mix of strategies: from executive function training and lifestyle changes to assistive technology and targeted brain training like neurofeedback.
-
Adults and children benefit from different approaches, but both can make lasting gains through consistent, well-matched interventions, including physical movement, better time awareness, and mental agility exercises.
What Is Processing Speed?
Processing speed refers to the pace at which an individual takes in information, makes sense of it, and begins to respond. It is the cognitive bandwidth needed to interpret and act upon stimuli. For instance, when reading a sentence, your brain quickly deciphers the words, their meanings, and the context to understand the message.
This ability to process information efficiently is crucial in daily life, especially in learning environments where students need to grasp new concepts quickly and process information. Therefore, processing speed may impact their ability to follow instructions accurately.
A common misconception is that slower processing speed indicates lower intelligence. However, this is far from the truth. Many individuals with high IQs may process information more slowly, but this does not reflect their overall intelligence. Processing speed measures the speed and accuracy of responses, not the depth of understanding or one's ability to solve complex problems.
How Slow Processing Speed Presents in Daily Life
Children and adults with slow processing speed often appear "slow" in daily activities. For example:
-
A child may take 10 minutes just to start getting dressed, even when fully awake and motivated.
-
A student may leave class assignments unfinished, not due to lack of knowledge, but because the work simply takes longer.
-
A teenager may spend hours on homework that others complete in 30 minutes.
In such cases, parents and teachers may work together to determine how much extra time the child needs to finish a task, take notes, or get from point A to point B while reading a text, for example.
In adults, the symptoms may manifest differently but no less impactfully:
-
Needing longer than peers to complete routine work tasks
-
Avoiding deadlines because of perfectionism or anxiety
-
Having a difficult time to respond quickly in fast-paced meetings or group discussions
-
Feeling overwhelmed by multitasking or time-sensitive demands
Why Do Some People Process Information More Slowly?
Before discussing more details about methods that can help you improve processing speed, it's important to highlight the most common reasons that cause some people to process information more slowly. The solution differs depending on the cause.
1. Neurodevelopmental Conditions (e.g., ADHD)
One of the most common associations with slow processing speed is attention-deficit hyperactivity disorder (ADHD), especially the inattentive subtype. These people may have a sluggish cognitive tempo. They may seem “spacey,” daydream often, and have difficulty initiating or sustaining attention.
Dr. Thomas Brown’s model of executive functioning highlights that persons with ADHD may experience impairments in areas like task initiation, focus, effort, and working memory. All of these can contribute to slow processing. A child with executive dysfunction might struggle not because they don't understand the material, but because getting started, staying focused, or recalling steps takes them longer than peers.
2. Learning Disabilities and Sensory or Motor Challenger
Processing speed is also influenced by other learning disorders, including dyslexia and dysgraphia. Children with these challenges often have significant gaps between their verbal reasoning and their processing speed scores.
In tasks requiring rapid writing or manipulation, children with dysgraphia or fine motor deficits may perform poorly—not because they don’t know the answer, but because writing or physical output slows them down.
3. Physical and Emotional Factors
Other contributors to slow processing include:
-
Medical issues: low thyroid function, epilepsy, traumatic brain injury, or reaction to medications.
-
Lack of sleep: fatigue greatly impairs processing efficiency.
-
Emotional challenges: anxiety, perfectionism, and OCD may prevent people from completing tasks on time. For example, a child with OCD may feel compelled to redo work to make it “perfect,” significantly slowing academic performance.
How to Improve Processing Speed in Children?

An important question arises: can you enhance processing speed? The simple answer is yes, though the extent of improvement depends on the cause. Some people can build greater efficiency through cognitive training and targeted practice, while others benefit more from workarounds and environmental adjustments. For many, a combination of both leads to the best results.
As such, how exactly can you improve processing speed? In the following sections, we'll discuss some methods that could work well for children.
1. Build Executive Functioning Skills
Children who process information more slowly often have trouble with executive functions—the brain's "management system" that helps with planning, organizing, starting tasks, shifting focus, and self-monitoring. Strengthening these skills lays the groundwork for more efficient thinking and processing.
When executive functioning improves, children can better prioritize information, ignore distractions, and stay mentally organized.
Activities that help:
-
Sorting tasks (by color, shape, size)
-
Timed puzzles and board games (like Spot It!, Blink, or Boggle)
-
Planning activities (like cooking with a recipe or organizing a backpack)
2. Practice Timed Tasks in a Low-Stress Way
Timed activities can help children build mental endurance and speed, but if done in a pressurized way, they may increase anxiety and avoidance. The goal is to introduce speed gradually and playfully.
Here's what you can try:
-
Reading short paragraphs aloud under time to improve reading fluency
-
Copying simple sentences
-
Playing “beat the clock” with math facts or matching games
Make sure that time limits are generous enough to be achievable, then gradually adjust.
3. Use Technology and Assistive Tools
Children with slow processing speed may need alternative ways to express what they know. Assistive technology can reduce the bottleneck created by slow motor output, reading, or writing, and allow cognitive energy to be used more effectively. In other words, when kids can skip the struggle of handwriting or reading at a slow pace, their ideas and understanding can shine!
-
Speech-to-text tools
-
Typing instead of writing
-
Audiobooks or text-to-speech readers
-
Timers and task apps like Time Timer or Visual Schedule Planner
4. Use Graphic Organizers and Templates

Graphic organizers help children organize thoughts visually, reducing cognitive overload and increasing clarity when planning, writing, solving problems, or studying.
Try:
-
Sentence starters
-
Venn diagrams
-
Step-by-step math templates
5. Break Tasks into Smaller Steps
When given large or open-ended tasks, children with slow processing speed may freeze or procrastinate. Because of this, chunking can be incredibly useful, as it provides them with clear, manageable steps.
Here are some methods you can try:
-
Use checklists with visuals. Break homework assignments into mini-steps. Example:
-
[ ] Read the directions
-
[ ] Highlight keywords
-
[ ] Solve problem 1
-
[ ] Show your work
-
[ ] Double-check
-
Create “first...next...last” routines. This method is especially helpful for multi-step instructions in math problems, writing, or chores.
-
Limit choices: instead of asking, How do you want to start your story?, try: Do you want to begin with a setting or a character?
-
Use color-coded steps: assign different colors to different task types or stages of work (e.g., red = read, blue = write, green = check).
6. Incorporate Physical Movement
Movement and exercise increase blood flow to the brain, improve attention, and stimulate the release of neurochemicals like dopamine and serotonin.
Research consistently shows that aerobic exercise can improve processing speed and executive function in both children and adults. One study found that cardiovascular activity led to a significant 12.5% improvement in processing speed!
Here are some activities you can try with your kids:
-
Jump rope
-
Tag games
-
Dancing to music
-
Yoga or martial arts
How to Improve Processing Speed in Adults?
While slow processing speed is usually linked to the same factors in both adults and children, there are methods that are more useful for adults than children. Therefore, in the following sections, we'll discuss some techniques that can help adults enhance processing speed.
1. Train the Brain with Neurofeedback

The human brain has a unique ability, neuroplasticity, that allows it to change and adapt. This means that cognitive abilities like processing speed, working memory, and attention control can be improved with regular, targeted mental exercise.
You can try neurofeedback, for example, which leverages neuroplasticity to improve cognitive performance. If your goal is to enhance processing speed with neurofeedback, your best bet is the Mendi headband. Why? Because it is the only consumer-grade device on the market that targets the prefrontal cortex, the brain region responsible for focus, information processing, planning, problem-solving, decision-making, and working memory.
Plus, we've designed our system to work in an interactive way (suitable for children aged 6+ as well): while wearing the headband, you have to play a game on our app, which is basically controlled by your prefrontal cortex activity. When it increases, the ball on the screen goes up. When it decreases, the ball goes down.
Over time and with consistent practice, you can strengthen your prefrontal cortex and experience an improvement in processing speed and other cognitive skills.
However, keep in mind that Mendi is not a medical device and should not substitute medical advice, diagnosis, and treatment. It is recommended to talk to your doctor before using Mendi if you have a medical condition.
2. Practice Mental Agility Exercises
Processing speed is not only about how quickly the brain can absorb and react to information—it also hinges on mental flexibility, pattern recognition, and working memory. Engaging regularly in activities that challenge these abilities encourages the brain to work more fluidly under pressure.
Try these mental agility activities:
-
Crossword puzzles to improve word retrieval and language speed
-
Sudoku and number puzzles to strengthen logic under time constraints
-
Memory matching games (digital or physical) to improve memory
-
Timed chess or strategy card games (like Speed or Set)
-
Speed-reading short stories or articles, then summarizing quickly to improve reading speed and comprehension
-
Listening to audiobooks or podcasts at 1.25x–1.5x speed
3. Improve Sleep, Nutrition, and Exercise
The brain relies on high-quality sleep to clear waste, solidify memories, and enhance executive function. On the other hand, nutrition provides the fuel for mental tasks. Last but not least, physical activity increases blood flow to the brain and triggers the release of beneficial neurotransmitters.
When any of these three pillars—sleep, food, or movement—is out of balance, processing speed can suffer the consequences.
As such, here are some healthy habits you can adopt:
-
Get 7–9 hours of sleep per night (children and teens may need more).
-
Follow a consistent sleep routine with limited screen time before bed.
-
Eat omega-3-rich foods (salmon, walnuts, flaxseeds) for brain health.
-
Include leafy greens and berries, which support memory and cognition.
-
Stay hydrated—even mild dehydration can impair mental speed.
-
Exercise regularly, especially aerobic activity (walking, cycling, dancing).
-
Try coordination-heavy sports like tennis or martial arts to build brain-body synchrony.
-
Use movement breaks (5–10 minutes) during long mental tasks.
5. Learn Typing and Keyboard Shortcuts

Nowadays, much of our productivity depends on how efficiently we interact with technology. For individuals who struggle with processing speed, especially adults, written output can be a major bottleneck. However, this can often be improved with better digital fluency.
Here's what you can try:
-
Practice touch typing with free programs like TypingClub or Keybr.
-
Aim for 40+ WPM (words per minute) for average workplace efficiency.
-
Learn commonly used keyboard shortcuts (copy/paste, navigation, formatting).
-
Use browser extensions that automate repetitive text or actions.
-
Try speech-to-text tools like Google Docs voice typing.
-
Use Grammarly or editing tools to reduce time spent proofreading.
6. Delegate or Outsource Repetitive Tasks
Mental energy is finite. When processing information consumes a disproportionate share of that energy, it can lead to burnout, especially when tasks are repetitive or low-value. But if you delegate or automate these duties, you free up bandwidth for higher-order thinking and creativity.
Try these methods to lighten the mental load:
-
Delegate household chores using chore charts, family planning apps, or hired help.
-
Outsource admin work via virtual assistants or team members.
-
Use automation tools like Zapier or IFTTT to handle routine digital tasks.
-
Try scheduling tools (Calendly, Doodle) to avoid emailing back and forth.
-
Batch similar tasks together to reduce mental switching costs.
-
Use smart home devices (e.g., reminders, timers, lists via Alexa or Google Home).
7. Use Timers to Build Time Awareness
A common challenge for people struggling with processing speed is a distorted sense of how much time a task takes—either underestimating (leading to lateness) or overestimating (leading to overwhelming feelings). Because of this, it's important to build accurate time estimation and time-tracking habits.
Try these strategies to build time awareness:
-
Use the Pomodoro technique (25 minutes focus + 5-minute break).
-
Try a Time Timer, which shows time shrinking visually.
-
Conduct a time audit to track how long daily tasks actually take.
-
Use app-based timers with analytics (e.g., Forest, Toggl, Focus Keeper).
-
Create mini-deadlines within larger projects to keep momentum.
8. Manage Anxiety and Perfectionism
Anxiety and perfectionism are often the main causes of slow processing in adults. When the brain is preoccupied with What if I fail?, it can’t focus on the task at hand. This internal pressure creates a feedback loop: slower performance causes more anxiety, which further slows you down.
Here are some helpful practices you can try:
-
Use affirmations or self-talk (e.g., It’s okay to make mistakes, there's no need to go through this email three times.)
-
Journal briefly before tasks to offload intrusive thoughts.
-
Practice mindfulness or breathing exercises.
-
Break large tasks into tiny, low-pressure actions.
-
Work with a therapist or coach to address core beliefs about failure or self-esteem.
-
Normalize effort over perfection by reflecting on what went well, not just what was fast.
When to Seek Professional Support
If processing speed issues significantly impair functioning, it may be time for:
-
A neuropsychological evaluation (children or adults)
-
Assessment for ADHD, learning disorders, or emotional issues
-
Cognitive tests, such as the Wechsler Intelligence Scale, to measure processing speed
-
Consultation with an occupational therapist (especially for motor-related speed issues)
-
Support from an executive function coach or educational therapist
For some individuals with ADHD, medications may indirectly improve processing speed by enhancing focus and activation. Always consult a healthcare provider for medication options.
