Attention is an intentional, unapologetic discriminator. It asks what is relevant right now, and gears us up to notice only that. ~ Alexandra Horowitz

Attention [...] is the taking possession by the mind, in clear and vivid form, of one out of what seems several simultaneously possible objects or trains of thought [...] It implies withdrawal from some things in order to deal effectively with others. ~ William James

Millions of items of the outward order are present to my senses which never properly enter into my experience. Why? Because they have no interest for me. My experience is what I agree to attend to. Only those items which I notice shape my mind. ~ William James

The quotes above perfectly describe what attention is. In simpler words, attention is the brain's ability to focus on certain tasks while ignoring other things.

But what are specific types of attention responsible for? Let's find out!

1. Sustained Attention

Sustained attention refers to the ability to continuously maintain focus on one task or stimulus over an extended period of time. It is essential for activities that require prolonged concentration, such as studying, driving, or monitoring systems in professional settings.

This type of attention is critical because it underpins our capacity for productivity, safety, and learning. Without it, even simple tasks would become fragmented and inefficient.

Examples of Sustained Attention

• Reading a book for an hour without becoming distracted.

• Air traffic controllers monitoring radar systems continuously to ensure flight safety.

• Students listening to a lecture and processing information throughout its duration.

• Drivers maintaining focus during long-distance trips.

How to Improve Sustained Attention

Here are some activities you can try to improve your sustained attention:

• Practice mindfulness meditation, which trains the mind to remain present and focused.

• Use the Pomodoro Technique (short bursts of focused work with scheduled breaks) to strengthen endurance over time.

• Consider environmental factors. Your environment can greatly affect your cognitive performance, so make sure to minimize background distractions like noise and digital notifications.

• Prioritize sleep and nutrition, as fatigue and low energy significantly impair sustained attention.

2. Selective Attention

Selective attention is the capacity to focus on one particular stimulus while filtering out irrelevant information. It allows us to attend to what is most important in a given moment, even in environments filled with competing stimuli.

This skill is crucial in both everyday life and professional contexts because it helps us stay efficient, make decisions quickly, and avoid being overwhelmed.

Examples of Selective Attention

• Having a conversation in a noisy café, focusing on the speaker while ignoring background chatter.

• Musicians tuning into their own instrument during an ensemble performance.

• Students concentrating on the teacher despite distractions from classmates.

• Athletes focusing on the ball while blocking out audience noise.

How to Improve Selective Attention

Here are some activities you can try to improve selective attention:

• Engage in “spotlight exercises”, such as focusing on a single sound in a noisy environment.

• Train working memory through activities like puzzles and memory games, which enhance filtering skills.

• Use intentional focus cues, like repeating a task goal silently to reinforce attention.

• Limit multitasking, which reduces the brain’s ability to concentrate on what matters most.

3. Divided Attention

Divided attention refers to the ability to manage several tasks or stimuli at the same time.

While true multitasking is often less efficient than focusing on one activity at a time, divided attention is necessary in daily life, such as cooking while talking to someone or driving while listening to directions. It is particularly important in dynamic environments where you must adapt quickly.

Examples of Divided Attention

• Driving while talking on a hands-free phone.

• Cooking dinner while supervising children’s homework.

• Pilots managing flight instruments while communicating with control towers.

• Office workers changing presentation slides while discussing presentation details with others.

How to Improve Divided Attention

Here are some activities you can try to improve your divided attention:

• Practice dual-task exercises, such as walking while solving mental math problems.

• Build automaticity in routine tasks: this way, you'll spend less conscious effort on them.

• Use checklists or digital reminders to reduce cognitive load when juggling various tasks.

• Strengthen working memory, which supports the brain’s ability to hold and manipulate multiple streams of information.

4. Alternating Attention

Alternating attention is the ability to shift focus between two or more things that require different cognitive demands.

Unlike divided attention, which involves doing two tasks (or more!) simultaneously, alternating attention involves rapidly switching back and forth between multiple demands. This flexibility is crucial for problem-solving, adapting to changing demands, and managing complex responsibilities.

Examples of Alternating Attention

• Switching between responding to emails and answering phone calls at work.

• Chefs moving from chopping vegetables to checking the stove.

• Teachers alternating between lecturing and responding to student questions.

• Emergency responders shifting focus from assessing injuries to communicating with their team.

How to Improve Alternating Attention

Here are some activities you can try to improve alternating attention:

• Practice task-switching exercises, such as alternating between solving math problems and recalling vocabulary words.

• Use structured routines to make transitions smoother and reduce cognitive strain.

• Train cognitive flexibility through strategy games like chess or activities that demand rapid shifts in thinking.

• Take short breaks between tasks to reset mental focus and prevent cognitive fatigue.

5. Other Types of Attention

The types of attention mentioned above are generally acknowledged as the main ones. However, there are several others that are also considered types of attention, including:

• Executive attention: this attention involves the ability to regulate and control thoughts, emotions, and actions in alignment with goals. Executive attention enables decision-making, error detection, and self-control. It acts as a top-down control system to maintain goal-directed behavior.

• Focused attention: this is often regarded as the same or similar to selective attention; it is the basic ability to direct awareness toward a specific visual, auditory, or tactile stimuli. It is the foundation upon which other attention types build. For example, responding immediately when your name is called involves focused attention.

Why Is Attention So Important?

Attention plays a crucial role in every aspect of our lives, from education to workplace efficiency and beyond.

For example, sustained and selective attention are critical for academic success. Students need to maintain concentration over lengthy study periods and selectively filter distractions in noisy classrooms.

Moreover, many professions demand high levels of various attention types. For instance, surgeons require sustained and selective attention during operations, while pilots rely heavily on divided and alternating attention to manage multiple tasks simultaneously. Even office workers need to be proficient at alternating focus between emails, meetings, and projects without losing productivity.

And let's not forget the constant barrage of notifications and multitasking encouraged by smartphones and social media, which negatively impact the crucial abilities mentioned above that are required at school or work.

Last but not least, being able to manage and direct our attention effectively is of utmost importance for our well-being. For instance, if you can't focus properly while driving, there's a high risk of accidents.

There are just a few examples that attest to how important attention is for our well-being and success.

Developmental and Clinical Context

It is important to note that attention capabilities aren't set in stone. They can change depending on age and medical conditions.

Children, for example, gradually develop attention and executive control through adolescence. Namely, sustained attention gradually develops from early to late adolescence and matures in adulthood. On the other hand, selective attention is already mature by early adolescence. Because of this, it's important to invest time in cognitive development early on. Then, as we age, some aspects of attention may decline.

Furthermore, attention problems can be linked to specific medical conditions like Attention Deficit Hyperactivity Disorder (ADHD), traumatic brain injury, autism spectrum disorder, and dementia, among others.

How Mendi Neurofeedback Can Improve Attention

Mendi is a neurofeedback device backed by cognitive neuroscience that uses functional near-infrared spectroscopy (fNIRS) to measure brain activity, particularly in the prefrontal cortex, the region responsible for executive functions such as focus, planning, emotion regulation, and attention control.

Neurofeedback works by training the brain to self-regulate. It takes advantage of the brain's neuroplasticity, meaning its ability to reorganize and adapt, as well as to a learning technique called operant conditioning (we're more likely to repeat behaviors associated with positive outcomes).

Mendi’s approach is unique because it translates brain activity into real-time visual feedback through an app. In other words, while you wear the headband, you have to play a game on our app. When you are focused enough, your prefrontal cortex activity increases, the sensors in our headband register this increase, and the ball on the screen rises: you basically control the game with your brain! When you lose focus, the ball drops. This is a positive/negative feedback loop that teaches the brain to reproduce behaviors associated with positive feedback.

With consistent use, this practice strengthens neural pathways associated with attention and concentration, making it easier to sustain focus and shift attention when necessary.

The Prefrontal Cortex and Its Role in Attention

The prefrontal cortex (PFC) is the part of the brain located just behind the forehead. Often described as the brain’s “executive center,” it plays a crucial role in regulating thoughts, emotions, and behaviors. More importantly, it is the hub for attentional control, meaning that every type of attention relies on healthy functioning of this region, as well as other brain regions.

Benefits of Mendi Neurofeedback for Attention

• Faster reaction time. Training the prefrontal cortex with neurofeedback can sharpen different cognitive skills, including your ability to process information quickly. Mendi users often experience quicker responses in everyday situations, whether reacting to traffic while driving, answering questions in class, or making decisions in high-pressure work environments.

• Longer focus endurance. Mendi can strengthen your brain’s capacity to sustain attention for extended periods, potentially lengthening your attention span. This translates to being able to pay attention for a long period during meetings, study sessions, or creative projects without the usual dips in concentration.

• Enhanced ability to avoid distractions. By reinforcing attentional control networks, neurofeedback can help your brain learn how to filter out irrelevant stimuli more effectively. This means fewer interruptions from loud noise, notifications, or wandering thoughts, leading to greater productivity and enhanced ability to effectively manage attentional resources.

• Improved stress management and lower cognitive load. Stress consumes mental energy, which can affect your ability to maintain attention. Mendi training can promote better emotion regulation and enhance stress management skills, allowing the brain to stay calm under pressure. This can reduce cognitive load, freeing up resources for problem-solving, decision-making, and sustained focus.

• Enhanced mental flexibility. Regular practice with Mendi can improve your ability to switch between tasks smoothly and adapt quickly to changing demands.

• Better self-regulation and impulse control. By strengthening executive function, Mendi can help you resist impulsive behaviors and emotional responses, like checking a phone mid-task or abandoning a project prematurely. This can also promote better mental health.

How to Use Mendi for Attention Training

Mendi was designed with user-friendliness in mind. It is fun, interactive, and rewarding! Here are some tips to get you started:

• Consistency is key: short, frequent sessions (3-5 times per week) are recommended; neurofeedback does not work if not practiced long-term because it takes time for new neural pathways to become strong enough for lasting changes.

• Start small: don't overtrain your brain; start with 3-minute sessions three times a week and then gradually increase session duration and frequency.

• Pair with good habits: neurofeedback is most effective when combined with healthy lifestyle practices such as adequate sleep, balanced nutrition, and regular exercise (see more details below).

• Track progress: the Mendi app allows you to visualize improvements in prefrontal cortex activity over time, making attention training both engaging and motivating.

Lifestyle Strategies Beyond Mendi

Neurofeedback training is just one example of an activity that can help you manage your attentional resources better. In addition to neurofeedback training, several lifestyle habits and practices are proven to support and enhance attentional capacities:

• Physical exercise: regular aerobic exercise improves blood flow to the brain and neuroplasticity, boosting attention, memory, and executive function. Even moderate daily activity supports sustained and selective attention.

• Nutrition and hydration: a nutritious diet rich in omega-3 fatty acids, vitamins, minerals, and antioxidants is of utmost importance for brain health. Furthermore, staying hydrated is also important, as dehydration can impair concentration, processing speed, and other cognitive functions.

• Sleep hygiene: adequate, quality sleep underpins all cognitive processes, including attention. Sleep consolidates memories and refreshes the brain’s capacity for focus, making good sleep hygiene critical for sustained and selective attention.

• Mindfulness and meditation: besides neurofeedback, mindfulness meditation remains one of the most effective methods to train attention. It enhances present-moment awareness and reduces susceptibility to distraction.

• Structured routines: create a daily schedule designed to minimize distractions. This can reinforce attentional control by reducing cognitive load and decision fatigue.

Final Thoughts

Ultimately, attention is more than just focus. It’s the foundation of productivity, safety, learning, and well-being. We live in an age that forces our minds to be constantly pulled in a hundred directions. Because of this, it is of the essence to learn to take back control of our attention. This is, in fact, one of the most powerful investments you can make in yourself.
