Divided attention refers to the ability to focus on multiple tasks or stimuli simultaneously.

What is divided attention?

Divided attention, often referred to as multitasking, is the capacity to manage focus across multiple activities or inputs at the same time.

It is a vital cognitive skill that allows individuals to process various pieces of information simultaneously, such as talking while driving or listening to music while working.

Unlike selective attention, which focuses on filtering and prioritising a single source of information, divided attention requires managing limited mental resources across several tasks.

Why divided attention matters in modern life

In the fast-paced digital world, divided attention is an essential skill.

With constant exposure to notifications, emails, and social media, individuals are often compelled to juggle multiple tasks.

This skill impacts productivity, learning, and even personal safety.

For example, attempting to text while driving divides cognitive resources, increasing the likelihood of errors or accidents.

Developing an understanding of divided attention can help improve focus and minimise the risks of task overload.

The psychology behind divided attention

Divided attention is rooted in cognitive psychology and neuroscience.

It highlights the brain’s limited capacity to process information.

When individuals engage in two or more activities simultaneously, the brain splits its resources between these tasks.

This process can lead to decreased performance on one or all activities.

Research has shown that multitasking often involves rapid task-switching rather than true simultaneous focus.

This constant switching can impair cognitive performance and increase mental fatigue.

Factors influencing divided attention:

• Task complexity: Complex tasks require more cognitive resources, making it harder to divide attention effectively.
• Practice and familiarity: Repeated exposure to a task can make it automatic, reducing the cognitive load and allowing better multitasking.
• Age and cognitive capacity: Young adults generally have better multitasking abilities than older adults due to higher working memory and processing speed.

Divided attention vs. selective attention

While both divided and selective attention are essential, they serve different purposes.

Selective attention involves focusing entirely on a single task or stimulus while ignoring distractions.

For example, reading a book in a noisy room requires selective attention to block out background noise.

Divided attention, on the other hand, aims to manage focus across multiple inputs simultaneously.

It is important to recognise that attempting to split attention often leads to reduced efficiency compared to focusing on one task at a time.

Common challenges of divided attention

Divided attention can lead to several challenges in daily life.

Reduced productivity

Research indicates that multitasking can reduce productivity by up to 40%.

This occurs because the brain expends additional effort to switch between tasks, leading to slower performance and increased errors.

Increased stress

Attempting to juggle multiple tasks can increase cognitive load, resulting in higher stress levels and mental exhaustion.

Safety risks

Divided attention can compromise safety in critical situations, such as driving or operating machinery.

Distracted driving, for instance, is a leading cause of road accidents globally.

Can you really multitask?

While many people believe they are skilled multitaskers, research suggests otherwise.

Studies show that humans have a limited capacity for simultaneous task management.

Multitasking often involves rapid switching between tasks, which consumes additional cognitive resources and reduces overall efficiency.

Certain tasks, however, become easier to multitask with practice.

For example, experienced drivers can converse or listen to the radio without compromising their driving performance.

How to improve divided attention

Improving divided attention involves developing cognitive flexibility and reducing distractions.

Practical strategies:

• Prioritise tasks: Focus on high-priority tasks and address them one at a time when possible.
• Minimise distractions: Reduce external interruptions by creating a quiet work environment or using tools like noise-cancelling headphones.
• Practice dual-tasking: Gradually introduce simple multitasking exercises, such as walking while solving mental puzzles.
• Strengthen working memory: Activities like reading, puzzles, and memory games can enhance cognitive capacity.
• Take breaks: Regular breaks help prevent mental fatigue, improving overall focus.

Suggested activities to enhance divided attention:

• Playing games like Sudoku or chess that require planning and focus.
• Listening to audiobooks while performing light physical activities like walking.
• Engaging in interactive tasks, such as cooking while following a recipe.

Divided attention across the lifespan

Divided attention capabilities change with age.

In children

Young children struggle with divided attention as their cognitive systems are still developing.

They benefit from tasks that focus on selective attention and gradually introduce multitasking elements.

In adults

Young adults often excel in divided attention due to better working memory and processing speed.

This ability peaks in early adulthood and starts to decline in middle age.

In older adults

Older adults may face challenges in multitasking due to age-related declines in cognitive flexibility and memory.

Training exercises can help mitigate these effects and improve attention skills.

Divided attention in academic and workplace settings

Divided attention plays a critical role in academic and professional environments.

Academic success

Students often need to multitask, such as listening to lectures while taking notes.

Effective multitasking strategies, such as pre-organising notes, can improve learning outcomes.

Workplace productivity

In the workplace, managing divided attention can enhance productivity and reduce errors.

Using tools like project management software and setting clear priorities can help professionals manage multiple tasks efficiently.

The neuroscience of divided attention

Neuroscience provides insights into the brain mechanisms behind divided attention.

Key brain regions, such as the prefrontal cortex, play a role in managing cognitive resources and task switching.

Research using functional MRI (fMRI) scans reveals that multitasking increases activity in the brain’s executive control network.

This heightened activity explains why multitasking can be mentally draining over time.

Conclusion

Divided attention is a valuable cognitive skill but comes with limitations.

Understanding the challenges and applying practical strategies can enhance multitasking abilities while minimising risks.

By focusing on cognitive flexibility, reducing distractions, and practising regularly, individuals can improve their capacity for divided attention and thrive in a multitasking world.

Mental clarity is essential for better decision-making, improved focus and reduced stress — and it doesn’t have to be a challenge to achieve.

While many people think focus requires complicated techniques, some surprisingly simple habits can have an immediate effect.

With small, actionable changes you can sharpen your focus and reduce stress almost instantly.

These habits may be unexpected, but their effects are both profound and immediate.

Why not try them today and see how quickly your mind becomes clearer and more productive?

1. Chewing Gum: A Surprising Brain Stimulator

You might not associate chewing gum with productivity, but research has shown that this everyday activity can significantly improve mental clarity.

For example, a study by Morgan et al. (2013) tested the audio memory of those chewing gum, compared with those who didn’t.

The gum chewers had improved short-term memory compared with non-chewers, suggesting they were paying more attention.

How Does Chewing Gum Work?

• Boosts Blood Flow to the Brain
  The act of chewing increases heart rate and blood flow, delivering more oxygen and nutrients to your brain.
• Activates Memory and Focus Regions
  Studies have linked chewing gum to enhanced activity in the hippocampus, a part of the brain essential for memory and learning.
• Reduces Stress and Anxiety
  Chewing gum lowers cortisol levels, the hormone responsible for stress, which can cloud your thinking.

How to Incorporate This Habit

• Choose sugar-free gum to protect your teeth and overall health.
• Chew during tasks that require sustained concentration, such as studying or completing work projects.
• Use it sparingly, as constant chewing can lead to jaw fatigue.

With this small change, you can improve your focus and reduce feelings of mental fog almost instantly.

2. Decluttering Your Desk: The Power of a Tidy Space

Your physical environment has a direct impact on your mental state.

A cluttered desk creates unnecessary stress and divides your attention, while an organised space fosters a sense of control and clarity.

Why Does Decluttering Work?

• Reduces Cognitive Overload
  Visual clutter forces your brain to process too much information at once, which can make you feel scattered.
• Boosts Productivity
  A clean, organised workspace allows you to focus fully on your priorities.
• Improves Emotional Well-being
  Tidying up reduces stress and helps you feel calmer and more in control of your environment.

Simple Steps to Declutter

• Take just five minutes at the start or end of each day to tidy your workspace.
• Remove unnecessary items from your desk and keep only the essentials, such as your computer, notebook, and a water bottle.
• Add a calming element like a small plant or a minimalistic organiser to create a more inviting environment.

A clean workspace can have an immediate and lasting effect on your ability to think clearly and perform effectively.

Bear in mind, though, that research has also found that clean desks encourage people to do what is expected of them (Vohs et al., 2013).

However, messy desks enhance the ability to come up with new ideas — so if that is your primary aim then decluttering might be mistake!

Why These Habits Are Effective

Both chewing gum and decluttering tackle common barriers to mental clarity in unique ways.

Chewing gum stimulates physical changes in the brain that promote focus, while decluttering removes external distractions that drain mental energy.

These habits are simple, accessible, and require very little time or effort.

By incorporating them into your routine, you can regain mental clarity whenever you feel distracted or overwhelmed.
