Working Memory and Work Performance

Why Working Memory Matters for Work

Working memory functions like the brain's "notepad," temporarily holding and processing information. This ability comes into play in virtually every work situation.

Multitasking

The ability to handle multiple pieces of information simultaneously. Examples include taking notes during meetings while understanding the discussion, or managing multiple projects in parallel.

Complex Problem-Solving

The ability to consider multiple aspects of a problem while deriving solutions. Essential for understanding cause-and-effect relationships and selecting optimal solutions.

Information Integration

The ability to organize and integrate information from meetings and discussions for decision-making. Works when grasping the big picture from scattered information.

Understanding and Executing Instructions

The ability to understand complex instructions from supervisors or clients and execute them accurately. Involves remembering multiple elements while prioritizing.

Research on Working Memory and Job Performance

Scientific Evidence

A 2025 systematic review indicates that working memory training may produce transfer effects not only on cognitive functions but also on academic performance. Improvements in mathematics and reading comprehension have particularly been reported.

Additionally, working memory capacity strongly correlates with fluid intelligence, and fluid intelligence has been shown in numerous studies to relate to academic and professional success.

Practical Methods to Improve Focus at Work

Applying Dual N-Back-Trained Attention Control to Work

The "attention switching" and "interference suppression" abilities trained through Dual N-Back are particularly important in modern work environments.

Applying Attention Control to Work

Handling Distractions

In Dual N-Back, you train to track two stimuli (position and audio) simultaneously while ignoring irrelevant information. Apply this to work:

Notice: Become aware that you've been distracted (metacognition)
Evaluate: Determine whether that information is currently important
Return: If not important, consciously return to your task

Making these three steps habitual—like Dual N-Back—helps maintain focus.

Information Management During Multitasking

When handling multiple tasks, continuously "updating" information like in Dual N-Back is key. Release information from completed tasks and incorporate information for new ones.

Combining with the Pomodoro Technique

1
25 Minutes of Focused Work
Set a timer and focus on a single task. Use your Dual N-Back-trained attention control to consciously return to the task when distracted.
2
5-Minute Break
Refresh your brain with a short break. As discussed in fatigue management, appropriate breaks are key to maintaining performance.
3
Longer Break After 4 Sets
After 4 pomodoros (about 2 hours), take a 15-30 minute longer break. A short Dual N-Back session during this time can also be effective.
4
Reflection and Adjustment
At day's end, reflect on when you focused well and which tasks, then apply insights to the next day's planning.

Practicing Deep Work

What is Deep Work?

A concept proposed by Cal Newport, referring to cognitively demanding work performed without interruption. Skills trained through Dual N-Back enhance deep work quality:

Sustained Attention: Maintaining focus for extended periods
Interference Suppression: Blocking out irrelevant stimuli
Working Memory: Manipulating complex information mentally

Using Dual N-Back to Improve Study Efficiency

Dual N-Back as a Pre-Study Warm-Up

Warming Up Your Brain Before Studying

Recommended Routine

Step	Time	Activity
1. Preparation	2 min	Set up study environment, put phone away
2. Dual N-Back	10-15 min	Activate brain at moderate difficulty
3. Transition	3 min	Review material, set goals
4. Begin Studying	-	Start learning in a heightened focus state

Notes

Keep difficulty manageable (around N=2-3) to avoid exhaustion
Too difficult causes frustration, becoming counterproductive
The goal is "activating your brain," not "getting high scores"

Enhancing Learning Retention

Working memory serves as a "gateway" for transferring new information to long-term memory.

Active Recall

Practice recalling content after studying with textbooks closed. Actively using working memory strengthens memory consolidation.

Spaced Repetition

Reviewing at intervals strengthens memory. Makes transfer from working memory to long-term memory more efficient.

Elaboration

Connecting new information with existing knowledge. Uses working memory's ability to manipulate and integrate information.

Chunking

Grouping information into clusters. A technique for efficiently using working memory's limited capacity.

Subject-Specific Applications

Subject	Working Memory Application	Specific Techniques
Mathematics	Following multiple steps simultaneously	Stay aware of the overall solution while solving
Languages	Building sentences while applying grammar rules	Use multiple abilities simultaneously via reading aloud or conversation practice
Reading	Retaining previous context while reading forward	Practice summarizing each paragraph
Programming	Writing code while grasping overall structure	Pseudocode for overall design → detailed implementation

Applications for Task Management and Decision-Making

Building Systems to Support Working Memory

Since working memory has limits, using external tools reduces cognitive load.

1
Reliable Task Management System
Write all tasks in one system (app or notebook). Reducing the burden of remembering everything frees working memory for truly important thinking.
2
Daily Planning
Plan the next day's tasks in the morning or previous evening. Clear priorities reduce the cognitive load of deciding "what to do next."
3
Minimize Context Switching
Process similar tasks together (batch processing). Check emails at set times to reduce attention-switching costs.
4
Regular Reviews
Review progress weekly and improve your systems. Like maintaining training habits, continuously improve your work systems.

Improving Decision Quality

Working Memory and Decision-Making

Complex decisions require simultaneously comparing multiple options and their outcomes. Higher working memory capacity means:

Ability to consider more options
Easier consideration of long-term consequences
More logical judgments less influenced by emotions

However, for important decisions, write things out to compensate for working memory limitations.
