Working memory is your brain's ability to hold and manipulate information in the moment. It allows you to remember the first half of a sentence while reading the second, keep track of next steps in a meeting, and juggle multiple tasks without losing focus.
Unlike long-term memory, working memory is limited and highly sensitive to distractions. Think of it as your mental "RAM." It is essential for decision-making, problem-solving, and productivity at work.
"...Life comes at us, and it comes at us very quickly, and what we need to do is to take that amorphous flow of experience and somehow extract meaning from it with a working memory that's about the size of a pea." - Educational Psychologist, Peter Doolittle
Why working memory matters for work
Strong working memory helps you:
Follow complex conversations without missing details
Prioritize tasks and avoid dropping action items
Stay focused when switching between projects
Turn meetings into clear, actionable next steps
For example, think about a sprint planning session where tasks are flying around the room. Strong working memory helps you keep track of what was just discussed while anticipating the next point. Or consider a client call where expectations are laid out quickly. It makes the difference between leaving with a clear list of deliverables versus trying to reconstruct the details from memory later.
When working memory is low, you may notice:
Forgetting details right after hearing them
Losing track of tasks midway through
Struggling to prioritize or organize information
What impacts working memory?
Several factors influence how well your working memory functions:
Stress and overload: Too much input can overwhelm your mental bandwidth. When three Slack threads, a Linear update, and a Zoom call all hit at once, your brain struggles to decide what deserves focus.
Sleep and rest: A tired brain struggles to hold onto information. Late-night work or skipping breaks can reduce recall the next day.
Environment: Constant interruptions reduce your ability to focus. If you are trying to absorb a design review while monitoring email pings, your verbal memory is already working at a disadvantage.
Tools and systems: Relying on memory alone to manage tasks adds unnecessary strain. Without support, important details from a meeting or brainstorm are easy to lose.
Researchers often explain these challenges through Baddeley's Model of Working Memory, one of the most widely used frameworks. It describes four components that work together:
Central Executive: Directs attention and focus. Stress or heavy multitasking can overload this system, making it harder to prioritize.
Phonological Loop: Handles verbal and auditory information. Distractions during a conversation reduce its efficiency.
Visuospatial Sketchpad: Manages visual and spatial data. Fatigue makes it harder to process diagrams, designs, or layouts.
Episodic Buffer: Integrates information from different inputs and links it to long-term memory. Overload here weakens your ability to connect new ideas with what you already know.
How to improve working memory
The good news: working memory is not fixed. You can strengthen it with the right habits and systems.
1. Reduce cognitive load
You have probably heard this before: write things down instead of juggling them in your head. Offloading information frees up mental space for deeper thinking. With apps like Supernormal, action items from your calls are captured and organized automatically, so you can focus on the conversation itself.
2. Improve memory at work with structured systems
Use tools that automatically capture and organize meeting notes, tasks, and follow-ups. This prevents important details from slipping through. For example, instead of trying to remember who owned a task from your weekly standup, you can review the notes Supernormal captured and move directly to execution.
This approach is part of what many call personal knowledge management: creating a reliable system outside your brain to store, organize, and retrieve important information. A good PKM system strengthens your working memory by making sure you always know where to find details, projects, and ideas when you need them.
3. Strengthen with practice
Exercises like learning a new language, playing memory-based games, or practicing mental math can sharpen your working memory over time. Even structured brainstorming with teammates can provide a workout, as you actively hold and connect multiple ideas at once.
4. Optimize your environment
Limit distractions, block focus time, and keep your workspace clear. Clear desk, clear mind. The same applies digitally: shutting down unused tabs and muting Slack during deep work is the online version of tidying your desk.
5. Prioritize rest and recovery
Adequate sleep, regular breaks, and short walks improve recall and focus. A well-rested brain holds onto information longer. Even a quick reset between meetings can make it easier to recall the discussion later.
Five-Minute Habits to Strengthen Working Memory
Repeat new information out loud to reinforce recall
Sketch a quick diagram of what you just heard
Pause after a meeting to write down two or three key takeaways
Summarize a conversation to yourself in one sentence
Challenge yourself to remember a short list backward and forward
Bringing it back to work
You do not need to rely solely on your brain to remember everything. By understanding what working memory is, recognizing what impacts it, and adopting strategies for how to improve working memory, you set yourself up for sharper thinking and better execution.
Professionals are increasingly relying on external systems to extend their memory. This concept, sometimes called "cognitive offloading," allows you to free up mental space for higher-level thinking.
Tools like Supernormal not only capture your meetings but also organize your knowledge, moving toward a future where your working memory and your digital memory work seamlessly together.
