Short answer: Executive function skills help you hold information in mind, manage your responses and adapt when plans change. In adult life, those skills contribute to planning, starting and following through. A useful first step is to choose one everyday difficulty, try a practical support and check whether it helps that specific task.
You can run a meeting and still leave a personal email unanswered for a week. You can care about a project and struggle to decide what to do next. Those moments are worth understanding, but they don't tell you why they're happening on their own.
Start with something you can observe. Instead of "I'm terrible at managing my life," try "I keep forgetting the follow-up after a meeting." That's specific enough to work with.
What are executive function skills?
Researchers commonly describe three core executive functions: working memory, inhibitory control and cognitive flexibility. Adele Diamond's review explains how these processes contribute to purposeful thinking and action.
- Working memory: holding information in mind while using it. For example, keeping the next instruction in mind while you complete the current step.
- Inhibitory control: managing a response or distraction so you can stay with what you intended to do. For example, pausing before switching to a new notification.
- Cognitive flexibility: adjusting your approach when circumstances change. For example, revising your plan when a meeting runs late.
These are processes, not personality types. Everyday activities such as organizing a project can involve several at once. You don't need to decide which label fits perfectly before trying a clearer instruction or a useful reminder.
How do executive function demands show up at work and home?
Look at one recent situation rather than rating your whole life. The examples below are starting points for reflection, not a checklist that diagnoses a condition.
| Situation | A question to ask | A support to try |
|---|---|---|
| You leave a meeting and forget the follow-up | Where did the next action get recorded? | Put the action and its deadline in the same place before leaving. |
| A project stays on your list without moving | Is the first action concrete enough to do? | Replace "work on proposal" with "write three draft headings." |
| Your day fills up before the priority gets attention | Did the plan include your actual commitments? | Put fixed commitments on the calendar before choosing another task. |
| An interruption makes it hard to return | Can you tell where you stopped? | Leave a short restart note before switching tasks. |
| A changed plan leaves you stuck | What is still possible with the time you have? | Choose a smaller useful outcome for the remaining time. |
Notice where things already work. If you reliably follow through when an appointment is on your calendar, that gives you something concrete to test elsewhere. It doesn't mean you need to rebuild every routine.
What can you try when remembering isn't enough?
External reminders are one practical option. In four online experiments, Sam Gilbert found that participants performed better on delayed-intention tasks when they could set reminders. Those tasks involved short delays, so the findings don't establish that any particular calendar system will solve everyday planning difficulties. Read the original study.
A 2025 study by Pei-Chun Tsai and Sam Gilbert also found that reminders improved accuracy on experimental time-based tasks. The study tested short delays and simple responses, not a coaching program or long-term workplace outcomes.
The practical question is small: would an external cue help you complete this particular action?
Try a reminder that names both the action and the material you need: "Open the budget sheet and check the travel total." Put it where you'll encounter it when you're able to act. If it fires during another meeting, change the timing before deciding the whole approach failed.
For a task you remember but keep postponing, a different adjustment may be worth testing. Our guide to getting started when a task feels difficult explores that situation in more detail.
What would a small experiment look like?
Here's a hypothetical example, not a client story or a promised result.
You want to submit an expense claim on Friday. "Do expenses" has been sitting on your list, but you haven't gathered the receipts.
Make the next action visible
Write: "Open the receipts folder and identify the items from this week." Choose a time when you can access the folder. Keep the reminder with the link or location of the receipts.
Define a manageable result
For the first attempt, your target could be gathering the receipts. If that goes smoothly, continue. If it doesn't, note what stopped you: missing information, an interruption, an unclear next step or a time slot that wasn't available.
Review what happened
After the attempt, record three things:
- Did I notice the reminder?
- Did I begin the action I'd written down?
- What should I keep or change next time?
Suppose you noticed the reminder but couldn't find two receipts. A more useful next experiment might be saving receipts as they arrive. Another alert wouldn't address the missing information.
This exercise is a way to compare attempts. It isn't a validated assessment or a test of your motivation.
Can practice improve executive function?
Be specific about what "improve" means. Completing a recurring task with a checklist is a useful outcome. It doesn't, by itself, show that working-memory capacity or executive function has improved generally.
Research also distinguishes improvement on a practised task from improvement on very different tasks. A 2023 review by Fernand Gobet and Giovanni Sala questions broad transfer claims made for cognitive training. That review isn't a study of Kaizen coaching, and it shouldn't be used to promise or rule out a particular person's results.
For your own experiment, measure the outcome you actually care about: sending the follow-up, bringing the right materials or beginning the planned work. Use those observations to decide what to adjust. You don't need to claim a brain change to recognize a useful practical change.
When might coaching be useful?
If you'd like help choosing an approach and reviewing what happens, you can explore Kaizen's adult executive function coaching. The adult program begins with the Cognitive Architectural Profile and a one-on-one results review, then builds coaching around your profile and goals.
A consultation is a chance to discuss what you're finding difficult and ask about the program. You can bring an ordinary example, such as the unfinished expense claim, rather than a polished explanation of what's wrong.
Coaching focuses on practical goals and strategies. This article doesn't diagnose the reason for a difficulty or replace appropriate clinical care.
How can the adult Executive Function Assessment help you reflect?
Our free Executive Function Assessment asks 50 questions about 14 skills across four areas. Allow about 10 minutes. It is a separate questionnaire from the practical exercise in this guide.
Use the profile as a prompt to compare your answers with everyday examples. Which strengths do you already rely on? Which situation would you like to make easier? Choose one small change to try and notice what happens, rather than treating a score as a verdict about your ability.
The questionnaire is an educational self-reflection tool, not a diagnosis or clinical assessment. It cannot establish why a task is difficult or replace care from a qualified professional.
Common questions
Is this an executive function test?
No. The examples and exercise are prompts for reflection, not a diagnostic test or a validated measure of executive function. They cannot tell you why a difficulty is happening.
Do I need a new app to try this?
You can start with paper or a tool you already use. Choose a place for the next action and a cue you will encounter when you can act. Then check whether that arrangement helped with the task.
How will I know whether a strategy is helping?
Choose one observable outcome, such as sending a follow-up or starting a planned task. Compare what happened across attempts and record what changed. Progress on that task does not by itself establish a general change in executive function.
