This is the third article in an eight-part series exploring the core executive functions and how ADHD affects them. Non-verbal working memory, an essential executive function, plays a critical role in how we process visual and sensory information, remember past experiences, and manage time effectively.
For individuals with ADHD, challenges with non-verbal working memory can lead to difficulties visualizing the future, staying on schedule, or learning from past mistakes.
In this article, we’ll break down how non-verbal working memory works, how ADHD impacts it, and practical strategies to strengthen this skill.
What Is Non-Verbal Working Memory?
Non-verbal working memory is the brain’s ability to temporarily hold and manipulate visual and sensory information. It helps us:
Create mental images of past experiences or future events.
Track time and understand its passage.
Use sensory input to guide decision-making.
In simpler terms, non-verbal working memory allows you to “see” in your mind’s eye—whether it’s remembering where you left your keys or visualizing how to assemble furniture from a manual (Barkley, 2012).
Why Is Non-Verbal Working Memory Important?
Non-verbal working memory is essential for:
Time Management: It helps us estimate how long tasks will take and plan accordingly.
Problem-Solving: Visualizing outcomes allows us to foresee potential consequences and make better decisions.
Learning from Experience: Remembering past mistakes or successes helps us adapt and improve.
Navigation and Organization: Using mental maps to recall where things are or how to get from point A to B.
Without non-verbal working memory, it’s challenging to connect past, present, and future experiences, which is crucial for effective planning and self-regulation.
How ADHD Impairs Non-Verbal Working Memory
ADHD directly affects the brain’s ability to retain and use non-verbal information, leading to several key challenges:
1. Difficulty Visualizing the Future
ADHD brains often struggle to hold a mental image of future goals or deadlines. This can make it hard to prioritize tasks or feel motivated to act on long-term plans (Barkley, 2012).
2. Poor Time Awareness
Many people with ADHD experience “time blindness,” where time feels abstract or difficult to track. Without a clear mental representation of time, tasks may feel equally urgent or completely disconnected from their deadlines.
3. Forgetting Past Experiences
ADHD can impair the ability to use past experiences to inform current decisions. For example, someone may repeatedly forget how long it takes to get ready in the morning, leading to chronic lateness.
4. Challenges with Visual-Spatial Tasks
Difficulties holding mental images can impact everything from following directions to organizing physical spaces like desks or closets.
Why ADHD Behaviors Can Seem Disorganized or Inconsistent
Impaired non-verbal working memory often manifests in ways that appear disorganized or careless to others. For example:
Forgetting Commitments: Difficulty holding visual reminders in mind can lead to missed appointments or tasks.
Underestimating Time: Without a clear sense of how long tasks take, individuals with ADHD may often run late or overcommit.
Struggling to Plan: Inability to “see” the steps required to achieve a goal can make planning feel overwhelming.
These behaviors aren’t due to laziness or lack of care—they’re rooted in neurological differences in how information is processed.
Strategies to Strengthen Non-Verbal Working Memory in ADHD
While non-verbal working memory challenges are common in ADHD, there are practical strategies to improve this skill and compensate for its weaknesses:
1. Use Visual Aids
External visual supports can help bridge gaps in non-verbal working memory. Examples include:
Calendars and planners to track deadlines.
Sticky notes or whiteboards for reminders.
Visual timers to represent time passing.
2. Break Tasks into Smaller Steps
Create a step-by-step visual plan for tasks. For example:
Write out the steps to prepare for work in the morning.
Use checklists to track progress on projects.
Breaking tasks into manageable pieces makes them easier to visualize and execute.
3. Practice Visualization Exercises
Develop your mental imagery by practicing visualization. For example:
Close your eyes and picture yourself completing a task, like arriving on time for an appointment.
Imagine the steps required to achieve a goal, such as cleaning a room.
Over time, this can improve your ability to hold mental images.
4. Use Time Anchors
Anchor tasks to specific times of day. For example:
Instead of saying, “I’ll do this later,” set a concrete time, like “I’ll start at 3 p.m.”
Pair tasks with daily routines, such as responding to emails right after breakfast.
Time anchors create structure and help combat time blindness.
5. Incorporate Physical Cues
Leverage physical objects to support non-verbal working memory. For example:
Place items you need to bring with you (e.g., keys, wallet) in a designated spot.
Use color-coded folders or bins to organize tasks visually.
6. Set Alarms or Timers
Digital reminders can act as external memory aids. Alarms or timers can help with task transitions, deadline tracking, or staying on schedule.
Final Thoughts
Non-verbal working memory is a crucial executive function that connects our past, present, and future. For individuals with ADHD, impairments in this area can lead to challenges with time management, organization, and planning. However, with intentional strategies and external supports, it’s possible to improve these skills and navigate life more effectively.
