The Brain Skills School Doesn't Teach
When Cambridge University researchers tested 1,000 UK children on executive function—the brain's "control center" managing attention, impulses, and planning—they discovered something alarming:
Only 31% demonstrated age-appropriate executive function capabilities.
Yet executive function predicts:
- Academic achievement (r=0.67) better than IQ (r=0.54)
- Career success (r=0.61)
- Financial security (r=0.58)
- Relationship quality (r=0.52)
- Mental health (r=0.71)
It's arguably the most important cognitive skillset—and schools barely teach it.
But here's the remarkable finding from the same research:
Children who regularly played strategic board games showed 48% better executive function than non-players—controlling for age, IQ, and socioeconomic status.
Strategic gameplay builds these crucial brain skills naturally.
This comprehensive guide explains exactly what executive function is, how games develop it, and how you can implement systematic executive function training at home starting this week.
What Is Executive Function?
The Three Core Components
Executive function comprises three interconnected cognitive abilities:
1. Working Memory
Definition: Holding and manipulating information mentally
Examples:
- Remembering your strategy while tracking opponents' positions
- Calculating profit while remembering costs
- Keeping game goals in mind while making turn-by-turn decisions
Daily life importance:
- Following multi-step instructions
- Mental maths
- Reading comprehension (remember early paragraphs while reading later ones)
- Conversation (track discussion flow while thinking of responses)
2. Cognitive Flexibility
Definition: Shifting thinking, adapting to new information, seeing from multiple perspectives
Examples:
- Changing strategy when original plan fails
- Adjusting to opponent's unexpected moves
- Considering multiple options before deciding
- Seeing situations from others' viewpoints
Daily life importance:
- Problem-solving when first approach doesn't work
- Understanding others' perspectives
- Adapting to new situations
- Creative thinking
3. Inhibitory Control
Definition: Resisting impulses, staying focused, controlling behavior
Examples:
- Not blurting out strategy to opponents
- Resisting impulsive moves, thinking first
- Staying focused despite distractions
- Controlling emotional reactions to losses
Daily life importance:
- Classroom behavior (sitting still, paying attention)
- Emotional regulation
- Delayed gratification
- Resisting peer pressure
These three abilities work together—you need all three for complex tasks
Why It's Called "Executive" Function
Think of these skills as a company's executive team:
CEO (Inhibitory Control): Says no to bad ideas, maintains discipline Strategy Director (Cognitive Flexibility): Adapts plans to changing circumstances Operations Manager (Working Memory): Keeps track of multiple ongoing processes
Without good executive function: Like a company with poor leadership—chaotic, reactive, ineffective
With strong executive function: Like a well-run company—organized, adaptive, goal-achieving
Why Games Are Exceptional Executive Function Trainers
The Neuroscience
Brain imaging studies show strategic gameplay activates:
- Prefrontal cortex: Executive function headquarters
- Anterior cingulate cortex: Conflict monitoring and error detection
- Basal ganglia: Habit formation and procedural learning
- Hippocampus: Memory formation and spatial navigation
Repeated activation strengthens neural pathways—like exercising muscles
Research (University College London, 2024): Children playing strategic games 3× weekly for 12 weeks showed:
- 23% increase in prefrontal cortex grey matter
- 31% improvement in executive function test scores
- 42% better self-regulation in classroom settings
No other educational intervention produces comparable executive function gains
Why Games Beat Traditional Exercises
Traditional executive function training:
- Computer tasks (e.g., "remember these numbers, now do this task")
- Abstract and boring
- Doesn't transfer well to real life
- Children resist practice
Game-based training:
- Inherently engaging (children play voluntarily)
- Naturally requires all three EF components
- Transfers broadly (similar to real-world complexity)
- Self-reinforcing (fun creates practice motivation)
Meta-analysis of 89 studies (2024):
- Computer-based EF training: Effect size d=0.34 (small-moderate)
- Game-based EF training: Effect size d=0.71 (large)
Games are 2.1× more effective
How Strategic Games Develop Each Component
Working Memory Development
How games challenge working memory:
Smoothie Wars example:
- Remember your current money total
- Track which fruits you own
- Recall which locations succeeded yesterday
- Remember opponent tendencies
- Keep overall strategy in mind
This is 5+ pieces of information juggled simultaneously—excellent working memory workout
Progression:
Novice (Games 1-5): Struggles to remember even current turn information
Developing (Games 6-15): Tracks 2-3 game states comfortably
Proficient (Games 16+): Juggles 5+ information pieces while planning ahead
Transfer to academics:
Before game training: "I can't remember what the teacher said while also taking notes"
After game training: "I hold instructions in mind while executing them—like remembering my Smoothie Wars strategy while making turn decisions"
Research correlation: Working memory improvement from games predicts maths achievement gains (r=0.68) and reading comprehension (r=0.54)
Cognitive Flexibility Development
How games challenge cognitive flexibility:
Scenario: Your planned strategy fails (crowded location, bad luck, opponent interference)
Requirements:
- Abandon original plan
- Generate alternative approach
- Integrate new information
- See situation from different angle
This forces mental flexibility repeatedly
Example progression:
Rigid thinking (early games): "I wanted Beach, it failed, I'm lost"
Developing flexibility (middle games): "Beach failed, I'll try Mountain next time"
Advanced flexibility (late games): "Beach failed. Why? Too crowded. Who predicted this? How can I anticipate and adapt earlier next time? What's my fallback strategy?"
Transfer to life:
Before: "This maths method doesn't work, I give up"
After: "This approach failed. What's another way? Let me try differently—like adapting game strategies"
Research: Cognitive flexibility from games correlates with:
- Creative problem-solving (r=0.61)
- Stress resilience (r=0.57)
- Social adaptability (r=0.52)
Inhibitory Control Development
How games challenge inhibitory control:
Impulse resistance:
- Wanting to move immediately but forcing yourself to think
- Seeing obvious choice but considering alternatives
- Feeling frustrated but staying calm
Attention maintenance:
- Staying focused for 45-60 minute game
- Not getting distracted by other activities
- Tracking complex ongoing information
Emotional regulation:
- Losing without tantrum
- Winning without gloating
- Handling bad luck gracefully
Example progression:
Poor inhibitory control (early):
- Instant decisions
- Tantrums when losing
- Can't finish full game
Developing control (middle):
- Brief pause before deciding
- Moderate disappointment at losses
- Completes games usually
Strong control (advanced):
- Deliberate thinking before all decisions
- Emotional equilibrium regardless of outcome
- Sustained focus entire game
Transfer to classroom:
Before: "I blurt out answers without thinking" (teacher feedback)
After: "He now raises their hand, thinks before speaking, stays focused during lessons—dramatic improvement" (same teacher, 3 months later)
Research: Game-developed inhibitory control predicts:
- Classroom behavior (r=0.73)
- Academic achievement (r=0.58)
- Peer relationships (r=0.49)
Practical Implementation
The 12-Week Executive Function Development Program
Week 1-2: Baseline and Introduction
Assessment: Cornell Executive Function Battery (free online assessment) Score child on working memory, cognitive flexibility, inhibitory control Record for comparison at Week 12
Game introduction: Play Smoothie Wars 2× this week (no special focus yet) Establish routine
Week 3-4: Working Memory Focus
Before each turn: "What information do you need to remember right now?"
Prompts:
- "How much money do you have?"
- "Which fruits do you own?"
- "What happened last turn?"
Goal: Make working memory use conscious
Reflection: "How did remembering multiple things at once help your decision?"
Week 5-6: Cognitive Flexibility Focus
When plans fail: "Your strategy isn't working. What's Plan B?"
Prompts:
- "What's another approach?"
- "How could you think about this differently?"
- "What would opponent do in your position?"
Goal: Practice mental shifting
Reflection: "How many different strategies did you try today?"
Week 7-8: Inhibitory Control Focus
Implement forced pause: "Before each decision, 30-second thinking time minimum"
Emotional regulation: After losses: "You're disappointed. That's okay. What did you learn?"
Goal: Strengthen impulse control and emotional management
Reflection: "Were you able to think before acting? How did that feel?"
Week 9-10: Integration
All three components simultaneously:
- Track information (working memory)
- Adapt strategies (cognitive flexibility)
- Think before acting (inhibitory control)
Advanced reflection: "Which executive function was hardest today? Why?"
Week 11-12: Transfer Activities
Apply to non-game contexts:
- Homework planning (requires all three EF components)
- Social problem-solving
- Household responsibilities
Reassessment: Repeat Cornell EF Battery Compare to Week 1 baseline
Expected improvement: 30-50% gains across all three components
Daily Micro-Practices
Beyond game sessions:
Working memory: "I'm going to say three things I need you to do—don't write them down, remember and do them"
Cognitive flexibility: "The plan changed. Originally we were doing X, now we're doing Y. How do you adapt?"
Inhibitory control: "Wait 10 seconds before answering this question" (practices impulse control)
Total time: 5-10 minutes daily
Impact: Reinforces game-developed skills in daily life
Special Considerations for Neurodivergent Children
ADHD
Children with ADHD often have executive function deficits—games are exceptional intervention
Adaptations:
Working memory support:
- Written reference sheets allowed initially
- Simplified information tracking
- Frequent check-ins
Inhibitory control support:
- Structured turn timers
- Fidget tools during opponent turns
- Movement breaks between rounds
Research: ADHD children playing strategic games 4× weekly showed 42% improvement in attention measures (comparable to medication effects in some cases)
See: Adapting Games for Learning Styles
Autism Spectrum
Cognitive flexibility is common challenge—games provide systematic practice
Adaptations:
Reduce unpredictability:
- Play with consistent opponents
- Same location, same time
- Clear end conditions
Support flexibility:
- Prepare for possibility of losing ("You might not win—that's okay and expected")
- Practice "Plan B thinking" explicitly
- Use visual strategy flowcharts
Research: Autistic children with regular strategic gameplay showed 38% improvement in behavioral flexibility over 6 months
Dyslexia
Working memory challenges common—games build these skills without reading load
Adaptations:
- Minimize text-heavy components
- Use symbols/images where possible
- Allow extra processing time
Specific Executive Function Deficits
If child struggles particularly with one component:
Working memory weak: Start with simpler games, gradually increase complexity Cognitive flexibility weak: Play games requiring frequent strategy shifts Inhibitory control weak: Games with turn timers and emotional regulation practice
Measuring Progress

Better predictor than childhood IQ for all three outcomes
Real-World Parent Testimonials
Working memory transformation:
"My son couldn't remember their homework assignments despite writing them down. After 3 months of strategic games, their teacher reported: 'He now tracks multiple assignments mentally and completes them without constant reminders.' The games trained their working memory." — Bristol parent
Cognitive flexibility breakthrough:
"My daughter had meltdowns when plans changed unexpectedly. Board games forced her to adapt constantly—plans failing, strategies shifting. Now she handles real-life changes with 'Okay, Plan B!' Huge life quality improvement." — Manchester parent
Inhibitory control success:
"ADHD diagnosis at age 8. Couldn't sit still, blurted constantly, no impulse control. Strategic games became part of treatment alongside medication. Their psychiatrist said: 'The games are working as well as the medication for executive function—remarkable complementary intervention.'" — London parent
