This article explains how to create an effective training plan based on scientific research, for those who understand the basics of Dual N-Back.

Daily Training Duration: What's the Sweet Spot?

Research Shows: 20-25 Minutes is Optimal

Analysis of multiple studies reveals that 20-25 minutes per day is the most effective duration.

Comparison of Research Protocols

Daily training durations used in major studies:

Study	Daily Duration	Period	Results
Jaeggi et al. (2008)	~25 minutes	8-19 days	Fluid intelligence improvement confirmed
Stephenson & Halpern (2013)	20 minutes	20 days	Working memory improvement
PLoS One (2016)	17-25 minutes	5 weeks	Effects confirmed vs. processing speed training
Scientific Reports (2021)	30 minutes	4 weeks	Effects confirmed vs. mnemonic strategies

Duration Ranges and Their Effects

10-15 Minutes

For beginners. Basic effects can be achieved, but may be too short for sufficient cognitive load. Suitable for the first 1-2 weeks of familiarization.

20-25 Minutes (Recommended)

The standard duration used in most research. Ideal balance of maintaining focus while providing adequate cognitive challenge.

30 Minutes

For intermediate to advanced users. Provides ample training volume, though longer sessions don't proportionally increase benefits.

Beyond 30 Minutes

Not recommended. Cognitive fatigue decreases efficiency, and increased errors may reduce training effectiveness.

The Law of Diminishing Returns

Doubling your training time doesn't double the benefits. Sessions beyond 30 minutes have been reported to show decreased effectiveness due to reduced concentration from fatigue. "Training for the right duration consistently" matters more than "training longer."

Weekly Frequency: How Often for Best Results?

Recommended Frequency: 4-5 Times Per Week

The most commonly used protocol in research is 5 times per week (every weekday).

Effects by Frequency

Weekly Frequency	Effect	Characteristics
Once per week	△ Limited	Difficult to see results. May work for maintenance only
2-3 times/week	○ Effective	For busy people. Results come slower
4-5 times/week	◎ Optimal	Standard in research. Recommended
7 times/week	○ Effective	No rest days increases burnout risk

Research Demonstrating the Importance of Frequency

A working memory training study with older adults (2023) found:

5x per week group: Significant cognitive improvement observed
1x per week group: Limited improvement

This demonstrates that consistent stimulation is necessary for promoting neuroplasticity.

Why Include Rest Days

1
Memory Consolidation
During rest, your brain organizes learned information and consolidates it into long-term memory. This process is particularly active during sleep.
2
Recovery from Cognitive Fatigue
Continuous high-load cognitive tasks accumulate fatigue. Appropriate rest maintains efficient training.
3
Maintaining Motivation
Having rest days reduces the pressure of "having to do it every day," making long-term continuation easier.

Best Time to Train

Morning vs. Evening: When Should You Train?

Morning Training

Pros: Fresh brain, easier to incorporate into daily routine, less affected by other commitments

Cons: Difficult for non-morning people, may not be fully awake immediately after waking

Evening Training

Pros: Utilizes relaxation time after work, sleep shortly after may enhance memory consolidation

Cons: Concentration may decrease due to fatigue, more likely to have conflicting plans

Consistency is Most Important

Research doesn't show a clear advantage for specific times of day. What matters most is training at the same time every day. This makes habit formation easier and improves adherence.

Optimizing Your Training Condition

To maximize training effectiveness:

1-2 hours after meals: Blood sugar is stable, less drowsiness
Moderate caffeine: One cup of coffee can enhance focus (too much is counterproductive)
Quiet environment: Minimize external distractions
Phone away: Notification interruptions significantly impair concentration

Specific Training Schedules

For Beginners: First 4 Weeks

1
Week 1: Familiarization Period
Duration: 10-15 minutes/day Frequency: 5x per week (weekdays) Level: Start at N=2
Goal: Get comfortable with the rules and controls. Don't worry about scores.
2
Week 2: Serious Start
Duration: 15-20 minutes/day Frequency: 5x per week Level: Move to N=3 when achieving 80%+ at N=2
Goal: Focus on rehearsal strategies.
3
Weeks 3-4: Establishment Period
Duration: 20-25 minutes/day Frequency: 5x per week Level: Adaptive adjustment (level up at 80%, down below 70%)
Goal: Establish the habit. Maintain this pace consistently.
4
Week 5 Onwards: Maintenance & Development
Duration: 20-25 minutes/day Frequency: 4-5x per week Level: Progress at your own pace
Goal: Sustainable training integrated into daily life.

For Busy People: Minimum Effective Plan

A realistic plan for those with limited time.

Item	Setting
Daily duration	15 minutes
Weekly frequency	3-4 times
Period	Minimum 6 weeks
Total time	~4.5-6 hours

Even Minimum Training Works

Research confirms effects even with shorter training protocols. "Some training" is definitely better than "no training." Don't aim for perfection—choose a plan you can maintain.

Intensive Plan: For Quick Results

For those with specific goals (before exams, important projects, etc.).

Item	Setting
Daily duration	25-30 minutes
Weekly frequency	6 times
Period	2-3 weeks
Total time	~5-7.5 hours

This plan aims for short-term results. Transition to a regular plan afterward to maintain benefits.

Long-Term Schedule Design

3-Month Program

1
Month 1: Foundation Building
5x per week, 20 minutes daily to establish the habit. Goal: Handle N=2-3 consistently.
2
Month 2: Intensification
5x per week, increase to 25 minutes daily. Challenge N=3-4 and actively train working memory.
3
Month 3: Stabilization & Development
4-5x per week, maintain 20-25 minutes daily. Progress at your own pace.

Maintenance Plan

For long-term continuation beyond 3 months:

Maintenance Mode

2-3x per week, 15-20 minutes per day. Minimum training to maintain effects. Useful during busy periods.

Booster Periods

Every 3-6 months, return to 5x per week, 25 minutes daily for 2-3 weeks. Helps reactivate benefits.

Keys to Successful Training Plans

Tips for Building Habits

Set Triggers

Link to existing habits like "after morning coffee" or "when I get on the commuter train."

Keep Records

Even just checking off a calendar is effective. Maintaining your streak becomes motivation.

Don't Aim for Perfect

Missing one day is fine as long as you don't miss two in a row. Continuation is what matters most.

Prepare Your Environment

Designate a specific place and time for training. Reducing preparation friction makes it easier to continue.

Flexible Adjustments

Some days won't go as planned. When that happens:

Short on time: Do even 10 minutes (maintains the habit)
Feeling tired: Lower the level by one
Completely missed a day: Don't do double the next day—just resume normally

Flexibility is the Key to Continuity

Rules that are too strict cause people to quit. Approach it with the mindset that "80% compliance is good enough."

Frequently Asked Questions (FAQ)

Q: How many minutes per day should I do Dual N-Back training?

Research suggests 20-25 minutes per day is optimal. While 15 minutes can provide benefits, effects become more stable at 20+ minutes. Training beyond 30 minutes may reduce efficiency due to cognitive fatigue.

Q: How many times per week should I train for effective results?

4-5 times per week is most effective. Research protocols typically use 5 days per week (weekdays). Training 3 times weekly can still produce results, but once per week shows limited effects.

Q: Is training every day better than 5 times per week?

5 times per week (weekends off) is recommended. Rest days allow your brain to integrate information and consolidate memories. Daily training without breaks increases the risk of burnout and decreased motivation.

Q: Is morning or evening better for training?

Individual differences exist, but mornings generally offer a fresher brain state. However, consistency is most important. Training at the same time each day helps establish a sustainable habit.

Q: What schedule should beginners start with?

Start with 10-15 minutes per day, 5 times per week for the first 1-2 weeks. Gradually increase to 20-25 minutes as you become comfortable. Starting with too much too soon often leads to giving up.

Summary: Three Key Numbers for Effective Training

Numbers to remember for maximizing Dual N-Back benefits:

Item	Recommended Value
Daily duration	20-25 minutes
Weekly frequency	4-5 times
