Dual N-Back training

Personal project to build a JS Dual N-Back training app

What is dual n-back training?

For my purposes it’s a tool for exercising & training my working memory, but I couldn’t say for sure if it’s had any benefit yet. However, making this app in JavaScript has been a useful exercise!

Instructions

You will be shown a series of coloured squares. Each time the square changes you will be mentally comparing it with the square 2 steps back to determine if the colour or position (or both) match.

Press the Q key to report a colour match and E for a position match.

For example:

• Round 1: Red square, top left - no previous round to compare
• Round 2: Blue square, top right - no previous round to compare
• Round 3: Red square, top right - compare with round 1: colour match
• Round 4: Red square, top right - compare with round 2: position match
• Round 5: Yellow square, bottom right - compare with round 3: no match
• Round 6: Red square, top right - compare with round 4: colour & position match

Scoring

Each correctly reported match scores 1 point. Each incorrectly reported match or unreported match loses 1 point.

After 20 rounds your score will display along with the possible score.
