Capacity Level 3
How to play the Capacity, Level 3 Game
This is the Episodic N-Back Game, and is a more complex extension of the classic dual N-back game.
First ensure that you know how to play the dual n-back game (Level 2).
In the Episodic n-back you are required to integrate information from the visual and audio modes and this trains your working memory and attention systems in a way that standard dual n-back games do not. This helps you train your memory for personal experiences (known as episodic memory).
In the Level 3 Game, each block alternates randomly between:
- Standard Dual N-back (Level 2) – labelled ‘OR’
- XOR Dual N-Back – looking for matches in either modality alone, but not when they occur together
- AND Dual N-Back – looking for matches when they occur together but not when they occur alone
XOR Dual N-Back Game
Unlike the standard dual n-back in Level 2, the XOR mode requires you to use your attention control to suppress a ‘match’ response when both modes occur together.
Here is an example stimuli for n-back = 2 in XOR mode:
AND Dual N-Back Game
In AND dual n-back mode, the challenge is to respond when there is an audio and visual match at the same time, but not when there is an audio and visual match on its own.
AND and XOR n-back modes require opposite responses to each other. The AND mode requires you to use your attention control to suppress a ‘match’ response when there are audio or visual matches that occur alone.
