Quad N-Back imbalance between different stimuli

[Béla Bauchmüller]

Hi everyone,
I recently started training with Quad N-Back, and I’m currently hovering between levels 2 and 3.
What I’ve noticed is that I rarely make mistakes in the position and audio tasks, but my performance on the image and color stimuli is significantly weaker, which drags down my overall score.

Has anyone else experienced this kind of imbalance between the stimulus types?
And if so, do you have any strategies or exercises that helped you even out your performance across all modalities?

Yeah that's common. You should get better at registering each stimulus with practice. You can do dual back with just those stimuli to focus on them.
