Fig 5. Characteristics of Model ♯2.

This model included 4 factors: Tension, Abstractness, the “Visual/Verbal” dimension of the Learning Style and Self-Reliance. Abstractness, the “Visual/Verbal” dimension of the Learning Style and Self-Reliance had positive weights. Tension was the only factor to have a negative weight. This model enabled to explain 80.9% of MI-BCI performance variance [$R_{adj}^2$ = 0.809, p < 0.001].
