  1. This table reports the results of our main statistical analysis. The total n of analysed missions was 194. Unstandardized coefficients explain how much the NASA-TLX value increases for one step on the scale of the variable that is shown in the first row. (F (7;79) = 15,018; p < 0.01; adjusted R2 = 53%; SE = 13%)
