to the emotional and objective icons. For only the emotional icons,
the congruence score was more strongly correlated with the 2D distance
(-0.67) and the valence distance (-0.69), but was not correlated
with the arousal distance (-0.11). For the objective icons, the
2D distance and the valence distance were strongly correlated with
the congruence score (-0.72 and -0.79). Interestingly, the arousal
distance was also moderately correlated (-0.40).
