Figure 4
Correlation of introspective concentration, speed, accuracy, comfort, and discomfort.
Note. Panel (a) depicts the correlation of introspective concentration, speed, and accuracy across all vibration conditions. Panel (b) considers the correlations only based on the data of the conditions with constant and random vibration. The numbers represent the correlation coefficients, blue indicate positive correlations, red negative correlations, and blank cells depict non-significant correlations.

[i] Note. The factor vibration condition includes no-vibration, constant vibration, and random vibration in the ANOVA for introspective concentration, speed, and accuracy. For vibration comfort and discomfort it includes only constant vibration and random vibration.
