Summary of the generalized linear model (GLM) analysis with values from the final model.

Behavior	Right	Left	Time	Right:Left	Right:Time	Left:Time	Right:Left:Time
LD	0.049 (0.05)	−0.036	0.02	0.008	0.0065	0.042	0.053 (0.02)
HE	−0.005	0.088 (<0.001)	0.11 (<0.001)	0.027	0.017	−0.002	0.014
Steering	0.013	0.055 (0.03)	0.094 (<0.001)	0.027	0.009	0.0373	0.044
RT	0.01	0.09 (<0.001)	0.07 (<0.01)	0.017	−0.02	0.05	0.009

Each row shows the model results for three driving behaviors: lane deviation (LD), heading error (HE), and integrated steering response (Steering). Each column shows model coefficients and their respective p-values in parentheses for the terms in the final model, including alpha power in two parietal clusters (Right and Left) as well as a time on task term (Time). Columns with colons indicate interaction terms. Significant effects retained in the final model are in italicized bold. Terms not included in the final model appear in regular text.
