Eye-voice span was specified as a centered covariate. Therefore, the intercept estimates the Grand Mean SFD. Main effects of covariates (and associated test statistics) are presented in the left four columns; coefficients for their interactions with EVS in the right four columns; see text for details. Bold values indicate significant contrasts.
