Table 3

Coefficients for fixed effects in the mixed effects linear regression of log (completion time) on task type and sensor RMS, where participants were included as a random effect. p-values for main effects include removal of any interaction terms. Estimate for participants is the random effect parameter. indicates that fields marked with an asterisk are for covariates that interact with other variables.
