Linear mixed effect model results for general MdRQA with trial type, language experience, and tempo range as predictors of %REC, �T, and MAXL.

Each MdRQA metric was predicted using a separate model. Marginal and conditional R2 for each model included below each model label. Effect sizes provided as standardized estimates (ß) for statistically significant predictors. As noted in the Model Specifications section, the use of deviation coding yields k-1 variables that test the difference between a given level of the categorical variable and the reference level. General MdRQA models used the incomplete trials, monolingual language experience, and middle tempi as reference categories; for more on mathematical interpretation of deviation-coded interaction terms, see Barr et al. (2013) [51].
