Estimates represent unstandardized coefficients from robust linear mixed models with Participant included as a random intercept. Predictors whose 95% confidence intervals do not contain 0 are interpreted as statistically significant. For the categorical predictors Biased Block and Directionality Bias, the first of the two biased blocks and the rightward directionality bias served as reference levels, respectively.
