Statistical analysis of differences in behavior.

<p>Statistical analyses of differences in behavior. Linear mixed model with trial, learning phase (phase: acquisition1, acquisition2, retention), the MPP-dose and the learning phase×dose as factors and behavior as dependent variable. Trial, MPP-dose and learning phase×dose interaction as fixed effects. Trial and phase as repeated measures variables with diagonal covariance type. Estimates of fixed effects are given only for the interactions (controls as reference category) and only significant results. Main effects of estimated marginal means. Significant results are indicated in bold (p-values of pairwise comparisons of estimated marginal means are Bonferroni-corrected).
