Table 2.
Table showing the results of a maximum likelihood estimated model predicting adults’ performance. Parameter estimates include the mean performance (Mean) in the different conditions, the estimated coefficient (Estimate) of the fixed effects, the Variance of random effects and Chi-square statistics (χ2). Chi-square statistics are associated with pairwise model comparisons with (full model) versus without the effect of interest, where the model without the effect of interest includes all other effects. Planned comparisons test naming effects (test period: pre-naming versus post-naming) in each learning (auditory versus visual) and test (same modality versus cross-modality) condition.
