Point Estimates and 95% Credible Intervals of the Fixed Effects in Experiment 1 and 2.

Note. Per experiment, the parameter estimates of the fixed effects of four models are reported. Model (1) comprised only the main effect of word type (and of inversion in Experiment 2). Model (2) tested the main effect of word frequency (and inversion in Experiment 2). Model (3) is an expansion of Model (2) in that the main effects of pixel density, trial number, age of acquisition and concreteness were added. Finally, model (4) only consists of the main effects of pixel density and trial number. Models (1) and (4) were fitted using all data, model (2) was run on the word data only and model (3) included all words except one because concreteness and age of acquisition estimates were not available for this stimulus. To facilitate the comparison, all continuous variables were z-transformed (see Table 1 for means and standard deviations of the variables).
