Table 4.
The likelihood ratios and results of a likelihood ratio test for all models in Experiment 3. The Best Model is the model that is compared against all Comparison models that differ by removing a factor. The Likelihood reports how much more likely the best model is to the comparison. The chi-square statistic results report whether the best model performed statistically better than the comparison.
