Linear Mixed-effects Model of the Effect of Accuracy on Response Amplitude

Fixed Effects	Estimate	SE	df	t	p
Baseline	105.2	36.1	4.2	2.9	.04
Incorrect responses × Posterior location	−25.6	10.2	65.8	−2.5	.01
Incorrect responses	11.3	6.6	66.1	1.7	.09
Posterior location	19.6	21.8	22.8	0.9	.38

Results of an LME model on the relationship between response amplitude and behavioral accuracy for auditory noise, visual noisy audiovisual speech (AnVn stimulus condition). The fixed effects were the location of each electrode (Anterior vs. Posterior) and the behavioral accuracy of the participant’s responses (Correct vs. Incorrect). Participants, electrodes nested in participants, and stimulus exemplar were included in the model as random factors. The baseline for the model was the response in anterior electrodes for correct behavioral responses. Baseline is shown first; all other effects are ranked by absolute t value. Significant effects are shown in bold.
