Table 4. Summary of the fixed and random effects in the multi-level model in Experiment 2a.

Accuracy
	Fixed Effects	Coefficient	SE	z	Pr(>|z|)
	Intercept	2.61753	0.2105	12.435	<0.001
	Condition	−0.62162	0.10156	−6.121	<0.001
	Stimulation	−0.65049	0.26747	−2.432	0.015
	Condition*Stimulation	−0.04824	0.12042	−0.401	0.689
	Random Effects	Variance
	Subject intercept	0.35317

Stimulation has two levels (cathodal and sham), and Condition has two levels (C and I). See text for details. * signifies an interaction.
