Correlations between elicited imitation memory performance and ERP familiarity response (familiar-unfamiliar) at the end of the 9-month intervention (n = 24).

	Recall of Individual Items	Recall of Ordered Pairs
Nc Adaptive Mean Amplitude
Prefrontal	−0.439*	−0.373†
Right frontal	−0.417*	−0.411*
Left frontal	−0.140	0.001
Central	−0.319	−0.339
Nc Latency to Peak Amplitude
Prefrontal	0.005	0.191
Right frontal	0.043	0.105
Left frontal	−0.394†	−0.371†
Central	−0.294	−0.299
PSW (area under the curve)
Prefrontal	−0.625**	−0.609**
Right frontal	−0.032	−0.094
Left frontal	−0.453*	−0.134
Central	−0.455*	−0.290

Elicited imitation memory performance is standardized for age. Interpretation of a negative correlation means that better delayed recall is associated with a greater Nc amplitude for familiar stimuli (compared to unfamiliar), a shorter Nc latency to familiar stimuli (compared to unfamiliar), and a greater PSW response to unfamiliar stimuli (compared to familiar).
