Table of curve fit diagnostics for whole brain beta oscillation laterality in development.

Perturbation	Model	R2	adj. R2	AICc
ERD	Linear	0.20	0.19	− 134.2
	Quadratic	0.21	0.21	− 133.2
	Cubic	0.22	0.18	− 131.5
ERS	Linear	0.18	0.17	− 120.2
	Quadratic	0.20	0.18	− 120.6
	Cubic	0.20	0.17	− 118.4

Curve models are of laterality indices of low-beta event-related desynchronization and event-related synchronization as a function of age (n = 78).

Parsimonious model fit based on corrected Akaike’s Information Criterion (AIC_C) is bolded.
