Changes in Model Fit After Dropping Individual Paths via the Path-Dropping Process for the ART, Reading, and Intelligence Model (Shown in online Figure S2)

Path set	Change in fit after dropping paths
	ΔAIC	Cumulative no. paths dropped (Δdf)	p
Within-trait paths	0	0	1
Cross-lagged paths	−5.05	5	.42
Covariance paths	−6.20	7	.35

Note. The saturated model included 15 paths; the final model included 8.

AIC = Akaike information criterion. Reference model AIC = 507.11 on 7 df.
