Note. AIC = Akaike information criteria. BIC = Bayesian information criteria. RMSEA = Root Mean Square Error of Approximation. CFI = Comparative Fit Index. SRMR = Standardized Root Mean Square Residual. EM = episodic memory. SM = semantic memory. Con = configural. Met = metric. Scal = scalar. PScal = partial scalar.

First indicator intercepts constrained for this and all consequent models.
