Results of the confirmatory factor analysis testing the proposed two factor model: ability (reaction time variability and d′) and strategy (mean reaction time and criterion). We considered a ratio of χ2 to degrees of freedom = ≤3, SRMR and RMSEA values = ≤.06, and CFI and TLI values > .95 to be indicators of good model fit (Hu & Bentler, 1999; Schreiber et al., 2006). All criteria indicated a good fit except for Root Mean Square Error of Approximation (indicated by * in the table).

Quality of Fit Measurement Value
χ2/degrees of freedom 2.525*
Standardized Root-Mean-Square Residual (SRMR) 0.024*
Root Mean Square Error of Approximation (RMSEA) 0.104
Comparative Fit Index (CFI) 0.994*
Tucker-Lewis Index (TLI) 0.963*
