Notes. N=78. df = 76. Correlations greater than r = .22 are significant at α = .05, correlations greater than r = .29 are significant at α = .01; DAPPFR = Direct Artificial Personal Probability Factor Rotation; Salient factor loadings shown in boldface. Correlation between Gc and Gf factors r = .66.

r_xx =Test-retest alternate form reliability based on first and second administrations (with counterbalanced forms).

Because of content overlap, the PS tests were not included with the cognitive tests in the factor analysis.
