Comparison of correlations between Ratio_−RT and RT-difference scores on PSLT, and fluid abilities measures and age.

Fluid abilities measures	Pearson correlation with RT-difference scores	Pearson correlation with Ratio−RT	p-value
RAPM	0.03	0.29	0.011
Dot matrix	0.05	0.41	< 0.001
Inspection time	0.06	−0.25	0.002
Symbol digit	−0.16	0.19	0.001
Mental rotation	0.04	0.48	< 0.001
Age	0.33	−0.08	< 0.001

RAPM, Ravens Advanced Progressive Matrices (number of correct items); Dot matrix, Dot Matrix Task (number of correct items completed); Inspection time, averaged z-score from two Inspection Time tasks; Symbol digit, Symbol-Digit Coding Task (number of correct items completed); Mental rotation, Mental Rotation Task (number of correct items). p-value, significance value for a William's (1959) test comparing the two correlations between each fluid ability and the two sequence learning measures. Smaller Inspection Time scores indicate faster processing speed; hence, the negative correlation between Inspection Time and Ratio_−RT suggests a positive relationship between processing speed and learning.
