Correlations between accuracy-based performance measures (Generation Score, Mean Error Score, and Speed/Accuracy Trade-off) on SRTT and PSLT, and fluid abilities measures and age.

Fluid abilities measures and age	Serial Reaction Time Task (SRTT)		Predictive Sequence Learning Task (PSLT)
	Mean Error Score	Speed/Accuracy Trade-off	Generation Score	Mean Error Score	Speed/Accuracy Trade-off

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); Generation Score, Mean Error Score, and Speed/Accuracy Trade-off, performance measures on the motor sequence learning tasks. A Generation Score cannot be computed for SRTT because participants do not predict the location of the next stimulus as in PSLT. Any absolute r greater than 0.20 is significant at

^*p < 0.05, and greater than 0.27 is significant at

^**p < 0.001.
