Table 1.
Demographic data (means, standard deviations, and proportions) for all age groups.

Average RTs and general skill learning across the lifespan.
Average RTs refer to the RTs of all correct responses averaged over the entire task (A). General skill learning refers to the RT changes occurring during the time course of the task (B), which can be quantified as the RT difference between Epoch 1 and Epoch 4 (C). Group averages are presented in panel A-C, and individual data separately for each age group are presented in panel D-E. Error bars indicate standard error of mean (SEM).
Fig 2.
General skill learning ratio scores across the lifespan.
The ratio scores for group averages (A) and individual data (B) are presented. The ratio score can be interpreted as a percentage change in performance (e.g., the 7-8-old age group exhibited an approximately 23% speed-up from Epoch 1 to Epoch 4 relative to their average speed during task). Error bars indicate standard error of mean (SEM).

Relationship between average RTs and indices of general skill (raw RT difference and ratio scores) and triplet learning for each age group.
Table 3.
Minimum and maximum values, mean, standard deviation (SD) and percentiles of average RTs and general skill learning for each age group.
Fig 3.
Average RTs (A) and general skill learning (B-D) across the lifespan for a subsample of the participants to control for age-related average RT differences.
Only those participants are included in this subsample whose average RTs are between 400 and 550 ms. For details on the measures presented here see the legend of Fig 1. Error bars indicate standard error of mean (SEM).
Fig 4.
Statistical learning across age groups.
Triplet learning score was quantified as an RT difference for low- and high-frequency triplets, averaged across the entire task. Larger values represent better learning performance. Error bars indicate standard error of mean (SEM).
