a Average normalized response time (RT) for both task variants. b Average normalized accuracy for both task variants. For a and b, shaded regions represent standard errors of the mean. c Average learning magnitude for performance speed per age group. Shaded regions represent the kernel density estimate of the data, colored circles depict individual data, open circles represent group medians, and the horizontal lines depict group means65. CH children, AD adolescents, YA young adults, OA older adults. *p < 0.05 for pairwise group comparisons. d Learning magnitude as a function of age. Quadratic fit from childhood into young adulthood: Learning magnitude = (-0.0008572*age2) + (0.04021*age) + (−0.2226). Quadratic fit for older adults: Learning magnitude = (0.00157*age2) + (−0.1996*age) + 6.4675. n = 33, 33, 32 and 32 for groups of children, adolescents, young adults, and older adults, respectively.
