(A) Mean triplet learning index across experimental blocks for the control and the dyslexia group. Boxes indicate the inter-quartile range (around the median line), and single data points correspond to individual participants. (B) Triplet learning index (y-axis) as a function of the number of presented triplets (x-axis) throughout the first experimental block for the control and the dyslexia group. Dashed lines correspond to the actual data, and bold solid lines are logarithmic functions (y = a * log(x) + b) fitted to the data. Shaded areas indicate ±1 standard error of means (in the actual data). The gray horizontal bar indicates the time window in which the TLI differed significantly between the control and the dyslexia group, as tested using a cluster-based permutation approach.
