Fig. 2: Behavioral performance modulated by training.
From: Dynamic reconfiguration of functional brain networks during working memory training
a, b Line plots representing mean behavioral performance measured as \(d^{\prime}\),calculated for all training phases (Naive, Early, Middle, and Late), dual n-back conditions (1-back and 2-back), and groups (a experimental, n = 21, and b control, n = 21). We found a significant interaction effect between the session, condition, and group. After training, the experimental group exhibited no difference in behavioral performance between the 1-back and 2-back conditions. Dots represent mean values; error bars represent 95% confidence intervals. c No significant difference between groups was found for \(d^{\prime}\) reduction (from Naive to Late sessions) during the 1-back task condition. d The experimental group showed a significant reduction in \(d^{\prime}\) compared with the control group during the challenging 2-back condition (two-sample t test, two-sided; p = 0.004). Boxes represent the interquartile range (IR) between 25th and 75th percentiles. The thick line in the center of each box represents the median. The upper and lower error bars display the largest and smallest values within 1.5 times IR above 75th percentile and below 25th percentile, respectively. ***p < 0.001 Bonferroni-corrected; **p < 0.05 Bonferroni-corrected.
