Impact of different motivational levels for sucrose on the punishment sensitivity. Upper left panel: box and whisker plot showing an increase in the BPs at the group level (Wilcoxon signed-rank test, p < 0.001). Upper right panel: box and whisker plot showing no significant change in the AUCs at the group level (Wilcoxon signed-rank test, p = 0.06). Middle left panel: box and whisker plot showing an increase in the BPs in a subgroup in response to increased sucrose value (Wilcoxon signed-rank test, p < 0.001). Middle right panel: bar graph showing no significant change in the AUCs within the BP-increasing subgroup (paired t test, p = 0.12). Lower left panel: box and whisker plot showing a decrease in the BPs in a subgroup in response to increased sucrose value (Wilcoxon signed-rank test, p < 0.01). Lower right panel: bar graph showing no significant change in the AUCs within the BP-decreasing subgroup (paired t test, p = 0.18). Data are represented as mean ± SEM in the bar graph. The box extends from 25^th to 75^th percentile. The upper whisker represents the largest value smaller than the sum of the 75^th percentile and 1.5 times the inter-quartile distance or the maximum of the data if the maximum is smaller than the sum. The lower whisker represents the smallest value greater than the difference between the 25^th percentile and 1.5 times the inter-quartile distance or the minimum of the data if the minimum greater than the difference. The filled circles represent data beyond the whiskers.
