Cognitive load effects on β-band network properties in two groups of fast- and slow-performing participants. Both fast- and slow-performing subgroups of participants demonstrate workspace configuration of networks at higher cognitive load, but this task-related effect on efficiency and physical distance is greater in the fast-performing group (high) than in the slow-performing group (low). The dotted lines indicate zero difference in network metrics between different levels of task difficulty. *p < 0.05 and **p < 0.01 for the null hypothesis that task-related change in network metrics is not different between fast- and slow-performing subgroups. Box sizes represent first and third quartile; whiskers show extent of distribution; black dot is the median and blue dots are outliers.
