Fig. 8From: The impact of predictability on dual-task performance and implications for resource-sharing accountsReaction time (RT) and root-mean-square error (RMSE) analyses in Experiment 2a (a) and 2b (b). Light gray lines depict dual-task conditions, dark gray lines depict single-task conditions. DT costs are the differences between single- and dual-task conditions, presented as percentages; asterisks denote significant DT costs, **p < .001, *p < .005. Error bars show standard errorsBack to article page
