From: The impact of predictability on dual-task performance and implications for resource-sharing accounts
Performance on the 6 predictability conditions. a Tracking performance in Experiment 1 as indicated by root-mean-square error (RMSE). The light gray line represents mean RMSE for dual-task conditions, the dark gray line single-task conditions. Asterisks denote significant differences between single- and dual-task conditions. Dual-task costs, which are added to the graph as percentages, were significantly reduced in the 200-ms and 400-ms conditions. b Reaction times in dual-task conditions. Asterisks denote significant differences between predictability conditions. Conditions varied in predictability (i.e., length of the visible path) from 0 to 800Â ms. In both panels, error bars show the standard error
