Table 2 Reaction times (in milliseconds) for all conditions in the double-pedal experiment (Experiment 2b) with the difference between single- and dual-task conditions expressed by dual-task costs (DTcost)
From: The impact of predictability on dual-task performance and implications for resource-sharing accounts
