Many cognitive tasks have what we refer to as a placekeeping requirement: steps or subtasks must be performed in a linear or other systematic fashion, without repetitions or omissions that would compromise performance. Here we asked whether the cognitive control mechanisms that meet this requirement are specific to individual tasks or general enough to be shared across tasks. Participants (N = 289) performed two tasks (Letterwheel and UNRAVEL) that share a sequential structure but are otherwise distinct. Placekeeping measures correlated significantly across tasks after controlling for construct-irrelevant variance, evidence that individual differences in placekeeping ability correlated across tasks rather than varying independently. Furthermore, an empirical pattern in the form of a crossover interaction in placekeeping error gradients was evident for both tasks, evidence that placekeeping in the two tasks is supported by similar cognitive mechanisms. The results suggest that placekeeping ability is a task-independent cognitive control construct and that placekeeping measures could help predict performance in a range of workplace and everyday tasks.
