We present data from three experiments using a sequential binary choice task that explore the relationship between two
proposed cognitive control functions: set-shifting and place-keeping (i.e., keeping track of one’s place within a
sequential task). The task involves switching from one stimulus-response mapping to another across trials, according
to a predefined sequence and in the face of occasional brief interruptions. Response-stimulus interval, interruption
length and interrupting task were varied. In each study, response time, sequential error type and interruption accuracy were recorded.
