The task can either repeat or alternate from one trial to the next.

The colour of a cue indicates whether the participant should judge the parity or magnitude of the digit. Illustration of a cued task switching procedure. The switch cost is the observation that performance is substantially hindered when the task on the current trial (e.g., parity) is different from the task on the previous trial (e.g., magnitude), termed a task alternation (or task switch), relative to when the task is the same, termed a task repetition. For example, a blue or red cue might indicate that participants need to determine whether a target digit is odd or even (parity decision), whereas a yellow or green cue indicates that the participant must determine whether the digit is larger or smaller than five (magnitude decision). For instance, in the cued task switching procedure, participants are presented with a cue (e.g., a coloured rectangle) on each trial, which informs them which of two tasks must be performed. In task switching paradigms, the participant is not asked to implement one task goal, but two (or more), as illustrated in Figure 1 (for a list of key term definitions, see Appendix A). One tool commonly used in the study of our ability to switch between goals are task switching paradigms ( Jersild, 1927 for reviews, see Kiesel et al., 2010 Koch, Poljac, MГјller, & Kiesel, 2018 Monsell, 2003 Vandierendonck, Liefooghe, & Verbruggen, 2010). Understanding how we maintain multiple goals and shift between them, and what costs or benefits might arise from this multitasking, are therefore vital questions that much research has focused on understanding.

While at work, we might repeatedly shift our attention between checking emails, writing a manuscript, and checking on the Java code running in the background. In our everyday interactions with the world, we often balance multiple goals concurrently, flexibly switching between them as needed.
