This chapter discusses a series of experiments in which a pre‐cue signals which of several dimensions of an upcoming stimulus is relevant on a particular trial. The event‐related optical signal is used to follow the time course of activity in different cortical areas after the pre‐cue. The data show two types of preparatory brain activities: (1) a domain‐general set, involving first the left middle frontal gyrus and then the lateral parietal cortex; and (2) a domain‐specific set, involving secondary sensory and motor areas of the brain. These data suggest that task preparation involves the operation of a hierarchical, top‐down system.
