Stimuli and design used in Experiment 1. (A) Shape, color, and orientation stimulus sets. (B) Sequence of events in a set of three blocks of trials. A set of three digits was presented at the beginning of each set of three blocks, and participants continuously repeated these digits aloud for the entire set of three blocks. Each block began with a cue indicating which feature set would be used for that block. This was followed with 10 change detection trials with the cued feature set.
