Figure 1

Example stimulus display. Subjects fixated on the central cross while attending to either the red or green items. The side containing the attended color varied unpredictably across trials. The task was to report whether the letter located in the middle of the attended-color array (the target) was a vowel or a consonant. Experiment 1 included three target-flanker distances: 16.8°, 3.13°, and 1.48°. Experiment 2 included no-distractor trials and five target-flanker distances: 16.8°, 4.12°, 3.13°, 2.14°, and 1.48°. Conditions included in both experiments are indicated with a * symbol.
