Schematic of stimulus presentation and timing within one experimental run. No-Ad: No-adaptation; Ad-C: Adaptation-congruent; Ad-I: Adaptation-incongruent; Tar: epoch including a target. Note that across adaptation conditions, each letter and each speech sound exemplar was equally often presented in congruent and incongruent audiovisual combinations. Subjects did not know when targets would appear; the purpose of the task was to obtain equal attention levels for the different conditions.
