Fig. S1.

Apparent auditory lateralisation and frequency of experimental stimuli. The words ‘YES’ and ‘NO’ were presented at apparent spatial orientations of − 90° and ± 90° respectively, and each occurred approximately 15% of the time within an experimental block. One of the two words was randomly designated as the explicit target for the block, while the other served as the implicit target. Randomly selected distractor words from the list in Inline Supplementary Table S1 were presented equally randomly at one of seven spatial orientations from − 68° to + 68°, with each orientation being selected approximately 10% of time in a block.
