A) In Experiment 1, stimuli were presented individually either in the right or left visual field during passive viewing. SF = spatial frequency. B) In Experiment 2, stimuli were presented centrally and participants determined if the letter H or S was present, regardless of whether it appeared at the global or local level. Irrelevant distracter letters (E or A) were presented at the other level.
