Stimuli and trial timings. A, Object cues used in the ERP experiment and their target words on nonmatching trials. On matching trials, targets were the names of each object. B, Trial timing in the ERP experiment. Olfactory or visual object cues were followed by written word targets, each with a duration of 1 s with a variable interstimulus interval. C, Object cues used in the fMRI experiment. On matching trials, the object was paired with its name, and on nonmatching trials, the object was paired (one time each) with the names of the other seven objects. D, Trial timing in the fMRI experiment. Olfactory or visual object cues were followed by auditory word targets, each with an approximate duration of 1 s and a fixed 4 s interstimulus interval.
