Event-related potentials (ERPs) were recorded from one midline and three pairs of lateral electrodes while subjects determined whether a pair of sequentially presented pictures had rhyming or nonrhyming names. During the 1.56-sec interval between the two pictures, the slow ERP wave recorded over the left hemisphere was more negative-going than that over the right, especially at frontal electrodes. The ERPs evoked by the second picture differed as a function of whether its name rhymed with its predecessor. This difference, taking the form of increased negativity in ERPs to nonrhyming items, had an earlier onset and a greater magnitude at right than at left hemisphere electrodes. This pattern of ERP asymmetries is qualitatively similar to that found when words are rhymematched. It is therefore concluded that such asymmetries do not depend on the employment of orthographic material and may reflect some aspect(s) of the phonological processing of visually presented material. @ 1990 Academic Press.
