Development of neural processes underlying integration of phonological and orthographic information were assessed by measuring event‐related brain potentials (ERPs), judgment accuracies and reaction times (RTs) in 20 children (9–10 years) and 20 adults performing visual rhyme judgments. Half the trials were phonologically and orthographically congruent across the prime‐target pairs (e.g., thrown–own, cake–own), and half were incongruent (e.g., gown–own, cone–own). For both children and adults, behavioral performance was most affected when different phonological representations had to be encoded from similar orthographic representations (e.g., gown–own), and the amplitudes of the N350 reflected effects of both rhyme and phonological/orthographic congruency. Latencies of the N350 were shorter over the left hemisphere only in adults, and phonological/orthographic incongruence produced greater delays in children's processing. Therefore, it appears that neural systems mediating rhyming judgments develop early; however, adults exhibit increased efficiency for left‐hemisphere processing and are less affected by interference from incongruent phonological and orthographic codes. © 2003 Wiley Periodicals, Inc.
