Orthographic rime priming

Three experiments are described, each using a partial priming technique in which a target word was briefly preceded by a masked trigram. The relative strength of priming effects was assessed by comparing the difference in target word naming times between unprimed and primed trials in different priming conditions. Experiment 1 replicated previous work in demonstrating stronger priming when the target word was primed by the orthographic rime than when the prime constituted otherwise comparable word-final trigrams that do not constitute orthographic rimes. Experiment 2 compared orthographic, phonological rime, and control primes. Only orthographic rime primes reliably increased target word naming speed, although the priming effect was less selective with longer prime durations. In Experiment 3 priming was observed for both orthographic rime and phonological rime primes shown for 150 msec. However, stronger priming was observed with orthographic rime primes. These experiments demonstrate that orthographic rime priming effects do not simply reflect the activation of an intact subunit of the target word articulation program.
