The effectiveness of nonword orthographic rime primes as a function of
the regularity (as defined by grapheme-phoneme correspondence [GPC] r
ules) of typical pronunciation was examined in this research. In Exper
iments 1 and 2, predictions from GPC and orthographic rime unit accoun
ts converged, but in Experiments 3 and 4 they diverged. Experiment 1 s
howed that when nonword orthographic rimes were used to prime consiste
nt regular words (e.g., mist) and atypically irregular words (e.g., pi
nt), reliable priming was observed for regular words, but priming of a
typically irregular words occurred only in the 2nd block of trials, af
ter the orthographic rime prime itself had been primed by the Block 1
presentation of the target word. In subsequent experiments, only the 1
st block of trials was examined. Experiment 2 replicated the selective
priming of consistent regular words observed in Block 1 of Experiment
1. In Experiment 3, nonword orthographic rimes were as effective at p
riming typically irregular target words (e.g., grind) as they were in
priming inconsistent but typically regular target words (e.g., flint).
Parallel results were observed in Experiment 4, in which nonword orth
ographic rimes were as effective at priming target words with typicall
y irregular orthographic rimes as they were in priming consistent regu
lar target words. The results of these experiments show nonword orthog
raphic rimes are not always phonologically recoded in accordance with
GPC rules.
