Lexical and sublexical translation of spelling to sound: Strategic anticipation of lexical status.

Two experiments on oral reading of single words compared naming performance in pure blocks of nonwords or exception words with performance in blocks of randomly mixed nonwords and exception words. Ss named exception words faster and made fewer regularization errors when they were not also prepared for nonwords. These data suggest Ss inhibit or ignore the computation of assembled phonology when only exception words are expected. Ss named nonwords faster, but no more accurately, when low-frequency exception words were not also anticipated. Thus, Ss' readiness to execute assembled phonology appears to be adjusted in relation to the likely time course of retrieval of learned pronunciations, when the latter must be attended to
