The influence of phonology on visual word perception tasks is often indexed by the presence or absence of consistency effects. Consistency concerns whether there exists more than one way to pronounce a spelling body (e.g.,_INT as in HINT and PINT versus_EAP as in HEAP and LEAP). The present study considers a similar factor. Feedback consistency concerns whether there is more than one way to spell a pronunciation body (e.g., /_ip/ as in HEAP and DEEP versus /_Ob/ as in PROBE and GLOBE). Two experiments demonstrate a robust feedback consistency effect in visual lexical decision. Words with phonologic bodies that can be spelled more than one way (e.g.,_EAP as in HEAP) produce slower correct "yes" responses than words with phonologic bodies that can be spelled only one way (e.g.,_OBE as in PROBE). This result constitutes strong support for feedback, top-down models of performance in word perception tasks. Furthermore, the data suggest that previous tests of consistency effects may be misleading because they did not take into account feedback consistency.
