AB It is often assumed that word reading proceeds automatically. Here, we tested this assumption by recording event-related potentials during a psychological refractory period (PRP)paradigm, requiring lexical decisions about written words. Specifically, we selected wordsdiffering in their orthographic neighborhood size–the number of words that can be obtainedfrom a target by exchanging a single letter–and investigated how influences of this variabledepend on the availability of central attention. As expected, when attentional resources forlexical decisions were unconstrained, words with many orthographic neighbors elicitedlarger N400 amplitudes than those with few neighbors. However, under conditions of hightemporal overlap with a high priority primary task, the N400 effect was not statistically different from zero. This finding indicates strong attentional influences on processes sensitive toorthographic neighbors during word reading, providing novel evidence against the full automaticity of processes involved in word reading. Furthermore, in conjunction with the observation of an underadditive interaction between stimulus onset asynchrony (SOA) andorthographic neighborhood size in lexical decision performance, commonly taken to indicateautomaticity, our results raise issues concerning the standard logic of cognitive slack in thePRP paradigm
