Despite evidence that learners are storing a lot more than simple words, it is still unclear what determines whether a phrase is stored holistically. For example, storage could be driven by either phrasal frequency or by the mutual predictability of a phrase's component parts . Further, the processing consequences of holistic storage are also unclear. Given that sentence processing is incremental, how does recognition of individual words give rise to recognition of holistically stored phrases? The present study examines these questions. Specifically, participants are presented with sentences that contain compound nouns in locally plausible or locally implausible contexts. We examine whether participants are able to overcome local implausibility effects more easily if the compound nouns are highly predictable. We find that predictability does not overcome local implausibility effects, suggesting that either predictability is not driving holistic storage or that holistic storage driven by predictability does not facilitate comprehension in our task.
