Abstract One cross-linguistically recurrent asymmetry between affirmation and negation is the neutralization of tense-aspect distinctions in negatives. A functional explanation proposed for this is that in their typical discourse context negatives have less need for temporal specification than affirmatives and in some languages this discourse preference is reflected as fewer tense-aspect distinctions in grammar. To examine whether such a discourse preference exists, we compare the use of temporal adverbials in affirmatives and negatives in English, Finnish and Korean corpus data. The results provide qualified support for the hypothesized discourse preference: in English and Korean, affirmatives are likelier to have temporal adverbials than negatives, but Finnish shows no statistically significant difference. In English and Finnish, affirmatives are likelier than negatives to contain adjuncts indicating temporal position. Verb semantics is found to interact with temporal specifications. The study also uncovers further differences between affirmatives and negatives in the use of adverbials.
