Researchers have long sought to determine the strength of the relation between prosody and the interpretation of scopally ambiguous sentences in English involving quantification and negation (e.g. All the men didn't go). While Jackendoff (1972) proposed a one-to-one mapping between sentence-final contour and the scope of negation (falling contour: narrow scope, fall-rise contour: wide scope), in subsequent work, researchers (e.g. Ladd 1980; Ward & Hirschberg 1985; Kadmon & Roberts 1986) disentangled the link between prosody and scope. Even though these pragmatic accounts predict variability in production, they still allow for some correlation between scope and prosody. To date, we lack systematic evidence to bear on this discussion. Here, we present findings from two perception experiments aimed at investigating whether prosodic information – including, but not limited to, sentence-final contour – can successfully disambiguate such sentences. We show that when speakers provide consistent auditory cues to sentential interpretation, hearers can successfully recruit these cues to arrive at the correct interpretation as intended by the speaker. In light of these results, we argue that psycholinguistic studies (including language acquisition studies) investigating participants’ ability to access multiple interpretations of scopally ambiguous sentences – quantificational and otherwise – should carefully control for prosody.
