What we know about knowing: Presuppositions generated by factive verbs influence downstream neural processing.

Presuppositions convey information that comprehenders assume to be true, even when it is tangential to the communicator's main message. For example, a class of verbs called 'factives' (e.g.

Linguistic inability or poor performance: Dissociating scalar implicature generation and mismatch in the developing brain.

Behavioral investigations of the acquisition of some have shown that children favor its logical interpretation (some and possibly all). Adults, however, use the pragmatic interpretation (some but not all) derived by a scalar implicature. Certain experimental manipulations increase children's rates of adult-like responses, indicating that children are capable of computing implicatures.

When three is not some: on the pragmatics of numerals.

Both numerals and quantifiers (like some) have more than one possible interpretation (i.e., weak and strong interpretations).

When some is not every: dissociating scalar implicature generation and mismatch.

Making inferences beyond the literal meaning of sentences occurs with certain scalar expressions via scalar implicatures. For example, adults usually interpret some as some but not all. On the basis of behavioral research, it has been suggested that processing implicatures is cognitively costly.

On the role of entailment patterns and scalar implicatures in the processing of numerals.

There has been much debate, in both the linguistics and the psycholinguistics literature, concerning numbers and the interpretation of number denoting determiners ('numerals'). Such debate concerns, in particular, the nature and distribution of upper-bounded ('at-least') interpretations vs. lower-bounded ('exact') construals.

Noun-verb dissociation in aphasia: the role of imageability and functional locus of the lesion.

Aphasic patients occasionally manifest a dissociated naming ability between objects and actions: this phenomenon has been interpreted as evidence of a separate organization for nouns and verbs in the mental lexicon. Nevertheless Bird et al. [Bird, H.
