Findings support the psychological reality of sentence embedding processes in ASL, further supporting the claim that visually based languages achieve the same functional goals as speech, although with different means.

Comments on several quantitative approaches to semantic knowledge representations (the focus of this special issue). Points out some of the ways in which Latent Semantic Analysis and Hyperspace Analog to Language fall short of being plausible theories about psychological reality. Examines in-principle failures and wrong-kind failures that arise in…

Reports on the results of four experiments that show that people can recognize ironic meanings that were not intended, and that processing unintended irony can be done easily precisely because speakers' utterances, unbeknownst to them, create ironic situations.
