The authors' claim that analogical reasoning is the product of relational priming is compatible with language processing work that emphasizes the role of low-level automatic processes in the alignment of situation models in dialogue. However, their model ignores recent behavioral evidence demonstrating a effect on relational priming. We discuss implications of these data.
I argue that alignment of linguistic representations and situation models in dialogue are qualitatively distinct. By virtue of the isomorphy between interlocutors' linguistic representations, interlocutors align their linguistic representations fully. However, evidence about situation models is indirect and mediated through language, with the result that alignment of situation models is only partial.
Levelt, Roelofs, & Meyer (henceforth Levelt et al. 1999) propose a model of production incorporating a lemma stratum, which is concerned with the syntactic characteristics of lexical entries. We suggest that syntactic priming experiments provide evidence about how such syntactic information is represented, and that this evidence can be used to extend Levelt et al.'s model. Evidence from syntactic priming experiments also supports Levelt et al.'s conjecture that the lemma stratum is shared between the production and comprehension systems.
