In a commentary on this model, which we called the extended sensory/functional theory (ESFT; Sha- piro & Caramazza, 2001), we argued that the assumptions upon which it is based are not empirically credible and that even if they were, the model would not be adequate to account for all cases of putative grammatical category-specific deficits. The proponents of the ESFT have now responded to our criticism by defending the core assumptions of the model and by questioning our explanation of cases we judged to be problematic for it (Bird, Howard, & Franklin, 2001). In our view, their response is flawed in two crucial respects. First, some of the empirical claims made in defense of the ESFT are either misleading or plainly inaccurate. Second, and more importantly, we believe that the strictures that Bird and colleagues would impose on the collection and interpretation of data have the practical effect of redefining the topic of inquiry to avoid the question that is of greatest interest—namely, how spoken language is produced. We will first deal briefly with the inaccuracies in Bird and colleagues’ response, after which we will return to the broader theoretical issue at stake. To begin with, the arguments that Bird and colleagues make in defense of the sensory/functional theory, on which the ESFT is based, are substantially irrelevant. First they assert that even ‘‘small’’ differences in the ratios of sensory to nonsensory features attributed by normal subjects to living and nonliving things are ‘‘worth not- ing.’’ We contend that even if these differences were statistically reliable, they would not be ‘‘worth noting’’ because they are not large enough to support the kinds of apparently categorical distinctions that they are supposed to underlie. 1 In other words, The writing of this article was supported in part by NIH/NIDCD Grant DC04542.
