In recent years proponents of usage-based linguistics have singled out ‘categorization’ as possibly the fundamental cognitive operation underlying the acquisition and use of language. Despite this increasing appeal to the importance of categorization, few researchers have yet offered explicit interpretations of how linguistic categories might be represented in the brain other than vague allusions to prototype theory, especially as implemented in connectionist-like frameworks. In this paper, I discuss in some detail the implications of superimposing the theoretical representations of linguistic structures onto domain-general models of categorization. I first review the evidence that instance-based, or exemplar-based, models of categorization provide empirically and theoretically better models of both domain-general categorization and of linguistic categorization than do the most commonly cited alternative models. I then argue that of the three exemplar-based models currently being applied to linguistic data, Skousen’s Analogical Model (AM) appears to provide the simplest, most straightforward account of the data and that it appears to be fully compatible with our current understanding of the psychological capabilities and operations that underlie categorization behavior.

Over the past 50 years a comprehensive regulatory framework for radioactive substances in the UK has been progressively introduced, important initial milestones being the white paper Cmnd 884 and the Radioactive Substances Act 1960. During the 1970s and 1980s there were a succession of enquiries and white papers which developed from the growing awareness of the problems of the nuclear waste legacy. This was followed by a comprehensive policy white paper in 1995: Cm 2919. In 1990, 1993, 1995 and 2005 some aspects of the 1960 Act were updated. The most recent, and most radical, modernisation took place in 2010, when the Act was incorporated into the Environmental Permitting Regulations, in England and Wales. Currently a major review of the exemption orders and exclusion criteria under the radioactive substances legislation is close to completion, which will complete the current phase of modernisation of the regulatory framework.
