language processing have been implicated in stuttering, as well as those which subserve motor programming, motor execution and coordination.)
- From a conceptual perspective also, the relationship between lan-guage and speech is awkward. Models of language processing cannot easily account for the conversion of abstract (and therefore timeless) linguistic units into the physical realities of motor speech movements which operate in real time. Action theory and articula-tory phonology offer alternative explanations of the relationship between linguistic and motor speech activities.
- The covert repair hypothesis (Kolk & Postma, 1997; Postma & Kolk, 1993) and the EXPLAN model of Buency failure (Howell & Au-Yeung, 2002) offer opposing perspectives on stuttering development. The covert repair hypothesis assumes that stuttering is related to an error-prone phonological system, whilst EXPLAN argues that the planning and execution processes are out of synchrony.
- It may be useful to consider linguistic factors in stuttering within the framework of a demands and capacities model of the disorder.

This is quite specialized, but is strongly recommended for those interested in knowing more about action theory and task dynamic modelling, which provides the framework for testing action theory concepts. Although this paper is focused more on speech kinematics, and therefore the articulatory outcome of language processing, it is none¬theless an interesting read from a linguistic perspective as it sets out the case for the idea that linguistic units and motor speech representations do not exist
