Traditional approaches to human information processing tend to deal with perception and action planning in isolation, so that an adequate account of the perception-action interface is still missing On the perceptual side, the dominant cognitive view largely underestimates, and thus fails to account for, the impact of action-related processes on both the processing of perceptual information and on perceptual learning On the action side, most approaches conceive of action planning as a mere continuation of stimulus processing, thus failing to account for the goal-directedness of even the simplest reaction in an experimental task We propose a new framework for a more adequate theoretical treatment of perception and action planning, in which perceptual contents and action plans are coded in a common representational medium by feature codes with distal reference Perceived events (perceptions) and to-be-produced events (actions) are equally represented by integrated, task-tuned networks of feature codes – cognitive structures we call event codes We give an overview of evidence from a wide variety of empirical domains, such as spatial stimulus-response compatibility, sensorimotor synchronization, and ideomotor action, showing that our main assumptions are well supported by the data

We have argued that dynamically defined articulatory gestures are the appropriate units to serve as the atoms of phonological representation. Gestures are a natural unit, not only because they involve task-oriented movements of the articulators, but because they arguably emerge as prelinguistic discrete units of action in infants. The use of gestures, rather than constellations of gestures as in Root nodes, as basic units of description makes it possible to characterise a variety of language patterns in which gestural organisation varies. Such patterns range from the misorderings of disordered speech through phonological rules involving gestural overlap and deletion to historical changes in which the overlap of gestures provides a crucial explanatory element.Gestures can participate in language patterns involving overlap because they are spatiotemporal in nature and therefore have internal duration. In addition, gestures differ from current theories of feature geometry by including the constriction degree as an inherent part of the gesture. Since the gestural constrictions occur in the vocal tract, which can be charactensed in terms of tube geometry, all the levels of the vocal tract will be constricted, leading to a constriction degree hierarchy. The values of the constriction degree at each higher level node in the hierarchy can be predicted on the basis of the percolation principles and tube geometry. In this way, the use of gestures as atoms can be reconciled with the use of Constriction degree at various levels in the vocal tract (or feature geometry) hierarchy.The phonological notation developed for the gestural approach might usefully be incorporated, in whole or in part, into other phonologies. Five components of the notation were discussed, all derived from the basic premise that gestures are the primitive phonological unit, organised into gestural scores. These components include (1) constriction degree as a subordinate of the articulator node and (2) stiffness (duration) as a subordinate of the articulator node. That is, both CD and duration are inherent to the gesture. The gestures are arranged in gestural scores using (3) articulatory tiers, with (4) the relevant geometry (articulatory, tube or feature) indicated to the left of the score and (5) structural information above the score, if desired. Association lines can also be used to indicate how the gestures are combined into phonological units. Thus, gestures can serve both as characterisations of articulatory movement data and as the atoms of phonological representation.

Major trends in vowel system inventories

The search for universal tendencies in the languages of the world is a necessary anchor point for any theoretical approach to phonetics. The present typology of vowel systems aims to provide material for testing substance-based theories, including, among others, the Dispersion-Focalization Theory of vowel systems presented in a companion paper (Schwartz, Boe, Vallee & Abry, this issue). It is focused on the economy of vowel systems, specifically the way a system of vowels functions as a whole, and the way vowels interact within a given system. The UPSID (UCLA Phonological Segment Inventory Database, Maddieson, 1984) inventory is analyzed using an original methodology, with the following main results. 1. Vowel systems first exploit a primary system of sounds; with more than 9 vowels, there is a clear trend for exploiting at least one new dimension (secondary systems). 2. Primary systems mainly contain 3 to 9 vowels, and secondary systems 1 to 7 vowels, both with a preference for 5 vowels. 3. In both primary and secondary systems, vowels are mainly concentrated at the periphery. For peripheral systems, symmetry (same number of front and back vowels) is the rule; if there is an asymmetry, the number of front vowels is generally greater than the number of back vowels. 4. For interior vowels in primary systems, central vowels are preferred; among non-central vowels, front rounded vowels are twice as frequent as back unrounded ones. 5. Schwa is the preferred interior vowel, and it does not seem to interact with other sounds within vowel systems.
