 : </b>Systems\, states\, trajectories\, and forces: on a dynamical vocabula

 >Abstract</b>: Many theories of phonological representation make use of hie
 rarchical structure schemas comprised of segments\, syllables\, and syllabl
 e-internal constituents such as onsets\, nuclei\, codas\, and rimes\, or mo
 ras. An examination of the conceptual metaphors that underlie such schemas 
 calls into question their utility for understanding the temporal organizati
 on of action in speech. This talk contrasts the metaphors of this more trad
 itional\, structural conception with those of a dynamical vocabulary\, in w
 hich the states of hypothesized systems evolve in time according to change 
 rules that incorporate system interactions. From this perspective\, it is a
 rgued that the temporal organization of action can be understood parsimonio
 usly with just two types of systems\, gestural systems and vocal tract cont
 rol systems\, in combination with the incorporation of internal and externa
 l feedback mechanisms in change rules. This theory is applied to explain cr
 oss-linguistic variation in phonological and phonetic patterns associated w
 ith the moraic status of codas and word-initial consonant clusters. A notab
 le consequence of the theory is that hierarchical structure schemas do not 
 describe temporal organization in any particular utterance\; rather\, they 
 summarize a recurring developmental progression in which the learning of in
 ternal predictive sensorimotor models allows actions that are competitively
  controlled early in development to become coordinatively controlled.</p></
