“…This view of speech has been proposed by those researchers that are attempting to unify linguistics, phonetics and speech motor control by focusing on physical actions. For instance, Kelso, Saltzman and Tuller (1986) outlined the coordinative structures for speech to be dynamically defined in a unitary manner. The approach is known as the dynamic systems approach, and a key concept in it is the coordinated structure.…”

Why early linguistic milestones are delayed in children with Williams syndrome: late onset of hand banging as a possible rate–limiting constraint on the emergence of canonical babbling

In the present study, eight children with Williams syndrome were observed every 2 weeks between 6 months and 30 months of age when interacting with their mothers. When the collected data were transcribed in terms of both linguistic and motor activities, overall delay was found in terms of the onset of canonical babbling, first words, as well as various motor milestones in every child. The degree to which acquisition of each of the milestones was delayed was individually variable. Nevertheless, the onset of hand banging was found to be an indicator that predicted the onset of canonical babbling consistently among the children. Once canonical babbling was produced, moreover, the onset of first words was recorded during a following 2 to 3 month period. These findings appear to indicate the possibility that development of the motor ability to perform such rhythmic motor activity as hand banging acted as a control parameter for production of canonical syllables in the children.

“…However, even within traditional (serial) frameworks, the representation of serial order and the interaction of a serial input or output with higher levels of representation presents challenges. For example, in models of motor activity, an important issue is whether the action plan is a literal specification of the output sequence, or whether the plan represents serial order in a more abstract manner (e.g., Fowler, 1977Fowler, ,1980 Jordan & Rosenbaum, 1988; Kelso, Saltzman, & Tuller, 1986; Lashley, 1951; MacNeilage, 1970; Saltzman & Kelso, 1987). Linguistic theoreticians have perhaps tended to be less concerned with the representation and processing of the temporal aspects to utterances (assuming, for instance, that all the information in an utterance is somehow made available simultaneously in a syntactic tree); but the research in natural language parsing suggests that the problem is not trivially solved (e.g., Frazier & Fodor, 1978; Marcus, 1980).…”

Finding structure in time

Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather than explicitly (as in a spatial representation). The current report develops a proposal along these lines first described by Jordan (1986) which involves the use of recurrent links in order to provide networks with a dynamic memory. In this approach, hidden unit patterns are fed back to themselves: the internal representations which develop thus reflect task demands in the context of prior internal states. A set of simulations is reported which range from relatively simple problems (temporal version of XOR) to discovering syntactic/semantic features for words. The networks are able to learn interesting internal representations which incorporate task demands with memory demands: indeed, in this approach the notion of memory is inextricably bound up with task processing. These representations reveal a rich structure, which allows them to be highly context-dependent, while also expressing generalizations across classes of items. These representations suggest a method for representing lexical categories and the type/token distinction. I would like to thank Jay McClelland, Mike Jordan, Mary Hare, Dave Rumelhart, Mike Mozer, Steve Poteet, David Zipser, and Mark Dolson for many stimulating discussions. I thank McClelland, Jordan, and two anonymous reviewers for helpful critical comments on an earlier draft of this article.

“…Are there structures of speech which, like passive dynamic gaits, form spontaneously out of the physics of the vocal tract, already providing a highly constrained space of forms in which speech communication principles can carve signals? A theoretical exploration in this direction has been the dynamical systems approach to speech motor control elaborated by Kelso et al (Kelso et al, 1986). Such a perspective partially questions the scope of modeling approaches that aim to predict precisely the forms of speech without relying on a detailed model of the physics of the vocal production system.…”

International audienceThis article discusses open scientific challenges for understanding development and evolution of speech forms , as a commentary to Moulin-Frier et al. (Moulin-Frier et al., 2015). Based on the analysis of mathematical models of the origins of speech forms, with a focus on their assumptions , we study the fundamental question of how speech can be formed out of non-‐speech , at both developmental and evolutionary scales. In particular , we emphasize the importance of embodied self-organization , as well as the role of mechanisms of motivation and active curiosity-driven exploration in speech formation. Finally , we discuss an evolutionary-‐developmental perspective of the origins of speech
